Malta - Passport & Nationality - Maltese Citizenship through Marriage
Widows and widowers of a Maltese citizen (where the spouse died within the first 5 years of marriage) may apply for Maltese citizenship by marriage 5 years after the date of the marriage to their deceased spouse.
Persons separated from a Maltese spouse may still apply for Maltese citizenship by marriage provided they lived together for 5 years
Prior to 10 February 2000 the 5 year period of marriage did not apply, while before 1 August 1989 only the foreign wife of a Maltese man was eligible for citizenship by marriage.
