An unmarried couple’s jointly owned home: Jones v Kernott explained
Joint names provide an important starting point, but Jones v Kernott shows why the parties’ intentions and later dealings may also matter.
After separation, “we bought it together” and “I paid for it alone afterwards” may both be true. The documents and the longer history help explain what each statement means for a property dispute.
Jurisdiction discussed: England and Wales. Case: Jones v Kernott [2011] UKSC 53. Judgment date: 9 November 2011.
What happened and what the Court decided
The couple bought their home in joint names without an express declaration of their beneficial shares. After separation, their financial arrangements changed. The Supreme Court restored the county court’s order giving Ms Jones ninety per cent and Mr Kernott ten per cent. The judgments examined the starting presumption of joint beneficial ownership and how changed common intentions could be identified or, in the relevant circumstances, shares assessed.
What the decision does not settle
Ninety-to-ten is not a formula for other separating couples. Sole-name property and an express declaration of shares can raise different issues. Nor is this simply a rule that every later mortgage payment changes ownership by the same amount. The whole relevant history must be considered.
Preparing for a consultation
- Obtain the transfer, any declaration of trust, mortgage documents and purchase records.
- Build a timeline of occupation, separation, payments and significant property decisions.
- Keep evidence of discussions about ownership and distinguish them from discussions only about day-to-day bills.
