When is the father’s consent legally required?
Whenever he holds parental responsibility: married to the mother at the time of 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. Consent is required regardless of contact, maintenance payments, or how the relationship ended — those do not remove parental responsibility.
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. In that case the mother (and any other holders) can proceed alone. If you are unsure, check the gov.uk guidance before ordering, because a deed poll made without a required consent is not valid.
What if he refuses?
Then the name cannot lawfully be changed by deed poll. The route is a Specific Issue Order using form C100 — the court fee applies, and a judge decides on the child’s welfare. Free guidance is at gov.uk/change-a-childs-name. Our form blocks checkout when consent cannot be confirmed, precisely so nobody buys a document that would not be valid.

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 poll; HMPO and schools may ask for them.
