If your partner wants to buy you out of the house, the price you should accept is your share of the home’s equity — the appraised value minus the mortgage balance and any other liens — adjusted for unequal contributions and occupancy, and you shouldn’t sign anything that transfers your ownership until your name is also coming off the mortgage. Everything else in a buyout is detail around those two points, and the detail changes depending on whether you and your partner are married.
Know What You Actually Own
Pull the deed before you talk numbers. The form of ownership listed on it controls your legal share and your options for transferring it.
Joint tenants hold equal shares. If the deed names you and your partner as joint tenants, you each own 50% regardless of who paid the larger down payment or more of the mortgage. Joint tenancy also carries a right of survivorship: if one owner dies, their share passes automatically to the other rather than to heirs.
Tenants in common can hold unequal shares — 60/40, 70/30, whatever the deed records. There’s no survivorship, and each owner can sell or transfer their share independently. If the deed says “tenants in common” without listing percentages, most jurisdictions presume equal shares unless someone proves otherwise.
A title company or real estate attorney can pull the deed and interpret it for a small fee. That’s worth doing before negotiations get serious, because the deed sets the default each side is negotiating from.
Pricing the Buyout
The buyout price is not half the home’s value. It’s your share of the equity, which is value minus debt. If the home appraises at $400,000 and the mortgage balance is $150,000, the equity is $250,000, and an equal co-owner’s starting share is $125,000.
Get that appraised value from a licensed appraiser, not from your partner’s estimate or an online tool. You and your partner have opposite incentives on price, and an independent appraisal is the cleanest way to shut that fight down. Appraisers follow the Uniform Standards of Professional Appraisal Practice, which exist to keep valuations objective.1Appraisal Subcommittee. USPAP Compliance and Appraisal Independence A single-family appraisal typically runs a few hundred dollars. A real estate agent’s comparative market analysis is a cheaper alternative, and online estimates are fine as a rough starting point but not as the basis for a six-figure decision. If you and your partner can’t agree on one appraiser, each hire your own and average them. If even that stalls, a mediator or court can appoint a neutral.
Adjustments for Contributions
If one partner put up a larger down payment, carried more of the mortgage, or paid for significant improvements like a new roof or kitchen, that partner may have a claim to a larger slice of the equity than the deed suggests. Courts in many jurisdictions recognize these unequal contributions. Documentation is what makes the claim real: bank statements, receipts, contractor invoices, and payment records from individual accounts.
Occupancy Credits
If you’ve already moved out and your partner has been living in the home alone, the arithmetic shifts in two directions at once. Under the majority rule in American property law, a co-owner who stays in a shared property doesn’t automatically owe rent to the one who left — unless the occupying owner actually prevented the other from returning, which the law calls ouster. Where ouster occurred, the non-occupying owner can claim their proportional share of fair market rent for the period of exclusion.
Running the other way: the occupying partner who has been covering property taxes, insurance, and necessary repairs alone can claim credit for the other owner’s share of those costs. All of these credits and debits get netted into the final buyout figure.
Married or Not: Why It Matters
Whether you and your partner are married changes the taxes, the mortgage rules, and the authority a court has over the outcome. This is the single biggest source of surprise in buyouts.
Tax Treatment
Transfers of property between spouses, or between former spouses as part of a divorce, are not treated as sales. Under Section 1041 of the Internal Revenue Code, no gain or loss is recognized, and the receiving spouse takes the original tax basis.2GovInfo. 26 USC 1041 – Transfers of Property Between Spouses or Incident to Divorce The transfer qualifies if it happens during the marriage, within a year of divorce, or is “related to the cessation of the marriage,” which courts read broadly to cover most divorce settlement transfers.
Unmarried co-owners get no such treatment. A buyout between unmarried partners is a sale, and capital gains tax may apply if the property has appreciated.
The Mortgage
Federal law prevents lenders from calling a mortgage due simply because ownership transfers to a spouse or child, or because a divorce decree awards the home to one spouse. The Garn-St. Germain Act bars enforcement of due-on-sale clauses in those situations.3Office of the Law Revision Counsel. 12 US Code 1701j-3 – Preemption of Due-on-Sale Prohibitions Unmarried partners have no such shield. A lender presented with a transfer between unmarried co-owners may invoke the due-on-sale clause and demand full repayment. Many don’t, but the risk is real and belongs in your planning.
Court Authority
In a divorce, a family court has broad power to divide property equitably and can order a buyout on terms different from what the deed says — adjusting shares based on income, length of marriage, and contributions. For unmarried co-owners, no family court is involved. The starting point is the deed, and disputes get resolved through contract law or, as a last resort, a partition action.
Taxes If You’re the One Being Bought Out
When Section 1041 doesn’t apply — which is to say, when you’re not married or divorcing — selling your share is a taxable event.
The Primary Residence Exclusion
If the home was your primary residence and you lived in it for at least two of the five years before the buyout, you can exclude up to $250,000 of capital gain from your income. Married couples filing jointly can exclude up to $500,000 if at least one spouse meets the ownership test and both meet the use test.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence For most homeowners that exclusion erases any capital gains liability.
There is a timing trap. If you moved out more than three years before the buyout closes, you no longer meet the two-out-of-five-year use requirement, and gain above your basis becomes taxable. If a buyout is likely, don’t let the clock run out. Gain above the exclusion gets reported on Schedule D; long-term capital gains rates for 2026 are 0%, 15%, or 20% depending on taxable income.5Internal Revenue Service.

Gift Tax If the Price Is Too Low
If your partner buys you out for materially less than your share is worth — out of generosity, exhaustion, or pressure to close quickly — the IRS may treat the shortfall as a gift from you to your partner. The 2026 annual gift tax exclusion is $19,000 per recipient.6Internal Revenue Service. Frequently Asked Questions on Gift Taxes If the gap between fair market value and the actual price exceeds that, you have to file Form 709.7Internal Revenue Service. Instructions for Form 709
Filing doesn’t necessarily mean owing. The 2026 lifetime estate and gift tax exemption is $15,000,000 per person, so the excess simply reduces that lifetime allowance.8Internal Revenue Service. What’s New – Estate and Gift Tax Still, missing the filing when it’s required creates problems later. The clean way to avoid the issue is to agree on a price that reflects genuine fair market value, backed by an appraisal.
Getting Your Name Off the Mortgage
If your name is on the mortgage, you remain personally liable for the debt no matter what a buyout agreement says between you and your partner. A signed buyout and a transferred deed don’t protect you if your partner stops making payments later. The mortgage has to be dealt with directly.
Refinancing
The cleanest path is for your partner to refinance into a loan in their own name, which pays off the existing mortgage and releases you from liability. Most conventional mortgages expect this when ownership changes hands.9Fannie Mae. Changing or Transferring Ownership of a Home Your partner has to qualify on their own credit and income. Refinancing closing costs typically run 2% to 6% of the loan amount, which should be factored into negotiations.
Assumption in a Divorce
In a divorce, refinancing isn’t the only route. The spouse keeping the home can sometimes assume the existing mortgage and request a release of liability for the departing spouse, preserving the current interest rate — which matters when rates have risen since the loan was originated. The remaining spouse still has to be credit-qualified by the servicer, and not every loan is assumable.9Fannie Mae. Changing or Transferring Ownership of a Home FHA and VA loans generally are; conventional fixed-rate loans typically are not, except in protected situations like divorce.
Liens and Title
Run a title search before you close. Unpaid taxes, contractor liens, and court judgments attached to the property need to be cleared, and a title company will flag them for a few hundred dollars. Skipping this step can leave you tangled with the property long after you thought you were done.
Put It in Writing
A handshake is not enough when a house is involved. The buyout agreement should be a written, signed contract covering, at minimum:
- The buyout price and how it was calculated, referencing the appraisal
- Payment timing — at closing, in installments, or contingent on refinancing
- Who pays the mortgage until refinancing closes, and what happens if refinancing is denied
- Any credits for unequal contributions to the down payment, mortgage, or improvements
- When the departing owner moves out and any rental credit owed
- The type of deed to be used and the deadline for recording it
- Consequences if either party fails to follow through
In a divorce, this agreement typically folds into the divorce decree or property settlement and carries the force of a court order. For unmarried co-owners, it’s a private contract enforceable in civil court. Either way, have an attorney review it before signing. Mistakes in buyout agreements surface months or years later, when fixing them costs much more than drafting them well.
Once the agreement is signed and the money changes hands, a new deed is prepared and recorded with the local land records office. A quitclaim deed — which transfers whatever interest you have without warranting a clean title — is the standard choice between people who already co-owned the property, since the buyer already knows its history. A warranty deed, standard in arm’s-length sales, includes a guarantee the title is free of liens. For most partner buyouts a quitclaim does the job. After recording, update property insurance, tax records, and any homeowner’s association accounts to show the new sole owner.
When You Can’t Reach a Deal
Not every buyout settles cleanly. The options escalate in cost and formality.
Mediation brings in a neutral third party to facilitate a compromise; the mediator doesn’t impose a decision. It’s cheaper than court and tends to preserve working relationships. Arbitration is a step up: an arbitrator hears both sides and issues a binding decision, usually final with limited grounds for appeal.
If your partner refuses to buy you out and you can’t agree on what to do with the property, you have the right to file a partition action — a lawsuit asking the court to physically divide the property (rare for a single-family home) or order it sold and the proceeds split. Any co-owner can file, even a minority owner, and courts generally treat the right as absolute, so a partner can’t block it by refusing to cooperate. Partition is a last resort for a reason: the property typically sells at auction, often for less than market value, and legal fees can be substantial. Both sides usually end up with less than a negotiated buyout would have delivered. The threat of partition is often what brings a reluctant partner back to the table.
Full litigation makes sense when the dispute involves contested ownership shares, fraud, or breach of an existing agreement. It’s slow, expensive, and unpredictable, and should come after mediation, arbitration, and negotiation have all failed.
Protecting Yourself Through the Process
The biggest risk in a buyout isn’t a bad appraisal or a high closing cost. It’s moving too fast under emotional pressure and leaving money or liability behind.
Don’t sign a deed transfer until the mortgage is resolved. Transferring ownership while your name stays on the loan gives up your leverage and keeps all your liability. Insist on refinancing or a formal release of liability before the deed changes hands.
Get your own appraisal. If your partner presents a valuation, don’t accept it on faith. A few hundred dollars is cheap insurance against undervaluing your share.
Watch the tax clock. If you’ve already moved out, track how long it’s been. Losing the $250,000 capital gains exclusion because the buyout dragged past the two-out-of-five-year window is expensive and entirely avoidable.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
Document everything. Every payment toward the mortgage, taxes, insurance, and improvements strengthens your position on the buyout amount. If the matter later reaches a mediator or court, receipts and bank records matter far more than memories.
