Claim on property under our possession but documents are with cousins

Hello sir , My father and his brother bought a property in 1992 area of 1500sq feet . As my father was younger he kept property paper on his name only. We have been living in the house since it was made and constructed further . They have been never lived here but taken home loans once in 2005 . At the time of loaning process they said to do registry of house to my moms name . As all the loan were paid and we asked them to transfer paper of house they denied . So what can we do to take proper ownership of house. Electricity bill and gas connection is on my name . We live here as the owner of house but we dont have any name on property paper. Is my case could come under adverse possession. Thanks in advance
