Quick Answer
Buying out an ex-partner after divorce usually means one person keeps the home and compensates the other for their share of the equity. This can be done through remortgaging, a further advance, savings, a family gift, or a combination of these options. Lenders will assess affordability, credit history and loan-to-value before approving any new borrowing or removing a name from the mortgage.
Introduction
Buying out an ex-partner after divorce often involves raising enough money to pay them their agreed share of the property equity while taking over the mortgage in your own name. For some homeowners, this may mean remortgaging. Others may use savings, a further advance, a family gift, or a transfer of equity depending on their circumstances and lender criteria.
The biggest factor is usually affordability. A lender will normally want to check whether one person can comfortably manage the mortgage and any additional borrowing alone. Across Brighton, Hove, Worthing, Shoreham, Lewes and wider East and West Sussex, many separating couples are weighing up whether keeping the family home is financially realistic or whether selling may be the more practical option.
At Everest Mortgages, we regularly speak to homeowners who are trying to understand what options may be available, how lenders assess these situations, and what steps may help make the process more manageable.
The following options outline the most common ways homeowners across Brighton, Hove and wider Sussex may structure a buyout after divorce, depending on what is affordable and what lenders are likely to consider.
1. Remortgage to Raise the Money
For many separating couples, remortgaging is the most straightforward way to buy out an ex-partner after divorce. This usually means replacing the existing joint mortgage with a new mortgage in one person’s name while borrowing enough to pay the other person their agreed share of the equity.
Affordability Usually Becomes the Biggest Decision
The first question most lenders ask is whether one person can realistically afford the mortgage alone. This is particularly important if household income previously relied on two salaries. Lenders will normally assess income, regular commitments, debts, childcare costs and credit history before deciding how much they may be willing to lend.
Some lenders may also consider child maintenance or spousal maintenance as part of affordability if it can be evidenced and is expected to continue. Mortgage affordability checks have become stricter in recent years, with lenders stress-testing whether repayments would still remain manageable if rates increased further.
Property Value and Loan-to-Value Matter
The amount being borrowed compared to the property value is known as the loan-to-value (LTV). For example, borrowing £326,500 against a £403,000 property would create an LTV of around 81%. This matters because lenders often reserve their most competitive remortgage rates for lower LTV bands such as 60% or 75%. Higher LTV borrowing may reduce lender choice or increase monthly repayments depending on affordability and current interest rates.
In areas such as Brighton, Hove and Lewes, higher property values can sometimes create larger equity positions, which may help with buyouts. However, larger property prices can also increase the amount one person needs to borrow alone after separation.
Check the Costs Before Switching
Remortgaging can also involve additional costs, including valuation fees, solicitor fees, transfer of equity legal work and possible early repayment charges (ERCs). Many UK lenders charge ERCs of around 1% to 5% of the outstanding mortgage balance if a fixed-rate deal is ended early (GetPine.co.uk, Feb 21, 2026).
Remortgaging to buy out an ex-partner may involve changes to ownership and mortgage responsibility, so it is important to understand any legal implications around separation agreements or financial settlements. This is general mortgage information only and not legal advice; a solicitor should be consulted regarding divorce terms, ownership rights and any formal consent orders before proceeding.
2. Take a Further Advance with Your Current Lender
A further advance allows you to borrow additional money from your existing mortgage lender instead of moving to a completely new lender. For some homeowners going through divorce or separation, this can be a practical way to buy out an ex-partner while keeping the current mortgage deal in place.
This option is often considered when someone wants to stay in the family home but does not want to lose a competitive fixed rate secured in previous years. Across Worthing and Shoreham, some homeowners may prefer a further advance because moving to a full remortgage at current market rates could significantly increase monthly repayments.
How a Further Advance Usually Workss
With a further advance, the original mortgage normally stays untouched, while the extra borrowing is added as a separate sub-account with its own interest rate and repayment terms. This means you may end up managing two mortgage parts at different rates and end dates. For example, someone in Lewes with:
- an existing mortgage balance of £240,000 fixed at 2.1%, and
- an additional borrowing requirement of £70,000 to buy out an ex-partner
may keep the original mortgage rate while taking the £70,000 on a separate product at a newer rate closer to current market pricing.
A further advance may still be affected by how ownership is structured after separation, especially if both names remain on the mortgage or property. Any agreements between separating partners should be reviewed legally where relevant. This information is general only and does not replace legal advice on divorce settlements or property rights.
Affordability Still Matters
Even though you are staying with the same lender, affordability checks still usually apply because you are increasing the borrowing. Lenders will normally reassess:
- income,
- committed monthly spending,
- childcare costs,
- debts,
- credit history,
- and whether the mortgage would remain affordable if interest rates increased further.
In 2026, most mainstream UK lenders still commonly work within income multiples of around 4 to 4.5 times annual income, although some higher-income applicants may access higher multiples subject to affordability.
Can Your Ex Be Removed from the Mortgage?
A further advance alone does not automatically remove an ex-partner from the mortgage. If one person is taking full responsibility for the property, the lender must separately agree to release the other borrower from the mortgage liability. This often involves:
- affordability reassessment,
- legal work,
- and a transfer of equity completed by a solicitor.
Some lenders may agree to this at the same time as the further advance, while others may have additional requirements depending on income, equity and credit profile.
3. Use a Transfer of Equity
A transfer of equity is often used when one person wants to stay in the property after divorce while the other gives up their share of ownership. Instead of selling the home, the ownership structure is legally changed so that one partner becomes the sole owner, subject to lender approval.
This option is commonly used alongside a remortgage or further advance, but in some cases it may be possible without changing lenders if affordability still works on one income.
How the Equity Share Is Usually Worked Out
Before any ownership transfer takes place, the available equity normally needs to be calculated. This is typically based on:
- the current market value,
- the remaining mortgage balance,
- and any agreed financial settlement.
According to the UK House Price Index, the average property price in Brighton and Hove reached approximately £403,000 in February 2026, while detached homes in parts of East Sussex and Lewes often sit considerably higher depending on location and property type (ONS UK House Price Index, February 2026). Using a simplified example:
- Property value: £403,000
- Remaining mortgage: £250,000
- Estimated equity: £153,000
If both parties agree to a 50/50 split, the person remaining in the property may need to compensate the other by around £76,500 before legal costs and mortgage fees are considered. However, divorce-related equity divisions are not always equal. In practice, settlements can also consider:
- childcare arrangements,
- previous deposits,
- uneven income contributions,
- and wider marital assets.
Removing Someone from the Mortgage
One of the biggest misunderstandings during separation is assuming that removing someone from the property deeds automatically removes them from the mortgage. In reality, the lender must separately approve the release of the outgoing borrower.
If the remaining applicant cannot meet affordability requirements alone, the lender may refuse the transfer unless additional income, savings or borrowing adjustments are available.
This situation is increasingly common in Worthing and Shoreham, where one parent may want to keep the family home for stability after separation but still needs to satisfy modern affordability rules on a single income.
Legal Work and Solicitor Involvement
A solicitor is normally required to complete the transfer of equity process. This usually includes:
- preparing the TR1 transfer form,
- handling Land Registry changes,
- carrying out anti-money laundering checks,
- and managing lender legal requirements.
Recent conveyancing guidance suggests transfer of equity cases often take between 4 and 8 weeks once the lender has issued approval, although divorce-related cases can sometimes take longer if financial settlements are still being negotiated.
4. Use Savings to Reduce the Amount You Need to Borrow
Using savings to fund part of the buyout can reduce the amount you need to borrow from a lender, which may improve affordability and widen the range of mortgage options available after divorce.
This can be particularly helpful where one person wants to stay in the family home but their income alone may not support a larger remortgage. In areas such as Brighton, Hove and Lewes, where property values are often higher, even reducing the borrowing requirement by £20,000–£50,000 can materially affect monthly repayments and loan-to-value bands.
Lower Borrowing Can Improve Mortgage Options
Mortgage lenders usually price deals based on loan-to-value (LTV) bands. Even a relatively modest cash contribution can sometimes move the mortgage into a lower LTV bracket, which may improve available rates and reduce total interest costs over time.
For example, if someone in Hove needs to raise £60,000 to settle a buyout but contributes £25,000 from savings, the additional borrowing falls substantially. In some cases, this may help borrowers remain below key LTV thresholds such as 75% or 80%, where lender pricing can become more competitive.
Recent UK Finance lending data showed that average mortgage rates in early 2026 remained noticeably higher for borrowers above 85% LTV compared with lower-LTV borrowing (UK Finance mortgage market data, 2026).
Keep Emergency Savings in Mind
One of the biggest mistakes after separation is using every available savings account to complete the buyout while leaving little financial buffer afterwards. Single-income homeownership can involve unexpected costs such as:
- boiler repairs,
- childcare changes,
- legal fees,
- or temporary income disruption.
Homeowners across Worthing and Shoreham often focus heavily on raising enough money to complete the buyout, but keeping some savings aside can also be important for longer-term stability after separation. We regularly help clients balance the desire to stay in the family home with the need to keep an emergency financial buffer in place once the settlement has completed.
5. Use a Family Gift
Some separating couples use financial support from parents or relatives to help fund a buyout after divorce, particularly where affordability is close but not quite sufficient for the required borrowing.
In practice, family support is increasingly common in UK property transactions. Recent mortgage market guidance suggests around 40% of first-time buyers now receive some form of family financial assistance (Bank of Mum and Dad, Early 2026).
Gift or Loan: The Difference Matters
Mortgage lenders usually treat gifted money very differently from repayable family loans. If the money must eventually be repaid, lenders may include those repayments within affordability calculations, which can reduce borrowing capacity.
If the funds are a genuine gift with no repayment expected, lenders are often more comfortable considering the arrangement. Most lenders therefore require a signed gifted deposit or gifted equity letter confirming:
- the amount being provided,
- the relationship between the parties,
- that repayment is not expected,
- and that the person providing the money will not own part of the property.
According to Halifax and NatWest, gifted funds normally must be unconditional and not create any legal interest in the property.
Source of Funds and AML Checks
Solicitors and lenders are also required to carry out anti-money laundering (AML) checks on larger gifted sums. This often includes:
- proof of ID,
- bank statements,
- evidence showing where the money originated,
- and confirmation that the funds were obtained legitimately.
According to Nationwide’s mortgage gifting guidance, larger gifted sums, particularly those above £10,000 will often require additional source-of-funds checks and supporting documentation during the mortgage and conveyancing process
This can become particularly important where:
- multiple relatives are contributing
- money has come from overseas
- or large cash transfers appear shortly before the mortgage application.
At Everest Mortgages, we regularly help clients across East and West Sussex understand how lenders may assess gifted funds before they formally apply, helping avoid delays later in the conveyancing process.
6. Agree a Deferred Payment or Delayed Settlement
In some divorce cases, the most practical solution is not to raise the full buyout amount immediately but to agree a deferred payment or delayed settlement. This means one partner remains in the property for a defined period, while the final equity payment to the other party is postponed until a future trigger event such as a sale or remortgage.
This type of arrangement is often used where the property has enough value to eventually provide a fair split, but current affordability or market conditions make an immediate buyout difficult. As per UK guidance on property division, courts can allow arrangements where sale or equity division is delayed until a set event occurs, particularly where children are involved or where an immediate sale would create financial pressure for both parties.
In practice, this option may appear in settlements across areas like Worthing or Shoreham where one person remains in the family home temporarily while financial stability is being re-established after separation. The key point is that ownership rights are not automatically removed at this stage, and both parties may remain financially linked to the property until the agreed settlement is completed.
It is important to understand that a deferred arrangement does not remove mortgage responsibility. If both names remain on the mortgage, both parties are still legally liable for repayments until a formal transfer or sale takes place. This is why lenders and solicitors usually need to be involved to ensure the agreement is properly documented and enforceable.
Because these arrangements depend heavily on personal circumstances, including income, equity position and family needs, they are typically structured with legal advice alongside mortgage advice to avoid future disputes.
7. Sell the Property and Split the Equity
Selling the property and dividing the proceeds is often considered when a clean financial break is the most practical outcome after divorce. This option removes joint ownership and joint mortgage liability, allowing both parties to move forward independently.
In many cases, selling becomes the preferred route when:
- affordability on a single income is not realistic,
- there is disagreement over buyout terms,
- or there is insufficient borrowing capacity to remortgage in one name.
UK property guidance notes that when a jointly owned home is sold, the proceeds are divided according to the financial agreement or court order, after the mortgage and selling costs are repaid.
This is often seen in situations across Brighton and Hove where equity levels are higher, meaning both parties may be able to reset financially more easily through a sale. It is also common in Lewes where property values can create meaningful equity, but not always enough affordability for one person to take on the full mortgage alone. In Worthing and Shoreham, selling is sometimes chosen when maintaining a single-income mortgage would place too much long-term pressure on household finances.
Selling the home also simplifies the equity calculation. Once the sale completes, the remaining funds after mortgage redemption and fees are typically split based on the agreed settlement, which may or may not be a strict 50/50 division depending on contributions and legal agreements.
While this option can feel like a major step, it is often the cleanest way to remove financial ties and reduce ongoing risk, particularly where future affordability or mortgage eligibility is uncertain.

FAQs — Buying Out Your Ex-Partner After Divorce
1. Do I need to remortgage to buy out my ex?
Not always. Some people use a remortgage, but others may use a further advance, savings, family support, or a transfer of equity depending on affordability and lender criteria.
2. Can I borrow more to pay my ex their share?
Yes, in many cases lenders may allow additional borrowing if you meet affordability checks. This can be done through a remortgage or a further advance, depending on your current mortgage deal.
3. How is equity calculated during a divorce?
Equity is usually the property value minus the outstanding mortgage balance. The remaining amount is then divided based on the agreed settlement or legal arrangement.
4. Can I use savings to reduce the buyout amount?
Yes, savings can reduce how much you need to borrow, which may improve affordability and potentially lower the loan-to-value level, depending on your mortgage structure.
5. Can family members gift money towards the buyout?
Yes, family gifts are commonly accepted by lenders, but they usually require a gift letter confirming the money is not repayable and standard source-of-funds checks.
6. What if I cannot afford the buyout?
If affordability does not work on a single income, alternatives may include selling the property, delaying the settlement, or exploring different borrowing structures with lender approval.
