Re: Nikkah naama...
Each country has its own laws & rights, in the west, if you don't sign a marriage contract, she is entitled to his properity, the one he buys after the marriage or vice versa. So by simply writing it on a piece of paper, the nikkah contract its would not be binding in my eyes, you need more than that.
if she has signed a paper saying that she'll only recieve mehr in case of divorce than i think she will not receive any more from his assets; atleast legally this makes sense. in a way she will have signed off her entitlement under state law, no?
