What Is a Life Interest Trust Will?
A life interest trust will is a will that places your share of an asset — usually the family home — into trust on death. A chosen person (the life tenant) can live there or take the income for life, then it passes to your beneficiaries (the remaindermen).
This guide covers selling property under a life interest, who pays the IHT, what happens when the trust ends, and the life interest trust will template.
It is one of the most powerful tools in UK estate planning — and one of the easiest to get structurally wrong.
Get one step wrong — such as leaving the home as joint tenants rather than tenants in common — and the trust may never bind the property at all.
That single point is why a life interest trust will is usually paired with a severance of joint tenancy.

What Is a Life Interest Trust Will in UK Law?
A life interest trust (also called an interest in possession trust) names two different kinds of beneficiary.
- The life tenant: has the right to occupy the property, or take the income from trust assets, for life.
- The remaindermen: the people who inherit the capital once the life interest ends.
When this trust is created by your will, the life tenant’s interest begins on your death.
In tax terms this is an Immediate Post-Death Interest (IPDI) under section 49A of the Inheritance Tax Act 1984.
Most couples use it to let a surviving spouse stay in the home for life, while ring-fencing the first partner’s share for their children.
The structural condition: the home must be owned as tenants in common, not as joint tenants.
Under a joint tenancy, your share passes automatically to the co-owner on death — regardless of what your will says.
So the joint tenancy is severed first, turning ownership into defined shares your will can then direct into trust.
Our Severance of Joint Tenancy guide explains that step in full.
Is a Living Trust Better Than a Will in the UK?
It depends on what you are trying to protect — and the two are not the same thing.
A lifetime trust (also called a living or inter vivos trust) is set up while you are alive, and you transfer assets into it now.
A life interest trust will creates the trust on your death — nothing moves out of your name during your lifetime.
For most homeowners, putting the family home into a lifetime trust carries real downsides:
- Loss of the Residence Nil-Rate Band: transferring your home into a lifetime trust can forfeit up to £175,000 of allowance per person.
- Capital Gains Tax: moving property into a lifetime trust is a disposal at market value for CGT.
- Stamp Duty: transfers into some trusts can trigger SDLT at higher rates.
The will route avoids those lifetime tax events, because the trust only takes effect when you die.
⚠ Note: a life interest trust will is widely used across the UK, but it is not a guaranteed way to avoid care fees. A local authority can challenge an arrangement it views as deliberate deprivation of assets.
Can You Sell a Property With a Life Interest in the UK?
Yes — but not by the life tenant alone, and not in the same way as a normal home.
The life tenant has the right to occupy the property, but the trustees hold the legal title.
A sale needs the trustees to act, normally with the life tenant’s agreement, since it affects their right to live there.
Where two or more trustees join in the sale, the buyer takes the property free of the trust — this is called overreaching.
The trust then attaches to the sale proceeds instead of the bricks and mortar.
If the life tenant wants to downsize or move into care, the trustees can usually:
- Buy a replacement home for the life tenant to live in.
- Invest the proceeds so the life tenant receives the income instead.
This only works if your will gives the trustees clear power to sell, reinvest, and buy a substitute property.
Those powers are a standard feature of a professionally drafted life interest trust will.
How Much Does It Cost to Set Up a Lifetime Trust in the UK?
Solicitor and estate-planner fees vary widely by trust type, asset value, and complexity.
As a general guide to the UK market in 2026:
- Property protection / life interest trust will: often around £500–£1,500 for a straightforward arrangement.
- More complex trust wills: commonly £2,000–£3,000 where there are multiple assets or tax planning.
- Lifetime trusts: frequently £1,000–£5,000, plus possible ongoing admin of roughly £200–£600 a year.
Figures are indicative market ranges, not our prices, and they change between firms and regions.
The will route is generally the lower-cost path, because the trust is built into your will rather than set up separately now.
How Much Is a Life Interest Trust Will?
A will containing a life interest trust is more involved than a basic will, so the professional route is not cheap.
Through a solicitor, a will with a life interest trust typically costs around £350 to £800, and more for complex estates.
Many firms also bill by the hour, so the final figure climbs with each meeting, revision, and piece of advice.
Our route is different. The Life Interest Trust Will Template is £60.00 as a one-time payment.
- One payment: no subscriptions, no renewals, and no recurring fees.
- Two ways to build it: the guided Interview and the classic Editor, both producing the same document.
- Full preview: see every clause with a watermark before you decide to buy.
- UK law only: drafted for England & Wales, with no US crossover.
- Free lifetime updates: included with your one-time payment.
You only pay when you’re happy with it — preview every template before buying.
We monitor UK law changes, and updated versions appear in your My Templates page when we release them — free, forever.
Because the will depends on severing a joint tenancy first, the two documents are often used together.
The Notice of Severance of Joint Tenancy Template is £15.00 on its own, or take both in the bundle below.
Many people complete a straightforward life interest trust will confidently on their own.
Consider solicitor review for high-value estates or complex family circumstances.
Who Pays the IHT on a Life Interest Trust?
With a qualifying interest in possession, the life tenant is treated for IHT as if they owned the trust capital.
That means no Inheritance Tax falls due simply because the trust is created on your death.
Where the life tenant is your spouse or civil partner, the spouse exemption applies on the first death.
There are no ten-yearly or exit charges while a qualifying IPDI continues.
IHT is assessed when the life tenant dies, when the trust capital is added to their own estate.
Who actually pays: the trustees settle the IHT on the proportion relating to the trust assets, not from the life tenant’s own money.
The remaining tax on the life tenant’s free estate is dealt with by their personal representatives.
As at June 2026, the nil-rate band is £325,000 per person and the residence nil-rate band is up to £175,000.
Both bands are frozen until 5 April 2031, and the residence band needs a qualifying home to pass to direct descendants.
IHT above the available allowances is charged at 40%, or 36% where at least 10% of the net estate goes to charity.
What Happens When a Life Interest Trust Ends?
A life interest trust usually ends on the life tenant’s death.
At that point your protected share passes to the remaindermen named in your will — typically your children.
The trustees either transfer the property to the beneficiaries or sell it and distribute the net proceeds.
For Capital Gains Tax, the trust assets are revalued on the life tenant’s death, so there is no gain or loss to the trustees at that point.
Where the life tenant occupied the home, the trustees may also be able to claim Private Residence Relief on an earlier sale.
Some trusts also end earlier — for example on remarriage or cohabitation — but only where your will is drafted that way.
Can a Life Interest Trust Be Wound Up?
Yes. The most common way is the natural ending of the trust on the life tenant’s death.
A flexible life interest trust will can also give trustees power to bring the interest to an end earlier.
Trustees can also end the interest early in favour of an individual, during the life tenant’s lifetime.
The life tenant is then usually treated as making a potentially exempt transfer.
That can save IHT if the life tenant then survives seven years, but it has its own tax consequences.
If the trust is still running two years after it was created, the trustees normally register it with HMRC’s Trust Registration Service.
Winding up correctly is a trustee decision, and complex cases are worth specialist tax advice.
What Are the Disadvantages of a Life Interest Trust?
A life interest trust will offers strong protection, but it is not the right fit for everyone.
- More complex than a basic will: there are more moving parts to set up and administer.
- Limited access for the survivor: the life tenant gets income or occupation, not the capital outright.
- Trustee duties: trustees must act in the beneficiaries’ best interests and usually decide unanimously.
- IHT is deferred, not removed: the trust capital is taxed in the life tenant’s estate on the second death.
- Severance must be done correctly: if the joint tenancy is not severed, the trust may not apply to the home.
- Possible family friction: remaindermen and the life tenant can disagree over a sale or a move.
- Not a guaranteed care-fee shield: a local authority can challenge arrangements aimed at avoiding care costs.
For straightforward couples who simply want everything to pass to the survivor, a standard mirror will may be enough.
Frequently Asked Questions
What is a life-time interest trust in UK law?
It is a trust that gives one person (the life tenant) the right to use an asset or take its income for life, with the capital passing to your chosen beneficiaries afterwards.

What is a life interest trust will UK?
It is a will that creates a life interest trust on your death, usually over your share of the family home.
Your partner can live there for life, and your share is preserved for your children or other named beneficiaries.
What happens at the end of a life interest trust?
The protected capital passes to the remaindermen named in your will.
The trustees either transfer the asset to them or sell it and distribute the net proceeds, and the trust then closes.
How much is a life interest trust will?
Our Life Interest Trust Will Template is £60.00 as a one-time payment, with both Editor and Interview versions included.
The matching Notice of Severance of Joint Tenancy Template is £15.00, or both are available together as a bundle.
Do I need a solicitor?
Many people complete a straightforward life interest trust will without one, using clear guidance throughout.
Consider solicitor review if you have high financial stakes, a blended family, or complex circumstances.
The choice is yours.
Is a life interest trust will legally binding?
Yes. When completed and signed correctly, a will creates a recognised legal document under England & Wales law.
Our template includes a professional legal structure, the required trust provisions, and proper signing and witness requirements.
Can I set up a life interest trust will if I have a mortgage with my partner?
Yes. A mortgage does not stop you.
How you own the home and the loan secured on it are two separate things.
Most couples with a joint mortgage own as beneficial joint tenants, so your share would pass automatically to the co-owner on death.
Severing the joint tenancy changes only the ownership between you and your partner, turning it into tenants in common.
That gives you a defined share your will can place into the trust.
It does not need the lender’s consent, and it does not change who is liable for the mortgage.
You both remain responsible for the repayments, exactly as before.
The lender’s charge ranks ahead of the trust, so the trust protects your share of the equity, meaning the value left after the outstanding mortgage.
Many couples also hold life or mortgage cover that clears the loan on the first death, leaving the home unencumbered for the trust.
Bundle the Will With the Severance — and Save
A life interest trust will and a severance of joint tenancy work as a pair, so we offer them together.
Here’s why. A life interest trust will can only protect your share of the home if you own it as tenants in common.
But most couples own their home as joint tenants — where your share passes automatically to the co-owner on death.
That automatic transfer overrides your will, so the trust would never bind the property.
A Notice of Severance converts the joint tenancy into tenants in common, creating the share your will can then place in trust.

The Truth About “Free” Legal Template Sites (What You’re Really Signing Up For)
Most websites offering a “free legal template” follow the same pattern:
- You click because it’s advertised as free
- You spend 10–15 minutes answering questions
- At the very end, you must create an account or start a “free trial”
- Your card is required upfront
- The subscription auto-renews at £29–£39 per month
This isn’t a free template – it’s a subscription service. Many people only realise after being charged £300–£400 over the year.
Why These “Free” Templates Are a Legal Risk
- Outdated wording: not aligned with current UK law
- Missing mandatory clauses: required for legal validity
- No compliance guidance: leaving users without legal context
- No structured checklist: no way to verify the document works
- Not kept updated: often unchanged when legislation changes
One incorrect clause can weaken or invalidate the entire document.
Hidden Problem: Many “Free Template” Sites Aren’t Even UK-Based
Another major issue is that many free or auto-subscription template sites operate outside the UK and use documents originally drafted for the US legal system. These are then loosely adapted for “international use,” which creates serious problems:
- Incorrect terminology: taken from US contract law
- Missing UK statutory references: essential legal requirements omitted
- Non-applicable clauses: terms that don’t apply under UK legislation
- Legal conflicts: risks breaching UK consumer, employment, or GDPR rules
Why Templates UK Does the Opposite
- Drafted by UK professionals: written by experienced business & legal experts
- UK-law only: no US crossover or generic “international” templates
