Can daughters claim property rights after 14 years? Legal actions?

I purchased land in 2008 from three sons, although the ROR was still in the name of their father, who had died in 2004. Now, after 14 years and converting the land to Gharabari, I discovered he had three daughters, which the sons hid. I asked for the legal heir certificate, but they refuse to share it. In 2019, they mutated other properties in their father's name without the certificate. (1) Can the daughters still claim rights after 14 years? (2) Can a lawyer send notice to demand the legal heir certificate? (3) Can a lawyer question the Tahsildar for mutation without the certificate and challenge it? Please guide me.
