Clear and informative detail about prenuptial agreements and cohabitation. Find out what you can do in the event of disputes, and how Slater & Gordon can help.

Planning a future with your partner is an incredibly exciting period. Looking ahead to your shared life together with hopes of what it will bring is an experience many couples share when making big decisions together, whether that’s moving in with each other or choosing to get married.

It’s important to know what your rights are if you are deciding to live together, or if you have openly discussed prenups ahead of marriage. Here, we explain what prenups and cohabitation agreements are, and how Slater & Gordon can support.

What is a prenuptial agreement?

A prenuptial agreement (often called a prenup) is a contract made between two parties before they marry. A prenup specifies an agreed settlement with regards to property and other assets in the unfortunate event that your marriage breaks down.

While they are often regarded as simply a way for rich people to protect their assets when they marry someone less wealthy, that isn't the only purpose of a prenuptial agreement. In fact, a prenuptial agreement can be a good way to start your marriage in a spirit of openness and honesty. This is especially true if it is drawn up in such a way as to ensure that you would both be able to move on in your lives with financial security in the event of divorce.

What can be included in a prenuptial agreement?

A prenuptial agreement should include details of how any property or financial assets you and your partner own are split in the event of a divorce. An expert prenup solicitor can provide you with legal advice and guidance on what to include in your prenuptial agreement depending upon your personal circumstances, though common areas to include are:

  • Ownership of property, including any property each spouse brings into the marriage and what would happen to the family home in the event of a divorce
  • Money, including investments held separately, savings and money kept in joint accounts
  • Responsibility for any debts, including those incurred separately before the marriage and those during

Moving in with a partner is an exciting time, but if you aren’t married, you don’t have the same legal protection. A cohabitation agreement can be a good way of protecting your assets and safeguarding your future.

What is a cohabitation agreement? Sometimes called a ‘living together’ agreement, a cohabitation agreement is a legal document that sets out the rights and responsibilities of a couple who live together, the ownership of assets (including property), and what should happen if the relationship breakdowns later.

While it is a commonly held belief that living together, particularly if you’ve lived together for a while, makes you common law partners and gives you the same legal protection as married spouses or a couple in a civil partnership. However, this is not the case. The truth is that, without a legal agreement between the two of you, you don’t have any set legal rights regarding jointly owned assets.

Cohabitation agreements are a good way for couples who are not married or in a civil partnership to protect their rights and assets in the event of separation, and to define legally their responsibilities to one another.

What can a cohabitation agreement include?

A cohabitation agreement can cover a wide range of areas, though the exact content will depend upon your circumstances. It should set out who own which assets, either outright or as a proportion, and could cover things like:

  • what each person’s share of the mortgage or rent is
  • how the bills should be handled
  • how ownership of any property should be split
  • the ownership of any other assets, such as cars, furniture, and other high-value items
  • how other financial issues should be dealt with, including life insurance, pensions, bank accounts, and the payment of debts
  • ownership and responsibility of any pets
