Circular of 2 June 1981 of the Directorate General for registers and notaries - basic guidelines: (a) The Book shall be issued to a parent or to parents who acknowledge a child born out of wedlock or who adopt a child, and to persons contracting marriage, unless of course they already have a Family Book for the first reason; (b) The Book shall contain records only for children of both parents, or children who have only one legally recognised parent.
