Question on inheritance?

If the property was ancestral, the father no right to write a will at all and it belongs to both the sister and brother. The will becomes null and void. If the property is the father's self acquired , as he has every right to execute a will the daughter has no right at all.

No the son was given all legal and personal rights to the land and does not have to make any consent on the dealings of it with anyone else. It is completely and utterly the sons property and the son may do with it as he pleases without having to consult any family or get acceptance from them. The sister has no rights to the land at all. If the son kept it he could even have her legally kept off the land because he controls it!

Nope. If the daughter had issues with the will, she should have contested it ASAP. Unless she does this within a certain period of time, she has no chance of claiming a right to any of the inheritance. And in order for HER to contest the will, she would have to be able to prove that, at the time the will was written, the father was either not mentally competent or had been coerced in some way to favor the son.

It depends upon whether the property acquired was earned by his deceased father or was it inherited to him too.If it was earned by his father,he needed not taking the consent of his sister but if it was an ancestral one then the daughter is entitled equal right.

How nice of the son to assume the full tax liability before he gives his sister her fair share.

No.
