This property that i am staying in was initially under my mother in laws name n she passed away a couple of year's back making a will stating that this property after her death would be under my husband's name 1st and then youngest son. Now my husband passed away in 2012 n he didn't make any will or an legal paper's to transfer his share under my name. Now my brother in law (the half owner of this property as per will) is refusing to transfer the papers under my name. And is forcing me to stay in this house like we r his slaves which i don't want anymore. I do not have the agreement paper's of this property he has it , i jus have the Share certificate original with me. He wants half share from this property where in he is a very financially settled guy n works in Merchant navy as an chief engineer. I do not wish to give him any share from this house as i am legally staying here n paying all the maintenance bill's etc. I want help in this matter kindly help. My email is [deleted]. kindly revert asap please i need help my son who was in merchant navy is not working due to medical conditions n my divorced daughter is also home n not working.
