False civil suit

My father purchased properties from his mother's sister. My father had written a will for me , my brother and my sister in law assigning some properties. All properties are of self acquired by my father. My brother got 5 cents extra house land and he did not get any share in old family house. Actually his share value in the family house is lesser than what he got 5 cent extra. I and my mother approached my brother after my father's demise to partitions of the property through my father's will. He got and read the will. Afterwards he sent legal notice to me, my mother and widowed sister in law that my father did not write any will and filed civil suite in sub court Aruppukottai in tamilnadu. In the case my brother has said that the property he got is only of our father's self acquired and other properties written to us by my father is not self acquired, it is ancestral and has to be given to all our sisters. I defended this case with my lawer for 10 years and my brother finally agreed my father's will. Now my brother is no more. How can i get remedy for spending waste money please reply
