GRONI rules for a child under 18
A parent or child under 18 applies using the child form. The qualified applicant or applicants depend on the family circumstances. nidirect lists both parents where both qualify, the mother where the other parent does not have parental responsibility, and other qualified applicants in specified cases such as death or guardianship. The signatures must be witnessed by a justice of the peace, lay magistrate or practising solicitor. nidirect: recording a change of name
GRONI says a person under 18 can record their name or surname once. This is a limit of that registration route. A child’s name change also raises parental responsibility and welfare questions; do not infer that the register’s form rules settle every other organisation’s consent requirements.
