One of our land sold twice

The proper way is to get the entire land resurveyed by applying to Tehasildar and paying fees and then correcting the mistake, if it happened without intention to cheat.

Your father and his brother, if alive, should be in the know of the things. If they are not alive, no criminal case lies.

Thanks Sir for immediate reply, My father and one of his brother is alive, eldest brother is died actually who only initiated the sale for her daughters marriage and that land is his share, since they didnt do any settlements documents all there were signed the sale deed.

Finally we agreed to compensate him, is there a way to cancel the 1989 sale deed, and do we document like we are compenstating for the that land?

You can approach to Legal Services Authority and enter into a compromise settlement, which can not be challenged any where else.  Contact an advocate and get the compromise award registered after such settlement made before LSA.
