This is a joint family property and your father had no right to transfer the entire house through a testamentary will. Some facts are undisputed and you have evidence to prove it. The facts are:
- Your grandfather has purchased the land.
- He built a small house thereon.
- His family was residing therein.
- Your father constructed the ground floor.
- You have remitted money in your elder brother’s account for the construction of two additional floors.
- Your elder brother has only one source of income i.e. rental income.
- Elder brother is claiming the entire property because of a testamentary will.
All the above said facts are undisputed. Even your elder brother cannot say that any of those facts is false. He is claiming the right to the entire property because of a will. Now the question is whether your father had the power to transfer the entire house through a will?
The above facts squarely indicate that the house is a joint family property. Your grandfather, father and you have contributed to the building of such a big house. Three separate funds were used. All the family members have enjoyed this property. Hence, it is proved from the facts that the house is the hotchpot of joint family property.

Your father was not a sole owner of this property. Hence, he could not execute a will and transfer this property to his elder son. Since it is a joint family property so all the siblings have a joint ownership. This fact renders the will illegal because the testator had no right to make it.
You should file a declaratory suit and declare your right in this property. You are entitled to get one fourth share in this house. However, you have constructed two additional floors but you cannot claim your title in those floors. You have shown your intention through the conduct that you have brought them in the joint stock of family. Therefore, you cannot claim that it is your separate property.
