House buyout and transfer of equity on divorce

One spouse keeping the family home almost always means a buyout: they pay the other for their share and take over the mortgage and the title on their own, so the leaving spouse comes off both. What you are buying out is a share of the equity, the home's value minus the outstanding mortgage, not a share of the full market value. If the home is worth £400,000 with a £150,000 mortgage, there is £250,000 of equity to divide, and a buyout is one spouse paying the other for their agreed slice of that £250,000.

The share each of you keeps is decided as part of the whole financial settlement, not split automatically down the middle. Before you fix on a number, our settlement range estimator gives an indicative range based on the factors courts actually weigh, so you can estimate your own likely split of the equity rather than assuming 50/50. This guide then walks through how a buyout is funded, the mortgage hurdle, the transfer of equity itself, the tax treatment, and the alternatives if a buyout does not work.

Working out each person's share

The maths starts simply. Take the current market value of the property, subtract the outstanding mortgage balance, and subtract any early repayment charge and the likely costs of the transfer. What is left is the equity. For the value, most couples use a single joint valuation or an average of two or three estate agent valuations rather than arguing over guesses. Using the £400,000 home from the introduction, the numbers stack up like this.

Step	Figure	Notes
Market value of the home	£400,000	Single joint valuation, or an average of two or three agent valuations
Outstanding mortgage	£150,000	Deduct any early repayment charge on top, if your deal carries one
Equity to divide	£250,000	Value minus mortgage; this is what the buyout is a share of
Buyout sum on an equal split	£125,000	Half the equity; the actual share is set by the whole settlement, not automatically 50/50
Stamp Duty Land Tax on the transfer	£0	Exempt when the transfer is made under a divorce agreement or court order
Capital Gains Tax on the transfer	£0	No gain, no loss for up to 3 tax years after the year of separation, unlimited under a formal agreement or court order

What that equity gets divided by is the harder question, and there is no automatic 50/50 rule in England and Wales. The court, and any negotiated settlement, works from the needs and sharing principles set out in the law: the housing and income needs of both parties, and above all the needs of any children, come first, and equal sharing of what the marriage built is the starting point where needs are already met. A parent who will house the children may keep a larger share; a shorter marriage with no children may point closer to each person's original contribution. The home is almost never looked at on its own, because it is weighed against pensions, savings and earning capacity in the round. Our complete guide to divorce financial settlements explains how that whole picture is assessed, and the financial settlements hub pulls the related topics together.

How a buyout is funded

Once you know the buyout figure, the next question is where the money comes from. There are three common routes, and they are often combined.

• Remortgaging to release capital. The most common route. The staying spouse takes out a new, usually larger, mortgage in their sole name, and the extra borrowing raised is paid to the leaving spouse for their share. This does two jobs at once: it produces the cash and it replaces the joint mortgage with a sole one.
• Using cash or other savings. If you have enough in savings, or family are able to lend or gift the money, you may be able to fund some or all of the buyout without new borrowing. You still have to deal with the existing lender to release the other spouse from the joint mortgage.
• Offsetting against other assets. Instead of paying cash, one spouse can keep more of the equity in exchange for giving up a share of other assets, most often pensions. This is where a buyout connects to the wider settlement, and it is an information point rather than a recommendation: whether to trade housing equity against pension value is a decision for advice on your own numbers. Our guide to pension sharing versus offsetting sets out how that trade-off is usually approached.

The mortgage hurdle: getting the leaving spouse released

For most couples the buyout stands or falls not on the divorce, but on the mortgage. When a home is in joint names, both people are jointly and severally liable for the whole mortgage, meaning the lender can pursue either of them for the full balance. A divorce does not change that. The leaving spouse is only released from the mortgage when the lender formally agrees to remove them, and lenders do not do that for free.

To release one borrower, the lender treats the staying spouse as if they were applying for the mortgage from scratch. They have to pass the lender's affordability assessment and credit checks on their income alone, without the departing spouse's earnings to lean on. This is the point where many buyouts run into trouble: a mortgage that was comfortable on two incomes may be unaffordable on one. If the staying spouse cannot qualify, the options are to raise a larger deposit to shrink the borrowing, extend the term, find a different lender, add a guarantor where a lender allows it, or accept that the home may have to be sold instead.

The site is not a mortgage adviser and does not recommend mortgage products. The practical point is simply that release from the joint mortgage is a separate hurdle from the divorce and the settlement, and it is worth checking affordability early, before a buyout is agreed on paper, so the deal does not collapse at the lender's desk.

The legal mechanics: transfer of equity

Changing the ownership of the home from joint names into one spouse's sole name is a transfer of equity. It is a conveyancing process, separate from both the divorce and the financial order, though in practice the three are coordinated. The gov.uk guidance on money and property when a relationship ends is a useful plain-English overview of how the home is dealt with.

The core steps are:

• Instruct a conveyancer or solicitor. They handle the transfer, the mortgage release and the Land Registry work. The staying spouse and the leaving spouse can use the same firm in a straightforward, agreed case, or separate firms where anything is contested.
• Get the lender's consent. The existing mortgage lender must agree to the transfer and to releasing the leaving borrower. This usually happens alongside the remortgage that funds the buyout.
• Complete Land Registry form TR1. This is the standard transfer deed for the whole of a registered title (form TR1 on gov.uk). It records the change of ownership and is signed and witnessed.
• Register the change at HM Land Registry. The conveyancer submits the TR1 and supporting documents so the title is updated into the sole owner's name.

Because the transfer is separate from the settlement, it should be tied to a financial consent order. A buyout agreed informally is not binding, and leaving it outside a court order both keeps financial claims open and risks losing the tax protections below, which depend on the transfer being made under a formal agreement or order.

Stamp Duty Land Tax on a divorce buyout

The good news for most couples is that a divorce buyout is generally free of Stamp Duty Land Tax. According to gov.uk, if you transfer an interest in land or property to your spouse or civil partner as part of an agreement or court order because you are divorcing, separating or ending a civil partnership, the transaction is exempt from Stamp Duty Land Tax, and there is no need to tell HMRC about it even where the value is above the SDLT threshold (gov.uk: SDLT transactions that do not need a return). The exemption sits in Schedule 3 of the Finance Act 2003.

Two conditions matter. The transfer has to be between the divorcing or separating couple, and it has to be made in connection with the ending of the marriage or civil partnership, under an agreement or court order. A transfer to a new partner, or an ordinary sale on the open market, is not covered. It is another reason to make sure the buyout is documented as part of a formal settlement rather than a casual arrangement.

Capital Gains Tax: the no gain, no loss window

Capital Gains Tax rarely bites on a family home buyout, for two reasons. First, the family home is normally covered by Private Residence Relief for the period it was your main residence. Second, transfers between separating spouses and civil partners are made on a no gain, no loss basis for up to 3 tax years after the tax year of separation, and with no time limit at all when the transfer is made under a formal divorce agreement or court order (Finance Act 2023, from 6 April 2023). That means no immediate CGT charge on the transfer itself.

The detail matters more in some situations than others, for example where one spouse has already moved out for a long time, where the home has been let, or where a second property is involved. For context, the CGT annual exempt amount for 2026/27 is £3,000, residential-property gains are taxed at 18% within the basic-rate band and 24% above it, and any UK residential property gain must be reported and paid within 60 days. We keep the full CGT detail, including the interaction with Private Residence Relief and worked examples, on our Capital Gains Tax on divorce hub, and HMRC's own guidance is in helpsheet HS281.

If a buyout does not work: the other options

A buyout is only one way to deal with the home, and it is not always the right one. If neither of you can afford to keep it alone, or the equity cannot be released cleanly, the main alternatives are:

• Sell and split. The simplest clean break: sell the home, pay off the mortgage and costs, and divide the net proceeds in the agreed shares. It severs both parties from the property and the mortgage, but it means everyone moves.
• Deferred sale: a Mesher order. The court postpones the sale until a trigger event, usually the youngest child turning 18 or finishing full-time education. One parent stays with the children until then, and the proceeds are divided at the trigger. It protects children's housing when an immediate sale or buyout would not, at the cost of keeping both parties tied to the property for years.
• Deferred sale: a Martin order. Similar to a Mesher, but typically allows one spouse to remain in the home for life, or until they remarry or move out, before the other realises their share. It is used where there are no dependent children but one party needs the housing security.

Which route fits depends on the numbers, the children and each person's housing needs, and the decision sits inside the wider settlement rather than being taken in isolation. If you are weighing a buyout against a sale or a deferred order, the guidance for divorcing homeowners pulls the home-specific issues together in one place.
