A father in his right as patria potetas or otherwise can effect a partition between himself and his son of the joint family property of HUF. However, he has to allot equal shares to the sons.
The father is expected to act bona fide and only aggrieved party can seek relief by way of appropriate proceedings. However, till such a partition is held invalid by a competent court, it must be held as valid.
As far as the ITRs are concerned you can obtain the details from IT department by submitting an application under RTI act also as a member of the HUF
