A property protection trust (PPT) is a legal arrangement set out in a will. It lets one person, usually a surviving spouse or civil partner, continue living in a shared property for their lifetime, while ensuring the property itself passes to named beneficiaries when that person dies. If a will you are administering includes one, the probate process will be a little more involved. This article explains how a property protection trust works, why people set them up, and what executors and trustees need to know about how inheritance tax (IHT) is managed and the practical steps probate requires.
Because property protection trusts are rarely straightforward, professional legal advice is strongly recommended for anyone dealing with one.
How a property protection trust works
When a couple owns a property as tenants in common, each person holds a defined share. Neither share passes automatically to the other on death. That structure makes it possible to leave a share of the property in a trust by will.
Under a property protection trust, the deceased’s share of the home transfers to trustees on death. The surviving partner holds a life interest, meaning they have the right to live there for the rest of their life. The trustees hold the deceased’s share for the ultimate beneficiaries, typically children or other relatives. The surviving partner enjoys the home but never owns the deceased’s share outright.
Here is an example:
Robert and Susan own their home as tenants in common, each holding 50 per cent. Robert’s will includes a property protection trust. When Robert dies, Susan is entitled to continue living in the house. Robert’s half transfers to the trustees, who hold it on trust for the children. When Susan later dies, Robert’s half passes to the children under the terms of the trust. Susan’s own half is dealt with separately under her will.
Because the surviving partner never owns the deceased’s share, that share is protected from later events in the survivor’s life, such as remarriage or creditors, while still providing security of occupation.
Why people set up a property protection trust
People set up property protection trusts to achieve specific outcomes. The most common reasons are:
- Protecting a share of the property from care-fee assessments. Since the surviving partner does not own the deceased’s share, that share may not be counted when a local authority assesses the survivor’s assets for care-home funding purposes. This can preserve more of the estate for the intended beneficiaries. However, this is not guaranteed: a local authority may apply the deprivation of assets rules under the Care Act framework, which sit in the Care and Support (Charging and Assessment of Resources) Regulations 2014 and Annex E of the statutory guidance, if it concludes the arrangement was set up primarily to avoid care costs. Always take qualified legal advice before relying on this as a planning strategy.
- Securing an inheritance for children from a previous relationship. The trust ring-fences the deceased’s share for the named beneficiaries, regardless of whether the surviving partner later remarries or changes their will.
- Contributing to inheritance tax planning. A property protection trust can form part of a broader IHT strategy, particularly for larger estates. Holding a share in trust does not of itself create or preserve an allowance, so it is worth being precise about what happens. Where the survivor takes a life interest, the spouse exemption applies on the first death, the first spouse’s nil rate band is preserved and can be claimed as a transferable band on the second death, and the trust property is treated as part of the survivor’s estate at that point.
What are the implications for probate?
When a will contains a property protection trust, probate involves several additional steps compared with a straightforward estate. Here is how the process typically unfolds.
Identifying the trust clause
Executors must first identify and understand the property protection trust clause in the will. This means confirming who the trustees are, who holds the life interest (usually the surviving partner), and who the ultimate beneficiaries are.
Transferring ownership to the trustees
Once probate has been granted, executors must transfer the deceased’s share of the property into the trustees’ names. This involves updating the property title at HM Land Registry and keeping clear records of the transfer in the estate accounts.
Trustees’ ongoing responsibilities
After the transfer, trustees take on continuing duties. These include:
- Ensuring the surviving partner can enjoy uninterrupted occupancy.
- Maintaining the property and making decisions about upkeep and repair.
- Registering the trust with HMRC and meeting all tax compliance obligations.
On the point of registration, the deadline is commonly misstated. Because a property protection trust arises under a will, it is excluded from registration for two years from the date of death, for as long as it holds only property from the estate. If the trust is still in existence at that point, the trustees have 90 days from the two-year anniversary of the death to register with HMRC’s Trust Registration Service (TRS), which works out at two years and 90 days in total.
Two things cut that short. If the trust takes in property from outside the estate it loses the exclusion, and if a UK tax liability arises during the two years the trust has to register as a taxable trust regardless.
The TRS records details about the trust’s settlor, trustees, beneficiaries and assets. The penalty for failing to register is £5,000 per trust under Part 9 of the Money Laundering Regulations 2017. It is discretionary rather than automatic: HMRC normally issues a warning letter first and only charges where the trustees then fail to register or to explain why registration is not required.
How a property protection trust affects the probate timeline
The additional administration means probate will generally take longer than for a simple estate. Trustees need to open separate trust bank accounts and keep precise, ongoing records. In complex cases, the extra paperwork can extend the process by several weeks or more.
Tax implications of a property protection trust
IHT planning around property protection trusts involves several connected rules. Here is the current position as of the 2026/27 tax year.
Spousal exemption and the life interest
For IHT purposes, the life tenant of a property protection trust is treated as inheriting the trust property on the death of the person who made the will. Where the life tenant is the deceased’s surviving spouse or civil partner, the spouse exemption applies and defers any IHT until the life tenant’s own death. The mechanism is an immediate post-death interest under section 49A of the Inheritance Tax Act 1984, which is both why the spouse exemption applies on the first death and why the trust property comes back into the survivor’s estate on the second.
IHT on the second death
When the life tenant dies, everything in the property protection trust is revalued and included in their estate for IHT purposes. The usual nil-rate band and residence nil-rate band allowances then apply to the combined estate.
Current allowances
For the 2026/27 tax year, the nil-rate band (NRB) is £325,000 per person, frozen at that level since 2009 and confirmed frozen until 5 April 2031. The residence nil-rate band (RNRB) of £175,000 applies on top where a qualifying home passes to direct descendants, giving a potential individual threshold of £500,000.
A married couple can potentially pass on up to £1,000,000 free of IHT, combining £650,000 of NRB with £350,000 of RNRB, provided they meet specific conditions.
The residence nil-rate band and property protection trusts
Where a property protection trust is used between married couples or civil partners, the RNRB can apply if the deceased’s share of the home passes ultimately to direct descendants, such as children. The timing is what trips people up: the residence nil-rate band is claimed on the life tenant’s death, when the trust property forms part of their estate and passes to the descendants, not on the first death.
There is a related trap worth planning around. Because the trust brings the deceased’s share back into the survivor’s estate, the combined value can cross the £2 million taper threshold, at which point the residence nil-rate band tapers away by £1 for every £2 over. That threshold is frozen alongside the allowances themselves, so a property that keeps rising in value can quietly erode the relief the trust was meant to protect.
This matters more each year: the freeze on both allowances means more ordinary families are drawn into IHT as property values rise.
Tax planning around property protection trusts intersects with other estate planning elements. The rules are detailed, and errors can be costly. Always seek tailored advice from a qualified estate planning professional.
Potential disadvantages of a property protection trust
Property protection trusts offer real benefits, but they also carry drawbacks that are worth understanding before one is set up.
- Reduced flexibility. Once established, the trust terms are difficult to change. If the surviving partner’s circumstances shift significantly, the fixed terms may limit options.
- Ongoing administrative costs. Trustees must maintain accurate records, file any required tax returns, and may need regular legal advice. All of this carries cost.
- Potential for conflict. Disagreements can arise between trustees, the life tenant, and the ultimate beneficiaries over property management and maintenance decisions.
These are reasons to plan carefully at the outset and to involve a qualified solicitor both when drafting the will and when administering the trust.

Frequently asked questions
Does a property protection trust avoid inheritance tax altogether?
No. A property protection trust does not remove IHT liability. Where the life tenant is the deceased’s spouse or civil partner, the spousal exemption defers IHT until the life tenant’s own death. At that point, the trust property is revalued and added to the life tenant’s estate. The combined nil-rate band (£325,000 per person) and residence nil-rate band (£175,000 per person), both frozen until at least 2031, then apply as normal. A property protection trust can support broader IHT planning, but it does not eliminate the tax on its own.
Does a property protection trust protect the family home from care-home fees?
It can help, but there is no guarantee. Because the surviving partner does not own the deceased’s share of the property, that share may not be included in a local authority means test. However, if the local authority considers the arrangement was set up primarily to avoid care costs, it may apply the deprivation of assets rules under the Care Act framework and assess the survivor as though they still hold the asset. Always take specialist legal advice before treating a property protection trust as a care-fees planning tool.
Does the trust need to be registered with HMRC?
Yes, in most cases, but not immediately. Because the trust is created by a will, it is excluded from registration for two years from the date of death while it holds only estate property. If it is still running then, the trustees have 90 days from the two-year anniversary of the death to register with HMRC’s Trust Registration Service. Adding property from outside the estate, or a UK tax liability arising within the two years, ends the exclusion early. The penalty for failing to register is £5,000 per trust, charged at HMRC’s discretion and normally only after a warning letter. The rules were updated by the Money Laundering and Terrorist Financing (Amendment) Regulations 2026, in force from 30 June 2026.
Can the terms of a property protection trust be changed after it is set up?
Generally, no. Once created, the terms of a property protection trust are difficult to vary. This is one of the key disadvantages of the arrangement. If the surviving partner’s circumstances change, for example if they need to sell the property and move, the trustees may need to act within the constraints of the original trust deed. In some situations it may be possible to apply to court for a variation, but this is rarely straightforward or cheap. Taking detailed legal advice when the will is drafted avoids many of these difficulties later.
