Can a release deed be cancelled claiming that one signed without reading deed ?

2 years ago

Below are the details of the property partitioning made between me, my mother and my younger sister. Properties: A two storey house under my father's name ( my father died 11 years ago) - lower level built by my father ( my mother lives here currently ) - 1st floor built by me after ( me, my wife and my kids live here ) There were two lands and a commercial building under my mother's name. I took the house and the commercial building through a release deed from my mother and sister. I accepted to allow my mother to live in the lower level all her life. My sister took the two lands through a release deed from me and my mother. Later, she had sold the lands. Now, my mother, sister joined hands and filed a suit with my mother as plaintiff claiming that she did not read the release deed of transferring the house to me, as she trusted me. She stated that she also believed that the deed was actually containing the details of equal partitioning (1/3 for each) between her, me and my sister. She has also claimed that the 1st floor building was constructed by my father. Will the court accept that my mother signed the deed without reading since she had trust in me?
