What Happens to the House When an Unmarried Couple Splits Up?
Unmarried couples do not have the same property rights as married couples on separation. The outcome depends on legal ownership, contributions, and any formal agreements.
Quick Answer
When an unmarried couple splits up, there is no automatic right to a share of the partner's property in the way that exists on divorce. Rights depend on: whose name is on the legal title; whether there is a declaration of trust specifying shares; and whether a constructive or resulting trust can be established based on contributions and common intention. The law in this area is complex and advice is essential.
Full Explanation
Unlike married couples, who have comprehensive rights under the Matrimonial Causes Act 1973 to apply for financial orders on divorce, cohabiting couples in England and Wales have no equivalent 'cohabitation' legislation. This means that when an unmarried couple separates, property rights are determined by the general law of property, trusts, and contract — not by any concept of fairness or contribution to the relationship.
If the property is in one person's sole name, the starting point is that it belongs entirely to them. To claim a share, the other partner must establish a beneficial interest through one of the following routes: (a) an express declaration of trust — for example, a TR1 form (Land Registry transfer) that specifies shares — which is conclusive evidence of the agreed shares; (b) a resulting trust — where the partner contributed to the purchase price (deposit or mortgage) and the court infers a share proportional to that contribution; (c) a constructive trust — where both parties had a common intention (express or inferred) that both should have a beneficial interest, and the claiming party acted to their detriment in reliance on that common intention (Stack v Dowden [2007]; Jones v Kernott [2011]).
Establishing a constructive trust requires the court to infer the parties' intentions from all the conduct and circumstances of the relationship: paying the mortgage, making home improvements, making other financial contributions while the partner paid the mortgage, giving up a career, and similar factors. This is a fact-sensitive exercise and the outcome is uncertain.
If the property is held in joint names as beneficial joint tenants, both parties are presumed to own equal shares. If held as tenants in common, the shares are as stated in any declaration of trust or, if none, as the court determines on the Stack v Dowden/Jones v Kernott analysis.
Cohabiting partners who have contributed to a property can bring a claim under the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA), asking the court to determine their beneficial interest and, if appropriate, order a sale. These proceedings are brought in the county court or Chancery Division.
Legal Basis
- §Trusts of Land and Appointment of Trustees Act 1996 (TOLATA)
- §Stack v Dowden [2007] UKHL 17 (common intention constructive trust)
- §Jones v Kernott [2011] UKSC 53
- §Land Registration Act 2002 (express trusts and registered interests)
What To Do
Check the Legal Title
Obtain the Land Registry title for the property. This will show who is the registered legal owner(s) and, if there is a TR1 or deed of trust, what the declared beneficial shares are. Register a copy with the Land Registry's title if you have a deed of trust.
Locate Any Declaration of Trust
Search for any written agreement between you and your former partner about ownership shares — this could be a deed of trust, a cohabitation agreement, or even a TR1 with box 10 completed. If this exists, it is usually conclusive.
Instruct a Property Law Solicitor
Seek specialist legal advice. A solicitor can assess whether you have a claim to a beneficial interest and advise on the strength of any constructive trust argument based on your specific contributions and circumstances.
Attempt Negotiation and Mediation
Before court proceedings, consider mediating or negotiating directly with your former partner. Agreeing a share and formalising it avoids the uncertainty and cost of litigation.
Issue a TOLATA Claim if Necessary
If agreement cannot be reached, issue a claim under TOLATA asking the court to: declare your beneficial interest; order an account of the property's occupation; or order a sale and division of proceeds.
Important Warnings
Common law marriage does not exist in England and Wales — you have no automatic property rights simply because you have lived together for a long period.
Contributing to household expenses does not generally establish a beneficial interest in property — the contribution must relate directly to the property or be part of a course of dealing in which property was concerned.
Bringing a TOLATA claim is expensive and the outcome is uncertain — litigation should be a last resort.
