Yeah, if Gold had documents on Cinderella’s baby, they would probably be just like the ‘extensive’ records he keeps in his shop – like the one on Michael Tillman….it was a blank piece of paper.
Legal adoptions require an extensive background check and probably at least one visit to the prospective adoptor’s home.
That wasn’t possible in Regina’s case.
I seriously doubt Regina wanted that kind of attention.
Look how she reacted to Kurt and Owen being in SB.
As far as the curse being broken and Regina being able to call authorities on the Charmings, NO she can’t.
There is no record of Storybrooke, Regina, Snow, David, etc.
Regina would have a lot of explaining to do if she did call the real world authorities.
