Co-Owner Won't Sell? Force a House Sale (2026 UK Guide)

By Lisa Hayes · 10 August 2026

If you jointly own a house and the other owner won't sell, you cannot simply put it on the market and pocket your share — but you're far from stuck. You can sever a joint tenancy on your own, negotiate a buyout, sell your own beneficial share, or, as a last resort, ask a court to force the sale under Section 14 of the Trusts of Land and Appointment of Trustees Act 1996. Most of these disputes settle long before a judge gets involved, and the smart move is almost always to make a credible threat of court while keeping the door open to a deal.

This comes up more than people think. An ex you're no longer speaking to. A brother who inherited half the family home and treats it like a shrine. A friend you bought a flat with in your twenties, now living three hundred miles away. The property is worth real money and one of you is trapped. Here's exactly how to get unstuck, what each route actually costs, and where people talk themselves into an expensive mistake.

What does it actually mean when a co-owner won't sell?

When two or more people own a property together in England or Wales, the law splits ownership into two layers. There's the legal title — the names on the Land Registry, the people who can sign a transfer — and there's the beneficial interest, which is who actually owns the money tied up in the bricks. Usually the same people hold both. But not always, and that distinction is the hinge everything else turns on.

A property can only be sold if everyone on the legal title signs. That's why one refusing owner can bring the whole thing to a halt: a conveyancer cannot complete a sale with a missing signature. What they cannot do, though, is stop you from taking steps to realise your share. That's the leverage most people don't realise they have.

First, work out how you own it: joint tenants or tenants in common?

Before you do anything else, find out how the property is held. It changes your options completely, and plenty of people get it wrong. There are two ways to co-own in England and Wales.

Check your title register — a copy costs a few pounds from HM Land Registry. If there's a "Form A restriction" on the proprietorship register, you're tenants in common. No restriction usually means joint tenants. If you inherited the place, you're almost certainly tenants in common. Know which one applies before you spend money on solicitors.

What are your options if a joint owner won't sell?

You have more routes than the classic "take them to court" that everyone jumps to. Run through them roughly in this order — cheapest and least hostile first.

1. Talk, then mediate. Unglamorous, but it works. A single session with a property or family mediator costs a fraction of litigation and settles a huge share of these disputes. Since the civil rules tightened in October 2024, courts increasingly expect you to have tried mediation, and a judge can penalise you on costs if you refused a reasonable offer to mediate. So it's not just the decent thing to do — dodging it can cost you money later.

2. One of you buys the other out. If the reluctant owner wants to keep the house, the clean solution is for them to buy your share at its current market value. Get a proper valuation first so the number is defensible, not a figure plucked from a portal. The catch: they usually need a mortgage or savings to fund it, and if they can't raise the money, a buyout is a fantasy and you're back to selling.

3. Sell your share, not the whole house. Less well known, but real. If you're tenants in common, your beneficial share is an asset you can sell — to the other owner, or in some cases to a specialist buyer. It rarely fetches full pro-rata value because whoever buys inherits the dispute, but it can be the fastest way to get money out and walk away.

4. Sever the joint tenancy. If you're joint tenants, this is often the first formal move. It converts your ownership to tenants in common so you each hold a defined share. It doesn't force a sale, but it protects what's yours (see below).

5. Apply for an order for sale under TOLATA. The nuclear option, and the one that gives every other route its teeth. If nothing else lands, you ask the court to order the property sold. More on exactly how that works further down.

How do you sever a joint tenancy — and should you?

Severance is one of the most useful and least understood tools in this whole area. If you own as joint tenants and things have gone sour, severing converts the ownership to tenants in common. Do it, and your share stops passing automatically to the other owner if you die — it goes wherever your will says instead. If you're in a bitter split and you're still joint tenants, this matters enormously: die before it's resolved and your ex could inherit your half by survivorship.

Here's the part people find surprising: you can do it on your own, without the other owner's agreement. Under Section 36 of the Law of Property Act 1925 you serve a written "notice of severance" on the other owner. If they refuse to sign or engage, you post it by recorded delivery to their last known address and keep proof — Section 196 of the same Act treats that as valid service even if they never open it. You then send Form SEV to HM Land Registry (with the notice, or a certified copy) to enter the Form A restriction.

Be clear about what severance does and doesn't do. It protects your share. It does not, by itself, force a sale or hand you any cash. Think of it as putting a lock on your half while you sort out the bigger fight.

How do you force a sale? The TOLATA order for sale explained

When every reasonable attempt to agree has failed, you apply to the court for an order for sale under Section 14 of the Trusts of Land and Appointment of Trustees Act 1996 — TOLATA, as everyone shortens it. The Act says that any trustee of the land (a legal owner) or anyone with a beneficial interest in it can apply to the court for an order relating to the property. That deliberately wide wording is why the route is open to unmarried partners, siblings, friends and business co-owners alike.

Where the only real argument is whether the house should be sold, the claim usually goes through the Part 8 procedure under the Civil Procedure Rules — the streamlined track for disputes that turn on a point rather than a mess of contested facts. If you're also arguing about who owns what share, expect a longer, more involved Part 7 claim with witness statements and disclosure.

The judge won't rubber-stamp a sale. The court has genuine discretion here, and it weighs a specific set of factors before deciding. Which brings us to Section 15.

What will the court actually consider? The Section 15 factors

Section 15 of TOLATA sets out what a court weighs when it decides whether to order a sale. There's no hierarchy — no single factor automatically wins. The court looks at the whole picture, including:

• The intentions of the people who set up the trust. Why did you buy it together in the first place — as a home, an investment, a stopgap?
• The purpose the property is held for. If that purpose still exists (say, housing a child), the court may lean against a sale, at least for now.
• The welfare of any minor who occupies the property, or might reasonably be expected to. Children in the home carry real weight.
• The interests of any secured creditor — for example a lender with a charge, or someone who has secured a debt against an owner's share.

In practice, where a relationship has ended and there are no children living there, courts are usually willing to order a sale — the shared purpose that justified joint ownership has gone. Where a child still lives in the property, a judge may postpone a sale until, say, they finish school. Every case turns on its facts, and this is exactly where good legal advice earns its fee.

How long does a TOLATA claim take, and what does it cost?

This is the part that should make you try everything else first. Issuing the claim is cheap. Fighting it to the end is not.

• £308court fee to issue a Part 8 claim (2025/26 rate)
• 12 months+typical time to a final hearing if it goes the distance
• £10k-£50k+legal costs per side when a case runs to trial

The issue fee is a few hundred pounds. But add solicitors, a barrister, possibly an expert on the property or the shares, and the interim and hearing fees, and a fully contested TOLATA trial can cost each side well into five figures. And costs generally "follow the event" — the loser usually pays a significant slice of the winner's bill on top of their own. Lose a fight over a £250,000 house and the legal costs can eat a frightening share of your equity.

That maths is the whole reason the threat of a TOLATA claim is so effective. A reluctant owner who's told "sell, or I'll issue proceedings and you may end up paying both sides' costs" tends to rediscover their willingness to negotiate. Court is the stick. The deal is the goal.

The mistakes that cost people the most

I've watched the same avoidable errors play out again and again. Steer clear of these.

Moving out and assuming you've given up your claim. You haven't. Leaving the property doesn't forfeit your beneficial share. But do get advice about "occupation rent" — where one owner stays and the other is excluded, the court can sometimes credit the absent owner for the other's sole occupation.

Stopping mortgage payments to force the issue. Tempting, disastrous. You'll wreck your own credit file and hand the lender a reason to repossess, and a forced sale by the lender rarely gets anyone a good price. If repossession is looming, deal with that first.

Emptying the joint account or changing the locks. Petty acts of war read badly to a judge and can hurt you on costs. Behave as though everything you do will be read out in court, because it might be.

Refusing to mediate on principle. Since October 2024 the courts take a dim view of parties who won't even try. Turning down a reasonable offer to mediate can cost you when the judge decides who pays.

Dragging it out to punish the other person. The property still has to be sold at the end. All you buy with delay is more legal cost and a lower share of what's left.

Special situations that change the game

You inherited the house with siblings and one won't sell

Extremely common, and rarely really about money — it's grief, memory and old family scores. Legally, if you inherited jointly you're almost certainly tenants in common, so each of you owns a defined share and can push for a sale. The knot is usually one sibling living in the property. They can't be forced out overnight, but the others aren't obliged to fund their rent-free stay indefinitely, and occupation rent may come into play. If you're going in circles, our guide to selling an inherited property walks through the practicalities, and it's worth reading alongside whether you can sell before probate is granted.

You're an unmarried couple splitting up

If you weren't married or in a civil partnership, you have no divorce-style claim over each other's assets — the "common law marriage" is a myth, full stop. Your rights over the house rest on property law: your legal title and your beneficial share, sorted out through TOLATA if you can't agree. That's a very different landscape from a married split, where the family courts divide assets more broadly. If you were married, read our separate guide to selling a house during divorce instead — the rules are not the same.

The other owner has gone missing or won't respond

Silence isn't a veto. If a co-owner has vanished or simply ignores every letter, you're not powerless. Severance still works — recorded delivery to their last known address counts as valid service even if they never reply. And a TOLATA claim can proceed against an owner who won't engage; the court can make orders where a party fails to respond, and can authorise a sale and deal with their share of the proceeds. Keep meticulous records of every attempt you make to contact them, because a judge will want to see that you tried properly before asking the court to act around them.

One owner is bankrupt

If a co-owner goes bankrupt, their share vests in a trustee in bankruptcy, whose job is to realise it for the creditors. That trustee can themselves apply for an order for sale, and after a year the court generally gives the creditors' interests priority unless the circumstances are exceptional. If that's your situation, get specialist advice fast — the timelines and rules are their own thing.

Is there a faster, cheaper way out?

Yes — and for a lot of people it's the sensible answer once the initial anger cools. If your real goal is to release your money and move on rather than to win, litigation is usually the worst value route on the table. Two calmer options:

Sell your beneficial share. If you're tenants in common and just want out, you may be able to sell your share to the other owner or, in some cases, a specialist buyer. You'll take a discount, but you skip the year-long fight and the legal bills that come with it.

Agree a quick sale of the whole property. Once both owners accept the house is going, the argument shifts from whether to how fast. A genuine cash buyer can complete in weeks rather than months, which appeals when two people are desperate to sever ties. Sale prices from these buyers sit below full open-market value, so weigh the speed against the discount — but for a stalemate that's been dragging on, certainty and speed can be worth a great deal. Our rundown of how cash house buyers work and the best house-buying companies will tell you what's realistic, and if you just need it gone, selling your house fast lays out the trade-offs honestly.

The honest bottom line

A co-owner refusing to sell feels like a dead end. It isn't. You have a clear ladder of options — mediate, buy out, sell your share, sever the joint tenancy, and, if it comes to it, force a sale under Section 14 of TOLATA. The law is squarely on the side of an owner who wants to realise their share; nobody can trap your money in a house forever. The only real questions are how much you're willing to spend, how long you're willing to wait, and whether you'd rather keep control by agreeing a deal or hand the decision to a judge.

My advice, after seeing plenty of these: get your title checked, get a defensible valuation, take one hour of proper legal advice early, and use the threat of court to drive a settlement rather than marching straight into a two-year war. In most cases the fastest way through is a clean sale you both sign up to — and you're closer to that than the deadlock makes it feel.

If you and your co-owner are ready to move, the quickest way to see what the house is worth and what a fast sale could look like is to compare offers with a free, no-obligation valuation. No pressure, no tie-in — just a realistic number to build your decision around.
