Certification required: The doctor’s letter must bear the original signature of a UK-registered doctor, including their General Medical Council (GMC) number. If the doctor's signature is not registered with the Foreign, Commonwealth & Development Office (FCDO), the document must be certified by a UK solicitor or notary public before it can be apostilled.
Original document: The apostille is applied to the original doctor’s letter or to a solicitor/notary-certified copy, depending on the requirements of the receiving authority.
Eligible for e-apostille: Yes, if the document is certified with a qualified electronic signature by a UK solicitor or notary.
