Cohabitation Without Marriage: What the Law Does and Does Not Assume

Few legal phrases cause more confusion than 'common law marriage'. In England and Wales, the term has no legal meaning. A couple may live together for many years, share a home and raise children, but they do not acquire the automatic rights that flow from marriage or civil partnership. That does not mean cohabitants have no legal protection. It does mean that protection depends on ownership, agreements, wills and the general law rather than on the length of the relationship.

There Is No Common Law Marriage

Despite its frequent use in conversation, no statute or court doctrine creates a status of common law spouse. A couple who have lived together for two years and a couple who have lived together for twenty years are, in law, in a similar position unless they have made specific arrangements. The legal consequences of separation or death are not based on the durability of the relationship. They are based on legal ownership, contractual arrangements, parenthood and any will that has been made.

That message can be unwelcome, particularly where one partner has given up work, cared for children or contributed to a home that is held in the other partner's name. The law does not ignore those contributions, but it approaches them through property and family law rather than through a notional marriage.

What Happens on Separation

When an unmarried couple separate, neither partner has an automatic right to maintenance from the other, to a share of the other's pension, or to a share of the family home simply because of the relationship. The court is not asked to divide assets in the way it can on divorce. Instead, each person's rights depend on what they own and what they can establish.

If the home is in one partner's name, the other may still have a beneficial interest. That interest might arise from an express agreement, a common intention that the property was to be shared, or contributions to the purchase price, mortgage or substantial improvements. The court can determine such disputes under the Trusts of Land and Appointment of Trustees Act 1996, often called TOLATA. These cases are fact-sensitive. Evidence of discussions, financial contributions and the parties' conduct can matter a great deal. Paying household bills may be relevant in some circumstances, but it is rarely enough by itself to establish an interest in the property.

Property Ownership Matters More Than Intentions

Legal title is the starting point. If a home is owned by both partners as joint tenants, each owns the whole property jointly, and the right of survivorship applies on death. If they own as tenants in common, they hold distinct shares, which can be different sizes. On separation, the property may need to be sold or one party's share bought out.

Where only one partner is on the title, the other should take advice early. A declaration of trust can record the shares in which a property is held. It is far easier to put that in place when a property is bought or remortgaged than to reconstruct the position years later. Couples should not assume that contributing to a deposit, paying half the mortgage or funding a renovation will automatically translate into a half share. The paperwork needs to reflect the reality.

Wills, Intestacy and Pensions

If an unmarried partner dies without a will, the surviving partner has no automatic entitlement under the intestacy rules. The estate passes according to statute to spouses, civil partners, children and other relatives. A will can make provision for a partner, but it must be prepared properly and kept under review.

Pensions and life assurance need separate attention. Death benefits are often governed by scheme rules and nomination forms rather than by a will. A nomination made years ago may no longer reflect the couple's circumstances. In limited circumstances, a cohabitant may be able to apply for provision from an estate under the Inheritance (Provision for Family and Dependants) Act 1975. Such claims are costly and uncertain. They are not a substitute for a will.

Children and Financial Responsibilities

Parents have legal responsibilities towards their children whether or not they are married. Child maintenance is dealt with through the Child Maintenance Service or by agreement. An unmarried parent may also apply to the court under Schedule 1 to the Children Act 1989 for orders for the benefit of a child, such as a lump sum or property provision. Those claims are child-focused. They are not the same as a spouse's financial claim on divorce.

Parental responsibility is a separate issue. It concerns decisions about a child's upbringing, not the division of assets between adults. Unmarried parents should take advice on parental responsibility and on arrangements for children if the relationship ends.

Cohabitation Agreements

A cohabitation agreement records how a couple intend to deal with property and finances during the relationship and if they separate. It is not a marriage and it does not create marital rights. It is a contract, and if it is properly prepared it can carry legal weight. For that reason, both parties should receive legal advice before signing, should provide full financial disclosure, and should understand the terms they are agreeing to. Independent advice reduces the risk of the agreement being challenged later.

An agreement can deal with existing property, future purchases, contributions, savings and separation. It cannot determine a child's arrangements in a way that overrides the court's welfare jurisdiction. It should be reviewed when circumstances change, such as a house purchase, a new child, a career change or a significant inheritance.

Practical Steps for Couples

Couples should talk about money and property earlier than feels comfortable. Make a will. Review pension and life assurance nominations. Decide whether legal title reflects the true ownership of the home. Consider a declaration of trust or a cohabitation agreement. Keep records of significant financial contributions. Take advice before buying, moving or giving up work to care for children.

None of this is romantic, but it is practical. A clear arrangement made while a couple are together can prevent a bitter dispute later. Davis Solicitors can advise on wills, property ownership, cohabitation agreements and the legal position following separation.
