Father might sell his property due to issues with wife. What can i do?

In case, the property is a self made property of your father, he is free to dispose it of as per his own discretion. In Case of the property being ancestral, u have a right in the property and have a share therein.

The property being self acquired may be dealt with by your father in any manner he deems fit. Unfortunately therefore, what that means is that he has the right to remove you from the property as well as sell it to anyone he pleases. The best way forward is to maintain cordial relations with him so that he does not deny you a share in the property

You yourself have states that your father have purchased it with his own income ,hence he can sell the same without asking you ,you can only convince him not to sell or buy yourself the property .

In case of self acquired property your father has right to give the property to whoever he desires, so legally you cannot ask your father share in his property.
