Thinking about putting your home into a Lifetime Trust

The Hidden Pitfalls

Putting your home into a lifetime trust has become a popular estate‑planning trend, often sold as a simple fix for inheritance tax, care‑fee protection, or avoiding probate. But lifetime trusts,  especially those involving your main residence,  sit at the intersection of tax law, trust law, and local authority rules, and the risks are far greater than most people realise.

Lifetime trusts are complex, and for most families, they don’t work the way they’re advertised.  Lifetime trusts are different to a trust created by a Will.  This article concerns lifetime trusts (i.e. where a trust is created by you in your lifetime and ownership of your home is given to that trust).

Here are the pitfalls people rarely get told about:

Gift With Reservation of Benefit — the trap that catches most people

If you put your house into a trust but continue living in it rent‑free, HMRC will almost always treat it as a gift with reservation of benefit (GWROB).

Meaning: 

For inheritance tax purposes, the house is treated as if you never gave it away at all.

Consequences:

• The full value of the property is dragged back into your estate on death

• Any “seven‑year clock” for a PET never starts

To avoid a GWROB, you must pay full market rent to the trust for the whole of your occupation period — which most people don’t want to do.

Deprivation of Assets — local authorities can ignore the trust entirely

Many people are sold lifetime trusts as a way to “protect the house from care fees”. Local authorities are wise to this.

If the primary motive was to avoid care costs, the council can treat you as still owning the property, even if it sits in a trust.

This can happen years after the transfer.

Result:

• The trust is disregarded

• The house is counted in the financial assessment

• You gain no protection at all

Loss of Control — trustees, not you, own the house

Once the property is in trust, you no longer own it. The trustees do.

This means:

• You cannot sell the house without trustee consent

• You cannot re-mortgage it (including equity release)

• You cannot change beneficiaries without the trust deed allowing it

• Trustees must act unanimously unless the deed says otherwise

If relationships sour, you may find yourself living in a home you no longer control.

Unexpected Tax Charges — especially for discretionary trusts

Many lifetime trusts are drafted as discretionary trusts, which fall into the “relevant property regime” for taxation purposes.

This can trigger:

• Immediate 20% lifetime IHT charge if the gift exceeds the nil‑rate band (currently £325,000)

• 10‑year anniversary charges (up to 6%)

• Exit charges when assets leave the trust

People are often shocked to discover that “protecting the house” can create new tax bills that never existed before.

Capital Gains Tax — no principal residence relief on sale.

When you transfer your home into a trust during your lifetime, you are making a disposal for CGT purposes.

If the property is your main residence, you may get principal residence relief — but if it has ever been let out, used for business or owned jointly with someone who didn’t live there, you may face a CGT bill on day one.

If the trust later sells the property, the trust does not get full principal residence relief, unless the life tenant occupies it.

Mortgage and Lender Restrictions

If the property has a mortgage, you cannot simply put it into a trust.

You need lender consent — and most lenders refuse.

Even if the mortgage is small, the lender may:

• Demand repayment

• Revalue the property

• Change the product

This alone stops many trust plans in their tracks.

Loss of RNRB — the residence nil‑rate band can disappear

The Residence Nil‑Rate Band (RNRB) only applies when a home passes to direct descendants.

If the property sits in a discretionary trust at death, the RNRB may be lost entirely.

This can cost a family up to £140,000 in additional inheritance tax.

Professional Fees and Complexity

Lifetime trusts require ongoing administration:

• Annual tax returns

• Trustee meetings

• Legal advice

• Potential valuations

• Compliance with trust registration (HMRC Trust Registration Service)

Many people are sold a trust without being told they may face decades of ongoing costs.

It Often Doesn’t Achieve the Goal

The biggest pitfall is simple:

Most lifetime trusts do not achieve the purpose they were sold for.

They rarely:

• Save inheritance tax

• Protect against care fees

• Simplify probate

• Reduce risk

In many cases, they create more tax, more admin, and more risk than doing nothing.

When a Lifetime Trust Can Work

Lifetime trusts can be useful, but only in very specific situations and with the right legal advice. For example:

• A vulnerable beneficiary needs long‑term protection

• A blended family requires careful structuring

• A life interest trust is needed for remarriage planning

• There is a genuine asset‑protection need (e.g., business risk)

• The client is willing to pay rent to avoid GWROB

If you are considering a lifetime trust, make sure you get proper advice first from a regulated and experienced adviser. Be very wary of advice found on the internet or generated by AI.  For most people, a well-drafted Will Trust gives the protection they actually need, without the complications.
