What Happens to the Family Home When Both Parents Die UK (2026)?

What happens on the first parent's death depends entirely on how the property is legally owned: (1) Joint tenants (the most common ownership for a married couple): the survivorship rule (ius accrescendi) applies automatically. The deceased parent's 'share' of the property passes instantly and automatically to the surviving parent — outside probate, outside the will, without any legal formality. No grant of probate is needed to transfer the property. The Land Registry title is updated by lodging Form DJP (death of joint proprietor) with an official copy of the death certificate — a simple administrative step. The surviving parent now owns the property 100% solely; (2) Tenants in common: the survivorship rule does NOT apply. Each parent owns a defined share (typically 50/50, but it can be any split). The deceased parent's share passes under their will (or intestacy if there is no will). The surviving parent already owns their share — the deceased's share must go through probate. For a married couple, the deceased's share typically passes to the surviving spouse under the will or intestacy rules — free of IHT under the spouse exemption (IHTA 1984 s.18). The Land Registry title is updated by lodging an AS1 assent once probate is obtained; (3) Sole ownership: if only one parent owned the property, the survivorship rule cannot apply — the property passes under the will or intestacy and must go through probate. The surviving parent may inherit under the will or be granted a life interest in the property; (4) IHT on first death: transfers between spouses and civil partners are fully exempt from IHT (IHTA 1984 s.18), regardless of the value of the estate. The nil-rate band (£325,000) and residence nil-rate band (£175,000) unused on the first death are transferred to the surviving spouse — to be used on the second death.

When the last parent dies, the family home is now solely owned by their estate and must pass through the administration process: (1) Probate is required: the property cannot be sold or transferred to the children until a grant of probate (if there is a will) or letters of administration (if no will) is obtained. This is true regardless of the property's value — there is no small estate exemption for property; (2) The property passes under the will or intestacy: the surviving parent's will should specify what happens to the property — specific gift to named children, sold and divided, or left as part of the residuary estate to be divided equally. If there is no will, the property passes under the Administration of Estates Act 1925 intestacy rules (to the children equally if no spouse survives); (3) CGT re-basing: the children inherit the property at the date-of-death probate value — the open market value at the date of death. Any increase in value during the deceased's ownership is permanently exempt from CGT (the 'death re-basing' rule). CGT is only relevant if the children later sell for more than the probate value; (4) Vacant possession: if the property was the parents' home, it will be vacant after the last parent's death (subject to any tenants or occupiers — see also the position of adult children still living there, discussed below). The executor is responsible for insuring and maintaining the property pending sale or transfer; (5) Assent to children: if the children are to keep the property, the executor executes an AS1 assent (for registered land) transferring the title from the estate to the beneficiaries. This does not attract SDLT (Finance Act 2003 Sch 3 para 3A). Land Registry registration of the assent may attract a registration fee.

The second death is where IHT is most carefully calculated, as both the transferable nil-rate band and the residence nil-rate band can be claimed: (1) Transferable nil-rate band (TNRB): if the first parent to die did not use their nil-rate band (or used less than the full amount — for example, by leaving a small gift to a sibling), the unused percentage is transferred to the surviving spouse and added to their NRB on death. For most married couples, both nil-rate bands are available on the second death: 2 × £325,000 = £650,000; (2) Residence nil-rate band (RNRB) and transferable RNRB: the RNRB (£175,000 per person in 2026/27) applies where the family home (or former home) is closely inherited by lineal descendants (children, grandchildren). If the first parent's RNRB was fully or partly unused, the unused percentage transfers to the second death estate. For most couples, 2 × £175,000 = £350,000 RNRB is available on second death; (3) Combined threshold (2026/27): for a married couple where all allowances transfer, the second death estate can be shielded up to: £325,000 (NRB) + £325,000 (transferred NRB) + £175,000 (RNRB) + £175,000 (transferred RNRB) = £1,000,000 tax-free threshold (provided the estate does not exceed £2 million — above which the RNRB tapers at £1 for every £2 above the threshold); (4) Qualifying conditions for RNRB: the property must have been the deceased's residence at some point during their ownership; it must be closely inherited (directly to children, grandchildren, step-children, adopted children); it must pass outright or via a direct descendant's trust; (5) IHT rate: 40% on the taxable estate above the combined thresholds (or 36% if 10% or more of the net estate is left to charity).

An adult child living in the family home at the time of both parents' death occupies a legally uncertain position: (1) No automatic right to stay: an adult child living in the parents' home (rent-free, as a licensee) has no automatic legal right to remain after the parents' deaths. Their right of occupation is a bare licence from the parents — it terminates on the parents' death. The executor takes over responsibility for the property and can require the occupant to leave; (2) Executor's duty to administer: the executor is under a duty to administer the estate for all beneficiaries. If the will leaves the property equally to multiple children, the executor must realise the value — usually by sale — for all beneficiaries equally. An occupying beneficiary cannot unilaterally refuse a sale; (3) TOLATA 1996 application for sale: if the property is held on a trust (e.g., the children inherit as tenants in common), any beneficiary with a half-share can apply to the court under Trusts of Land and Appointment of Trustees Act 1996 s.14 for an order for sale. The court will generally order sale unless the remaining beneficiaries have a compelling reason (such as having minor children resident); (4) Beneficial interest claim: if the adult child has contributed to the purchase price, mortgage payments, or improvement of the property, they may have a beneficial interest under a constructive trust (Stack v Dowden [2007]). This claim must be resolved before the property is sold; (5) Occupation rent: if one beneficiary has been living in the property rent-free during the estate administration, the other beneficiaries may be entitled to an occupation rent (TA 1925 s.12 and TOLATA 1996 s.13). This is a practical negotiation point; (6) The will can address this: the parents can grant a specific right of occupation (life interest) in the will to the resident child — this protects the child while preserving the others' eventual inheritance.

No — a transfer of property by way of assent (i.e., to a beneficiary under a will or intestacy) is exempt from Stamp Duty Land Tax (SDLT): (1) The SDLT exemption for assents: Finance Act 2003 Schedule 3 paragraph 3A exempts the transfer of land or buildings to a person entitled under the will or intestacy of a deceased person. This means the AS1 assent from the executor to the inheriting children is not a chargeable transaction and no SDLT return is required (or only a nil return); (2) What is NOT exempt — purchasing the deceased's share: if one of the children wants to buy out the other children's shares (so they can own the property solely rather than as tenants in common), that is a purchase — not an assent — and SDLT applies on the consideration paid. If the buying sibling already owns a residential property, the 3% SDLT surcharge may also apply; (3) CGT on later sale: SDLT is a one-time transaction tax paid on purchase. CGT is a different tax on the gain when the children later sell the property. The children's CGT base cost is the probate value — not the original cost to the parents. Any gain above the probate value is potentially chargeable at 18% or 24% (depending on the beneficiary's tax position). If the inheriting child lives in the property as their main residence, principal private residence relief (PPR) reduces or eliminates the CGT. Children who already own their own main residence and inherit a second property will face CGT (and the 3% SDLT surcharge if they later purchase) unless they move in; (4) Land Registry fees: registering the AS1 assent at the Land Registry attracts the scale registration fee (based on property value). For a £500,000 property, this is £910.
