May I know the place `mothers place or in laws place for the seemantham to be performed

Normally, the Seemantham is performed at the Boy (husbands) home side. However, if for some reasons of practicability and available resources, it can be performed at any places but the general idea is, the total cost is borne by the boys side. Even after delivery, which takes place at the girls/wifes parents place, the expenses for the namakaranam too is to be borne by the boys/husband side!
