Most people have heard of a prenuptial agreement, but fewer know about a postnuptial agreement.

A postnuptial agreement (or “postnup”) is an agreement made after you’ve got married or entered into a civil partnership. It records what you and your partner agree should happen to your finances, property and other assets if your relationship were to end in the future.

No one gets married expecting to separate. But life changes. Relationships change. Financial circumstances change too.

For some couples, putting a postnuptial agreement in place isn’t about planning for divorce. It’s about creating certainty and taking away one of the biggest sources of stress in a relationship – money.

Why would a couple have a postnuptial agreement?

There are lots of reasons.

Perhaps one of you has received an inheritance, started a business or want to protect children from a previous relationship, who have now made their way to adulthood.

Sometimes it’s simply because your financial circumstances are very different from when you got married.

And sometimes it’s because your marriage has hit a difficult patch.

Statistics show that women aged between 40 and 44, and men aged between 45 and 49, have the highest rates of divorce. For opposite-sex couples, marriages ending in divorce have lasted, on average, just under 13 years.

Whilst statistics don’t tell the story of every relationship, they do remind us that many couples reach a point where they start asking difficult questions about their future together.

Taking money out of the equation

When a relationship is under pressure, worries about money can make everything feel even harder.

Clients will ask questions like:

• What would happen to the house?
• Would I be financially secure?
• What happens to the business?
• What if we’ve both put money into different things over the years?
• How would the children be provided for?

These are completely natural concerns.

The problem is that worrying about the financial consequences can sometimes stop people from thinking clearly about what they actually want.

A postnuptial agreement can help change that.

By agreeing financial arrangements in advance or at the start of relationship difficulties, both people know where they stand. It provides clarity and removes uncertainty.

Once that uncertainty has gone, couples are often able to focus on what really matters – their relationship.

Removing Money from the Equation

I recently worked with a couple in mediation after one of them had been unfaithful.  This infidelity had caused them to question their relationship. They still loved each other, but there was a great deal of hurt, and they had started couples counselling to see whether the relationship could be repaired.  One thing they both agreed on was this:

They didn’t want money to influence their decision.

If they stayed together, they wanted it to be because they had rebuilt trust.

If they separated, they wanted it to be because the relationship could not be repaired.

Neither of them wanted financial worries to become the reason they stayed in an unhappy marriage or left one that could still be saved.

Together, we agreed the terms of a postnuptial agreement that gave them both financial certainty.

Once they knew where they stood financially, they were able to put their energy into counselling and working on their relationship, knowing that whatever decision they eventually made would be based on their feelings for each other—not on fear about money.

I’ve always thought that was one of the most positive uses of a postnuptial agreement.

 

Don’t wait until you’ve made a decision

Many people think they should only speak to a family lawyer once they’ve decided to separate.

In reality, getting advice earlier can be incredibly helpful, or as the couple above, sitting together in a mediation setting and working through the terms of the agreement, together provides a unified approach, which is often crucial at this juncture of their relationship.

Knowing your options, understanding your rights and getting clear advice often helps people feel more in control at a time when life can feel anything but.
