Divorce With a Family Business: Valuation and Tax Traps in 2026/27
How a family business is valued and divided on divorce, and the Capital Gains Tax and Business Asset Disposal Relief pitfalls of transferring or selling shares as part of a settlement in 2026/27.
Quick answer
A family business rarely gets split in half on divorce — instead, it's valued as part of the overall matrimonial pot, and the settlement usually involves one spouse keeping the business (often with other assets, like the family home, going the other way) rather than both ending up as co-owners. The tax question that trips people up isn't who keeps the business — it's how share transfers and any eventual sale are taxed.

Courts typically require an independent business valuation (often a joint single expert) reflecting the company's realistic value — not simply book value or a hopeful multiple the owning spouse might quote. This valuation feeds into the overall matrimonial asset schedule, alongside the family home, pensions and savings, informing how the overall settlement is structured.
The CGT reform for separating couples
Since the reform to CGT rules for separating spouses, transfers of assets — including business shares — between spouses continue to receive no-gain/no-loss treatment (meaning no immediate CGT charge) for up to three years after the year of separation, and without any time limit at all if the transfer is made under a formal divorce or separation agreement approved by the court. This closed a significant historic trap where transfers made even slightly too late in a divorce process could trigger an unexpected CGT bill.

If keeping the business intact isn't practical and shares (or the whole business) must be sold to a third party to raise settlement funds, that's an ordinary CGT disposal. The selling spouse may be eligible for Business Asset Disposal Relief — an 18% rate on qualifying gains up to a £1 million lifetime limit — provided they've met the ownership and employment/office-holder conditions for at least two years before the sale.
Future eligibility after a share transfer
A spouse who receives shares as part of a divorce settlement, intending to run the business going forward, needs to separately establish their own qualifying period for Business Asset Disposal Relief from the date they become genuinely involved — inheriting shares via divorce doesn't automatically inherit the other spouse's accumulated qualifying history.
Bottom line
Get an independent valuation early, use the no-gain/no-loss window (now extended to three years, or indefinitely under a formal agreement) to structure any share transfer without triggering CGT, and take specific advice before any eventual sale if Business Asset Disposal Relief matters to the numbers.

Frequently asked questions
Does the family court simply split the business 50/50?
No — the court considers the business as part of the overall matrimonial assets, but the actual division depends on factors including each party's contribution, needs, the business's ongoing viability, and whether one spouse is genuinely operational in the business day-to-day. A clean 50/50 split of shares is unusual where only one spouse runs the business.
Is transferring shares between spouses as part of a divorce settlement subject to CGT?
Transfers between spouses or civil partners are generally free of Capital Gains Tax while you're still married or in a civil partnership, and this no-gain/no-loss treatment now extends for transfers made up to three years after separation, or without time limit if made under a formal divorce settlement agreement, following the CGT reform for separating couples.
What happens if the business has to be sold to fund the settlement?
A sale to a third party to raise cash for a settlement is a normal disposal for CGT purposes, potentially qualifying for Business Asset Disposal Relief (18% rate on the first £1 million of qualifying lifetime gains) if the seller meets the ownership and involvement conditions, rather than the standard higher CGT rates.
Can a spouse who isn't operationally involved still claim a share of the business value?
Yes — matrimonial law looks at the business as a shared marital asset built during the relationship regardless of who was the named owner or operator, though the court will weigh the practical reality of keeping the business intact and functioning against a purely mathematical asset split.
Does Business Asset Disposal Relief survive a change in shareholding after divorce?
BADR eligibility depends on meeting specific ownership and employment/office-holder conditions for at least two years before disposal — a share transfer as part of divorce can affect whether the receiving spouse meets those conditions for their own eventual future disposal, so this needs specific advice rather than assumption.
