Joint Property: Why Your Will May Not Control Your House

Here is the sentence that surprises more families than any other in estate administration: "the will doesn't apply to the house." Whether that is true depends on two words buried in your ownership paperwork — and most co-owners have no idea which two words apply to them.

The two ways to co-own property

• Joint tenants. You both own the whole thing together. When one dies, the property passes automatically to the survivor by "survivorship" — instantly, outside the will, outside probate. Most couples who bought together are joint tenants, often without remembering choosing it.
• Tenants in common. You each own a defined share (50/50 or any split). Your share is yours to leave by will, like any other asset. It does not pass automatically to your co-owner.

The same distinction applies to joint bank accounts, which generally pass by survivorship too.

Why it matters more than people think

Consider a second marriage where each partner has children from before. As joint tenants, when the husband dies the house becomes the wife's outright — and when she later dies, her will decides everything, whatever his said. His children can be disinherited by paperwork nobody read. As tenants in common, his half passes under his will — perhaps into a life interest trust letting his wife live there for life with his share preserved for his children. Same house, opposite outcomes.

Survivorship also has planning uses: for first-marriage couples with shared children, joint tenancy is often exactly right — simple, immediate, probate-free on the first death (see what probate costs).

How to check what you have — in minutes

Download your title register from HM Land Registry (a few pounds, online, instant). Look for the "Form A restriction" — words to the effect that no sole surviving owner can give a valid receipt for money. If that restriction is present, you are tenants in common; if absent, you are almost certainly joint tenants. Solicitors do this check at the start of every estate; doing it while you are both alive is when it is actually useful.

How to change it

Switching from joint tenants to tenants in common is a "severance" — a simple notice signed and served on the co-owner, plus a Land Registry form. No consent is needed: either owner can sever unilaterally, which is why it features in divorce checklists. Going the other way (to joint tenants) requires both owners to act together. Either change is cheap, and any conveyancer can do it — the expensive version is your family discovering the wrong answer after a death.

The estate-planning takeaway

Before assuming your will controls your biggest asset, verify how you own it. Blended family, unequal contributions, care-fee planning, or a wish to use trusts all point towards tenants in common with wills to match. Then keep will and ownership aligned when circumstances change — a will review that ignores the title register is only checking half the picture.

This is general information about the law in England and Wales, not personalised legal advice. Rules, thresholds and processes change, and Scotland and Northern Ireland have different rules in places — for anything that depends on your own circumstances, it is worth speaking to a solicitor (ideally one accredited by STEP or Solicitors for the Elderly) or checking GOV.UK and Citizens Advice for current detail.
