Property dispute

3 months ago

My grandmother is 80+ years and alive, and she has 3 daughters, middle one is my mother. My grandfather had died many years ago and did not make a will for his house, and hence it is understood that the house is now legally under the name of all 4 persons i.e. grandmother and her 3 daughters. Now my grandmother want to sell the house and divide the money between her two daughters excluding my mother. This information was leaked to my mother by a maid servant who used to look after my grandmother 2 years ago. Further, my grandmother along with her two daughters and few other relatives often make up stories and call my mother to provide them a copy of my mother's photo, aadhar, pan etc. required to open a account or payment of tax, etc. But I am 100% sure that they are seeking those documents in order to do some evil manipulation tricks to exclude my mother's name from the property papers and then sell the house and divide the gains. Therefore, I want some advice on how to be safe in such situation and what measures can be taken to protect my mother's legal right to her share in the property. I don't want my mother to suffer losses wherein legally she must get her share in the property.
Looking forward to your valuable advices. Thanking you.
