DNA Testing for Birth Certificate Changes: How to Add, Remove or Correct a Father

Can a DNA test change the father on a birth certificate?

Yes. In England and Wales, a legal DNA test from an approved tester is accepted as proof that the wrong man is named as the father on a birth certificate. London Diagnostics Clinic arranges legal DNA testing for birth certificate corrections, including when the mother, the named father or the biological father lives outside the UK.

• Removing the wrong father: this is a correction. You apply to the General Register Office (GRO) with evidence such as a DNA test record from an approved tester or a court order.
• Adding a father who isn't named: this is a re-registration. It usually needs the parents' agreement, not a DNA test.
• The test must be legal, not peace of mind. The laboratory must meet ISO 17025 standards, and the samples must be collected securely, with identity checks.
• The original details stay on record. A full certificate shows a note in the margin explaining the correction.

Which birth certificate change do you need?

The right route depends on what is wrong with the certificate. Getting this right first saves time and money.

A correction fixes information that was wrong at the time of registration. You cannot use it to record later changes, such as a new surname after marriage.

How do you remove the wrong father from a birth certificate?

You must prove that the man named on the certificate is not the child's biological father. The GRO accepts several kinds of proof:

• a DNA test record from an approved tester
• a court order
• evidence confirming who the true biological father is
• other evidence showing the named man could not be the father

Who can apply? The named father does not always have to take part. The GRO can correct the entry if two of these three people apply: the mother, the biological father, or the man named on the certificate. At least one of them must sign the form, and you must give contact addresses for all three.

What makes a DNA test acceptable? To count as proof in England and Wales, the laboratory must meet ISO 17025 accreditation standards, and there must be evidence that the samples were collected securely. A home peace of mind kit will not be accepted.

The steps

1. Book a legal DNA test. Each person's identity is checked and their sample is taken by an independent collector under chain of custody.
2. Receive your legal report. It confirms whether the named man is excluded as the father, and, if he took part, whether the biological father is confirmed.
3. Apply to the GRO. Send the correction form with the DNA report and the fee, which is £83 or £99 depending on the case.
4. Make statutory declarations if asked. For serious corrections, the GRO may ask for sworn statements. The DNA tester may also be asked to make one, and may charge for it.
5. Order the corrected certificate. A full certificate shows the original entry with a note in the margin. A short certificate shows only the corrected details.

How do you add a father to a birth certificate?

If no father was named when the birth was registered, adding him is a re-registration, not a correction. It is done with form GRO 185 and usually needs both parents to agree.

When both parents agree, a DNA test is not normally required. Many parents still choose one first for certainty, especially when the relationship was short or the father is living abroad.

When the mother does not agree, the father cannot simply be added. He usually needs a declaration of parentage from the family court, and a legal DNA test is the strongest evidence for that application.

If the wrong father is already named, that entry must first be corrected using the process above before the biological father can be recorded.

Evidence from outside the UK: the GRO's guidance says court orders and evidence such as DNA tests obtained outside the UK are not acceptable for re-registering a birth. If any part of your case involves another country, it is important to use a UK-accredited legal testing route. Speak to us first.

What if one parent lives abroad?

This is common. The mother may be in London while the named father is in Lagos, or the biological father is working in Dubai. The test can still be done, but the collection abroad must meet the same legal standard as a collection in the UK.

We make that possible by:

• arranging identity checks and sample collection by an approved professional in the other person's country
• keeping one unbroken chain of custody, so every sample can be traced from collection to the laboratory
• accompanying samples where needed, so they reach the accredited laboratory securely
• coordinating everyone through one case manager, across time zones

Frequently asked questions

Can I use a home DNA test to change a birth certificate? No. Home peace of mind tests have no identity checks or chain of custody. The register office needs a legal test from an approved, ISO 17025-accredited tester.

Does the man named on the certificate have to take part? Not always. The GRO can correct the entry if two of the mother, the biological father and the named man apply, with at least one signing the form.

Can I add the father's name without the mother's agreement? Usually not directly. The father normally needs a declaration of parentage from the family court, and a legal DNA test is strong evidence for that application.

Will the old father's name disappear completely? No. The original entry stays in the register. A full certificate shows a note in the margin with the corrected details, while a short certificate shows only the corrected information.

How much does it cost to correct a birth certificate? The GRO correction fee is £83 or £99, plus the cost of new certificates. The legal DNA test is a separate fee.

What if the father lives in another country? We arrange identity checks and sample collection near him, with a full chain of custody, so the result meets the UK legal standard.

Is this guide relevant to Scotland or Northern Ireland? This guide covers England and Wales. Scotland and Northern Ireland have their own processes, and we can advise on those.
