Joint Tenancy and Right of Survivorship UK: What It Means for Your Estate

Updated: 16 May 2026 • Reading time: 8 min

How you own property jointly has a profound effect on what happens when you die. The choice between joint tenancy and tenants in common determines whether your share passes automatically to the surviving owner — or whether it can be left in your will to whoever you choose. Many couples do not know which they have, or what the consequences are.

Joint Tenancy: The Right of Survivorship

When property is held as joint tenants, each owner holds the whole property together with the other(s). There are no separate quantified shares. On the death of one joint tenant, the right of survivorship (the Latin ius accrescendi) applies automatically: the deceased’s interest extinguishes and the surviving joint tenant(s) become the sole owner(s).

This happens by operation of law — immediately, without any need for probate in respect of the property. The deceased’s will has no effect on jointly-held property. Even if the will says “I leave my house to my children,” if the house is held as joint tenants the surviving spouse gets it instead.

Tenants in Common: Separate Shares

When property is held as tenants in common, each owner has a distinct quantifiable share. Shares can be equal (50/50) or unequal (e.g. 70/30 to reflect different contributions to the purchase). Each owner can deal with their share independently — they can sell it, mortgage it, or leave it in their will.

There is no right of survivorship between tenants in common. When a tenant in common dies, their share forms part of their estate and passes under their will (or the intestacy rules if there is no will).

How to Tell Which You Have

You can check the Land Registry title for your property (via the Gov.uk Land Registry portal, currently £3 per official copy). Look for a Form A restrictionon the title — wording along the lines of:

“No disposition by a sole proprietor of the registered estate (except a trust corporation) under which capital money arises is to be registered unless authorised by an order of the court.”

If this restriction is present, the property is held as tenants in common. If there is no such restriction, it is likely held as joint tenants — though the original transfer deed should also be checked.

Severing a Joint Tenancy

A joint tenancy can be severed unilaterally — meaning one co-owner can convert the ownership to tenants in common without the other’s consent, by serving a written notice of severance. The severance is immediate and effective on service of the notice. Key rules:

• The notice must be in writing but does not need to be in any prescribed form
• It must be served on all other joint tenants (posted to the property is generally sufficient)
• Once served, it cannot be withdrawn — the joint tenancy is severed immediately
• The Land Registry should be updated using Form RX1 to register a Form A restriction — this protects the severed position and puts third parties on notice

After severance, each co-owner holds an equal share (the severance does not redistribute shares; it converts the form of ownership). A declaration of trust should be prepared contemporaneously if the shares are to be unequal or if more complex beneficial interests are intended.

IHT Implications

Joint Tenancy: Spousal Exemption

Where jointly-owned property passes by survivorship to a surviving spouse or civil partner, the spousal exemption applies — no IHT on the first death. However, the full value of the property then sits in the survivor’s estate. On the second death, IHT is potentially payable on the combined estate (including the full property value) above the available nil-rate bands.

Tenants in Common: NRB Planning

Holding property as tenants in common allows each spouse’s share to pass under their will into a nil-rate band trust or protective property truston the first death. This uses the first spouse’s nil-rate band (£325,000) immediately, keeping that value out of the survivor’s estate. On the second death, only the survivor’s own estate (including their share of the property) is taxable. For larger estates, the savings can be significant.

Note: The transferable nil-rate band (where any unused NRB passes to the surviving spouse) has reduced the urgency of this planning for many couples, but tenants-in-common trusts remain valuable for second marriages, estates above the combined NRB + RNRB, and asset-protection planning.

When Tenants in Common Makes Sense

• Second marriages — protecting children from a first relationship
• Unmarried couples who want their share to pass to their own family
• IHT planning — using will trusts to reduce estate on second death
• Unequal contributions — clearly recording who paid what
• One owner has creditors or personal financial risk
