Hindu Ancestral property registration doubt

Hi Sir, I am a lady who is 30 years old and married living with husband and 5 year old kid. My mother wants a help from me to save our house from debt. She needs 5 lakhs to release the documents from the bank. The property is 15 cents and a house. This property is my grand fathers( mother's father) property given to my mother while partition and was registered in both my mothers and fathers name. My father passed away in 2015. I have an irresponsible elder brother who has not been working or trying to clear the debt for nearly 5 years. We have given him lakhs multiple times but everything was in loss. To be on the safer side this time, I told my mother to register the property in my name after clearing the debt and getting the documents from the bank. Now my mother and brother are ok to this. However, they may change their mind and claim for the property later. We seek your advice on how to register this property in my name completely so that nobody can claim it later
