Canon 509

1. An order or congregation cannot validly erect a house without the written consent of the eparchial bishop. If it is the

case of erecting the first house of an order or congregation of

patriarchal right in some eparchy, the consent of the patriarch

is required within the territorial boundaries of the patriarchal

Church, or in other cases, the consent of the Apostolic See. 2.

The matters mentioned in can. 437 shall apply also to houses of

orders and congregations.
