When a sibling won’t sell inherited property, the other co-owners are not stuck. You can negotiate a buyout, try mediation, sell your own fractional share, or file a partition lawsuit that asks a court to order the sale. The sibling who wants to hold on cannot veto any of this. What they can do is make the process slower and more expensive, which is why the cheapest options are worth exhausting before you file anything.
What You Actually Own
Unless the will or trust says otherwise, siblings who inherit a home take it as tenants in common. Each of you holds a separate fractional interest in the whole property. Three siblings, three equal one-third shares. Those shares are undivided, meaning every co-owner has the legal right to access and use the entire home. No one can lock the others out without legal consequences.
Each co-owner can also sell, mortgage, or transfer their individual share without the others’ permission. You can legally sell your one-third interest to a stranger, but almost no one wants to buy a fractional share of a house they’d co-own with hostile relatives, and the few investors who do demand steep discounts of 30% to 50% off the proportional value. The right matters more as leverage than as a real exit: letting the holdout sibling know you’re prepared to bring in an outside buyer sometimes moves them toward a fair buyout.
Start with a Buyout
The fastest and cheapest resolution is almost always a private buyout. Either the sibling living in the home purchases the other shares to keep it, or the siblings who want to sell purchase the resident’s share so the house can go on the market.
Get a professional appraisal first. Don’t agree on a price before the number comes back, and don’t skip hiring a real estate attorney to draft the buyout agreement and record the new deed. On a $600,000 home with no mortgage, each one-third interest is worth $200,000, and a handshake deal over that kind of money tends to produce a lawsuit later.
Paying for It
Few people have six figures in cash available. The most common route is a cash-out refinance by the buying sibling, who takes out a new mortgage on the property and uses the proceeds to pay off the others. Because the buyer already owns a fractional share, the built-in equity usually makes qualifying easier than a standard purchase.
When the estate holds other assets, siblings can offset values instead: one takes the house, another takes an equivalent amount in cash, investments, or other property. Installment payments between siblings are possible but require a written agreement and real trust. Expect closing costs and attorney fees of several thousand dollars whatever structure you use.
Try Mediation Before Court
If buyout talks stall, a professional mediator is worth the attempt before anyone files a lawsuit. The mediator is neutral, doesn’t impose a decision, and helps both sides see what a court fight actually costs. Most sessions wrap up in a day or two.
Mediation tends to preserve family relationships better than a judge ordering a sale over someone’s objection, because any agreement is one both sides helped shape. If it fails, nothing said during the process can be used against you in court, so the downside is small.
Filing a Partition Action
When negotiation runs out, any co-owner can file a partition action: a lawsuit asking a court to end the co-ownership. Courts grant these because the law doesn’t trap anyone in a shared investment indefinitely. The sibling who refuses to sell cannot defeat the case by objecting to it.
Two outcomes are possible. A partition in kind physically splits the property among the owners, but courts rarely do this with a single-family home since a house doesn’t divide into useful parcels. The common result is partition by sale: the court orders the property sold and the proceeds divided.
How the Case Moves
You file in the court where the property sits, name all co-owners, and serve each one with the lawsuit. After confirming ownership percentages, the court issues a judgment ordering partition and typically appoints a neutral referee or commissioner to run the sale. The referee hires the agent, lists the property, reviews offers, and closes. Sale expenses and referee fees come out of the proceeds before anyone receives a share, generally split by ownership percentage, though courts can shift more of the cost onto a sibling who was uncooperative.
Time and Money
A straightforward partition takes six to twelve months from filing to final distribution. Cases with title problems, hard-to-locate siblings, or active obstruction can stretch past 18 months. Legal fees start around $5,000 to $10,000 for a simple matter and run to $30,000 or more when the other side fights every step. Add filing fees, the referee’s compensation, real estate commissions, and closing costs, and the total can consume a meaningful chunk of the proceeds. That math is the main reason to exhaust buyouts and mediation first.
Lis Pendens
When the partition suit is filed, the plaintiff typically records a lis pendens, a public notice that the property is in active litigation. It doesn’t technically block a sale or refinance, but title insurers refuse to issue policies on properties with pending litigation, and buyers won’t close without one. Anyone who does buy an interest after the lis pendens is recorded takes it subject to whatever the court decides.
Protections for Inherited Homes Under the Uniform Partition of Heirs Property Act
More than half the states and the District of Columbia have adopted the Uniform Partition of Heirs Property Act, which changes how a partition sale works when the property was inherited. If your state’s version applies, the court orders a professional appraisal to establish fair market value, and any co-owner who wants to keep the home gets a right of first refusal: they can buy out the sellers’ interests at the appraised value, typically within 45 days of notice. If no one takes that option, the court orders a sale on the open market at a commercially reasonable price rather than a courthouse auction.
Not every state has adopted the act, and provisions vary. Confirm whether your state’s version covers your property before counting on these protections.
How the Proceeds Get Divided
After a court-ordered sale, the money isn’t simply split by percentage. The court runs a final accounting that adjusts each sibling’s share based on who paid what during the co-ownership period. Record-keeping is where this is won or lost.
Credits for What You Paid
A sibling who covered more than their proportional share of carrying costs gets credit from the proceeds. Qualifying expenses include property taxes, homeowner’s insurance, mortgage payments, and repairs that preserved or increased value. Pay $15,000 in taxes that should have been split three ways, and you’d receive a $10,000 credit for the two-thirds your siblings should have covered before the remaining proceeds are divided.
Keep every receipt, bank statement, and cancelled check. Courts won’t credit expenses you can’t document. Cosmetic upgrades that mainly benefited the occupying sibling generally don’t qualify the way structural repairs and essential maintenance do.
Rent Owed by the Occupying Sibling
The sibling living in the home may owe the others for its fair rental value. This offset applies when the occupying sibling committed an “ouster”: effectively excluding the other co-owners from the property. Changing the locks, refusing access, filing a restraining order that forced a sibling out, or making clear through words and conduct that the other owners weren’t welcome can all count.
Courts weigh the nature of the exclusion, how long it lasted, and the intent. If ouster is established, the court calculates what the home would have rented for during the period of exclusive occupation and deducts that amount from the occupying sibling’s share. On a property with a fair market rent of $2,500 a month, three years of exclusive occupation translates to a $90,000 offset. This is one of the largest adjustments in partition cases, and occupying siblings often don’t see it coming.
Taxes on the Sale
Inherited property gets a stepped-up basis, one of the most valuable provisions in the federal tax code. When you inherit, your basis in the property resets to its fair market value on the date the owner died, not what they originally paid.1Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent
If a parent bought the home in 1985 for $80,000 and it was worth $500,000 on the date of death, your basis is $500,000. Sell for $520,000 and your taxable gain is $20,000, not $440,000. Sell quickly after inheriting and you may owe little or nothing. The longer you hold, the more any new appreciation stacks up as a taxable gain.
2026 Capital Gains Rates
Inherited property qualifies for long-term capital gains rates no matter how briefly you held it. For 2026, the federal rates are:2Tax Foundation. 2026 Tax Brackets and Federal Income Tax Rates
- 0% on taxable income up to $49,450 (single) or $98,900 (married filing jointly)
- 15% above those thresholds up to $545,500 (single) or $613,700 (joint)
- 20% above $545,500 (single) or $613,700 (joint)
Heirs who sell soon after the owner’s death often find the stepped-up basis wipes out most or all of the gain. Run the numbers before assuming you owe nothing, especially if the home has appreciated since the date of death or you have substantial other income.
If One Sibling Lived in the Home
The sibling who was living there may qualify for an additional break. Under Section 121, you can exclude up to $250,000 of capital gain ($500,000 for married couples filing jointly) from the sale of your principal residence if you owned and lived in it for at least two of the five years before the sale.3Office of the Law Revision Counsel. 26 U.S. Code 121 – Exclusion of Gain From Sale of Principal Residence Paired with the stepped-up basis, the resident sibling’s share of the proceeds can come out entirely tax-free. The siblings who didn’t live there cannot claim this exclusion on their shares.
Reporting It
The closing agent or title company reports the sale to the IRS on Form 1099-S, and each sibling gets a copy showing their share.4Internal Revenue Service.

An unreported 1099-S is one of the IRS’s automatic audit flags, so don’t skip it even when your gain works out to zero.
