ANSWER:

If the marriage contract was not done yet, she shouldn’t be in contact with him. If he is already married to her, there is no problem in him giving to her or to her father.

Once the Mahr is bought by the groom for the bride, is there any ruling that the Mahr needs to be given directly all by the groom himself to the bride or can he ask his parents or the girl’s parents to hand it over to her.
