How to Trace a Missing Parent for Guardian's Allowance: Reasonable Efforts Explained

One of the five surviving parent exceptions for Guardian's Allowance covers the situation where one parent has died and the other parent is missing. In Great Britain, Section 77(2)(a) of the Social Security Contributions and Benefits Act 1992 says you can qualify if, at the date the other parent died, you did not know the surviving parent's whereabouts and have made "all reasonable inquiries" to find them. Northern Ireland has a parallel provision in Section 77 of the Social Security Contributions and Benefits (Northern Ireland) Act 1992.

The problem is that neither the statute nor the BG1 Notes define what "reasonable" means. HMRC decision-makers assess it case by case, and the guidance for their staff (the internal CBTM manuals) is not written in plain language. Carers are left guessing at what they need to do — and many either give up or submit weak evidence that gets the claim rejected.

What HMRC Is Actually Looking For

HMRC does not conduct its own investigation to find the missing parent. The burden is entirely on you to show that you tried and could not locate them. A decision-maker will read your written statement and supporting evidence, then assess whether your efforts were proportionate to the circumstances.

"Reasonable" is not the same as "exhaustive." You are not expected to hire a private investigator or travel the country. But you need more than "I haven't seen them in years." HMRC wants to see documented, proactive steps with outcomes.

Steps That Count as Reasonable Inquiries

Based on the statutory framework and HMRC's published decision-making guidance, these are the types of efforts that strengthen a claim:

Contact known family members. Write to or phone the missing parent's relatives — parents, siblings, former partners. Keep a dated record of each attempt and the response (or lack of response).

Report to the police. File a missing persons report with the local police force. The report number and a copy of any correspondence serve as strong evidence. Even if the police cannot find the parent, the fact that you reported them missing carries weight.

Ask social services. Contact your local authority's children's services or social work team. If they were previously involved with the family, they may have a last known address. Ask them in writing and keep the response.

Include any relevant DWP enquiries. HMRC may consider records of enquiries you made to the Department for Work and Pensions as part of your tracing evidence. Keep copies of any request and response.

Contact the Salvation Army Family Tracing Service. The Salvation Army operates a free family tracing service in the UK. They accept referrals from individuals trying to locate a family member. Getting a reference number from them is concrete evidence of a search.

Check publicly available records. Electoral roll searches, social media, online directories — these are quick and free. Note the dates you searched and what you found (or did not find).

How to Document Everything

Documentation is what separates a successful claim from a rejected one. For each step:

• Date every action. Write down when you contacted each agency, when you made each phone call, when you searched each database.
• Keep copies of all correspondence. Letters, emails, text messages — anything showing you reached out and what the response was.
• Record non-responses. If you wrote to three of the parent's family members and none replied, that is evidence. Write: "Letter sent to [name] on [date]. No response received as of [date]."
• Write a clear chronological statement. HMRC decision-makers read a narrative. Start from when the parent disappeared, explain what you knew, list every step you took in order, and state the outcome.

Include your written statement and supporting records with Form BG1. BG1(CS) is for details of additional children, not for extending a tracing statement. If you need more space, follow the current BG1 instructions for providing extra information.

What If You Genuinely Cannot Trace Them?

If the parent left years ago, has no known family or was from overseas, your search options may be limited. If the parents were unmarried when the child was born, the father was never registered on the birth certificate and the mother has died while paternity remains unestablished, a separate statutory exception may apply; that is not the missing-parent tracing test. HMRC assesses what tracing steps were reasonable in the circumstances.

A carer who says "I last knew where the father lived in 2020, and I have contacted his relatives, the police and social services without locating him" may be showing reasonable efforts if those inquiries and their outcomes are documented. A bare assumption that the parent is abroad, without any tracing inquiries, is unlikely to show reasonable efforts.

The key is showing that you did what was available to you and documented it. An HMRC officer makes the initial decision from the claim and evidence you provide. If HMRC refuses the claim, you can request a mandatory reconsideration and then appeal to a tribunal.

If Your Claim Is Rejected

If HMRC decides your efforts were not sufficient, you will receive a decision letter explaining why. You can request a mandatory reconsideration within 1 month of the date on the decision letter, supplying additional evidence of your search. If the reconsideration is also refused, you can appeal to the First-tier Tribunal (Social Security and Child Support) — or the Northern Ireland Appeals Service.

Appeals on the "reasonable efforts" question are fact-specific. If you can show additional steps you took that were not in the original submission, or if HMRC's decision-maker set an unreasonably high bar, a tribunal may overturn the decision.
