Best Way to Claim Guardian's Allowance When the Surviving Parent Is Missing
If you are raising a child and one parent has died but the other parent is alive and absent, your best approach is to identify which of the four current surviving-parent circumstances applies to your situation, gather the specific evidence HMRC needs for that circumstance, and submit form BG1 with it clearly documented. The claim is more involved than a both-parents-deceased application, but the benefit — £22.95 per week per child, tax-free, on top of Child Benefit — is exactly the same.
Most carers in this situation assume Guardian's Allowance requires both parents to be dead. That is the standard qualifying condition, but current HMRC guidance also recognises four circumstances where one parent has died and the other is alive. The difficulty is that GOV.UK describes them briefly, and the BG1 form does not walk you through which circumstance you are relying on or what evidence to attach.
The Four Current Surviving-Parent Circumstances
Guardian's Allowance can be paid when one parent has died and the surviving parent meets one of these conditions:
| Exception | What It Means | Evidence HMRC Typically Expects |
|---|---|---|
| Untraceable | At the date the other parent died, you did not know where the surviving parent's whereabouts were and tried but failed to trace them | Written statement of your efforts to find them and any last-known contact details |
| Imprisoned | At the date the other parent died, at least two years of the surviving parent's custodial sentence remained; being on remand does not qualify | Prison name, sentence details, and evidence of the remaining term at the date of death |
| Hospital-detained | The surviving parent is detained in hospital by a court order under the relevant legislation | Details or a copy of the court order and the legislation it relies on |
| Paternity not established | The mother died and the father's paternity has not been established | The child's full birth certificate and any further information HMRC requests |
The divorce or civil-partnership-dissolution route was removed for new claims from 7 April 2025 by the Child Benefit and Guardian's Allowance (Miscellaneous Amendments) Regulations 2025. Transitional protection may apply to claims or awards already made before that date.
Each circumstance has its own evidence trail. The "untraceable" route applies only if, at the date the other parent died, you did not know where the surviving parent was. HMRC also expects you to demonstrate reasonable efforts to locate them. What counts as reasonable depends on the circumstances, but typically includes attempts to contact the parent through last-known addresses, family members, or social services.
Who This Is For
- A grandparent raising a grandchild after one parent's death, when the other parent has disappeared and cannot be found
- A relative caring for a child whose father was never named on the birth certificate
- A carer whose situation involves a surviving parent in prison with a long sentence
- Anyone who read the GOV.UK page, saw "one or both parents have died," and assumed they did not qualify
Who This Is NOT For
- Carers where both parents have died — the standard claim process is simpler and does not require exception evidence
- Anyone seeking legal advice on custody or parental rights — Guardian's Allowance is a financial benefit claim, not a custody application
- Carers in a dispute with a living parent over the child's care — Guardian's Allowance does not decide who should raise the child

Everything in this article as a printable checklist — plus action plans and reference guides you can start using today.
Approach 1: DIY With GOV.UK and the HMRC Helpline
You can do this entirely free. Download BG1 from GOV.UK, call the Child Benefit Helpline (0300 200 3100) to ask which circumstance applies, and submit the form with the relevant evidence.
Strengths: No cost. The helpline staff know the rules and will answer direct questions about your specific situation.
Limitations: The helpline answers questions but does not help you organise your evidence package. The interactive BG1 PDF cannot be saved mid-completion, so you need everything ready before you start. Guardian's Allowance can be backdated up to three months, so submit promptly; the official guidance does not say that a separate written request is required.
Approach 2: Charity Advice (Kinship, Citizens Advice, Family Rights Group)
Free charity support can be excellent, particularly if you reach a specialist welfare rights adviser. Kinship (0300 123 7015) specialises in kinship carer issues. Citizens Advice bureaux handle all benefits.
Strengths: Human support, often with experience of your specific situation. Kinship advisers understand kinship care in a way generalist services may not.
Limitations: Specialist appointments fill quickly. A Citizens Advice generalist may not have handled a surviving-parent exception case before. You may wait weeks for an appointment while your backdating window shrinks.
Approach 3: Welfare Rights Consultant
A private welfare rights consultant can manage the entire claim for you. Typical fees range from £50 to £150 per hour, and some take a percentage of any backdated award.
Strengths: Professional handling from start to finish. Useful if your situation is unusually complex or involves multiple benefits.
Limitations: Expensive relative to the benefit amount (£22.95/week). A percentage-based fee on a backdated award can take a significant portion of the money you are owed.
Approach 4: Guardian's Allowance Claim Guide
The Guardian's Allowance Claim Guide is a self-service preparation resource that covers the four current surviving-parent circumstances with the specific evidence requirements for each, a pre-filling worksheet for BG1 so you assemble everything offline, and backdating date guidance.
Strengths: Covers the exact scenario where free resources are thinnest — exception claims. Includes the certificate postal tracking sheets. Costs less than a single hour of a welfare rights consultant.
Limitations: Self-service — you still prepare and submit the claim yourself. It is not a substitute for specialist legal advice if your situation involves a contested custody dispute.
The Critical Step Most People Miss
Whichever approach you choose, submit BG1 promptly. Guardian's Allowance can be backdated for up to three months before HMRC receives the completed claim, provided you met the conditions throughout that period. The official guidance does not say a separate written request is required. Thirteen weeks at £22.95 is £298.35 for one child and £596.70 for two.
The official guidance does not require a separate backdating form or state that a written request is needed. If you include a note, explain when you became eligible and ask HMRC to consider the earliest allowable date.
Frequently Asked Questions
What counts as "reasonable efforts" to trace a missing parent?
At the date the other parent died, you must not have known where the surviving parent was. HMRC requires reasonable efforts to trace them; examples include attempts to contact the parent at their last-known address and enquiries with relatives or friends. A written statement can explain what you tried.
Can I claim Guardian's Allowance if the father was never on the birth certificate?
Yes. Current HMRC guidance says Guardian's Allowance may be paid where the mother has died and the father's paternity has not been established. The full birth certificate is required, and HMRC may ask for further information. The parents' marital status is not a separate condition under the current regulations.
What if the surviving parent is in prison but for less than two years?
The prison route requires at least two years of the custodial sentence to remain at the date the other parent died; a parent on remand does not qualify under this route. Another circumstance may apply separately, such as not knowing the surviving parent's whereabouts at the date of death or paternity not being established.
How long does an exception claim take compared to a standard claim?
GOV.UK does not publish a processing-time target for Guardian's Allowance claims. HMRC says it will acknowledge receipt and return any certificates sent with the claim, then write with its decision. A claim relying on a surviving-parent circumstance may require HMRC to assess additional evidence, but the guidance does not give a separate timeline.
Does the surviving-parent exception affect how much I receive?
No. The weekly rate is the same regardless of which qualifying route applies — £22.95 per child in 2026/27. The exception affects only whether you qualify, not the amount.
