This discussion clarifies property rights following a release deed executed in 1997. When three daughters released their rights to their mother and another sister (D), the mother inherited a share. Upon the mother's death in 2007, her share devolved equally among all four daughters. A subsequent partition deed in 2007, distributing the property 50% to daughter D and 50% among daughters A, B, and C, is considered valid. To purchase this property, a sale deed executed by all four daughters is required.
