Birth certificates and parental responsibility for unmarried fathers — step by step

REVIEWED BY: Sean McNamara on 2026-09-01

Why the birth certificate matters

For births registered in England and Wales on or after 1 December 2003, an unmarried father who is named on the birth certificate automatically acquires parental responsibility under the Children Act 1989. If you are not on the certificate, you do not have parental responsibility — even if you are the biological father, pay maintenance and see your child. Being named is the simplest and cheapest route to it.

For births registered before 1 December 2003, being on the certificate does not confer parental responsibility on an unmarried father — a different route (agreement or court order) is needed.

Step 1 — Registering the birth together

Births must be registered within 42 days at a register office (in the district where the baby was born, or by appointment elsewhere with the details forwarded).
If the parents are married, either parent can register alone. If unmarried, both parents' details can only be included in specific ways — usually both parents attend together, or one attends with a signed statutory declaration from the other, or a statutory declaration plus other prescribed information.
The mother can decline to name the father. The registrar cannot force inclusion, but if the father attends and confirms paternity, his details can be recorded.

Step 2 — If the father is not on the certificate

Options, in rough order of simplicity:

1. Re-registration. If both parents agree, the birth can be re-registered to add the father. Both complete the registrar's forms (a statutory declaration of parentage is commonly involved) and attend the register office. Re-registration does not erase the original entry — a new entry is created. 2. Parental responsibility agreement (form C(PRA2)). If the mother will not agree to re-registration but does agree you should have parental responsibility, you can file a parental responsibility agreement with the family court; it must be signed and witnessed and, once sealed, gives you parental responsibility without a hearing. 3. Parental responsibility order. If the mother does not agree, apply to the family court for a parental responsibility order. The court applies the welfare principle (the child's welfare is paramount) alongside the welfare checklist. Most applications by committed, involved fathers succeed, but the court examines commitment, attachment and motivation. 4. A child arrangements order "lives with" you also gives an unmarried father parental responsibility for as long as the order is in force.

Step 3 — Proving paternity

DNA testing: use an accredited tester if the result may matter in court; a Ministry of Justice-approved list of accredited testers is published on gov.uk.
A declaration of parentage under the Family Law Act 1986 can be sought from the court if parentage is disputed; once declared, the birth can be re-registered.

Step 4 — After you have parental responsibility

You can obtain a copy of the birth certificate from the General Register Office.
Parental responsibility means involvement in major decisions (school, medical treatment, passports, religion) and the right to be consulted — it does not automatically mean equal time; contact arrangements are separate.
Keep the certificate safe; you will need it for passports, benefits and school applications.

Common pitfalls

Assuming being named on an older (pre-2003) certificate gives parental responsibility — it does not.
Paying maintenance or being on the child's records does not itself confer parental responsibility.
Taking a child abroad or changing a name without parental responsibility can be a serious issue — resolve status first.
