For most couples, the house is the largest single asset on the balance sheet. It is also the most emotionally loaded. The decisions you make here often shape the rest of the settlement: whether one of you can afford to keep living there, what happens to the mortgage, who gets the home equity, and what your tax position looks like the year after the divorce.
There are three real options, and each has financial, practical, and emotional tradeoffs. This guide walks through all three, plus the special situations (underwater mortgages, separate-property homes, investment properties) that come up regularly. Run the numbers for your situation in our Asset Division Calculator once you have read through the basics.
The three options
Option 1: Sell the house and split the proceeds. Both spouses walk away with cash. The mortgage is paid off, selling costs come off the top, and the remaining equity is divided according to your state's property law. This is usually the cleanest financial outcome.
Option 2: One spouse buys out the other. One spouse keeps the house and pays the other their share of the equity, typically by refinancing the mortgage and pulling cash out, or by trading other assets in the settlement. The remaining spouse takes their share and uses it for housing, debts, or savings.
Option 3: Defer the sale. Both spouses remain on the deed (and often the mortgage) for a set period, often until the youngest child finishes high school. The custodial spouse lives in the house with the children, and the property is sold and divided later.
Each option works in some cases and not others. Most divorces choose between Option 1 and Option 2; Option 3 is more common with younger children and is more legally complex.
Calculating home equity in a divorce
Equity is what you actually have to divide. The formula is simple but the inputs are not always agreed on:
Equity = Current market value - Mortgage balance - Selling costs
Each piece can be disputed:
- Current market value. A formal appraisal ($400 to $700) is the standard. Both spouses can hire their own appraisers, but the cost of competing appraisals usually exceeds any benefit. A single neutral appraiser, agreed by both spouses, is the cheaper path.
- Mortgage balance. Easy to verify with a current statement. If there is a HELOC or second mortgage, include those balances too.
- Selling costs. Standard practice is to deduct hypothetical selling costs even when the house is not actually being sold (since the spouse keeping the house will eventually sell it and incur those costs). Typical deductions: 5% to 6% real estate commission, 1% to 2% closing costs, plus any anticipated repair costs needed to sell.
Example: House appraises at $500,000. Mortgage balance is $280,000. Estimated selling costs at 7% of value are $35,000. Equity = $500,000 - $280,000 - $35,000 = $185,000.
If you each get half, each share is $92,500.
Community property vs equitable distribution
How the equity is divided depends on your state's property system.
Community property states. California, Texas, Arizona, Washington, Nevada, New Mexico, Idaho, Louisiana, and Wisconsin treat marital property (including a home bought during the marriage with marital funds) as 50/50 by default. Each spouse owns half. Deviation from a 50/50 split is rare and requires specific findings.
Equitable distribution states. The other 41 states apply factors to divide marital property "equitably," which can be 50/50 but does not have to be. Factors include the length of the marriage, each spouse's contributions, each spouse's economic circumstances, and (in some states) marital fault. In practice, most equitable distribution states still produce splits in the 45/55 to 55/45 range; a major skew is unusual unless one spouse has a strong claim of separate property contribution or there are dissipation issues.
Separate property contributions. If one spouse owned the home before the marriage, or used inherited funds for the down payment, that contribution may be recovered before the remaining equity is split. The exact treatment varies (some states allow a dollar-for-dollar trace; others require evidence of intent to keep the asset separate). If you used non-marital funds in the home, gather your records early.
The buyout process
If one spouse is keeping the house, the buyout has to actually happen. The typical sequence:
- Agree on equity. Use a neutral appraisal and an agreed mortgage balance. Decide whether selling costs are deducted.
- Determine the buyout amount. Half of the equity is typical (community property states) or whatever percentage the parties or court decide (equitable distribution).
- Decide on the funding source. The buyout can come from a cash-out refinance, a new mortgage in the keeping spouse's name only, a trade of other assets (one spouse takes the house, the other takes the larger retirement account), or some combination.
- Refinance or assume the mortgage. This is usually mandatory. If both names are on the existing mortgage, the lender does not care about your divorce decree; both spouses remain liable until the loan is paid off or refinanced. Most settlements require refinancing within 30 to 90 days of the divorce.
- Transfer the deed. A quitclaim deed transfers the leaving spouse's interest to the keeping spouse. This usually happens at the closing of the refinance.
The mortgage qualification problem. This is the issue that derails the most buyouts. The keeping spouse has to qualify for the new mortgage on a single income. If they cannot, the buyout fails, and the parties usually fall back to selling the house. Build mortgage qualification into your timeline early. Talk to a lender before signing the settlement, not after.
Lenders use the keeping spouse's income, debts (including any alimony obligations), and credit. Alimony and child support count as income for the recipient and as debt for the payer, which can change qualification numbers significantly. Get a preapproval based on the post-divorce financial picture, not the current one.
If qualification is borderline, options include: extending the mortgage term, reducing the loan amount by trading other assets, having the keeping spouse find a co-signer (rare and complicated), or renting the home for a period until income stabilizes.
Deferred sale arrangements
When children are young and stability is a priority, some couples agree to keep the home jointly for a set period. Common structure:
- Both spouses remain on the deed.
- One spouse (usually the custodial parent) lives in the home with the children.
- The mortgage continues to be paid, often by the resident spouse, sometimes shared.
- The home is sold at a triggering event: the youngest child turns 18 or finishes high school, the resident spouse remarries or cohabits, or a fixed date passes.
- At the trigger, the home is sold and the proceeds are divided according to a formula in the divorce decree.
The advantages are stability for the children and avoidance of a forced sale at a bad time. The disadvantages are significant:
- Both spouses remain on the mortgage. The leaving spouse cannot easily buy a new home, because lenders count the existing mortgage as a debt.
- Equity changes over time. The decree must address how appreciation and depreciation are allocated, who is responsible for major repairs, and what happens if the resident spouse stops paying.
- Disputes about the sale. When the trigger arrives, disputes often arise about the listing price, repairs, and timing.
- Tax issues. The home may no longer qualify for the full capital gains exclusion when sold (see below).
Deferred sale agreements should always be drafted carefully. Generic settlement language is rarely sufficient.
Capital gains tax: the $250,000 / $500,000 exclusion
The IRS exempts capital gains on the sale of a primary residence: up to $250,000 of gain for single filers, up to $500,000 for married couples filing jointly. To qualify, you must have owned and lived in the home for at least 2 of the last 5 years (with some exceptions).
Divorce affects this in several ways:
Sale during the marriage. If you sell while still married and file jointly, you get the full $500,000 exclusion.
Sale after divorce. Each former spouse can claim up to $250,000 if they meet the ownership and use tests. If one spouse stops living in the home after separation, they can still meet the use test if the other spouse is using the home under a divorce or separation agreement (Section 121(d)(3)).
Buyout. A transfer of the home from one spouse to another incident to divorce is not a taxable event. The keeping spouse takes the home with the original cost basis, which means the eventual sale by that spouse is calculated against the original purchase price plus improvements, not the buyout price.
This last point matters more than people realize. A spouse who buys out the other for $300,000 of equity in a $500,000 house with a $100,000 cost basis ends up holding all of the unrealized gain. If the home appreciates further before sale, they may exceed the single-filer $250,000 exclusion and owe capital gains tax that the original couple would have avoided.
If you are planning a buyout in a high-appreciation market, run the numbers on the eventual after-tax position, not just the equity at divorce.
What if neither spouse can afford the home?
This is more common than people expect. If the home was bought when both spouses were working and one is now lower-earning or out of the workforce, neither may qualify to refinance or pay the existing mortgage on a single income.
Options:
- Sell. Take the equity and use it for separate housing.
- Short-term continuation. Both spouses agree to keep paying the mortgage temporarily while one finds a new home or returns to work, then sell.
- Rent the home. Convert it to a rental. The income covers the mortgage, the property is held jointly until the market or finances support a sale. This requires careful documentation in the decree about repairs, vacancies, tax filings, and management.
Sometimes the right answer is to accept that the house cannot stay in the family. The financial freedom of a smaller home and clean balance sheet is often worth more than the emotional value of keeping the original home.
Special situations
Underwater mortgages. If you owe more than the home is worth, "splitting the equity" means splitting the debt. Options include short sale (with lender approval), continuing to pay until equity returns, or one spouse keeping the home and the associated negative equity.
Investment properties. Rental and second homes are usually treated like any other asset, but they have different tax characteristics (depreciation recapture, no Section 121 exclusion). Get a CPA's input before dividing them.
Premarital home. If one spouse owned the home before the marriage, the home itself may be separate property, but appreciation and any mortgage paydown during the marriage may have a marital component. The treatment varies by state.
One spouse on the deed only. Even if only one spouse is on the title, the home may still be marital property if it was acquired during the marriage with marital funds. Title is not destiny.
