1.Assuming the house documents are in your name, you are at liberty to WILL it to anybody, including your wife and /or children, since the property is your Absolute Property when it has landed in your hand. Therefore you can execute a 'WILL' in respect of the house property in favour of your wife only.
2.Your wife can be the beneficiary of the property inherited by you from your father, after your lifetime, if it is bequeathed to her by you by executing a 'WILL' in her favour, even though you have two adult daughters, since you are the absolute owner.
3.However it is to be noted that the property is assumed to be self acquired property of your father only and not an ancestral property of your forefathers.
