Canon 830

1. As long as they legitimately hold office, the local hierarch

and the pastor can give the faculty to bless a determined marriage within their own territorial boundaries to priests of any

Church sui iuris, even the Latin Church. 2. However, only the

local hierarch can give a general faculty for blessing marriages

with due regard for can. 302, 2. 3. In order that the conferral of the faculty for blessing a marriage be valid, it must be

expressly given to specified priests; further, if the faculty is

general, it must be given in writing.
