High-profile relationships often shine a spotlight on issues that many couples quietly face behind closed doors. The recent marriage of media personality Katie Price, reportedly just one week after meeting her partner, has sparked discussion about whirlwind romances and, more importantly, the legal and financial implications of marrying quickly.

While every relationship is unique, such rapid engagements highlight the reality that where is little time before a wedding, there is often no meaningful opportunity to seek legal advice or put financial protections in place. This is where prenuptial agreements can play a vital role.

What is a Prenuptial Agreement

A prenuptial agreement, often called a prenup, is a formal document agreed upon by a couple before marriage or civil partnership. It sets out how financial assets will be managed during the relationship and how they would be divided if the relationship were to end.

Prenuptial agreements are designed to:

  • Encourage open and honest discussions about finances before marriage, fostering trust and transparency,
  • Protect pre-marital assets or future inheritances, including family assets, businesses, or property acquired before the relationship,
  • Offer protection against being responsible for your spouse’s debts,
  • Provide financial security for children from previous relationships,
  • Avoid lengthy, stressful, and costly financial disputes if separation occurs.

While prenuptial agreements are not automatically legally binding in the UK, they are highly persuasive to the court provided certain safeguards are met. These include full financial disclosure by both parties, both parties seeking independent legal advice, the parties reaching a voluntary agreement, and signing the document at least 28 days before the wedding.

The Risk of Rushing: When there Simply isn’t Enough Time

In cases where couples marry very quickly, there may not be a realistic opportunity to reflect on financial arrangements, obtain independent advice, or ensure that any agreement would later be viewed as fair by the court. This can leave both parties exposed.

Additionally, any agreement entered into within the 28 days preceding the marriage or civil partnership will not be upheld, as it is unlikely all the safeguards for these agreements have been met. In those circumstances, a postnuptial agreement would also be beneficial.

Without a prenuptial agreement, financial matters on divorce are determined by the court, which has a wide discretion. This can lead to outcomes neither party anticipated, particularly where one person enters the marriage with significantly more assets, a business, or existing family responsibilities.

A thoughtfully prepared prenuptial agreement allows couples to retain control, rather than leaving decisions to be made later under emotional and financial strain.

Importantly, the earlier a prenuptial agreement is considered and prepared, the stronger and more effective it is likely to be. Allowing more time for open discussions, full and transparent financial disclosure, and for both parties to properly understand and obtain advice on the agreement increases both the fairness and the enforceability of the agreement. Rushing into a prenuptial agreement can remove the protection it would otherwise provide.

Fairness is Key

When deciding how much weight to give a prenuptial agreement, the court’s primary consideration is fairness. When assessing what is fair, the court must consider the three-stage test provided by the Supreme Court in the case of Radmacher v Granatino[1].

This includes asking:

  • Was the agreement freely entered into by both parties, without undue influence or external pressure?
    A court may also consider whether the marriage would have still gone ahead in the absence of an agreement in the terms signed.
  • Did each person fully understand the implications of the agreement?
    Before signing the agreement, each party should be aware of all the information that is material to their decision to sign the agreement, which can include exchanging full financial disclosure.
  • Would it be fair to hold both parties to the agreement in the circumstances at the time of separation?
    When properly prepared, a prenuptial agreement can significantly reduce uncertainty, save time and costs, and provide peace of mind throughout a marriage.

Already Married?

If you’re already married and didn’t have time to put a prenuptial agreement in place, a postnuptial agreement may still be an option. These agreements serve a similar purpose but are entered into after the wedding, allowing couples to clarify financial arrangements once the initial rush has settled. A postnuptial agreement can be used as a flexible way to address financial arrangements or changes in circumstances that may not have been accounted for before marriage.
