1. Do note that disowning has no legal validity and even after disowning a son , he can still inherit the property of his parents of they die intestate.
2. However if a parent wish to give his property to one particular legal heir depriving the other or another child then he can very well do so by way of gift deed or Will.
3. So if your father owns this house then he can very much transfer this to his elder son during his lifetime by way of Gift deed or after his death by way of Will for which he need not disown you.
4. So as long as you are not thrown out of this house you or your wife can continue to use the present address.
