Dear Experts
My Father Mr.A as karta of HUF of our ancestral property had Execute a registered GPA without any monetary consideration in the name of Mr.B and at the same time also executed registered agreement to sale in the name of Mrs.C (wife of Mr.B). Both were executed in 1990. Some payment was due to be paid to my father at the time of these agreements which Mrs. C need to pay at the time of sale deed registration. GPA was given to do all acts to complete agreement to sale on behalf of Mr. A. Mr. B, the GPA holder did not execute sale deed in favour of Mrs . C for long time. and finally in 2007 he executed & registred sale deed in favour of his wife Mrs. C. without informaing my father and did not give the balance payment to my father which was due at the time of agreement to sale. Now he says that balance payment he had deposited in MCD house tax department as the house tax was due at the time of GPA and agrrement to sale i.e 1990. He is also not showing the house tax payment receipt. we came to know about this sale deed few months back.
So please suggest what legal step can my father take against him. Can i being the member of HUF claim anything from this as i was minor at the time of GPA.
