GUIDE • DIVORCE & SEPARATION
Separation agreements
Not every couple who separates is ready to divorce, whether for personal, religious or financial reasons, or simply because it is too soon. A separation agreement allows couples to record how they will arrange their finances and family life while they live apart, providing clarity and stability during an uncertain period. This guide explains what a separation agreement is, how much weight it carries, and what happens to it if you later divorce.

KEY POINTS
- A separation agreement is a written contract setting out arrangements while a couple lives apart.
- It is not automatically binding in the same way as a court order, but the court will usually give it significant weight.
- Independent legal advice and full financial disclosure are essential to its strength.
- On divorce, its terms can be turned into a legally binding consent order.
- Arrangements for children can always be revisited if they are no longer in the children's best interests.
What is a separation agreement?
A separation agreement is a written agreement between spouses or civil partners who have decided to live apart. It is usually prepared as a deed and sets out how money, property and arrangements for any children will be dealt with during the separation. Some couples use it as a stepping stone towards divorce, while others remain separated long term without ever divorcing.
Is a separation agreement legally binding?
Not in the same way as a court order. A separation agreement cannot prevent either party from later asking the court to decide the finances. However, the court takes a strongly pro-agreement approach. In Edgar v Edgar [1980], the Court of Appeal held that a formal agreement, properly and fairly arrived at with competent legal advice, should not be set aside without good and substantial grounds. In practice, a well-prepared agreement is likely to be upheld.
What can a separation agreement cover?
A separation agreement can address most practical and financial matters, including:
• who will live in the family home, and who will pay the mortgage, rent and bills;
• how savings, investments and other assets will be divided;
• responsibility for debts;
• maintenance for either spouse;
• child maintenance and arrangements for where the children will live and spend time; and
• how the arrangements will be reflected in any future divorce.
How can we make sure the court will uphold it?
The court will look closely at how the agreement was made. It is far more likely to be upheld where each party took independent legal advice, both gave full and honest financial disclosure, neither was put under pressure to sign, and the terms were fair at the time. An agreement made without advice, or where one party concealed assets, is much more vulnerable to challenge. Including a review clause, for example on a significant change in circumstances, can also help keep it fair over time.
What happens to the agreement if we later divorce?
If you decide to divorce, the terms of your separation agreement can be used as the basis for a consent order. Once approved by the court, the consent order is legally binding and enforceable, and it can achieve outcomes that an agreement alone cannot, such as a clean break or a pension sharing order. Until a consent order is made, financial claims between you remain open.
How is a separation agreement different from judicial separation?
Judicial separation is a formal court process that recognises a couple is separated without ending the marriage. Unlike a separation agreement, it allows the court to make most financial orders. It is sometimes chosen by couples who have religious objections to divorce, or who have been married for less than a year. For most couples, however, a separation agreement is a quicker and more private option.
Common questions
Usually not, because the divorce itself is dealt with on paper and most financial and children matters are settled without a contested hearing. Mediation, collaborative law, arbitration and solicitor negotiation can all help you reach an agreement without going to court.
You can apply for the conditional order after a minimum of 20 weeks, and then for the final order six weeks and a day after that, so around seven months at the earliest. It often takes longer, especially if you wait for finances to be agreed before applying for the final order.

How we work
An experienced family solicitor will run your matter from the first meeting onwards, and you will deal with them directly rather than being passed between members of a team.
Part of their job is to help you decide where your time and money are best spent. In most divorces there are points worth pressing and points that make little difference to the end result, and we will be straightforward with you about which is which.
A lot of matters are resolved through negotiation or mediation, and where that is realistic we will recommend it. Where it is not, because the other side will not engage, or disclosure is incomplete, or the issues are genuinely contested, we will advise you on taking the matter to court and act for you there.
Rushton Family Law is the sister brand of Vardags. If your case involves complex finances or international issues, we will introduce you to the Vardags team.
