A Domestic Partnership Agreement is a legally binding contract between two people in England and Wales who are living together in a committed relationship without being married or registered as civil partners. It sets out the couple's rights and responsibilities in relation to their financial affairs, property, household expenses, children, and other practical matters during the partnership and in the event of separation.

England and Wales do not recognise domestic partnerships as a formal legal status. Unlike civil partnerships (which are registered under the Civil Partnership Act 2004 and confer almost identical legal rights to marriage) or marriages, an informal domestic partnership carries no automatic statutory rights or protections. In particular, domestic partners in England and Wales have no automatic right to a share in the other partner's property, no automatic right to inherit on the other's death, and no right to apply for financial orders on separation equivalent to those available to divorcing couples under the Matrimonial Causes Act 1973.

Property disputes between cohabiting domestic partners in England and Wales are governed primarily by the general law of property and trusts, in particular the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA). TOLATA allows a partner with a beneficial interest in jointly occupied property to apply to the court for a declaration of their interest or for an order for sale. However, unlike the broad discretionary powers of the Family Court in divorce proceedings, a TOLATA application is determined by applying the law of trusts, which means the outcome depends on what was originally agreed or can be inferred from the parties' conduct, not on what a court considers fair in light of the parties' respective contributions and needs.

The Law Commission's 2007 report on cohabitation rights and the ongoing consultation on reform (launched by the government in 2025) reflect the acknowledged inadequacy of the current legal framework for domestic partners. Until statutory reform is enacted, a domestic partnership agreement remains the most important legal protection available to unmarried couples in England and Wales.

A domestic partnership agreement differs from a cohabitation agreement primarily in scope and emphasis. A cohabitation agreement focuses primarily on property ownership, housing arrangements, and separation provisions for couples who are sharing a home. A domestic partnership agreement typically provides a broader contractual framework covering the full range of the couple's shared financial life, including income, debts, insurance, financial support, and termination procedures, as well as property and housing matters.

A Domestic Partnership Agreement is advisable in a wide range of circumstances for couples in England or Wales who are living together or planning to live together without marrying or registering a civil partnership.

When the couple has significant combined assets, including owned property, savings, investments, or pension entitlements, a domestic partnership agreement provides a clear record of what each partner owns, how jointly acquired assets are to be shared, and what happens on separation. Without such an agreement, disputes about beneficial ownership can be expensive and uncertain.

When one partner contributes significantly more financially to the household or to the acquisition of property than the other, a domestic partnership agreement records the agreed arrangement and prevents the contributing partner's interest from being diluted by an implied equal-sharing presumption.

When one partner gives up work or reduces their hours to care for children or manage the household, a domestic partnership agreement can provide for financial recognition of that sacrifice, which would otherwise be legally unprotected under English law.

When either partner has children from a previous relationship, a domestic partnership agreement can record the agreed financial arrangements for those children and clarify which partner's assets are intended for their respective children, particularly in relation to inheritance.

When the couple wants to clarify the terms of their financial relationship before either party makes significant financial commitments or changes, such as buying a home together, starting a joint business, or one partner giving up employment to relocate, a domestic partnership agreement provides a clear contractual framework.

When either partner has significant pre-existing debts or liabilities, a domestic partnership agreement can protect the other partner from responsibility for those debts by expressly recording that they remain the debtor partner's sole obligation.

A well-drafted Domestic Partnership Agreement for use in England and Wales should address several key areas to provide meaningful legal protection and be enforceable as a contract.

The status clause must confirm that the agreement is intended to be legally binding and that the partners are not married or registered civil partners. It should record that each partner entered into the agreement freely and voluntarily, with the benefit of independent legal advice and on the basis of full financial disclosure.

The property and income division clause is the most important financial provision. It should clearly state whether income earned and property acquired during the partnership will be treated as jointly owned or kept separate. For couples who own or are buying property together, it should specify the beneficial ownership shares, consistent with any declaration of trust or Land Registry title entries.

The household expenses clause should specify how the partners will share day-to-day costs, including rent or mortgage payments, council tax, utilities, and groceries. A joint account arrangement for household expenses, with clear contribution obligations, helps to manage shared finances transparently.

The debt clause should state whether each partner is responsible for their own debts or whether household debts are shared. It should confirm that pre-existing debts remain the sole responsibility of the partner who incurred them.

The children clause, where applicable, should record agreed arrangements for childcare costs and financial support, while acknowledging that any provisions relating to children are subject to the overriding jurisdiction of the court under the Children Act 1989.

The termination clause should specify the notice period required before either partner can terminate the agreement, the procedure for division of assets on termination, and the dispute resolution method to be followed if the partners cannot agree. A mediation-first approach is recommended and demonstrates reasonableness to a court.

The inheritance clause should strongly encourage each partner to make a valid will, acknowledging that there is no automatic right to inherit under the intestacy rules and that, while the Inheritance (Provision for Family and Dependants) Act 1975 may offer some protection after two years of cohabitation, any such award is at the court's discretion.
