Yes, you may file a civil suit for claiming your share out of ancestral property. There are two options:

a) if the left over property is enough to cover your share, you may claim out of that; e.g. if the total value of ancestral property was one hundred, your share comes to twenty five; the value of sold property is fifty; then you may claim your twenty five out of the remaining fifty by seeking a declaration that whatever was sold should be deducted out of their share;

b) if the value of left over property is less value of your share, you may seek cancellation of sale deed.
