Severing a Joint Tenancy UK (2026): How to Change Joint Tenants to Tenants in Common

Joint tenants and tenants in common are the two ways in which two or more people can co-own property in England and Wales. The differences are fundamental: (1) JOINT TENANCY — THE RIGHT OF SURVIVORSHIP: when property is held as joint tenants, each owner does not have a distinct share that can be separated from the other. Instead, all joint tenants own the whole property together. The critical consequence is the RIGHT OF SURVIVORSHIP (jus accrescendi): on the death of one joint tenant, their interest automatically passes to the surviving joint tenant(s) — regardless of any will or intestacy. A deceased joint tenant CANNOT leave their share of the jointly owned property in their will; the will simply has no effect on the jointly owned interest; (2) TENANTS IN COMMON — DISTINCT SHARES: when property is held as tenants in common, each owner has a distinct, quantified SHARE in the property. The shares may be equal (50%/50%) or unequal (e.g. 70%/30%). Each tenant in common can: (a) leave their share by will to whoever they choose; (b) sell their share independently (though this is unusual in practice); (c) have the share taken into account in their estate for IHT and probate purposes; (3) WHY IT MATTERS: the default form of co-ownership for a married couple buying a property is usually JOINT TENANTS — which means the survivor automatically inherits the whole property. This prevents the first spouse from leaving their share to children or into a property trust. For estate planning (particularly IHT planning, care fee protection, or protecting children from a new relationship), the joint tenancy must be SEVERED to convert to tenants in common before a property will trust can take effect; (4) UNREGISTERED LAND: the same principles apply to unregistered land — but the evidence of tenancy in common is in the title deeds, not the Land Registry.

Severing a joint tenancy is a legal act that can be done UNILATERALLY by one co-owner without the consent of the other(s). The procedure under the Law of Property Act 1925 s.196 and Land Registration Act 2002 is as follows: (1) WRITTEN NOTICE OF SEVERANCE (LPA 1925 s.196): one joint tenant serves a written notice on the other joint tenant(s) stating that they wish to sever the joint tenancy. The notice: (a) must be in writing; (b) must be served on ALL other joint tenants; (c) must be communicated — effective on SERVICE, not on receipt (LPA 1925 s.196(3) — service at the last known place of abode or business in the UK is deemed good service); (d) does NOT need to be in any prescribed form — a letter stating 'I hereby sever the joint tenancy in [address]' is effective; (e) can be given by email or through the Land Registry process — though a formal written letter kept with the deeds is best practice; (2) MUTUAL AGREEMENT: if both co-owners agree to sever, they can sign a deed or a written agreement confirming the severance. A signed Form SEV (Restriction Form) submitted to HMLR achieves the same effect; (3) EFFECT OF NOTICE: once notice is served, the joint tenancy is immediately severed — the co-owners become tenants in common in equal shares (or in the proportions they held the joint tenancy). A joint tenancy of two owners converts to 50%/50% tenants in common on severance unless the parties have expressly agreed a different split; (4) LAND REGISTRY — FORM A RESTRICTION (OPTIONAL BUT STRONGLY RECOMMENDED): after severance, a FORM A RESTRICTION should be registered at HM Land Registry on the property's title. The Form A Restriction states: 'No disposition of the registered estate by a sole proprietor (not being a trust corporation) under which capital money arises is to be registered except under an order of the registrar or of the court'. This restriction: (a) prevents the surviving co-owner from selling the property as sole proprietor without appointing a second trustee to receive the purchase money; (b) protects the trust of land and the beneficial interests of the remaindermen. Without the Form A Restriction, the severance is legally effective but the Land Register still shows the co-owners as joint proprietors — which could mislead a buyer.

Yes — severance of a joint tenancy can be done UNILATERALLY, without the knowledge or consent of the other joint tenant. Under the Law of Property Act 1925 s.196, service of a notice of severance on the other party is sufficient. The other party does not need to consent, agree, or even be aware of the severance until the notice is served: (1) THE NOTICE REQUIREMENT: the notice must be served on the other joint tenants. 'Serving' means it must actually reach them (or be left at their last known place of abode or business). If the notice is destroyed before reaching the other party, it may not be effective — see Kinch v Bullard [1999] (wife posted notice of severance to matrimonial home; husband intercepted it when she tried to destroy it before delivery to prevent husband benefiting from severance — held: notice effective when it arrived through the letter box, before destruction); (2) EFFECT ON WILL: once the joint tenancy is severed, the severing party can leave their share by will. If they die before the will is updated to reflect the severance, the share will pass under the EXISTING WILL as a specific or residuary gift — or under intestacy if there is no will covering the share. It is essential to update the will immediately after severing; (3) MUTUAL WILLS COMPLICATION: if the co-owners have made mutual wills (binding wills that cannot be revoked after the first death), severance of the joint tenancy interacts with the mutual wills doctrine. Specialist advice should be taken where mutual wills are involved; (4) DIVORCE PROCEEDINGS: where property is owned as joint tenants and a marriage breaks down, each party should consider severing the joint tenancy promptly. Divorce does not automatically sever a joint tenancy — it is possible for a joint tenant to die during divorce proceedings with the joint tenancy still in place, causing the property to pass to the estranged spouse by survivorship.

Severing a joint tenancy has several tax implications: (1) IHT — NO IMMEDIATE IHT CHARGE ON SEVERANCE: severing a joint tenancy between co-owners does not itself create an IHT charge. The act of severance is not a transfer of value — it simply changes the form of co-ownership and makes the underlying beneficial interests explicit. No PET arises; (2) IHT PLANNING — ENABLING THE PROPERTY WILL TRUST: once severed, each co-owner can leave their share into a property will trust (life interest trust). The deceased's share passes into the trust — not to the surviving spouse absolutely. The spousal exemption (IHTA 1984 s.18) and RNRB (s.8D) still apply on the first death if the trust is an IPDI for the surviving spouse with remainder to children. See the property-trust-will-uk guide for full details; (3) CAPITAL GAINS TAX — PRINCIPAL PRIVATE RESIDENCE RELIEF: no CGT arises on severance itself — it is not a disposal. The property remains owned by the same parties in the same proportions; only the form of co-ownership changes. The principal private residence relief (PPR) position is unchanged; (4) STAMP DUTY LAND TAX — NOTHING TRIGGERED: SDLT is not triggered by the severance of a joint tenancy — no consideration changes hands. No SDLT return is required for the severance itself; (5) UNEQUAL SHARES — POTENTIAL GIFT: if the co-owners hold the joint tenancy in equal shares but agree on severance to hold as tenants in common in UNEQUAL shares (e.g. one party gets 70%), the rebalancing is a disposal for CGT purposes and a potential PET for IHT for the party giving up value. Legal advice is essential before agreeing to unequal shares; (6) TRUST OF LAND AND APPOINTMENT OF TRUSTEES ACT 1996 (TOLATA 1996): co-owned property is held on a trust of land under TOLATA 1996 regardless of whether the owners are joint tenants or tenants in common. The trustee obligations under TOLATA apply in both cases.

Special situations arise where severance is needed but one co-owner lacks capacity or has died: (1) CO-OWNER LACKS MENTAL CAPACITY: if one co-owner has lost mental capacity (e.g. due to dementia), they cannot consent to a severance or sign a notice themselves. In this situation: (a) if a PROPERTY AND FINANCIAL AFFAIRS LPA has been registered, the attorney(s) under the LPA can serve or accept a notice of severance on the incapacitated owner's behalf — acting in their best interests under MCA 2005; (b) if there is no LPA, a DEPUTY appointed by the Court of Protection can act — but a court order may be required if the deputy is not clear that severance is in the incapacitated person's best interests; (c) where no LPA or deputy exists, application to the Court of Protection under MCA 2005 s.16 for a specific order authorising severance may be necessary; (2) CO-OWNER HAS DIED: when one joint tenant dies, the right of survivorship operates IMMEDIATELY. There is no severance possible after death — the surviving joint tenant has automatically acquired the deceased's interest by survivorship. However, if the deceased sent a notice of severance but the notice was not received before death, the position depends on whether service was effective — see Williams & Glyn's Bank v Boland [1981] for equitable interests. A deed of variation of the deceased's estate (IHTA 1984 s.142) CANNOT include jointly owned property that has passed by survivorship — it was never part of the estate; (3) JOINT TENANCY WITH MORE THAN TWO OWNERS: if there are three or more joint tenants, one can sever their share without affecting the joint tenancy between the remaining owners. The severing party becomes a tenant in common in their share; the remaining owners remain joint tenants between themselves.
