Protecting Your Family Home: Life Interest Trusts and Property Protection Trusts Explained

The Concern

For most people, their home is their most valuable asset and their most important legacy. The desire to ensure that the family home ultimately passes to your children — rather than being lost to a new partner, creditors, or care home fees — is one of the most common motivations for estate planning.

This concern is particularly acute for couples in second or subsequent marriages, homeowners who worry about the surviving partner remarrying, and families concerned about the potential impact of care home costs.

How Property is Normally Held

Before considering a trust, it is essential to understand how your property is owned. In England and Wales, jointly owned property can be held in one of two ways:

Joint tenancy. On the death of one owner, their share passes automatically to the surviving owner by right of survivorship. It does not pass under the will and cannot be placed into a trust on death.

Tenancy in common. Each owner holds a defined share of the property. On death, that share passes under the deceased's will and can be placed into a trust. This is the form of ownership required if you wish to use a trust to protect your share.

If your property is currently held as a joint tenancy, it may be necessary to "sever" the joint tenancy as part of the estate planning process. This is a straightforward procedure but must be done correctly.

The Life Interest Trust

A life interest trust is the most common trust-based tool for protecting the family home. On the first death, the deceased's share of the property passes into a trust. The surviving partner is named as the "life tenant" and has the right to live in the property for the rest of their life. On the surviving partner's death, the trust assets pass to the ultimate beneficiaries — typically the children.

This achieves several objectives simultaneously: the surviving partner has security of occupation for life, the deceased's share is ring-fenced against remarriage and other risks, the children are guaranteed their inheritance, and there may be inheritance tax benefits.

Property Protection Trusts

The term "property protection trust" is a marketing term rather than a strict legal category. Most commonly, it refers to a life interest trust specifically focused on the family home, usually established through a will. In some cases, it may refer to a discretionary trust that gives trustees broader powers.

Life Interest Trust vs Property Protection Trust

Life Interest Trust
  • Surviving partner has right to live in the property
  • Property passes to chosen beneficiaries on second death
  • Protects against sideways disinheritance
  • Created through a Will (takes effect on death)
  • Commonly used by married couples
Property Protection Trust
  • Broader asset protection beyond just housing
  • Can protect against creditors and divorce
  • May offer some care fee protection
  • Can be created during lifetime or in a Will
  • Often used alongside a Life Interest Trust

What About Care Home Fees?

This is perhaps the most sensitive and misunderstood area of estate planning. Local authorities have the legal power to treat a transfer of assets into a trust as a "deliberate deprivation of assets" if the transfer was made with the intention of avoiding care fees. If this finding is made, the authority can assess your finances as though the transfer had never taken place.

This does not mean trusts are never appropriate. But care fee avoidance should never be the primary motivation for establishing a trust. A trust established years before any care needs arise, for clear estate planning purposes, is in a much stronger position.

Practical Considerations

If you are considering a property protection trust, bear in mind: mortgage implications (lender consent may be required), stamp duty (transfers can trigger SDLT if there is outstanding mortgage debt), trust administration (including HMRC registration), and flexibility (can the surviving partner downsize?).
