Double document

My maternal grand father, registered his lands to myself (son of his daughter) and to my uncle (his son). For me 10 cents of land has been registered subdividing from 80 cent land and to my uncle only 70 cents from that 80 cents land has been intended to be registered. But my uncle during registration, somehow forged us and printed 80 cents fully in his document. Both lands has been registered on same day same time and my document has been registered first and followed by him as second. Also, my mother signed his document as witness unknowlingly about this problem on the advice of my uncle and also my uncle did not sign in my document for any kind of witness. Document writer and sub registrar also missed to note this before registration. Now, in my document 10 cent is there mentioned with subdivision and in his document also he added that 10 cents. What type of civil or criminal cases can I file to solve this problem? or any other steps can be taken to resolve this issue without seeking court?
