Missing Beneficiaries and Unknown Heirs: Managing Probate Risks
When someone agrees to act as an executor, they rarely expect the hardest part of the job to be finding the people who are supposed to inherit. Yet it happens often. A sibling emigrated in the 1970s and contact faded. A will leaves a share to "my grandchildren" and nobody is certain how many there are. Someone dies without a will, and the nearest surviving relatives turn out to be cousins nobody has ever met.
These situations are more than an inconvenience. Personal representatives, meaning executors appointed by a will or administrators appointed on an intestacy, are personally liable if they distribute an estate to the wrong people. If a beneficiary emerges later and their share has already been paid out to somebody else, the personal representative can be required to make good the shortfall from their own pocket. Good faith is not, by itself, a defence.
Two different problems
It is worth separating two scenarios that are often lumped together, because the protections available are not the same.
The first is the unknown beneficiary. Nobody realises this person exists. They might be a child from an earlier relationship, an adopted sibling, or a cousin in a branch of the family that lost touch generations ago.
The second is the known but missing beneficiary. Everybody knows Uncle Robert is entitled to a quarter share. Nobody has heard from him since 1988.
The statutory protections work well for the first problem and poorly for the second. Recognising which one you are dealing with shapes everything that follows.
Start with reasonable enquiries
Before any of the formal steps, personal representatives are expected to make proper enquiries. That means going through the deceased's papers, address books, correspondence and bank records, talking to family members and old friends, and checking the obvious public records including birth, marriage and death registers and the electoral roll.
Where the family tree is genuinely unclear, particularly on an intestacy, professional probate genealogists can build a verified tree and trace individuals internationally. This is worth doing properly, because the courts and insurers will both want evidence of what was searched, when, and with what result.
A word of caution on so-called heir hunters. Probate research is not regulated in the way that solicitors are, and firms sometimes approach beneficiaries directly offering to reveal an inheritance in exchange for a percentage of it. Those percentages can be substantial. Anyone approached in this way should read the terms carefully and take advice before signing.
Statutory notices and what they actually do
Section 27 of the Trustee Act 1925 allows personal representatives to advertise their intention to distribute. The notice must appear in the Gazette and, where the estate includes land, in a newspaper circulating in the district where that land is situated. It must allow at least two months for claims to come in.
The protection this gives is often overstated, so it is worth being precise. Once the period has expired, the personal representative may distribute having regard only to the claims they actually knew about, and they are not liable to anyone whose claim they had no notice of. That can protect the personal representative against claims from unknown creditors and beneficiaries of whose claims they had no notice when they distributed. It is not, however, a substitute for reasonable enquiries: section 27 expressly preserves any obligation to carry out appropriate searches.
It does nothing for the second. If you know Uncle Robert exists, you have notice of his claim, and no amount of advertising changes that.
Two further limits matter. The section expressly preserves the right of a claimant to follow the property into the hands of whoever received it, so the beneficiaries who were paid out remain exposed even where the personal representative is protected. And the notice gives no protection against a claim under the Inheritance (Provision for Family and Dependants) Act 1975. Those claims must generally be brought within six months of the grant, which is why personal representatives are usually advised not to distribute before that window has closed.
Options for the beneficiary who cannot be found
Where searches have genuinely been exhausted, there are several routes forward, and they are not mutually exclusive.
A declaration of presumed death. Under the Presumption of Death Act 2013, the High Court can declare that a missing person is presumed dead if they are thought to have died or have not been known to be alive for at least seven years. The declaration is conclusive as to the death and its date and is effective for all purposes and against all persons. Where the Act's jurisdictional requirements are met, the High Court can declare a missing person presumed dead if they are thought to have died or have not been known to be alive for at least seven years.
A Benjamin order. Named after the 1902 case of Re Benjamin; Neville v Benjamin [1902] 1 Ch 723, this is a direction from the court permitting distribution on a stated assumption, typically that the missing beneficiary died before the deceased. It protects the personal representative from personal liability. It does not extinguish the missing person's entitlement, so if they reappear, they can still pursue those who received their share. The application requires detailed evidence of the searches carried out, and the cost means it tends to be reserved for larger shares.
Missing beneficiary insurance. A policy that responds if an untraced beneficiary later comes forward. Insurers will normally want to see that thorough searches were done first, and price the cover by reference to the size of the share and the strength of the evidence. It is often used alongside a court order rather than instead of one.
Retaining a reserve. Holding back part of the estate is a practical stopgap, but it is not a long-term answer. A claim to a share or interest in a deceased person's personal estate is generally subject to a twelve-year limitation period from when the right to receive it accrued. Limitation can be more complicated where trust property remains in the hands of a trustee, or where fraud or fraudulent breach of trust is involved.
Indemnities from the other beneficiaries. Widely used, and weaker than they look. An indemnity is only worth what the person giving it can pay, and money distributed to beneficiaries has a habit of being spent. It also does not stop a missing beneficiary suing the personal representative directly.
If it goes wrong: the court's power to excuse
None of the measures above is a guarantee, and personal representatives sometimes find themselves facing a claim despite having acted in good faith. There is a further safety net, although it should be understood for what it is.
Section 61 of the Trustee Act 1925 gives the court a discretion to relieve a trustee from personal liability for a breach of trust where they have acted honestly and reasonably and ought fairly to be excused. The Act treats personal representatives as trustees for this purpose, so executors and administrators can rely on it. Notably, the section covers being excused not only for the breach itself but also for having failed to obtain the directions of the court, which is precisely the position of an executor who distributed the estate without applying for a Benjamin order.
Three points are worth making about it. First, it is discretionary, not automatic. The court must be satisfied on all three limbs, and honesty alone is not enough. Second, the courts have historically been more willing to excuse a lay executor acting without payment than a professional being paid to get it right. Third, and most importantly, it is not something to plan around. It is raised in defence once a claim has already been brought, by which point the personal representative is in litigation regardless of the outcome.
Its practical value is indirect. What persuades a court that someone acted reasonably is contemporaneous evidence: dated records of enquiries made, replies received, searches commissioned and advice taken. An executor who kept that record has a real prospect of relief. One who did not is left asserting that they did their best. That is a strong argument for documenting the process as it happens rather than reconstructing it afterwards.
When there are no heirs at all
If someone dies intestate and no entitled relatives can be found, the estate passes to the Crown as bona vacantia. Before that happens, it is referred to the Government Legal Department and published on the unclaimed estates list, giving relatives an opportunity to come forward. Claims made within twelve years of the administration being completed may attract interest; after that, claims can still be made up to thirty years from the date of death but without interest.
Claims will generally be accepted within twelve years of completion of the administration, with interest paid on the money held. Fully documented claims may still be admitted up to thirty years from the date of death, but without interest once the twelve-year period has expired
That list was temporarily removed from GOV.UK in July 2025 following allegations that it was being used to facilitate probate fraud. It was reinstated in January 2026, after a review found no evidence that the list itself had been the source of fraud, but with less information published about each estate than before. The episode is a useful reminder that identifying and proving entitlement to an unclaimed estate is now a more evidence-heavy exercise than it once was.
One change to watch
The intestacy rules currently distribute an estate among a fixed hierarchy of relatives, and a surviving cohabiting partner inherits nothing automatically no matter how long the couple lived together. In June 2026 the Ministry of Justice consulted on changing this, as part of a wider review titled A Fairer End to Relationships. Among other things, the consultation asked whether qualifying cohabitants should inherit automatically on an intestacy, and whether their right to administer a deceased partner's estate should be aligned with any new entitlement.
These are proposals only. The consultation closed on 14 August 2026, the government has not yet responded, and nothing has changed in the law. But if the proposals were taken forward, personal representatives on an intestacy would face a new kind of question. Identifying relatives is a matter of records and family trees. Establishing whether the deceased was living in a qualifying relationship at the date of death is a question of fact, and one that may be genuinely difficult to answer where the household arrangements were informal, or the relationship was not widely known about.
For anyone in a cohabiting relationship, the practical point is unchanged and worth repeating. Making a will remains the only reliable way to ensure a partner inherits.
Getting the balance right
Most estates involving a missing beneficiary can be resolved sensibly and without going near a courtroom, provided the searching is done properly and documented as it goes. The risk arises when a personal representative, understandably keen to wind things up, distributes on the assumption that someone will probably never turn up.
If you are acting as an executor or administrator and cannot account for everyone entitled to share in the estate, it is worth getting in touch with your solicitor before any money leaves the estate account. The options narrow considerably once it has been distributed.
