Definition
A vested interest is a guaranteed right to property or assets under a will or trust that cannot be taken away, even if the beneficiary must wait to receive it.
Understanding vested interests is crucial because they determine what rights beneficiaries have, whether those rights can be enforced, and what happens if a beneficiary dies before receiving their inheritance.
What Does Vested Interest Mean?
Under UK trust and equity law, a vested interest means a beneficiary has an indefeasible right to property—meaning it cannot be taken away without their consent. According to HMRC guidance (TSEM6210), "a beneficiary has a 'vested' interest in settled property if his entitlement is indefeasible." Unlike a contingent interest, a vested interest requires no conditions to be met. The beneficiary will definitely receive their entitlement, even if they must wait for certain events like estate administration or another person's death.
There are two types of vested interests. A vested interest in possession gives immediate access to property or income. Sarah's will leaves her investment portfolio to husband David for life—David has vested interest in possession, receiving trust income immediately. A vested interest in interest (vested remainder) guarantees future enjoyment. Their son James will receive the trust capital when David dies—James's right is certain, but he must wait for David's death.
The critical feature is what happens if the beneficiary dies before receiving the property. Michael leaves his £320,000 house to daughter Rebecca. If Rebecca dies during probate, her vested interest passes under her own will to her beneficiaries—it doesn't revert to Michael's estate. This contrasts with contingent interests. Thomas leaves "£100,000 to nephew Oliver" (vested) and "£100,000 to niece Emma if she reaches age 25" (contingent). If Emma dies at 24, her interest fails. If Oliver dies during administration, his vested interest passes under his will.
Beneficiaries with vested interests have enforceable legal rights to require proper administration. However, "vested" doesn't mean "immediate payment"—beneficiaries must wait 6-12 months for estate administration. The vested interest guarantees eventual receipt, not immediate access.
Common Questions
"If I'm named as a beneficiary in my grandmother's will, do I have a vested interest in her estate?" Not yet. While she's alive, you have only a "mere expectancy"—she can change her will at any time. Your interest becomes vested only when she dies, at which point your entitlement becomes fixed and cannot be taken away.
"What's the difference between a vested interest and a contingent interest in a trust?" A vested interest is guaranteed—you will definitely receive it (or your estate will if you die first). A contingent interest depends on meeting conditions that might not happen. "£100,000 to Sarah" is vested, but "£100,000 to Sarah if she reaches age 30" is contingent.
"Can trustees take away my vested interest in a trust fund?" No. Once you have a vested interest, it's indefeasible—meaning it cannot be taken away by trustees or anyone else without your consent. Trustees must manage the trust assets for your benefit and you have legal rights to enforce proper administration.
Common Misconceptions
Myth: If I'm named in someone's will, I have a vested interest in their estate right now.
Reality: You have only a "mere expectancy" until the person dies. They can change their will at any time. Your interest becomes vested only at the moment of their death, when your entitlement becomes fixed and legally enforceable.
Myth: Having a vested interest means I can demand my inheritance immediately after someone dies.
Reality: Even with a vested interest, you cannot demand immediate payment. Beneficiaries must wait for executors to complete estate administration, typically 6-12 months. "Vested" means your entitlement is guaranteed (not contingent), but timing of receipt remains subject to proper estate administration procedures.
