Husband's family harrassment

A compromise decree took place In between brothers and mother of my husband and 4 equal shares of ancestral property were given including one share in my husband's name. Last brother is dead and his wife took her husband's share and went separate and is living happily. But my husband's share was with held by his mother and elder brother an all the benefits were taken by them even though they took control of there shares. Being a legally wedded wife, I went with my husband requesting them to leave our share to my mother in law as I have a daughter to look after(inspite of I knowing that wife does not have any right's over husband's property). Mother in law refused and my husband kept quite as he was shy and thought it will hurt his mother. To ask, I had gone to mother in law's house (the share which she got ) where her first son and his family stay. All of a sudden my husband's brother and his wife started threatening that they will lodge a police complaint against my husband and me that why we have entered their house. I have recorded all the conversation and felt sad that my mother in law actually supported her first son and she said, she will not give control of our share till the time she feels like not giving. I was upset and came back with husband.
