WhatsApp messages can decide who keeps the house after a break-up in the UK
Key Points
- WhatsApp chats can decide how separating unmarried couples split a home.
- Courts examine the whole course of dealing between partners.
- Casual messages can outweigh later witness statements in court.
- Courts can order iCloud and Google Drive WhatsApp backups.
- The government consulted on cohabitation reform in summer 2026.
More than 3.5 million unmarried couples in England and Wales may need ot consider WhatsApp chats when deciding who keeps their home.
This is according to legal firm Lester Aldridge which notes that disputes over jointly owned property between unmarried couples fall under the Trust of Land and Appointment of Trustees Act 1996, known as TOLATA.
Divorcing couples go through a separate regime under the Matrimonial Causes Act 1973, which gives judges wide discretion to divide assets.
Cohabiting couples have no equivalent protection, so courts must work out what both partners intended when they bought the property. Common law marriage does not exist in England and Wales, despite many people believing it does.
What courts look for
The House of Lords ruled in Stack v Dowden in 2007 that courts must consider the whole course of dealing between the couple.
The Supreme Court added in Jones v Kernott in 2011 that a couple’s intentions over ownership can change over time.
A string of WhatsApp messages sent across several years can therefore show how each partner’s view of their share shifted. The firm gave several examples of messages that could swing a case, including:
- “I paid the deposit but we agreed it’s 50/50”, which would likely support a claim for an equal share.
- “You can live there but it’s still my house”, which could undermine a partner’s claim to own part of the property.
- “I’ll cover the mortgage this month, you can pay me back”, which could point to a loan rather than a stake in the home.
The firm said a person’s credibility can suffer if their evidence in court contradicts what they wrote to their partner at the time.
Voice notes and video messages can also go before a judge, although lawyers must transcribe and authenticate them first.
Deleting messages may not help
Civil Procedure Rules require both parties to disclose relevant electronic documents, including full WhatsApp conversations and complete email chains. Each side must also confirm whether they deleted any messages and when they did so.
Courts can order a party to hand over WhatsApp backups stored on iCloud or Google Drive, so wiping chats from a phone does not remove the evidence.
Judges can also examine the data embedded in digital files to test claims that someone altered a screenshot or that another person sent the message.
Reform on the way
The government launched a consultation called A Fairer End to Relationships in June 2026, proposing new legal protections for cohabiting couples. The consultation closed on 14 August and covers England and Wales only, as family law is devolved.
Its proposals include extending intestacy rights to cohabitants whose partner dies without a will.
The government said any new regime for cohabitants will remain narrower than the rules for divorcing couples and will not apply equal sharing of assets.
Cohabitation is the fastest-growing family type in England and Wales.
