Monaco - Passport & Nationality - Monaco Citizenship through Marriage

A foreign woman, having reached her majority or not, who marries a Mongasque acquires Mongasque nationality.

However, she does not become an elector or eligible to be candidate in elections until a period of five years has passed since the date of the marriage.

A Mongasque woman who marries a foreigner retains her Mongasque nationality unless she expressly states that she wishes, in conformity with the arrangement of the national law of her husband, to acquire the nationality of this latter.

This declaration must be made at the time of the celebration of the marriage in answer to the questions posed by the Registrar, otherwise it is invalid; such declaration is to be noted on the marriage certificate.

If the marriage is celebrated abroad, the declaration must be made before the marriage is celebrated, before a diplomatic or consular representative of the Principality of Monaco otherwise it is invalid.
