Property Trust Will UK (2026): Putting Your Home in a Will Trust — Life Interest Trusts, IHT, and Care Fee Protection

A property trust in a will (also called a 'property protection trust', 'life interest will trust', or 'property will trust') is a trust set up in a will that gives the surviving spouse or partner the right to live in the family home for the rest of their life — while preserving the underlying capital for the children: (1) THE BASIC MECHANISM: instead of leaving the entire house to the surviving spouse absolutely (where it would then form part of their estate and potentially pass to a new partner or be used for care fees), the will creates a LIFE INTEREST TRUST. The trust works as follows: (a) on the first death, the deceased's SHARE of the property passes into the trust (not to the surviving spouse absolutely); (b) the surviving spouse becomes the LIFE TENANT — they have the right to live in the property for the rest of their life; (c) the CHILDREN (or other named beneficiaries) are the REMAINDERMEN — they will receive the property (or the deceased's share) on the death of the life tenant; (2) TENANCY IN COMMON — A PREREQUISITE: the property trust mechanism only works if the property is held as TENANTS IN COMMON — not joint tenants. As tenants in common, each owner has a distinct share that can be left by will (typically 50% each for a couple). A joint tenancy must be severed before the trust can take effect. The severance is recorded in the Land Registry; (3) WHAT THE LIFE TENANT RECEIVES: the life tenant (surviving spouse) typically has the right to: (a) occupy the property rent-free; (b) in some trusts, receive the rental income if the property is let; (c) in some trusts, move to a new property using the trust capital (a portable life interest); (4) WHAT THE REMAINDERMEN RECEIVE: on the death of the life tenant, the trust capital (the property or its sale proceeds) passes to the remaindermen (typically the children) — either directly or held on further trusts.

The IHT treatment of a property will trust is nuanced and depends on the TYPE of life interest trust created: (1) IMMEDIATE POST-DEATH INTEREST (IPDI): a life interest created in a will for a surviving spouse is treated as an IMMEDIATE POST-DEATH INTEREST (IPDI) under IHTA 1984 s.49A (as amended by Finance Act 2006). An IPDI is a QUALIFYING INTEREST IN POSSESSION — it is treated as if the life tenant OWNS the underlying trust property for IHT. This means: (a) the trust property is treated as part of the SURVIVING SPOUSE'S estate; (b) when the surviving spouse dies, the trust property (including the trust's share of the property) is AGGREGATED with the survivor's estate for IHT; (c) the SPOUSE EXEMPTION (IHTA 1984 s.18) applies on the FIRST DEATH — no IHT is payable when the first spouse dies and leaves their share into an IPDI for the surviving spouse; (2) RNRB INTERACTION — KEY PLANNING POINT: the Residence Nil Rate Band (RNRB) is available for property that is 'closely inherited' — i.e. inherited by lineal descendants (children, grandchildren). An IPDI life interest trust DOES qualify the property for the RNRB on the SECOND DEATH if the remaindermen are lineal descendants (children). This means: (a) RNRB of £175,000 (plus any transferred RNRB from the first death) can apply on the second death to the trust property; (b) the RNRB condition is satisfied because the property passes to children on the life tenant's death — they are 'closely inheriting'; (3) IHT ON THE SECOND DEATH: when the surviving spouse (life tenant) dies, the trust property is aggregated with their estate. The usual NRB and RNRB (and any transferred NRB/RNRB from the first death) apply. For most couples, the combined NRB of £650,000 plus combined RNRB of £350,000 means IHT is not payable on estates below £1,000,000; (4) NON-SPOUSE LIFE TENANT — DIFFERENT IHT TREATMENT: if the life tenant is NOT a spouse (e.g. a cohabiting partner), the IHTA s.18 spousal exemption does NOT apply on the first death. The first spouse's share transferred into the trust is a chargeable lifetime transfer (if created inter vivos) or chargeable on death. Take specialist advice.

The question of whether a property will trust protects against care fees is one of the most frequently asked — and most misunderstood — in estate planning: (1) THE BASIC ARGUMENT — PROTECTING HALF THE PROPERTY: a property will trust argues that the deceased's SHARE of the property is no longer owned by the surviving spouse — it is held in trust for the children. Therefore, the surviving spouse's assessable assets for care fee purposes include only THEIR OWN SHARE of the property — not the trust's share; (2) THE LEGAL REALITY — DELIBERATE DEPRIVATION: local authorities have wide powers to assess what assets a person has deprived themselves of 'for the purpose of avoiding care costs' — the DELIBERATE DEPRIVATION rule under the Care Act 2014 and the Care and Support (Charging and Assessment of Resources) Regulations 2014. If a local authority concludes that the property trust was set up with the purpose of avoiding care fees, it can: (a) treat the trust share as if it were still owned by the surviving spouse; (b) include it in the financial assessment for care; (c) there is NO time limit on deliberate deprivation assessments — unlike the 7-year IHT rule; (3) TIMING MATTERS — CURRENT OR FUTURE CARE NEED: a property trust set up when both spouses are fit and healthy, with no current care needs, is much harder to challenge as deliberate deprivation. A trust set up when one spouse has already been diagnosed with dementia (and care is clearly on the horizon) is far more vulnerable; (4) THE LIFE TENANT'S RIGHT TO OCCUPY: if the surviving spouse is living in the property as life tenant, the LOCAL AUTHORITY CANNOT FORCE A SALE of the trust's share during the life tenant's lifetime — because the trust share is not beneficially owned by the surviving spouse. The life tenant's own share, however, is still assessable; (5) REALISTIC EXPECTATIONS: a property trust in a will is NOT a guaranteed shield against care fees. It adds a layer of protection that may be effective — particularly if established at a time with no foreseeable care need. It is one element of a broader estate plan, not a complete solution.

Setting up an effective property will trust requires actions during the owner's LIFETIME, not just on death: (1) CONFIRM CURRENT TITLE — TENANCY IN COMMON: the first step is to check whether the property is held as JOINT TENANTS or TENANTS IN COMMON. The form of title can be checked: (a) online at HM Land Registry (search by title number or address — registered titles usually have a restriction noting the form of co-ownership); (b) by inspecting the proprietorship register. If the property is held as JOINT TENANTS, the right of survivorship means the survivor automatically inherits the whole property on the first death — the will trust has no effect on the joint tenancy share; (2) SEVERING THE JOINT TENANCY: if the property is held as joint tenants, the joint tenancy must be SEVERED before death. Severance can be done unilaterally by one co-owner without the other's consent — by serving a written notice of severance on the other co-owner (Land Registration Act 2002 and LPA 1925 s.196). After severance, the property is held as tenants in common in equal shares (or in such proportions as the parties agree); (3) LAND REGISTRY — FORM A RESTRICTION: after severance, a FORM A RESTRICTION should be entered at the Land Registry on the property's title: 'No disposition of the registered estate by a sole proprietor (not being a trust corporation) under which capital money arises is to be registered except under an order of the registrar or of the court'. This restriction prevents the surviving spouse from selling without involving a second trustee (or trust corporation) — which protects the trust's interest; (4) UPDATE BOTH WILLS: both spouses should update their wills to include the life interest trust clause directing their share of the property into the trust on death. The will should identify the life tenant, the trustees, and the remaindermen (and substitute remaindermen); (5) TRUSTEES AND TRUST ADMINISTRATION: the trustees of the property trust are usually the surviving spouse and one of the children (to give the children oversight). The trustees must: (a) maintain insurance on the property; (b) keep accounts; (c) comply with the trust deed; (d) consider and give effect to the life tenant's right of occupation.

A property will trust is not right for everyone. Key risks and disadvantages include: (1) COMPLEXITY AND COST OF ADMINISTRATION: a trust requires trustees, trust accounts, and potentially annual tax returns (SA900) — even if the only asset is a share of the family home. The ongoing administrative burden and cost may not be proportionate for smaller estates. Professional trustee fees can erode the benefit over time; (2) DIFFICULTY SELLING THE PROPERTY: if the surviving spouse wants to sell the family home (e.g. to downsize or to move into care), BOTH the surviving spouse (as owner of their own share) AND the trustees (as owners of the trust share) must agree to the sale. If there is a dispute between the trustee-children and the surviving spouse, the property cannot be sold without a court order. This can cause practical difficulty; (3) STAMP DUTY LAND TAX ON NEW PROPERTY — 'PORTABLE' TRUSTS: if the life tenant is able to reinvest the trust proceeds into a new property, the trust holds its share of the new property. SDLT on the new purchase must be carefully considered — the trustees' acquisition of a share may attract the higher SDLT rates for additional dwellings; (4) THE RNRB DOWNSIZING ADDITION: if the surviving spouse sells the trust property and does not replace it with a qualifying residence for RNRB purposes, the RNRB downsizing addition rules may allow the RNRB to still apply — provided certain conditions are met. Take specialist advice; (5) CARE FEES — NOT A GUARANTEED SHIELD: as discussed above, local authorities can assess the trust share as deliberate deprivation if the trust was created with the purpose of avoiding care fees; (6) FAMILY RELATIONSHIP RISK: where the trustees are adult children and the life tenant is the surviving parent, any family breakdown can make trust administration extremely difficult — particularly where the surviving parent forms a new relationship. The trust deed should include clear provisions for dispute resolution.
