TRANSFERRING OF PROPERTY FROM MOTHER TO SON

ear sir, My mother want to transfer her property (house) to me for which construction loan installment has been paid by me every month from last 8 years. Now my brother is raising issue and asking share in the property but my mom want to transfer the same to my name. I wanted to know whether my mom can transfer the property without my brother sign or clearance, if transferred to my name whether serious legal issue will raise on me or on my mother. Please provide me the solution
