When Can You Use a DNA Test to Change a Birth Certificate?

You can apply to re-register or amend a child’s birth certificate when:

• The father’s details were left off the original birth certificate
• The person previously named as the father is not the biological parent
• You are adding the biological father following proof of paternity
• There has been a court ruling confirming paternity based on DNA evidence

In all of these scenarios, a court-approved legal DNA paternity test can be submitted as evidence to support your application.

What Type of DNA Test Is Accepted?

The test must be a legal DNA test (also known as a court-approved or chain of custody test). This means:

• The test is carried out by a UKAS-accredited testing company
• Samples are collected under strict procedures (e.g. witnessed by an independent third party)
• A full chain of custody is maintained
• The laboratory provides a signed, admissible report suitable for legal or court use

Peace of mind/home testing kits will not be accepted for legal purposes.

How to Change the Birth Certificate Using a DNA Test

The process differs depending on your situation. Here are the two most common routes:

1. Adding the Father’s Name

If the father's name is not currently on the birth certificate, you can apply to re-register the birth using form GRO 185 (from GOV.UK). You’ll need:

• The original birth certificate
• A copy of the legal DNA paternity test results
• The signed declaration by both parents (or a court order, if applicable)

Once processed, the General Register Office (GRO) will issue an updated birth certificate with the father’s name included.

2. Removing or Replacing a Father's Name

If the current birth certificate names someone who is not the biological father, and you now have DNA evidence proving who is, you’ll need to apply to the Family Court.

A judge may:

• Issue a declaration of parentage
• Authorise the removal or amendment of the father's name on the birth certificate

This is more complex and usually requires:

• Legal representation
• Court fees
• A legal DNA test report to be submitted as part of the evidence

The outcome will be passed to the GRO, who will then amend the birth record.

Frequently Asked Questions

Can I use a home DNA test to change a birth certificate?
No — only legal (court-approved) DNA tests are accepted by courts or the General Register Office.

What if the mother doesn’t agree to the DNA test?
You may need to apply to court for a declaration of parentage. The court can order a DNA test if appropriate.

Do I need a solicitor to change the birth certificate?
Not always — but in complex cases (like removing a father's name), legal advice is strongly recommended.
