Does the Father Have to Agree to a Child’s Name Change?
Quick answer
Who should skip this
Skip a child deed poll if the father holds parental responsibility and will not sign. Skip InstantDeedPoll for the court application itself — that is form C100 on GOV.UK. Skip us if the young person is already 16.

When is the father’s consent legally required?
Whenever he holds parental responsibility: married to the mother at the birth; named on the birth certificate for registrations from December 2003 in England and Wales; or holding a court order or parental responsibility agreement. Contact, maintenance and how the relationship ended do not remove it. Separation is irrelevant to this test.
Same rule after divorce or separation. Broader map: parental responsibility and name changes.
When is his consent NOT required?
When he does not hold parental responsibility — classically an unmarried father not named on the birth certificate and without a court order or agreement. Then the mother and any other holders can proceed. If you are unsure, check GOV.UK before you pay anyone, because a deed poll made without a required consent is not valid.
Official test: GOV.UK parental rights. The which-document checker has a refused-consent skip-us path.
What if he refuses?
Then the name cannot lawfully be changed by deed poll. Apply for a Specific Issue Order on form C100; a judge decides on the child’s welfare, not the parents’ dispute. Our checkout blocks the purchase when consent cannot be confirmed, so nobody buys a document that would not be valid.
Free guidance: GOV.UK — change a child’s name. Do not buy a posted “family deed poll” to paper over a missing signature — the paper does not create consent.
How do we document his consent if he agrees?
He signs and dates a consent letter stating he agrees to the change from the child’s current name to the new name. The child deed poll pack generates one for every holder of parental responsibility. Keep the signed letters with the deed; HM Passport Office and schools may ask for them.
