For many couples in England and Wales, living together feels no different to being married. Shared homes, shared finances, children, businesses, and long-term commitments often create the assumption that the law will treat cohabiting partners in much the same way as spouses. In reality, the legal position is very different.
Despite the enduring myth of the “common law marriage”, cohabitation does not create automatic legal rights or protections. From property ownership and pensions to inheritance and financial support after separation, the distinction between marriage and cohabitation can have significant legal and financial consequences, particularly where substantial assets, businesses, or family wealth are involved.
Understanding those differences is essential before making major life decisions together. In this article, we explore how the law treats married and cohabiting couples differently, the risks couples often overlook, and the practical steps that can help protect both parties in the future.
What are the key legal differences between cohabitation and marriage in England and Wales?
Marriage is a legally recognised status that gives spouses automatic rights and responsibilities. Cohabitation has no special legal status, therefore, in the eyes of the law, you remain two separate individuals.
Why do many couples misunderstand their rights when living together?
Many believe in the myth of the ‘common law marriage’, which suggests long term cohabitation offers ‘spouse like’ rights. It doesn’t and no such status exists in our legal system.
What legal protections does marriage provide that cohabiting couples do not automatically have?
On divorce, the Court can order maintenance, lump sums, and the transfer of property between spouses. If a spouse dies without a will, the survivor inherits automatically under the intestacy rules. Spouses can also share pensions on divorce and may receive survivor benefits. Cohabitants get none of these protections automatically.
Can marriage provide stronger protection for pensions and savings?
The Court is able to split pensions on divorce. There is no equivalent power for cohabitants. Savings and investments held in one partner’s sole name remain theirs alone if you only cohabit. After divorce, financial outcomes aim to be fair, which typically means the necessary sharing of such investments and savings. The same cannot be said for separation between cohabitants.
How do tax rules differ in relation to inheritance and asset transfers?
Spouses can transfer assets between themselves with no Capital Gains Tax or Inheritance Tax. A spouse can inherit any amount tax free, cohabitants cannot and may, therefore, face Inheritance Tax on figures above £325,000. Married couples are able to use the Marriage Allowance to share part of a personal tax allowance. Cohabiting partners are taxed as strangers.
What risks do cohabiting partners face if there is no formal agreement in place?
One partner can walk away with very little, even after years of contributing to the home and/or family. Disputes about who owns what can be slow and expensive and any legal claim has to be built from scratch, with the outcome being extremely uncertain.
What risks arise when property is held in one partner’s name?
The ‘non owner’ has no automatic share. They must demonstrate to the Court, that the law should treat them as a co-owner. This typically involves a claim under the 1996 TOLATA Act, which is unnecessarily technical and costly. If the claim fails, that partner may receive nothing despite years of contributions in the form of mortgage or bill payments.
How are business assets and shareholdings treated differently for married and cohabiting couples?
On divorce, the Court can divide a business or shares between both parties, even if owned by only one spouse. Cohabitants have no automatic right to share in a partner’s business, however much they helped. Any claim has to be built on trust principles, which is typically difficult to prove.
What Happens If a Relationship Breaks Down?
How are property, assets, and finances treated differently if a cohabiting relationship breaks down?
When dealing with a divorcing couple, the Court divides assets fairly under the Matrimonial Causes Act 1973. On the breakdown of a cohabitating couple, each person broadly keeps what is in their own name. Property is dealt with under strict trust and property law, not on the basis of fairness.
How do courts handle disputes between cohabiting couples compared to married couples?
In divorce cases, judges have wide discretion to do what is deemed fair, taking into account needs and contributions. In cohabitation cases, judges are limited to working out who legally owns what. Future needs, and non-financial contributions carry little to no weight.
What Financial Claims Can Cohabiting Partners Make?
How does the law approach financial provision and claims for cohabiting partners, particularly where children are involved?
There is no claim for ‘spouse style’ maintenance for the adult cohabiting partner upon separation. Regarding children, support is dealt with by the Child Maintenance Service, as it is for divorced couples.
What claims can be made under Schedule 1 of the Children Act, and what are the limitations?
A parent can ask for housing, a lump sum, or maintenance, but only for the child’s benefit. A home provided via Schedule 1 of the Children Act usually returns to the paying parent when the child finishes education.
In what situations can a cohabiting partner bring a claim against the other?
As stated above, property claims will be navigated via the 1996 TOLATA Act, only if a partner can show a beneficial interest in the home. Again, as seen above, child related claims will be pursued via Schedule 1 Children Act 1989, for the child’s benefit only. On death, a inheritance claim may be made under the Inheritance (provision for Family and Dependants) Act 1975.
What Happens on Death?
What happens on death? How do inheritance rights differ between married couples and cohabiting partners?
A surviving spouse inherits automatically under the intestacy rules, where there is no will stating otherwise. On the other hand, a surviving cohabitant inherits nothing automatically. An application may be made under the 1975 Inheritance Act, however, this outcome is not guaranteed. Therefore, a properly drafted will is essential for any cohabiting couple.
How Can Cohabiting Couples Protect Themselves?
How can a cohabitation agreement alter the legal position and reduce uncertainty?
A cohabitation agreement records how property, bills and finances are handled both presently and, in the future, if you were to separate. It sets out each person’s share in the home and contributions to it. Properly drafted, with independent legal advice, a cohabitation agreement is generally enforceable as a contract.
How do cohabitation agreements compare to pre-nuptial and post-nuptial agreements?
Cohabitation agreements are private contracts and generally binding when properly made. Pre and Post nuptial agreements are not strictly binding, but the Court will give them ‘real weight’ after Radmacher v Granatino (2010).
When Should You Take Legal Advice?
There are many different events throughout life that warrant seeking legal advice when living together. These include, but are not limited to:
- Buying a home together, or one partner moving into the other’s existing home
- Having a child or planning to start a family
- One partner giving up work or relocating their job for the relationship
- Receiving an inheritance
- Starting a business
- Or any other major change in finances

Many couples are surprised to discover that years of living together, contributing financially, or raising children does not automatically provide the same protections afforded to married spouses.
For couples with property, investments, businesses, inherited wealth, or children, taking advice early can help avoid uncertainty, costly disputes, and unintended financial consequences later on. Whether through a cohabitation agreement, declaration of trust, will, or pre- or post-nuptial agreement, proactive legal planning can provide clarity and reassurance for both parties.
