Vasanth ji, It is true that as told by Anish ji the ancestral property can be sold for legal necessities and then if other legal heirs contest, he can take the defence that it was sold for the marriage purpose. But if you want to know about the property distribution, well it has to be distributed equally among all the legal heirs. I mean to say, whatever proerty father gets from his anscestral property, has to be equally divided among his legal heirs. It cant be divided taking into consideration how many kids each wife has. Each child should get equal share.
