Heir Hunters UK (2026): How Missing Heirs Are Traced and What They Charge

An heir hunter is a genealogical research company that specialises in tracing living relatives of people who have died intestate (without a will) when those relatives cannot be easily identified or located. Heir hunters are typically instructed in two scenarios: (1) by the Treasury Solicitor's Bona Vacantia Division (BVD), which publishes notices of intestate estates with no known heirs before the estate passes to the Crown; and (2) by estate solicitors, administrators, or executors handling an estate where potential beneficiaries are known to exist but cannot be located. The BBC documentary series 'Heir Hunters' brought the process to public attention — the premise is that the firm races to locate a distant relative and sign them to a fee agreement before the estate passes to the Crown as bona vacantia. There is genuine commercial urgency: if no heir claims the estate within a reasonable period, it passes to the Crown and can only be reclaimed within 12 years (after which the Crown's title is extinguished by limitation).

Heir hunters use a combination of public records and private databases to reconstruct the deceased's family tree and identify living descendants or collateral relatives. Primary records used include: General Register Office (GRO) birth, marriage, and death records; census records (now open to 1921 online); probate records and wills; electoral rolls; HM Land Registry; Companies House; social media and online sources. For overseas relatives: foreign civil registration records, church records, immigration and naturalisation records, and international genealogy databases such as FamilySearch and Ancestry. The difficulty increases with the distance of the relationship: locating a first cousin requires mapping two generations of the deceased's family; locating a fourth cousin may require research across six or more generations. Professional genealogists are members of bodies such as the Association of Professional Genealogists (APG), the Society of Genealogists, or Genealogy Pro. The quality of research and the evidence produced in the family tree must meet the standard required by the estate solicitor and ultimately by HMRC and the Probate Registry.

Heir hunting firms typically charge a contingency fee of between 10% and 25% of the heir's share of the estate, charged only if a successful claim is established and the heir receives their inheritance. Most work on a no-win, no-fee basis — if no heir can be identified, no fee is charged. The exact percentage depends on: the complexity of the research (a straightforward first-cousin trace costs less than a fourth-cousin search); the size of the estate (a lower percentage is sometimes negotiated for very large inheritances); and the firm's pricing policy. An heir who is found for a £100,000 estate and signs a 20% fee agreement will receive £80,000 net. The fee agreement is usually presented to the heir before any details of the estate are revealed — the heir must decide whether to sign without knowing exactly how much is at stake. The heir hunter's fee is paid from the heir's share, not from the estate generally; other beneficiaries are unaffected.

No — you are not legally required to sign an heir hunter's fee agreement. You have the right to decline and instruct your own independent solicitor or genealogist to verify the family tree and make a direct claim to the estate. The advantage of doing so is that you keep 100% of your share rather than paying 10–25% to the heir hunting firm. The disadvantage is that you bear the cost and risk of the independent research yourself. Before you decline, consider: (1) whether you can independently verify the connection and navigate the claim process; (2) the cost of instructing an independent professional may exceed the heir hunter's fee for smaller estates; (3) the heir hunter may have already established the research and signing with them is genuinely efficient. Reputable heir hunting firms are members of HEIR Societies or the APG and will provide the fee agreement in writing for you to consider. The fee agreement is a contract — read it carefully, check the percentage, and if in doubt obtain legal advice before signing.

If no qualifying relative can be identified and the estate has been properly advertised (using statutory notices under section 27 of the Trustee Act 1925 and the Bona Vacantia Division's processes), the estate passes to the Crown as bona vacantia. 'Bona vacantia' means 'ownerless goods' in Latin. For English and Welsh estates, the Crown's rights are exercised by the Treasury Solicitor (Government Legal Department), which publishes the estate details on the Bona Vacantia website. A relative who subsequently comes forward and proves their entitlement can reclaim the estate from the Crown — but only within 12 years of the estate passing (limitation period). After 12 years, the Crown's title is absolute and no claim can be made. The BVD sometimes makes discretionary grants from estates to people who were closely connected to the deceased but have no legal entitlement — such as cohabitants or close friends — particularly in hardship cases. The BVD website publishes a list of unclaimed estates; anyone who believes they may have a claim should search it and act promptly.

Yes — personal representatives and estate solicitors routinely instruct heir hunting firms when they know potential beneficiaries exist but cannot locate them. This most commonly arises where: the deceased had children from a prior relationship who have lost contact; a will names beneficiaries who have moved with no forwarding address; the intestacy rules indicate entitlement for a class of relative (e.g. first cousins) who are not immediately identified; or a beneficiary is known to have emigrated with no contact details. The heir hunter acts as a research agent for the estate in these cases, and their fee comes from the beneficiary's share (not from the estate generally). An executor who cannot locate a beneficiary after reasonable efforts can apply for a Benjamin order — a court order permitting distribution on an assumption about the missing beneficiary, protecting the executor from personal liability if the assumption is later wrong. A Benjamin order is an alternative to indefinitely delaying administration; instruction of an heir hunter is the first step before reaching that stage.

A bona vacantia case is one where no heir exists — the deceased died intestate with no living relatives within the statutory order of priority, or all known relatives have predeceased. The entire estate passes to the Crown. A missing beneficiary case is one where a beneficiary exists in principle (e.g. a named legatee under a will, or a class of relatives entitled under intestacy) but that individual cannot currently be located — their address is unknown, they may have emigrated, or their contact details have been lost over many years. In a missing beneficiary case the estate is not escheated; the executor simply cannot distribute that person's share until they are found or a Benjamin order is obtained. Heir hunters are useful in both scenarios but for different reasons: in a bona vacantia case, they race to identify any relative before the Crown's right crystallises; in a missing beneficiary case, they trace a person whose existence is already known. In both, the research process is similar but the urgency and fee basis may differ.
