Canon 829

1. From the day of taking canonical possession of office and as

long as they legitimately hold office, everywhere within the

boundaries of their territory, local hierarchs and pastors validly bless the marriage of parties whether they are subjects or

non-subjects, provided that at least one of the parties is enrolled in his Church sui iuris. 2. The hierarch and the personal pastor, by virtue of their office, only validly bless marriages within the boundaries of their jurisdiction when at least

one of the parties is a subject. 3. By the law itself, the

patriarch is endowed with the faculty to personally bless marriages anywhere in the world, as long as at least one of the parties is enrolled in the Church over which he presides, observing

the other requirements of law.
