Selling an Inherited House with Siblings

Inheriting a property with siblings is one of the more complex situations a family can face. Even where relationships are good, the decision of what to do with the house — sell it, keep it, or have one sibling buy out the others — involves significant money, competing needs, and often a great deal of emotion. Where relationships are strained, or where one sibling has different financial circumstances to the others, disagreements can quickly escalate into legal disputes that are costly for everyone involved.

This guide explains the legal framework for co-inherited property in England and Wales, the options available when siblings disagree, and the practical steps you can take to get to a resolution — ideally without going to court. For the probate process itself, see our guide on selling a house after probate. For a broader overview of inheriting and selling a property, see selling a house you inherited.

How property passes to siblings: wills and intestacy

The starting point is to understand how the property came to be owned by siblings in the first place, because this determines who owns what share.

Inheritance under a will

If the deceased left a valid will, the property passes in accordance with its terms. A parent might leave the family home equally to two or three children, or in unequal shares — for example, leaving a larger portion to a child who acted as a carer. The will is the authoritative document, and siblings inherit in the proportions it specifies.

If the property was left to a sibling who has since died, their share will pass through their own estate (unless the will contains a substitution clause directing where that share should go instead). If there is no substitution clause and the beneficiary predeceased the testator, the gift may lapse and fall into the residue of the estate.

Inheritance under intestacy

If the deceased left no valid will, the property passes under the rules of intestacy set out in the Administration of Estates Act 1925. The key rules are:

Under intestacy, each child or sibling inherits an equal share by default. There is no provision for unequal shares based on a particular child's relationship with the deceased or any informal promises made during the deceased's lifetime. Disputes about informal promises or detrimental reliance may give rise to claims under proprietary estoppel, but these require separate legal proceedings.

The legal framework: trust of land under TOLATA 1996

When property passes to two or more siblings, it is held on a trust of land under the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA). The legal title is held by the trustees (typically the executors or the siblings themselves once the property is transferred to them), and the beneficial interests — the economic rights to the proceeds — belong to the beneficiaries in their respective shares.

TOLATA replaced the old "trust for sale" regime and gives the court much wider discretion in resolving disputes about co-owned property. The key provisions are:

• Section 12 — gives beneficiaries with an interest in possession a right to occupy the property, subject to certain conditions
• Section 13 — allows the trustees to restrict or exclude a beneficiary's right of occupation and to impose conditions, including paying an occupation rent to excluded co-owners
• Section 14 — allows any person with an interest in the trust to apply to the court for an order, including an order for sale
• Section 15 — sets out the factors the court must consider when making an order under Section 14, including the intentions behind the trust, its purpose, the welfare of any minor occupants, and the interests of secured creditors

For more detail on the court's powers to order a sale, see our guide on forced sale of property.

Executor's role when siblings disagree

Until the property is transferred to the beneficiaries by way of an assent (form AS1), it remains under the control of the executor. The executor has a fiduciary duty to act in the best interests of all beneficiaries and cannot simply side with one sibling against another.

Where siblings disagree, the executor's obligations include:

• Keeping all beneficiaries equally informed about the estate and the property's status
• Not accepting offers or signing contracts without proper authority (which, in a contested situation, may require court directions)
• Maintaining and insuring the property while the dispute is resolved, so the estate is not prejudiced by delay
• Applying to the court for directions if the dispute cannot be resolved and the estate administration is being held up

If the executor is one of the disputing siblings, the conflict of interest can be acute. In these circumstances, it may be appropriate for that executor to seek independent legal advice, or for the beneficiaries to consider whether a neutral professional executor should be appointed. For more on the executor's duties in a disputed situation, see our guide on selling property as an executor of an estate.

Options when siblings cannot agree

When siblings cannot reach agreement on what to do with an inherited property, the practical options are:

1. Mediation

Mediation is almost always the right first step. A mediator — typically a solicitor or barrister with specialist experience in property and estates disputes — facilitates a structured negotiation. Mediation is significantly cheaper than court proceedings (costs are typically in the hundreds rather than thousands of pounds per party), quicker, and private. Outcomes can be more tailored than anything a court would impose, including arrangements such as a phased sale, a rental period, or a deferred buyout.

Many courts now expect parties to have attempted mediation before issuing TOLATA proceedings. Refusing to mediate without good reason can be penalised in costs even if you ultimately win at court.

2. One sibling buys out the others

Where one sibling wants to keep the property, they can buy out the others at market value. This requires:

• An independent valuation from a RICS-qualified surveyor to establish the open market value (both the buying and selling siblings should ideally commission separate valuations, or agree on a single joint instruction)
• Agreement on the price, which should reflect the full market value of each sibling's share
• Finance for the buying sibling, who will usually need a mortgage if they do not have sufficient cash. The mortgage lender will conduct their own valuation
• Legal conveyancing to transfer the shares — each sibling should have independent legal advice

For SDLT purposes, the consideration paid is the price for each sibling's share. If the buying sibling already owns another residential property, the higher rate SDLT surcharge (currently 5% above the standard rates) may apply.

3. Sell the property on the open market and divide the proceeds

The simplest solution in most cases is to sell the property on the open market and distribute the net proceeds in accordance with each sibling's share. This gives a clean break with no ongoing entanglement between the siblings, and the proceeds are objectively determined by what a buyer is willing to pay.

4. Keep the property and let it as a rental

Where all siblings agree, they can keep the property as an investment and let it to tenants. This requires a formal co-ownership agreement covering management responsibilities, how rental income is split, what happens if one sibling wants to sell their share, and how decisions are made. Without a formal agreement, disputes are almost inevitable over time.

5. Court application under Section 14 TOLATA

If mediation fails and no consensual solution can be reached, any sibling with a beneficial interest can apply to the county court or the High Court under Section 14 of TOLATA for an order compelling a sale. The court will consider the Section 15 factors and, in the case of an inherited property with no special circumstances (such as dependent children in occupation), will usually grant a sale order. Court proceedings should be a last resort — costs can run to tens of thousands of pounds in contested cases, and the relationship damage is often permanent.

When one sibling is living in the inherited property

This is one of the most contentious situations in sibling inheritance disputes. A sibling who is occupying the property — whether they moved in to care for the parent, lived there before the death, or moved in afterwards — has certain rights under TOLATA but those rights are not unlimited.

Right of occupation

Under Section 12 of TOLATA 1996, a beneficiary who is entitled to a beneficial interest in the property has a right to occupy it if:

• The purposes of the trust include making the property available for occupation, and
• The property is suitable for occupation by that beneficiary

In practice, inherited family homes will usually satisfy both conditions, meaning a sibling who moves in or stays in the property has a legal basis for occupation that cannot simply be overridden by the other siblings.

Occupation rent

Where one sibling is in occupation and the others are not, the trustees (or the court, if the matter goes to litigation) can require the occupying sibling to pay an occupation rent to the excluded co-owners under Section 13 of TOLATA. The occupation rent is calculated by reference to the fair market rental value of the property, apportioned according to each co-owner's share.

For example, if a property has a rental value of £1,500 per month and is owned equally by three siblings, the occupying sibling 'owes' each excluded sibling £500 per month. The occupying sibling's own share (£500) offsets against this, so the net liability to the other two is £1,000 per month in total.

Compelling a sale when a sibling refuses to leave

The other siblings can apply to the court under Section 14 of TOLATA for a sale order and, if the court grants it, a vacant possession order. The court will consider the Section 15 factors, including the welfare of any children in occupation. Where the occupying sibling has no dependent children and there are no exceptional circumstances, the court will generally grant the sale order, though it may allow a reasonable period for the occupying sibling to vacate.

Capital gains tax when siblings sell an inherited house

Each sibling is treated as a separate taxpayer for capital gains tax purposes. The gain attributable to each sibling is calculated individually and each person uses their own CGT annual exempt amount. This is one of the significant tax advantages of inherited property passing to multiple beneficiaries: the gain is fragmented between them.

The calculation for each sibling is:

CGT on UK residential property must be reported and paid within 60 days of completion using HMRC's Capital Gains Tax on UK Property online service. Each sibling submits their own report and payment separately. Missing the 60-day deadline incurs an automatic penalty.

For a detailed breakdown of how CGT applies to inherited property, including private residence relief and worked examples, see our guide on capital gains tax on inherited property.

Equal vs unequal shares: what the numbers look like

Understanding how the proceeds are calculated helps prevent disputes at the point of sale. The following example illustrates how the split works for three siblings inheriting in equal shares.

In this example, each sibling receives £147,600 net before CGT, with a CGT liability of £1,104 each at the higher rate. Basic-rate taxpayers would pay £828 each (18%). Note that where a sibling's gain, when added to their income, straddles the basic and higher rate bands, the gain is taxed proportionately at each rate.

Practical steps to minimise disputes

Most sibling inheritance disputes do not arise from bad faith — they arise from a lack of process, unclear roles, and unspoken assumptions. The following practical steps can help keep the sale on track:

1. Agree a decision-making process early. At the outset, agree how decisions will be made: by unanimous consent, by majority, or with a casting vote. Put this in writing so there is no ambiguity later.
2. Instruct a neutral solicitor. Rather than each sibling instructing their own solicitor for the estate administration, instructing one firm to act for the estate (not any individual sibling) keeps the process cleaner and cheaper. Each sibling can, and should, take their own independent legal advice on their personal position.
3. Get an independent valuation before any negotiations. Disputes about price are much easier to resolve when there is an objective valuation from a RICS-qualified surveyor that all parties accept as a reference point.
4. Keep the property insured and maintained throughout. An unoccupied property is a liability. All siblings should agree who is responsible for insurance, council tax, utilities, and maintenance costs, and how those costs are apportioned.
5. Use a formal account for all expenditure. Keep a clear record of every cost incurred on the property. Disputes about who paid what are common and entirely avoidable with basic financial record-keeping.
6. Set a decision deadline. Open-ended discussions can drift for years. Agreeing that a decision will be made by a specific date focuses minds and reduces procrastination.
7. Try mediation before litigation. Even where relationships have broken down, mediation is faster, cheaper, and less destructive than TOLATA proceedings. Courts expect it to have been attempted.

How long does the process take?

Where siblings agree, the timeline for selling an inherited property follows the standard probate sale process: typically six to twelve months from death to completion, depending on the complexity of the estate and the conveyancing. For a detailed breakdown of the conveyancing stage, see our guide on how long conveyancing takes.

Where there is a dispute, each additional layer adds time:

The costs of litigation in a contested TOLATA case can easily exceed £20,000 to £50,000 per party in a High Court dispute, and there is no guarantee of a costs order in your favour even if you win. This is why reaching agreement — or at minimum a mediated settlement — is almost always in every sibling's financial interest.
