A prenup is a valuable tool for couples who want to establish clear financial boundaries before marriage. When created and maintained properly, it can provide peace of mind and ensure that both parties are treated fairly in the event of a divorce. While no one enters a marriage expecting to divorce, making these arrangements while in a positive and rational mindset allows for fair decision-making. By considering a prenup during a harmonious time in your relationship, you can protect both parties and ensure the best possible outcome if challenges arise in the future.

In recent years, prenuptial agreements have gained popularity, not just among wealthy individuals, but also among younger couples and those entering second marriages. Historically, prenups were often viewed with suspicion, as though planning for a potential divorce was unromantic or pessimistic. However, attitudes have shifted as more people recognise the importance of financial transparency and fairness in marriage. A well-drafted prenup can actually strengthen a relationship by fostering open communication about money and expectations, ultimately building a stronger foundation for the marriage.

In this guide, the family law solicitors at Scott Bailey have answered some of the most commonly asked questions about prenups.

What is a prenup?

A prenuptial agreement, commonly referred to as a “prenup,” is a legal document that a couple enters into before getting married. The primary purpose of a prenup is to protect each party’s assets in the event of a divorce. It outlines how assets and finances will be divided and can also cover other aspects, such as spousal support.

A prenup can cover a wide range of assets, including real estate, business interests, savings, investments, and even future inheritances. It can also address liabilities, ensuring that any existing debts are clearly allocated between the parties. The importance of full financial disclosure cannot be overstated; both parties must be completely transparent about their financial situations. Failure to do so could result in the prenup being challenged in court and potentially deemed invalid. By disclosing all assets and liabilities upfront, both parties can enter the marriage with a clear understanding of their financial standing.

It is also essential for both parties to seek independent legal advice before entering into a prenup. This ensures that both understand the implications of the agreement and that it is fair and reasonable for both sides.

What does a prenup do?

A prenup sets out the terms for how a couple’s assets and financial matters will be handled if the marriage ends in divorce. This includes determining what happens to property, savings, investments, and even debts. It can also outline provisions for spousal support and address other financial matters, helping to avoid disputes and lengthy court battles in the future.

In addition to protecting current assets, a prenup can also outline how future earnings will be handled, particularly if one partner expects a significant increase in income or if the couple plans to start a business together. Intellectual property, such as patents, copyrights, and trademarks, can also be addressed in a prenup. Another key consideration is how the prenup will account for future changes, such as career shifts or relocations, which could impact the financial dynamics of the marriage. By addressing these potential scenarios, a prenup provides a comprehensive framework that adapts to the couple’s evolving circumstances.

Are prenups legally binding in the UK?

Prenuptial agreements are not automatically legally binding in the UK. However, they are more likely to be enforceable if certain conditions are met. The courts will consider whether the prenup is fair, whether both parties had independent legal advice, whether there was full financial disclosure, and whether the agreement was made well in advance of the wedding without any undue pressure.

When assessing a prenup, UK courts will consider several factors, including the timing of the agreement, the fairness of its terms, and whether both parties received independent legal advice. A landmark case, Radmacher v Granatino, significantly influenced how prenups are treated in the UK. The case established that, provided a prenup is entered into freely by both parties with a full understanding of its implications, it is more likely to be upheld by the courts. This ruling has made prenups a more robust option for protecting assets, although the court retains the discretion to override the agreement if it deems it unfair or prejudicial to either party.

In the UK, the Matrimonial Causes Act governs financial arrangements in the event of a marriage breakdown. Therefore, while a prenup is a useful tool, it cannot override the court’s duty to ensure that neither party is prejudiced by the agreement.

How much does a prenup cost?

The cost of drafting a prenuptial agreement can start from as little as £1,500, depending on the complexity of the case. This fee generally covers the cost of obtaining legal advice and the time spent drafting the agreement. If further negotiations are needed, particularly if one party feels the terms are unfair, the costs can increase due to additional time spent revising the document.

Factors that may influence the cost include the complexity of the couple’s financial situation, the need for multiple revisions, and the inclusion of international assets or properties. More complex financial situations, such as those involving multiple businesses or significant overseas investments, may require more extensive legal work, thereby increasing the cost. While the upfront expense of a prenup may seem high, it can save considerable time, money, and emotional stress in the event of a divorce, making it a worthwhile investment in the long run.

Can a prenuptial agreement be signed after marriage?

Once a couple is married, they can no longer sign a prenuptial agreement. However, they can enter into a postnuptial agreement, which serves a similar purpose. Postnuptial agreements can be more complex to negotiate since the couple is already married, but they are still a viable option for setting out terms for asset division and financial arrangements.

Couples may choose a postnuptial agreement instead of a prenuptial agreement for various reasons. Significant changes in financial circumstances, such as an inheritance or a major career change, might prompt the couple to formalise their financial arrangements after marriage. Additionally, couples who have reconciled after a period of separation might use a postnup to establish new terms that reflect their renewed commitment. While both prenups and postnups serve similar purposes, postnuptial agreements can be more challenging to enforce, as courts may scrutinise them more closely, particularly if they were signed during a period of marital tension.

Who does it benefit?

A prenup can benefit both parties by providing clarity and security regarding financial matters. It is particularly useful for individuals entering a second marriage or those with significant assets. It ensures that both parties understand what will happen financially in the event of a divorce, potentially avoiding conflicts and preserving assets that were acquired before the marriage.

Prenups can also provide crucial protection for children from previous relationships, ensuring that their inheritance is safeguarded and that family businesses remain within the family. For individuals with complex financial portfolios or those who want to keep certain assets separate, a prenup offers a clear and legally recognised way to do so. Beyond financial protection, a prenup can also offer peace of mind, allowing both parties to enter the marriage with confidence that their financial future is secure, no matter what happens.

When is a prenup brought into effect?

A prenuptial agreement takes effect upon marriage and can be invoked immediately if the couple decides to divorce. It is crucial that the prenup is finalised well before the wedding date to avoid any suggestion that one party was coerced into signing it under duress.

How long does it last?

A prenup lasts for the duration of the marriage unless it is replaced or updated. It is generally recommended that couples review and update their prenup every 3-5 years, or whenever significant life changes occur, such as the birth of a child or a major shift in financial circumstances. If a prenup is not updated to reflect these changes, its enforceability may be compromised.

Prenups are not just about protecting assets; they also provide a framework for fairness in case of a divorce. For example, a prenup signed in the early years of marriage might not account for changes like one partner giving up their career to raise children. In such cases, the prenup needs to be updated to ensure that it remains fair and enforceable.

What to include in your prenuptial agreement:

  1. When creating a prenup, it’s essential to consider the following key components:
  1. Basic information such as agreement details, governing law (e.g., laws of England and Wales), and how costs associated with the prenup will be shared
  2. Property and financial arrangements such as joint purchases, inheritance and estate planning, business interests, existing properties, money, income, and how debts and liabilities will be managed
  3. Debt responsibility for both pre-existing and future debts
  4. Retirement and pensions
  5. Insurance policies such as life or health insurance
  6. Provisions for major life events such as relocations or significant inheritances
  7. Spousal and child arrangements including maintenance
  8. Property rights and claims and ‘clean break on death’ clauses
  9. Review clauses (provisions to periodically review and update the prenup as circumstances change) and severability to ensure that if any part of the prenup is found invalid, the rest remains enforceable

Including these elements in a prenup can help ensure that both parties’ assets and interests are protected, providing clarity and security in the event of separation or other significant life changes.
