How to Protect Your Business During Divorce

10th December 2025

If you own a business and your marriage ends, one of your biggest worries is probably what happens to the company you have built. Will your spouse get half? Will you be forced to sell? Can your business partners push you out?

The good news is that there may be ways to protect your business interests in divorce, and the earlier you plan, the better. Whether you are getting married, already married, or separating, understanding your options now can save your business and your peace of mind later.

Here is what you need to know about protecting your business in divorce.

Why Businesses Are Vulnerable in Divorce

In England and Wales, courts treat businesses as marital assets if they were built or grew during the marriage. Even if your spouse never worked in the business, they may have a claim to a share of its value.

This creates several problems:

You might need to buy out your spouse, which requires significant cash
• Your business might need to be valued, which is expensive and disruptive
• Your business partners might worry about an ex-spouse gaining a stake
• In some cases, selling the business might be the only way to divide assets fairly

The best way to avoid these problems is to plan ahead with legal agreements that clearly state what happens to your business if your marriage ends.

Prenuptial Agreements: Protecting Your Business Before Marriage

A prenuptial agreement (prenup) is a legal document you and your partner sign before you get married. It sets out how you want your assets divided if you divorce, including protecting business interests.

How Prenups Protect Businesses

A well-drafted prenup can specify that your business remains yours in the event of divorce. This is particularly important if:

• You owned the business before marriage
• You have business partners
• Your family helped fund the business
• The business is your main source of income

Example: Sarah owns a marketing agency she started five years before meeting Tom. When they decide to marry, Sarah gets a prenup stating the business remains hers. If they divorce ten years later, the prenup may protect her business from being divided, though Tom may still have claims to other marital assets.

Are Prenups Legally Binding?

Prenups are not automatically legally binding in England and Wales, but courts take them very seriously if properly prepared. If your prenup is properly prepared, both parties had independent legal advice, and it is fair, courts will usually uphold it.

The key is making sure your prenup meets certain requirements:

Both parties have their own solicitor
• Full financial disclosure is provided
• It is signed at least 28 days before the wedding
• The agreement is fair and does not leave either party in financial hardship.

A prenup that protects your business while still providing fairly for your spouse is much more likely to be upheld by a court.

Postnuptial Agreements: Protecting Your Business After Marriage

If you are already married, you can still protect your business with a postnuptial agreement (postnup). This is essentially the same as a prenup, but signed after marriage rather than before.

When to Consider a Postnup

Postnups are particularly useful in these situations:

You started a business after getting married
• Your business has grown significantly
• You are taking on new business partners who want protection
• You inherited money and invested it in the business
• Family members wish to transfer shares in the business to you as part of their succession or tax planning.

Example: James and Emma have been married for eight years. James recently inherited £200,000 from his father and wants to invest it in his construction business. Emma agrees she does not want a claim to this inheritance or the business value it creates, so they sign a postnup protecting these assets.

Shareholders Agreements: Business Protection Beyond Marriage

If you own a business with others, a shareholders agreement is essential for protecting everyone, not just you. It can:

  • Prevent an ex-spouse from becoming a shareholder
  • Require shares to be sold back to the business on divorce
  • Set valuation methods to avoid disputes
  • Protect business decisions from outside interference

A shareholders agreement can works alongside any prenup or postnup you have. Your business partners will thank you for having this in place because it protects the business from disruption if your marriage ends.

What Happens to Your Business Without These Agreements?

If you do not have a prenup, postnup, or shareholders agreement, your business is treated like any other marital asset. This means the court is more likely to:

Order a Valuation

This is expensive (often £5,000-£20,000 or more) and invasive. An accountant will go through your books, turnover, assets, and liabilities to determine what your business is worth.

Divide the Business Value

Options include:

You keep the business and pay your spouse their share from other assets
• You buy out your spouse with a lump sum (possibly requiring a loan)
• You sell the business and split the proceeds
• Your spouse receives ongoing payments from business profits

None of these options are ideal, which is why planning ahead with legal agreements is so important.

Common Myths About Protecting Businesses in Divorce

Myth 1: My spouse has no claim because they do not work in the business
Reality: Courts can still award your spouse a share of the business value, especially if they supported you by looking after children or managing the home while you built the business.

Myth 2: Putting the business in someone else name protects it
Reality: Courts can see through these arrangements. Transferring assets to avoid a fair settlement can backfire badly and may even constitute fraud.

Myth 3: Prenups are not worth doing because courts ignore them
Reality: Properly prepared prenups are taken very seriously by courts. While not automatically binding, they are usually taken in account if fair and properly executed.

How Much Does It Cost to Protect Your Business?

Legal fees for prenups and postnups typically range from £1,500 to £5,000 depending on complexity. This might sound expensive, but compare it to the cost of contested divorce proceedings involving a business:

Business valuation: £5,000-£20,000+
• Legal fees for contested proceedings: £20,000-£100,000+
• Potential buyout or sale of your business: Hundreds of thousands or more

Investing in legal protection now is far cheaper than dealing with an unprotected business in divorce later.

What If You Are Already Separating?

If you are already going through separation or divorce and do not have a prenup or postnup, you can still negotiate terms that protect your business.

Options include:

  • Offset the business value against other assets (e.g., the family home)
  • Agree a buyout payment plan over time
  • Structure maintenance payments instead of dividing the business
  • Use mediation to reach an agreement that works for both sides and to avoid court.

The earlier you get legal advice, the more options you have. Waiting until court proceedings are underway limits your choices and increases costs.

Getting Started With Business Protection

If you want to protect your business from divorce, the first step is speaking to a specialist family law solicitor who understands business assets.

They will:

Assess your specific situation and business structure
• Advise whether a prenup, postnup, or shareholders agreement is best
• Draft the agreement to ensure it is legally sound and fair
• Work with your partner solicitor to ensure both parties are protected

The conversation does not have to be awkward. Many couples see these agreements as practical planning rather than a lack of trust. Think of it like business insurance: you hope you never need it, but you are glad it is there if things go wrong.

Quick Answers: Business Protection FAQs

Can my spouse take half my business in divorce?

Potentially, yes. If the business was built or grew during the marriage, courts can treat it as a marital asset. However, prenups, postnups, and negotiations may protect your business from being divided.

Do prenups really work in the UK?

Yes, when properly prepared. Courts in England and Wales take prenups very seriously and usually uphold them if both parties had legal advice, provided full financial disclosure, and the agreement is fair and meets needs.

Is it too late to protect my business if I am already married?

No. You can sign a postnuptial agreement after marriage if your spouse is willing to sign. 

What if my business partners want protection from my divorce?

A shareholders agreement can protect all business partners by preventing ex-spouses from gaining shares or control. This works alongside your prenup or postnup.

How much does a prenup cost?

Typically £1,500-£5,000 depending on complexity. This is far cheaper than defending your business in contested divorce proceedings, which can cost tens of thousands.
