When planning a wedding, conversations about love, family, and the future dominate. Yet, one topic often overlooked is financial protection. Prenuptial and postnuptial agreements, commonly called prenups and post-nups are tools designed to safeguard wealth and clarify financial arrangements should the marriage end. While they may seem unromantic, they can be invaluable for couples who want certainty and fairness.
What Are Prenups and Post-Nups?
A prenuptial agreement is a legal document signed before marriage, outlining how assets will be divided if the relationship breaks down. Similarly, a postnuptial agreement is signed after marriage but serves the same purpose. Both agreements can also detail how finances will be managed during the marriage.
Think of these agreements as a roadmap for an event you hope never happens, similar to writing a will. You don’t plan for disaster because you expect it, but because you want clarity if it occurs.
Are They Legally Binding?
In England and Wales, nuptial agreements are not automatically binding. Courts retain discretion under section 25 of the Matrimonial Causes Act 1973 to decide what is fair. However, since the landmark case of Radmacher v Granatino (2010), courts generally uphold agreements that meet three criteria:
Freely entered into (no pressure or duress)
Full understanding of implications (financial disclosure and independent legal advice)
Fairness (meeting both parties’ needs)
If these conditions are met, courts give significant weight to the agreement, even if they don’t enforce it entirely.
Why Consider a Prenup or Post-Nup?
The starting point for asset division in divorce is usually 50/50, as established in White v White (2000). This includes property, savings, pensions, and even business interests. For individuals with substantial assets, business ventures, or anticipated inheritances, this can feel disproportionate.
Take Annie’s story. Annie built a successful aesthetics business before marriage and anticipated significant growth. Without a prenup, her business, additional properties, and income became part of the matrimonial pot when her marriage ended. Adam, her spouse, had sharing claims over everything, despite Annie’s entrepreneurial efforts. A well-drafted prenup could have limited Adam’s claims to joint assets, protecting Annie’s business and future wealth.
Common Misconceptions
Many believe prenups are only for the ultra-wealthy. In reality, they’re useful for anyone with:
Unequal contributions to property purchases
Family businesses or professional practices
Expected inheritances
Children from previous relationships
Post-nups serve the same purpose for couples who marry without a prenup but later wish to protect wealth, perhaps after starting a business or receiving an inheritance.
How to Make Them Effective
A poorly drafted agreement can be worse than none at all. Courts disregard agreements that lack fairness or transparency. For example, one case involved a wife who signed a prenup on her wedding day without independent advice or financial disclosure. The agreement gave her nothing, even after having children. Unsurprisingly, the court set it aside.
To maximise enforceability:
Sign at least 28 days before the wedding, ideally in discussion for months prior
Exchange full financial disclosure (Form E is often used).
Obtain independent legal advice for both parties.
Include review clauses for major life changes, such as children.
Real-Life Benefits
Even if a court doesn’t uphold every term, a nuptial agreement influences outcomes. Judges often respect the couple’s intentions, provided needs are met. For instance, limiting claims to joint assets while ensuring the other spouse has enough to rehouse can be considered fair.
What About Unmarried Couples?
While outside the scope of nuptial agreements, cohabiting couples face similar risks. Without protection, property ownership defaults to legal title, which can create unfairness. Tools like declarations of trust and cohabitation agreements clarify ownership and financial responsibilities, avoiding costly disputes later.
Final Thoughts
Prenups and post-nups aren’t about expecting failure, they’re about planning responsibly. They provide clarity, reduce conflict, and protect what matters most. If you’re considering marriage or already married and want to safeguard your assets, speak to a qualified solicitor. These agreements must be tailored to your circumstances and drafted correctly to stand up in court.
