Cohabitation and separation: your rights across the UK and Ireland

But despite this social shift, the legal recognition and protection afforded to cohabitants vary markedly between jurisdictions. 

The law does not treat cohabiting couples the same as married couples when they separate, and their rights depend heavily on where they live. This article examines the differences in cohabitation law upon the breakdown of the relationship, highlighting key distinctions in rights, remedies, and legislative frameworks, in the jurisdictions of:

• England and Wales
• Scotland
• Northern Ireland
• Republic of Ireland.

England and Wales 

The concept of a “common law marriage” is a legal myth in England and Wales. Living together, even for many years, does not automatically give a cohabitant rights to their partner’s property or financial support. 

What happens if you separate in England or Wales? 

Disputes are usually resolved through property law under The Trusts of Land and Appointment of Trustees Act 1996, not family law. Financial claims can be made if one can show: 

1. They contributed financially to a property, or
2. There was a shared intention that they would have a financial interest in the property. 

These claims can be complex, expensive, and uncertain. There is no ability to pursue wider financial claims (such as pensions or general capital adjustment), unlike in divorce proceedings

Cohabitants cannot claim maintenance from their partner unless there are children of the relationship. If they do have children, the cohabitant may be able to seek financial provision for the children, but this is for the child’s benefit, not the parent. 

Northern Ireland 

Northern Ireland largely follows the same approach as England and Wales – there are no automatic rights for cohabitants.

What happens if you separate in Northern Ireland? 

A cohabitant must rely on property ownership principles and provide evidence of financial contributions or agreements.

There is no automatic right to financial support. There are limited remedies unless there are children of the relationship.

Scotland 

Scotland provides more protection for cohabitants than any other part of the United Kingdom. This is following the Family Law (Scotland) Act 2006 bringing in a statutory regime. 

What happens if you separate in Scotland? 

A cohabitant may be able to apply to the court for financial provision if:

1.  Their ex-partner has derived economic advantage from contributions made by them during the course of the relationship, and;
2. Whether (and, if so, to what extent) they have suffered economic disadvantage in the interests of the ex-partner or any relevant child. 

The court can also make a repayment of such amount as it sees fit in order to recognise the economic burden of caring for a child of the relationship after the cohabitation ends.

However, claims must be strictly made within one year from the date of separation. The outcome is not guaranteed, and depends on fairness and evidence which will always vary from case to case.

Republic of Ireland 

Ireland provides a statutory scheme for cohabitants under the Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010 – but not all couples are covered. 

A cohabitant must satisfy the requirements to become what is known as a “qualified cohabitant” whereby the cohabitants must have lived together for: 

1. Two years if there are children of the relationship, or
2. Five years if there are no children of the relationship. 

What happens if you separate in the Republic of Ireland? 

Cohabitants may apply for: 

• Financial support (maintenance)
• Property adjustment orders (transfer or sale of a property); and
• Pension sharing. 

However, cohabitants must show they were financially dependent, and that the relationship caused that dependence.

Summary

Practical advice 

Due to their statutory frameworks, it can be seen that Ireland – and to a lesser extent Scotland – provide some protection and clarity for cohabitants as to their financial claims in the event of relationship breakdown. On the other hand, England & Wales and Northern Ireland provide very little protection, relying heavily on property and trust law, resulting in piecemeal and less predictable outcomes.

The breakdown of a cohabiting relationship can often be a very difficult time. One must only look at the music industry to see that it is founded on heartache. Certainty surrounding financial claims can at least ease some of this distress and any financial worries. 

The best protective measure cohabiting couples can take is to enter into a Cohabitation Agreement which can reflect how financial affairs will be managed during the relationship and what will happen should the relationship later breakdown (akin to a Pre-Nuptial Agreement for married couples), or Separation Agreement if the relationship has already broken down. Early advice is recommended, particularly for those based in Scotland due to the time limitations with respect to raising court proceedings in order to protect the ability to make a claim under the relevant legislation. 

The future 

To differing extents, the law in relation to cohabitation is deficient in each jurisdiction.

England & Wales has been considering reform as far back as the Law Commission’s recommendations in 2007, and now appears to be making more sure-footed attempts to remedy this. 

The British government published it consultation paper, A Fairer End to Relationships', on 5 June 2026 – the consultation will run until 14 August 2026 – which includes proposed reforms for cohabitants on separation. This recommends a statutory framework for cohabitants who have been living together for three years or if there is a child and that consideration be given to a cohabitant’s financial needs as result of the relationship breakdown (albeit a more narrowed interpretation than married couples). Legislative changes are expected but the timeframes for this are currently undetermined.

The Northern Ireland Law Commission has not commented on proposed reform for some time as it has been non-operational since 2015. However, it may be that Northern Ireland will keep a close eye on any legislative changes made in England & Wales and then consider whether any similar changes should be made in its own jurisdiction. 

The Scottish Government consulted on the potential reform of various aspects of family law in Scotland, and this consultation paper closed on 21 April 2026. Part 1 of the consultation was looking at improving cohabitants’ financial rights under the Family Law (Scotland) Act 2006. Much like in England & Wales, change is expected but the timeframe is unknown.  

Ireland already has a statutory scheme, but it is narrow in scope. Reform is focused on making that scheme work more effectively and shifting away from strict financial dependency towards broader fairness. However, no legislative changes are likely in the near future. Reform is also complicated by constitutional restrictions not applicable in the UK.
