A person signed a relinquishment deed in 2009 after their father's death, at the request of their uncle and brother, due to their upcoming marriage. Unbeknownst to them, their mother's name was also removed from the property card at the same time. The brother then sold the property in 2014 without the mother's knowledge. The core issue is whether the mother can challenge this sale and reclaim her share, especially given the time elapsed since the deed was signed and the property was sold.
