Learn how jointly owned property affects challenges to a will in England and Wales. This detailed guide explains joint tenancy and tenancy in common, legal grounds for contesting a will, procedural steps, time limits, and practical considerations for co‑owned property disputes.
Disputes over wills can become particularly complex when the deceased person owned property jointly with others. Whether you are a beneficiary, a family member, a co‑owner, or simply seeking to understand your rights, jointly owned property raises distinct legal issues in contested probate. This guide explains how jointly owned property is treated under English and Welsh law, the ways in which ownership affects a will challenge, the legal grounds on which you might bring a claim, and the practical steps involved. It is designed to be accessible to the public while remaining accurate and relevant for solicitors and students.
Understanding Joint Ownership of Property
When property is owned by two or more people in England and Wales, the form of ownership significantly affects what happens when one owner dies. There are two main legal forms of co‑ownership: joint tenancy and tenancy in common.
1. Joint Tenancy
Under a joint tenancy, all owners own the whole property together, without defined shares. When one owner dies, their interest in the property passes automatically to the surviving co‑owner(s) by law through the right of survivorship. This occurs irrespective of the terms of the deceased owner's will.
2. Tenants in Common
Under a tenancy in common, each owner holds a distinct share in the property (for example, 50/50 or another agreed proportion). A co‑owner's share forms part of their estate on death and can be passed on according to their will or under intestacy rules if there is no valid will.
The choice between these forms of ownership is typically made when the property is purchased. Where no choice is recorded, joint tenancy may be presumed, and severance can be used to convert joint tenancy into tenancy in common, giving each owner a share that can be inherited.
How Joint Property Affects a Will
The way property is owned can determine whether the deceased's will has any effect on that property.
Joint Tenancy: Survivorship Overrides the Will
If property is held as joint tenants, the deceased's interest automatically passes to the surviving joint owner through the right of survivorship. This occurs by operation of law and cannot be altered by the terms of a will. As a result:
- The deceased's will cannot control the disposition of the property.
- The property does not form part of the deceased's estate for distribution under the will.
- Beneficiaries named in the will may receive nothing in respect of that property, even if the will specifies otherwise.
Tenancy in Common: Share Can Be Controlled by Will
Where property is held as tenants in common, each co‑owner's share forms part of their estate on death. This share can therefore be:
- Bequeathed to beneficiaries under the will.
- Distributed under the rules of intestacy if there is no valid will.
- Included in claims against the estate under the Inheritance (Provision for Family and Dependants) Act 1975, wholly or in part.
How to Challenge a Will Where Joint Property Is Involved
Challenging a will involving jointly owned property depends on both the grounds of the claim and the nature of the ownership of the property in question.
1. Confirm the Form of Ownership
The first practical step is to check how the property was owned. This information is available from the Land Registry. If the property is held as joint tenants, then the share of the deceased will not form part of the estate at all, limiting the ability of the will to affect the asset.
2. Grounds for Challenging a Will
The legal grounds for challenging a will in England and Wales apply irrespective of the type of assets involved. Typical grounds include:
- Lack of testamentary capacity – the deceased did not have sufficient mental capacity when making the will.
- Undue influence – the deceased was improperly pressured or coerced.
- Invalid formalities – the will was not signed or witnessed correctly.
- Fraud or forgery – the will is not genuine.
- Failure to make reasonable financial provision under the Inheritance Act 1975, where eligible dependants believe the will does not provide adequately for them.
When joint property is involved, these challenges may be complicated by the fact that the property may not form part of the estate available for distribution if held as joint tenants.
3. Claims Under the Inheritance Act 1975
A common challenge to a will is a claim for reasonable financial provision under the Inheritance (Provision for Family and Dependants) Act 1975. Where a property was owned jointly as joint tenants, the deceased's share will have passed to the survivor and may not be part of the estate on which a claim can be based. The court has discretion to include the deceased's notional entitlement for the purposes of provision in limited circumstances, but the legal position is complex.
Practical Steps in a Dispute
Challenging a will that involves jointly owned property typically involves the following steps:
Step 1: Check the Land Registry
Obtain official documentation showing how the property was held at the date of death. This confirms whether the right of survivorship applies.
Step 2: Seek Legal Advice Early
Specialist contentious probate solicitors can review the circumstances, interpret the title documents, and explain your options for challenging the will.
Step 3: Lodge a Caveat if Necessary
If probate has not yet been granted, you can lodge a caveat at the Probate Registry to prevent the grant of probate while you prepare your claim. This can be crucial to preserving your position.
Step 4: Prepare Evidence
Prepare evidence supporting your claim, including medical records, witness statements, title deeds, and any relevant correspondence. For joint property disputes, formal evidence of ownership or severance will be central.
Step 5: Consider Alternative Dispute Resolution
Mediation or negotiation can sometimes resolve disputes without formal court proceedings, reducing time and cost.
Step 6: Issue Court Proceedings
If no resolution is reached, your solicitor may issue proceedings in the appropriate court to determine the validity of the will or to pursue a claim under the Inheritance Act.
Time Limits and Procedural Considerations
- Inheritance Act Claims: Generally must be started within six months of the grant of probate, although courts may allow late claims in exceptional circumstances.
- Contesting Validity: There is no strict time limit on challenging a will's validity, but delay can weaken evidence.
- Caveats: A caveat delays probate for up to six months and can be renewed by responding to a warning notice.
Common Questions
Can the terms of a will change what happens to joint property?
No. If property is held as joint tenants, the right of survivorship applies automatically and cannot be overridden by the will.
Can a co‑owner be forced to sell jointly owned property?
Yes. Under the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA), a co‑owner can apply to the court for an order for sale or to settle shares, although the court has broad discretion and may not always grant a sale order.
Can joint property be brought back into the estate for inheritance claims?
In limited Inheritance Act 1975 claims, the court may treat the deceased's notional entitlement as part of the estate to achieve reasonable financial provision, but such applications depend on specific circumstances and judicial discretion.
Key Takeaways
Challenging a will that involves jointly owned property in England and Wales hinges on understanding how the property was owned. Joint tenancy means the deceased's share passes automatically to the survivor by right of survivorship and generally falls outside the deceased's estate, limiting the impact of a will. Tenancy in common allows each co‑owner's share to form part of the estate and be dealt with by will. Legal challenges to wills may be based on lack of capacity, undue influence, invalid formalities, fraud, or failure to make reasonable financial provision under the Inheritance Act 1975. Practical steps include verifying title ownership, seeking specialist legal advice, lodging caveats, and preparing evidence. Time limits apply to claims under the Inheritance Act, and complex property disputes may require applications to the court under TOLATA.
