Notice of Severance UK: How to Sever a Joint Tenancy and Protect Your Share
Updated 31 May 2026 · 8 min read · Property & Co-Ownership
Most couples who buy a property together hold it as beneficial joint tenants — which means the right of survivorship applies and the surviving co-owner automatically inherits the whole property on the other’s death, regardless of the will. For many couples this is exactly right. But for those with children from previous relationships, or who simply want to control who inherits their share, severing the joint tenancy is a critical step — and it must be done during your lifetime, not in your will.
Joint Tenancy vs Tenancy in Common: The Key Difference
| Aspect | Beneficial joint tenancy | Tenancy in common (after severance) |
|---|---|---|
| Right of survivorship | Yes — survivor takes all | No — share passes by will/intestacy |
| Can leave share in will? | No — will is overridden by survivorship | Yes |
| Other co-owner’s consent needed to sever? | N/A | No — unilateral notice suffices |
| Effect on share of property value | Held undivided (always equal) | Fixed share (equal unless declaration says otherwise) |
The Critical Warning: You Cannot Sever in a Will
Common and costly misconception
A clause in a will saying “I sever the joint tenancy” is legally ineffective. The right of survivorship operates at the moment of death — before the will takes effect. By the time the will is read, the surviving co-owner has already taken the whole property by survivorship. Severance must be done during your lifetime by written notice to the other co-owner.
How to Serve a Notice of Severance
Under section 196(3)–(4) of the Law of Property Act 1925, a notice of severance must be:
- In writing — no prescribed form is required. The notice should clearly identify the property and state that the joint tenancy is being severed.
- Served on the other co-owner(s) — by leaving it at their last known place of abode or business, or by post to their last known address.
- Effective from delivery — left at the address, the notice is effective from the moment of leaving; posted, it is effective from when it would ordinarily arrive.
Practical steps: (1) Draft a notice of severance letter identifying the property and declaring severance. (2) Sign and date it. (3) Send by recorded delivery to the co-owner’s address and keep the proof of posting. (4) Keep a copy. (5) Apply to HM Land Registry to enter a Form A restriction to protect the severance on the register. (6) Update your will to leave your share to the intended beneficiaries.
What Share Do You Hold After Severance?
Where a joint tenancy is severed, the default position is that each co-owner holds an equal share of the beneficial interest — regardless of their financial contributions. If the parties agreed (expressly or by implication) on different shares, those shares will apply — but this must be evidenced by a declaration of trust or other written agreement. If you contributed 70% of the purchase price and want your share to reflect that, the severance alone does not achieve this — you need a declaration of trust that records the 70/30 split. This is why severance and a declaration of trust are best dealt with together.
After Severance: Update Your Will
Severing the joint tenancy means your share of the property is now transmissible — but it only passes as you intend if you have a valid will. Without a will, your share passes under the intestacy rules, which may or may not reach your intended beneficiaries. After serving a notice of severance, updating (or making) your will to expressly deal with your share of the property is essential. For couples in second marriages or blended families, a life interest trust in the will — giving the surviving partner the right to live in the property for life, with the underlying share passing to children on the second death — is the most common and effective structure.
Protecting the Severance at Land Registry
Severance of the beneficial joint tenancy does not appear automatically at HM Land Registry. To protect it: apply for a Form A restriction using Form RX1. The restriction prevents a sole surviving proprietor from selling or mortgaging the property alone — any disposition requires two trustees or a trust corporation, which protects the deceased co-owner’s estate. Without the restriction, a determined surviving co-owner (if also the sole registered proprietor) could in some circumstances deal with the property in ways that prejudice the estate’s beneficial share.
FAQs
What is a notice of severance and what does it do?
A notice of severance is a written notice given by one co-owner to the other(s) that converts the equitable joint tenancy into a tenancy in common. Once severed, the right of survivorship no longer applies — each co-owner holds a separate, transmissible share in the property that can be left by will or passes under the intestacy rules on their death. The notice of severance is effective from the moment it is received (or left at the co-owner's last known place of abode or business) under section 196 of the Law of Property Act 1925. It is a unilateral act — the other co-owner's consent is not required for the notice to be effective. Once served, severance cannot be unilaterally undone; only a mutual agreement to restore the joint tenancy (accompanied by a formal deed) can re-establish it.
How do you serve a notice of severance in England and Wales?
A notice of severance must meet the requirements of section 196(3)–(4) of the Law of Property Act 1925. Formalities: (1) The notice must be in writing — there is no prescribed form, but it should clearly state that the joint tenancy is being severed and identify the property. (2) It must be given to the other co-owner(s). Valid methods of service under s.196: (a) left at the co-owner's last known place of abode or business (effective from the date of leaving, not the date of receipt); (b) sent by post to the co-owner's last known address — effective from the time it would have been delivered in the ordinary course of post (not when actually received); (c) served personally. Practical steps: (1) Write a notice of severance letter for the property, signed and dated. (2) Send it by recorded delivery or hand-deliver it to the co-owner's address. (3) Keep a copy and record of service — the date and method of service. (4) Notify HM Land Registry by entering a Form A restriction on the title, which protects the severance in the register.
Does severance require the other co-owner's consent?
No. One of the most important features of the notice of severance is that it is a unilateral act — the co-owner who wants to sever can do so without the other's consent. The notice takes effect from the moment of service. The other co-owner does not need to agree, acknowledge the notice, or sign anything. In Kinch v Bullard [1998] 1 WLR 423, the High Court held that a notice of severance was effective from the time it was delivered through the letterbox, even though the recipient had retrieved the letter before reading it (in an attempt to prevent the severance). The practical consequence: if you are in a relationship breakdown and want to protect your share from passing to your partner on death, you can serve a notice of severance immediately — without negotiation. The other co-owner cannot prevent it. However, both parties should update their wills after severance to deal with the newly transmissible share.
What happens to the Land Registry title after severance?
Severance of the beneficial joint tenancy does not automatically appear in the HM Land Registry register — the legal title remains registered in the same names as before. To protect the severance and prevent any future dispute, the co-owner who has served the notice should apply to Land Registry to enter a Form A restriction on the title. A Form A restriction ('No disposition of the registered estate by a sole proprietor of the registered estate under which capital money arises is to be registered except under an order of the court') prevents a surviving co-owner from selling or mortgaging the property alone after the other's death, because it requires two trustees or a trust corporation to be involved. This protects the estate of the deceased co-owner — without the restriction, a sole surviving proprietor could (in limited circumstances) overreach the beneficial interests of the estate. To apply for a Form A restriction, complete Form RX1 and submit it to HM Land Registry with the appropriate fee.
Can you sever a joint tenancy in a will?
No. A will has no effect during the testator's lifetime — it only takes effect on death. But the right of survivorship operates automatically at the moment of death, before the will can take effect. This means that a clause in a will saying 'I sever the joint tenancy in the family home' is legally ineffective — the right of survivorship will have already operated before the will was read. To sever a joint tenancy, you must do it during your lifetime by serving a notice of severance on the co-owner(s). This is one of the most common and costly misunderstandings in estate planning — many people believe they have protected their share by addressing it in their will, when in fact the joint tenancy right of survivorship has already transferred the property to the survivor before the will could take effect.
Why would a couple in a second marriage sever their joint tenancy?
In a second marriage or blended family where both partners have children from previous relationships, holding as beneficial joint tenants creates a significant risk: if one partner dies first, the right of survivorship passes their entire beneficial interest to the survivor. The survivor's will then determines where the property goes on their death — and that may (or may not) include the first partner's children. If the survivor's will leaves everything to their own children, the first partner's children may receive nothing from the family home. Severing the joint tenancy — and holding as tenants in common, typically in equal shares or in the proportions contributed — allows each partner to leave their share to their own children in their will. Combined with a life interest trust in the will, the survivor can remain in the property for life while the underlying capital passes to each partner's own children on the second death. This structure (tenancy in common + life interest trust) is the standard estate planning approach for blended families.
