My wife doesn't get along with my mother. We have our father's house in punjab and I and my wife are living in mumbai. My mother is living alone in punjab and I support her financially.
My father the following will before he died in an accident in 2002.
He has given me the ownership of the house under the condition that my mother (and a sister till the time she is unmarried) will have the right to enjoy abode in the house and part of the terrace. That I will be required to pay my mother a percentage of my salary. He also distributed certain other movable items in his will. This witnesses are no longer reachable and their addresses unknown.
The money that we received from his employer on his demise was distributed between my mother and sister based on hard nomination made by my father.
1. Will my sister be able to contest my claim even after I have secured NOC from her?
2. What is the legal standing of my father's will given that its not registered and that the witnesses are untraceable? Can the property be mutated on my name given that my father established certain conditions for me in his will?
3. Can we have a back-dated "family agreement" (between myself, mother and sisters) securing my mother's right to fully enjoy use of this property while she is alive?
4. What kind of evidence is required to establish existence of an oral family agreement?
5. Is a memorandum required in case of oral family agreement?
Also, my mother would like me to give some money from the proceeds should I decide to sell this property even after I have it transferred on my name. Is there a way that can be ensured i.e. to make it a pre-condition to my ability to sell the property despite having full ownership?
