Change of name
a) British law permits name changes after marriage. However, the change of name is not displayed on British marriage certificates.
b) The Consulate, on the other hand, must attest the name change. One of the following documents displaying the change of name must be submitted (original and photocopy):
a) British passport; or
b) British visa with photo or biometric residence permit card; or
c) British driving licence; or
d) CitizenCard (former Validate UK - proof of age); or
e) British birth certificate of the couple's child.
c) Deed polls (British notarial document) are not accepted as proof of name change for the Brazilian spouse, although it is accepted for the foreign / British spouse.
d) The absence of proof of name change prevents the surname from being registered in the Brazilian marriage certificate or in any other consular service that might eventually be requested.
e) Forename changes, even if attested by a British official document, are only possible if by means of court decision in Brazil.
