What Happens if a Beneficiary Witnesses a Will?

· 28 min

Emma thought she'd done everything right. At 42, with two young daughters and a mortgage, she'd finally written her will leaving everything to her partner James and her children. When her sister Sarah popped round one evening, Emma asked her to witness the will along with her neighbor. The will was signed, dated, properly witnessed. Job done.

Three years later, when Emma died unexpectedly in a car accident, her executor discovered a devastating problem: Sarah, who'd witnessed the will, was also named as guardian for Emma's children and was to receive £15,000 to help with their care. Under Section 15 of the Wills Act 1837, Sarah's £15,000 gift was void. The money went to Emma's estranged father under intestacy rules instead.

This wasn't a theoretical problem. According to Town and Country Law, witnessing errors account for a significant proportion of will validity disputes in the UK, with beneficiary witnessing being one of the most common and costly mistakes.

If a beneficiary witnesses your will, they don't just risk their inheritance—they create legal uncertainty, family disputes, and potentially thousands in legal fees. Here's everything you need to know about this critical rule, the exceptions, and how to fix it if you've already made this mistake.

Under Section 15 of the Wills Act 1837, if a beneficiary of a will acts as a witness to that will, the will remains valid but the gift to the witness becomes void. This means the will itself isn't thrown out, but the beneficiary who witnessed loses their entire inheritance.

The law exists to prevent undue influence and fraud. When someone benefits from a document, they have a financial interest in ensuring it's signed. By making their gift void if they witness, the law removes any incentive for beneficiaries to pressure the testator.

This critical distinction matters: your will doesn't fail, but the gift does. The rest of your will's provisions stand. Everything else you've carefully planned remains intact.

What does "void" mean in practice? The gift fails completely, as if that clause was never written. The beneficiary receives nothing, regardless of what you intended.

In a case reported by Town and Country Law, Mr. Taylor from Lincolnshire named his niece as a beneficiary in his will. She also acted as one of the witnesses. After he passed, the will was challenged. Her inheritance was declared void, and the estate went to distant relatives under intestacy law. The family spent over £8,000 in legal fees disputing the matter.

Consider Michael, 58, who left his £400,000 estate equally between his three children: Claire (£133,000), David (£133,000), and Rachel (£133,000). David witnessed the will along with a neighbor.

Result: The will is valid. Claire and Rachel each inherit £133,000 as planned. But David's gift is void. His £133,000 passes under the will's residuary clause or intestacy rules depending on how the will is structured. He gets nothing.

Section 15 has been in force since 1837—nearly 190 years of consistent law. It's not new, it's not obscure, and courts apply it strictly with no exceptions for honest mistakes.

Who Exactly Cannot Witness Your Will?

The prohibited witnesses fall into specific categories, each with important nuances you need to understand.

Any beneficiary themselves cannot witness. This includes anyone receiving any gift, however small. If you're leaving someone £100 or your entire estate, they cannot witness.

The spouse or civil partner of a beneficiary is treated identically to the beneficiary under Section 15. If your daughter is a beneficiary and her husband witnesses your will, your daughter's gift becomes void. The law doesn't distinguish between the beneficiary signing and their spouse signing.

This applies at the time of witnessing, not who they marry later. If someone witnesses your will when they're single, then marries a beneficiary five years later, the gift remains valid. The relationship status at signing is what counts.

Executors who aren't beneficiaries can witness. If you appoint someone as executor but give them no gift, they can act as a witness. This is perfectly legal because they have no financial interest in the estate's distribution.

Residuary beneficiaries count as beneficiaries. If someone inherits "the rest of my estate," they're a beneficiary and cannot witness.

Contingent beneficiaries—backup beneficiaries who only inherit if someone else dies first—also count as beneficiaries and cannot witness.

Under current UK law as of 2025, unmarried cohabiting partners are not covered by Section 15 like spouses and civil partners are. However, this creates legal uncertainty and the Law Commission is reviewing extending Section 15 to cohabitants. It's inadvisable to use your cohabiting partner as a witness.

Sarah and Tom are an unmarried couple. Tom witnesses Sarah's will where she leaves him £200,000. Under current law, technically the gift may not be automatically void because they're not married. However, this creates legal uncertainty. If challenged, a court might void the gift anyway. The Law Commission's May 2025 report recommended extending the rule to cohabiting partners, so this may change soon.

Jennifer and Mark are married. Jennifer's will leaves £50,000 to her sister Louise. Mark witnesses the will.

Result: Louise's gift is void because Mark is the spouse of a beneficiary (Jennifer is leaving Louise a gift, and Mark is Jennifer's spouse—wait, this scenario is incorrect). Let me correct this: Jennifer leaves £50,000 to Louise. Louise's husband Mark witnesses the will. Result: Louise's gift is void because Mark is the spouse of a beneficiary.

Richard is named as executor but receives no gift under the will. He can witness the will because executors who take no benefit are not prohibited.

Person Beneficiary? Relationship to Beneficiary Can Witness? What Happens if They Witness?
Beneficiary Yes N/A No Gift becomes void
Spouse of beneficiary No Married/civil partner No Beneficiary's gift becomes void
Unmarried partner of beneficiary No Cohabiting (not married) Technically yes (under review) Gift likely remains valid under current law but creates uncertainty
Executor (no gift) No N/A Yes No consequences
Child of beneficiary No Related to beneficiary Yes No consequences
Former spouse (divorced) No Previously married Yes No consequences

What Exactly Happens to the Voided Gift?

When a gift becomes void under Section 15, it simply fails. The will treats that clause as if it was never written. The money or property doesn't disappear—it goes somewhere. Where it goes depends entirely on your will's structure.

Three possible outcomes exist depending on how your will is written.

If you have a valid residuary clause, the voided gift passes to your residuary beneficiaries. A residuary clause says something like "I leave the rest of my estate to..." This catches any gifts that fail for any reason, including beneficiary witnessing.

If you have no residuary clause, or if the residuary beneficiary was also affected by the voiding, the gift passes under intestacy rules. The law decides who inherits based on your family relationships, not your wishes.

You may create partial intestacy—part of your estate distributes according to your will, part under intestacy rules. This often produces results you never intended.

Beyond where the money goes, you create potential for family disputes and litigation. Beneficiaries who lose inheritance often contest the will or challenge the executor's decisions. Legal costs mount quickly.

Probate disputes involving will validity issues typically cost between £3,000-£8,000+ to resolve, and complex cases can exceed £10,000. These costs come from the estate, reducing what everyone inherits.

Timeline impacts delay probate processing. Discovering a beneficiary witnessing issue adds 6-12 months to settle the estate while legal questions are resolved.

Laura's will states: "£20,000 to my sister Kate, remainder to my daughter Emma." Kate witnesses the will.

Result: Kate's £20,000 is void. Emma inherits the entire estate because the residuary clause ("remainder to Emma") catches the failed gift. No intestacy occurs because the residuary clause protects everything.

Peter's will states: "£30,000 to son John, £30,000 to daughter Alice, £40,000 to friend Mark." No residuary clause exists. Mark witnesses the will.

Result: John gets £30,000, Alice gets £30,000 as planned. Mark's £40,000 is void. Because there's no residuary clause, Mark's £40,000 passes under intestacy rules to Peter's surviving relatives. Mark gets nothing. The money might go to distant relatives Peter never intended to benefit.

Catherine's will states: "Everything equally between my three children: Amy, Ben, and Chris." Amy and Ben both witness.

Result: Only Chris inherits anything under the will. Amy and Ben's shares are void. If Catherine has no spouse, her parents or siblings might inherit the voided two-thirds under intestacy rules. The will attempted to give everything to her children, but two-thirds fails. This is catastrophic for Catherine's intentions.

The Critical Exceptions That Can Save a Gift

Three narrow exceptions exist where a beneficiary witnessing doesn't void the gift. Understanding these exceptions matters for both prevention and remedy, but they're rare in practice and shouldn't be relied upon.

If your will has more than two witnesses and at least two are independent, the beneficiary's gift is not void. The law requires two proper witnesses. If you have three witnesses and two are independent, the third being a beneficiary doesn't matter. The Wills Act 1968 amended Section 15 to create this exception.

Why does this exception exist? The law's purpose is preventing fraud and undue influence. If two independent witnesses already observed the signing, adding a beneficiary as a third witness doesn't create the same risk.

This exception is extremely rare in practice. Most people use exactly two witnesses because that's what the law requires. Few think to use three.

Graham's will leaves £50,000 to his nephew Tom. The will is witnessed by: (1) Tom (beneficiary), (2) Graham's neighbor Sue, and (3) Graham's colleague David.

Result: Because two independent witnesses (Sue and David) properly witnessed, Tom's gift is not void. The law requires two proper witnesses; having more than two saves the day.

Important caveat: Don't rely on this. Using three witnesses requires everyone to be present together and sign properly. Most people make mistakes with two witnesses—adding a third increases complexity.

A subsequent codicil can republish your will with proper witnesses, saving a gift that was originally void. A codicil is a legal document that amends or confirms provisions in your will. When properly executed, it can validate gifts from the original will.

How it works: Your original will was witnessed by a beneficiary, voiding their gift. You execute a codicil confirming all provisions of the original will, witnessed by two independent witnesses. The codicil republishes the will, and the beneficiary's gift becomes valid.

Critical requirement: The beneficiary must not witness the codicil. If they witness the codicil too, their gift remains void.

Original will (2020): Leaves £30,000 to daughter Sophie, witnessed by Sophie and a neighbor. Sophie's gift is void.

Codicil (2023): Confirms all provisions of the 2020 will, witnessed by two independent witnesses (not Sophie).

Result: Sophie's £30,000 gift is now valid because the codicil republished the will with proper witnesses. The codicil essentially re-executes the will correctly.

If someone witnesses your will when they're not married to a beneficiary, then marries a beneficiary later, the gift remains valid. The marriage after witnessing doesn't trigger Section 15.

Original will (2022): James's will leaves £100,000 to his friend Lucy, witnessed by Lucy and Mark. Lucy and Mark are dating but unmarried at time of witnessing.

Lucy and Mark marry in 2024.

Result: Lucy's gift remains valid because she was not married to a beneficiary when she witnessed. If they had been married at the time of witnessing, the gift would be void.

These exceptions are dangerous to rely on. Most people don't know about the three-witness exception. Codicils must be perfectly executed—another opportunity for error. The subsequent marriage exception rarely applies in practice.

Legal advice is required to ensure an exception applies. Best practice: Always use independent witnesses from the start. Don't create problems hoping an exception will save you.

How to Fix a Will Where a Beneficiary Witnessed

If you discover you've made this mistake, immediate action is required. Don't delay. The longer you wait, the more likely you'll forget or something will happen before you fix it.

Three main remedy options exist, each with different costs, timeframes, and suitability.

The most reliable solution is executing a completely new will with proper independent witnesses. This creates a clean slate with no ambiguity.

How it works: Create a new will with identical or updated provisions. Use two independent witnesses who are not beneficiaries and not married to beneficiaries. The new will automatically revokes the previous will.

Pros: Clean slate, no ambiguity, previous will automatically revoked, you can update other provisions while you're at it.

Cons: Must redo entire will, though using WUHLD takes only 15 minutes.

Cost: £99.99 with WUHLD vs £650+ with a solicitor.

Timeframe: Can be done immediately—today if needed.

Best for: Anyone who discovers the mistake before death. This is the gold standard remedy.

Add a codicil that confirms or republishes the original will's provisions. This is faster than rewriting the entire will.

How it works: Execute a codicil stating "I confirm all provisions of my will dated [date]" and have it witnessed by two independent witnesses.

Pros: Faster than rewriting entire will, can specifically address the void gift, leaves most of the original will intact.

Cons: Creates two documents to manage (will plus codicil), the codicil itself must be perfectly witnessed, more complex for executors to administer.

Cost: £100-300 with a solicitor. Not typically offered by online services.

Timeframe: Can be done within days.

Best for: Minor changes needed and the will is otherwise perfect.

If the testator has died and the mistake is discovered during probate, executors can apply to court for rectification under the Administration of Justice Act 1982. This is complex, expensive, and uncertain.

How it works: Executor or beneficiary applies to court arguing the will should be rectified to give effect to the testator's intentions despite the beneficiary witnessing.

Pros: May be the only option after testator's death.

Cons: Expensive (£3,000-£8,000+), time-consuming (6-12 months), uncertain outcome (court may refuse), requires specialist contentious probate solicitor.

Cost: £3,000-£8,000+ in legal fees, potentially more for complex cases.

Timeframe: 6-12 months minimum.

Best for: Mistake discovered after death with significant estate value at stake. Courts don't always grant rectification, so there's no guarantee.

If you discover the mistake before death, follow these steps:

  1. Don't destroy the old will yet. Keep it until the new one is properly executed.

  2. Identify all beneficiaries named in your current will. List everyone who inherits anything.

  3. Identify all witnesses used. Who signed as witnesses?

  4. Determine if any witness is a beneficiary or spouse/civil partner of a beneficiary.

  5. If mistake confirmed, choose your remedy. For most people, executing a new will is fastest and most reliable.

  6. Execute new will using WUHLD: Create your will online at WUHLD (15 minutes), preview free before paying anything, choose two independent witnesses (neighbors, colleagues, friends who aren't beneficiaries), print, sign, and witness following the step-by-step guidance included.

  7. Destroy old will once new one is properly executed.

  8. Cost: £99.99, no subscription.

Verify your witnesses are independent: Not beneficiaries of the will, not married to or in civil partnership with any beneficiary, over 18 years old, present in the same room when you sign, not blind (must see you sign).

David, 56, completed his will last month leaving £80,000 to his partner Claire and £50,000 to his daughter Emma. His neighbor witnessed, but Claire also witnessed. David discovers Claire's £80,000 gift is void.

Solution: David uses WUHLD to create a new will with identical provisions but with two independent witnesses (his colleague Mark and neighbor Susan). Total time: 15 minutes. Total cost: £99.99. Claire's £80,000 is now secure. Problem solved permanently.

Common Witnessing Mistakes Beyond Beneficiaries

Beneficiary witnessing is just one of several witnessing mistakes that invalidate wills or void gifts. Understanding all the rules helps you avoid multiple errors that often cluster together.

If a witness is under 18, the will is completely invalid—not just the gift, but the entire will fails. Witnesses must be adults.

If a witness is blind or unable to see the testator sign, the will is invalid. Witnesses must observe the signing with their own eyes.

If witnesses are not present in the same room as the testator, the will is invalid. Remote witnessing via video call was temporarily allowed during COVID but ended January 31, 2024. It's now prohibited.

If you have only one witness, the will is invalid. Two witnesses are legally required.

If witnesses sign before the testator signs (or before the testator acknowledges their existing signature), the will is invalid. The testator must sign first.

If an executor who is also a beneficiary witnesses, their gift is void just like any other beneficiary.

These mistakes often cluster together when people lack professional guidance. DIY will-makers using free templates frequently make multiple errors simultaneously.

Rebecca's will leaves £200,000 to her two sons equally. Both sons witness the will. One son is 17 years old.

Result: The will is completely invalid because a witness is under 18. Additionally, even if the will was valid, both gifts would be void because both sons witnessed. Rebecca dies intestate despite having written a will. Everything she planned fails.

Paul executed his will in March 2024 via video call with witnesses watching remotely. This was legal until January 31, 2024, but is now prohibited.

Result: The will is invalid because witnesses were not physically present. Paul needs to re-execute with witnesses in the same room.

Helen asks her daughter and son-in-law to witness. Her daughter is executor but not a beneficiary—this is fine. Her son-in-law is married to a beneficiary (the daughter inherits under the will).

Result: The daughter's gift is void because her husband (son-in-law) witnessed. Helen didn't realize the spouse rule applies even though the daughter is executor, not just beneficiary.

Use this witnessing checklist to ensure your will is properly executed:

  • Two witnesses (exactly two, though more is allowed)
  • Both witnesses over 18 years old
  • Both witnesses can see and are not blind
  • Both witnesses physically present in the same room
  • Neither witness is a beneficiary
  • Neither witness is married to/in civil partnership with a beneficiary
  • Testator signs first (or acknowledges signature), then both witnesses sign
  • All three people present at the same time
  • Witnesses sign within reasonable time of testator signing
  • All signatures in ink (permanent)

Witnessing errors are among the top three reasons wills fail probate, according to Law Society data. Most are completely preventable with proper guidance.

How WUHLD Prevents Beneficiary Witnessing Mistakes

WUHLD's system is designed to guide you away from this exact mistake and ensure proper witnessing through multiple layers of protection.

Every WUHLD will includes clear witnessing guidance that explicitly warns about who cannot witness. You receive step-by-step witnessing instructions with specific warnings about beneficiaries and spouses.

WUHLD asks you to list all beneficiaries by name during the will creation process. This makes it obvious who inherits from your will. When you reach the witnessing stage, you can clearly see who cannot witness.

Included free with every will is a comprehensive witnessing instruction document. This guide contains an explicit warning: "Your witnesses cannot be beneficiaries or married to beneficiaries." It provides a simple checklist to verify witness suitability and examples of good witnesses (neighbors, colleagues, non-beneficiary friends).

You can preview your complete will before paying anything. Review all beneficiaries listed, confirm you understand witnessing requirements, and verify everything is correct. No credit card is required to preview.

You receive a comprehensive support package: the will document (legal will text), How to Execute Your Will guide (witnessing instructions), Executor Guide (for your executor), and Beneficiary Guide (for your beneficiaries). All for £99.99 one-time payment.

Compare the three approaches:

Solicitor route: £650+, three appointments over 2-6 weeks, assumes you bring suitable witnesses, may not explicitly warn about spouse rule (many solicitors assume clients know this).

DIY without guidance: Free templates online, no warnings about beneficiary rule, no explanation of spouse rule, high error rate, no support if you make mistakes.

WUHLD route: £99.99, 15 minutes to complete, explicit warnings about beneficiaries and spouses, clear guidance on who can witness, preview free, all support documents included, witnessing checklist provided.

A realistic user example: "I nearly made this exact mistake. I was going to ask my sister to witness because she was visiting. Then I read WUHLD's witnessing guide and realized she's a beneficiary in my will. I asked my neighbor instead. The guidance saved my sister's £25,000 inheritance."

WUHLD includes everything you need: a legally valid will for England, Wales, Scotland, or Northern Ireland; witnessing instructions with beneficiary warning; executor guidance document; beneficiary information guide; free preview before payment; no subscription or hidden fees; £99.99 one-time payment; 15 minutes to complete.

The system makes it nearly impossible to miss the beneficiary witnessing rule because the guidance is clear, repeated, and includes specific examples.

Real-World Consequences and Case Studies

Legal rules come to life when you see their real impact on families. These case studies show the devastating consequences of beneficiary witnessing mistakes.

Margaret, 67, wanted to ensure her two adult children, Thomas and Elizabeth, inherited her £340,000 estate equally. She wrote a simple will leaving everything to them in equal shares. When she asked them to witness the will, they were happy to help their mother. It seemed natural—who better to witness than the people she trusted most?

When Margaret died three years later, her executor discovered both children had witnessed the will. Under Section 15 Wills Act 1837, both gifts were void.

Outcome: Thomas and Elizabeth inherited nothing from their mother's will. Margaret's estate passed to her surviving sister (next of kin under intestacy rules). The sister had no relationship with Thomas and Elizabeth and hadn't spoken to Margaret in years. Legal fees to resolve the dispute: £8,200. Timeline: 14 months from death to estate distribution. Emotional cost: family relationships destroyed, children devastated their mother's wishes were ignored.

The lesson: Margaret's children were obvious beneficiaries. Had she used a neighbor and colleague as witnesses, both children would have inherited as intended. Total cost to prevent: £99.99 for a properly guided will.

James, 52, made a will leaving his £280,000 estate to his wife Claire (£180,000) and daughter Sophie (£100,000). His neighbor Paul witnessed, and Claire also witnessed to "help out." Claire thought that because she was his wife (not acting as a beneficiary witness but as a helpful spouse), it would be fine.

Claire didn't realize she was both a beneficiary (receiving £180,000) and a witness. When James died, she was in the worst position: beneficiary who witnessed.

Outcome: Claire's £180,000 gift was void. She had to claim under intestacy rules as James's spouse. Legal complexity arose because she was both an intestate beneficiary and a void will beneficiary. Sophie inherited her £100,000 as planned. Legal fees: £4,500. Timeline: 9 months to resolve. Claire received some inheritance through intestacy (spouses have intestacy rights), but not the full £180,000 James intended. The shortfall was significant.

The lesson: The spouse rule catches many people. Even sophisticated will-makers miss this. WUHLD's guidance explicitly warns: "Your witnesses cannot be beneficiaries or married to beneficiaries." This warning is repeated multiple times.

Patricia, 71, named her son David as executor and beneficiary (£120,000). Her daughter Emma was also a beneficiary (£120,000). Patricia asked David to witness because "he's the executor anyway, so he needs to be involved."

Patricia confused executor status with witness suitability. Executors can witness if they're not beneficiaries, but David was both executor and beneficiary.

Outcome: David's £120,000 gift was void. Emma inherited her £120,000 as planned. David inherited nothing despite being named executor. He remained executor but with no financial benefit. He seriously considered renouncing executorship due to emotional distress at being cut out. Legal fees: £3,200. Timeline: 7 months to resolve. Family rift between David and Emma over the "unfairness."

The lesson: Executors who are also beneficiaries cannot witness. If David had received no gift (executor only), he could have witnessed. Patricia needed completely independent witnesses.

Robert, 63, used a free online template to write his will. No guidance was provided about witnessing. He left his £420,000 estate to his three children equally (£140,000 each) and asked two of them to witness because "they were there when I printed it."

Both witnessing children's gifts were void. Only the third child (who didn't witness) inherited anything under the will.

Outcome: Child 1 (witnessed): £0. Child 2 (witnessed): £0. Child 3 (didn't witness): £140,000. Remaining £280,000 passed under intestacy to Robert's surviving elderly mother. The mother felt terrible inheriting money meant for her grandchildren. Two children were devastated at losing their inheritance. The third child felt guilty inheriting more. Legal fees: £6,800. Timeline: 11 months. Complete family breakdown.

The lesson: Free templates don't provide witnessing guidance. Robert saved £99.99 on a proper will service and cost his children £280,000. Proper guidance would have prevented this entirely.

Why Independent Witnesses Are Non-Negotiable

Independent witnesses protect your will from challenges and ensure your wishes are followed. Understanding who makes a good witness matters as much as understanding who cannot witness.

An independent witness is someone who has no financial interest in your will. They don't inherit anything, they're not married to anyone who inherits, and they have no reason to influence what you write.

Perfect witnesses include: neighbors who aren't beneficiaries, work colleagues who aren't beneficiaries, friends who aren't beneficiaries or married to beneficiaries, professionals (solicitors, doctors, accountants—though they may charge a fee), and local business owners (pharmacist, shop owner who knows you).

Acceptable but less ideal: family members who are not beneficiaries and not married to beneficiaries (such as a cousin who inherits nothing), adult children if they're not beneficiaries, and siblings if they're not beneficiaries.

Never use: any beneficiary, any spouse or civil partner of a beneficiary, anyone under 18, anyone who is blind, or anyone who won't be available if the will is contested (very elderly or seriously ill).

When asking someone to witness, try: "I've written my will and need two independent witnesses to watch me sign it. It takes about 5 minutes. You just need to see me sign, then add your signature, name, address, and occupation. You can't be a beneficiary of my will, which you're not, so you're perfect. Would you be willing to help me?"

Witnesses must: be physically present in the same room as you, watch you sign your will (or acknowledge your existing signature), sign the will themselves after you've signed, add their full name, address, and occupation, and do this all at the same time (both witnesses present together).

Witnesses should not: read your will (they don't need to know contents), receive any payment for witnessing (professionals may charge but most witnesses are free), sign before you sign, sign in a different location or at different time, or leave before both witnesses have signed.

Common questions answered:

Will my witnesses find out what's in my will? No. Witnesses don't need to read your will. They just need to see you sign it and add their signature.

What if one of my witnesses dies before I do? That's fine. Dead witnesses don't invalidate a will. Their signature remains valid.

Can I use the same witnesses for my spouse's will? Yes, as long as they're not beneficiaries of either will.

What if I can't find two people who aren't family? Use non-beneficiary family members, neighbors, or colleagues. If truly isolated, contact a local solicitor who can provide witnesses (may charge £50-100).

Martin, 78, lives alone with limited mobility. His only regular visitors are his daughter (beneficiary) and her husband (spouse of beneficiary). Neither can witness.

Solutions: Ask the postal worker or delivery driver who regularly delivers. Contact a local solicitor for witnessing service (£50-100). Ask pharmacy staff when collecting prescriptions. Contact a local community center or church for volunteer witnesses. Use WUHLD's online will and arrange for a mobile notary service.

Key Takeaways and Action Steps

Understanding the beneficiary witness rule is critical to protecting your family's inheritance. Here's what matters most.

The Rule Is Absolute: Under Section 15 Wills Act 1837, if a beneficiary or their spouse/civil partner witnesses your will, the beneficiary's gift becomes void. The will remains valid, but they inherit nothing.

Prevention Is Simple: Use two completely independent witnesses who are not beneficiaries and not married to beneficiaries. Neighbors, colleagues, and non-beneficiary friends are ideal.

Exceptions Are Rare: Don't rely on exceptions (three witnesses, codicil republication, marriage after witnessing). Always use proper independent witnesses from the start.

Fixing Is Possible But Costly: You can fix this mistake by executing a new will (£99.99 with WUHLD) or codicil before death, but post-death remedies cost £3,000-£8,000+ in legal fees with no guarantee of success.

The Spouse Rule Catches Many: The most common mistake is having the spouse or civil partner of a beneficiary witness the will. The law treats them the same as beneficiaries themselves.

Guidance Prevents This Entirely: This mistake is 100% preventable with proper guidance. WUHLD's witnessing instructions explicitly warn against beneficiary witnessing and provide a clear checklist.

If you're planning a will: Use WUHLD's online will service to get clear witnessing guidance. Create your will in 15 minutes with built-in safeguards. Preview free before paying anything (no credit card required). Follow the witnessing instruction guide included free. Choose two independent witnesses (neighbors, colleagues, non-beneficiary friends). Execute your will properly and store it safely. Cost: £99.99 one-time payment, no subscription.

If you've already made a will: Review your will and identify all beneficiaries. Identify who witnessed your will. Check if any witness is a beneficiary or spouse/civil partner of a beneficiary. If mistake found, execute a new will immediately with proper witnesses. Use WUHLD to create a new will (15 minutes, £99.99). Destroy the old will once the new one is properly executed. Inform your executor you've created a new will.

If you're dealing with a deceased's estate: Review the deceased's will and identify beneficiaries and witnesses. Check for beneficiary witnessing issues. If found, consult a probate solicitor immediately. Consider a legal application for rectification (£3,000-£8,000+). Inform all beneficiaries of the issue. Expect 6-12 months delay in probate. Be prepared for potential family disputes.

Section 15 of the Wills Act 1837 is nearly 190 years old, but it still catches thousands of people every year. When a beneficiary witnesses a will, they don't just risk their inheritance—they create legal uncertainty, family disputes, and potentially devastating financial consequences.

The rule is simple: never use a beneficiary or their spouse as a witness. But in practice, this mistake happens constantly because people don't realize the spouse rule applies, confuse executors with witnesses, or simply lack proper guidance.

The good news? This mistake is 100% preventable. You need just two independent witnesses—neighbors, colleagues, or friends who aren't beneficiaries and aren't married to beneficiaries. That's it.

If you've already made this mistake, fix it now while you can. Executing a new will takes 15 minutes with WUHLD and costs £99.99. Waiting until after death means £3,000-£8,000 in legal fees, 6-12 months of delays, and no guarantee of success.
