In the world of high-value divorces, the law often finds itself weighing more than just assets. It also has to weigh-up the importance of voices of those involved, especially those that have long been silenced. That’s what makes the recent Family Court ruling in PN v SA [2025] EWFC 141 so significant. It wasn’t just about a marital agreement. It was about power. About control. About the quiet, deliberate erosion of one woman’s ability to say no.
The case involved a wife who had signed a post-nuptial agreement at the insistence of her husband. On the surface, the agreement had the hallmarks of legitimacy. It was well written, properly signed, and supposedly entered into with legal advice. But behind the seemingly in-order paperwork lay something much darker – a trail of emotional manipulation and coercive behaviour that the court ultimately recognised for what it was.
Nuptial agreements
Nuptial agreements (whether signed before or during a marriage) can offer clarity, structure, and reassurance that they will be protected, financially, in the event that their relationship comes to an end. They can be especially helpful for people who are entering a second marriage, for business owners, or for those who have inherited wealth they want to ringfence. But such agreements are not watertight, and are not strictly legally binding. Courts will acknowledge their existence, and look to enforce them so long as they are entered into in the right spirit. But it has a duty to examine not just the words on the page, but the circumstances in which they were written.
That’s because consent often isn’t as simple as ticking a box, or adding a signature. It’s a structured process. And when that process is corrupted by pressure, isolation, or psychological control, the fairness of the entire agreement comes into question.
What happened in PN v SA?
In this case, the wife alleged that her husband had deliberately tried to isolate her from legal support. Her solicitor, alarmed by the husband’s behaviour, repeatedly warned that the wife was being deprived of independent advice and was showing signs of emotional distress. The court agreed. It found that the husband had created an oppressive environment – one in which the wife’s ability to exercise her own judgment had been eroded.
In legal terms, this is an example of what is referred to as ‘coercive and controlling behaviour’. It exemplifies a pattern of actions that amounts to emotional abuse, even if there are no visible scars. It’s the same legal concept that underpins criminal prosecutions under the Serious Crime Act 2015. And in this civil family law context, the court took it seriously. The judge concluded that the post-nuptial agreement could not stand as the wife had been signed it under duress.
And this wasn’t about one moment of pressure. The case outlined a long, strategic undermining of the wife’s independence. Crucially, the court’s ruling in favour of the wife here marks one of the clearest illustrations to date of the family courts applying the language of coercive control to invalidate a marital agreement.
Why the court stepped in
Family courts have always had the discretion to disregard nuptial agreements that are unfair. But the bar is high. Since the landmark 2010 Supreme Court case Radmacher v Granatino, the guiding principle has been this: if both parties enter into an agreement freely, with full understanding of its implications, and it doesn’t leave one of them in serious need, then the court should honour it.
But what happens when “freely” doesn’t really mean freely?
That’s the line PN v SA explores. The wife wasn’t physically forced to sign. She wasn’t locked in a room or threatened with violence. But her ability to make an informed, independent decision had been systematically dismantled. And that, the court said, was enough.
The judgment sends a clear signal: family courts are prepared to look beyond the formality of a written agreement and into the emotional reality of a relationship. Coercive control, which was once difficult to evidence and often overlooked, is now being recognised for the profound impact it has on a person’s autonomy and ability to give true consent.
If you’ve been pressured into a marital agreement
Many of those who are in abusive or high-control relationships often don’t even realise the full extent of what they’ve endured until they try to leave. Understandably, those who agreed to or signed legal documents during the relationship will worry that they are stuck with the consequences, and still powerless to act. But this is not necessarily true.
If this resonates with you, it’s important to know:
- You do not have to be bound by an agreement you signed under pressure, manipulation, or coercion.
- The court’s paramount concern is fairness, not formality.
- Legal advice is not just your right – it’s your lifeline in these situations.
The Family Court will look at the entire picture: whether there was full and honest financial disclosure, whether you had meaningful legal advice, and whether the agreement leaves you in a vulnerable financial position.
But more than that, it will ask whether you were truly in a position to say no.
Legal safeguards
To be taken seriously by the court, a nuptial agreement should meet certain criteria:
- Independent legal advice for each party
- Time for reflection (so not being signed at the last minute)
- Full financial disclosure
- No evidence of pressure, control, or manipulation
Even when all of these are present, the court retains discretion. But where they are missing, particularly where emotional abuse or controlling behaviour is involved, the agreement may be set aside.
A judgment that sends a message
This isn’t just a win for one woman. It’s a message to all spouses, particularly those in financially or emotionally unbalanced relationships – your consent matters. Coercive control is no longer something hidden in the shadows. The law, at its best, can be a tool for justice – not just procedure.
At Buckles, we believe that family law must serve not just the powerful, but the vulnerable. This judgment is a strong a reminder that all legal agreements entered into as a partnership must be built on genuine consent, independence, and equality of voice.
If you’re worried about the agreement you’ve signed, or about the relationship you’re in, we’re here to help. Quietly. Safely. And always on your side.
