A protective property trust, sometimes called a property protection trust or an interest-in-possession trust of a home, is most often a clause in a will. It leaves your share of the family home in trust rather than outright, so a surviving partner can usually carry on living there while your share ultimately passes to the people you have chosen.
It is a mainstream, long-established form of will planning in England and Wales, and it fits within the wider picture set out in our estate planning guide and our note on Trusts Explained. This article covers what the trust is, how it works, where it helps, its limits, and the important rules around care fees. Any figures are current as at July 2026 and are subject to change.
What is a protective property trust?
A protective property trust is an arrangement, usually written into a will, under which your share of the home is held by trustees rather than passing directly to another person. A named beneficiary, often a surviving spouse or partner, is typically given the right to live in the property for life or until another trigger, after which your share passes to the people you have named, such as children. In HMRC's technical sense a protective trust protects the beneficiary, not the asset (HMRC Inheritance Tax Manual, as at July 2026, subject to change).
How does a protective property trust work?
The mechanism rests on how the home is owned. Couples who want this planning generally hold the property as tenants in common, so each owns a distinct share that can be dealt with separately by their will. On the first death, that share passes into the trust instead of to the survivor outright, and the will sets out who may live there and who eventually benefits.
- Sever the joint tenancy. The home is held as tenants in common, so each partner owns a defined share rather than the whole passing automatically by survivorship (gov.uk, joint property ownership, as at July 2026, subject to change).
- Write the trust into each will. Each will leaves that owner's share into a trust rather than to the survivor outright.
- Give a right to occupy. The survivor is typically granted the right to live in the home, often for life, subject to the trust terms.
- Name the ultimate beneficiaries. When the survivor dies, moves out, or another trigger occurs, the deceased partner's share passes to the named beneficiaries.
Because the trust only takes effect on death, it does nothing during your lifetime and can be changed by rewriting the will while you have capacity. This is different from a lifetime trust set up while you are alive.
