10gunta land was partioned to my father family members (not ancestors property but was purchased by my father and uncles) each getting 2 guntas and each have their updated RTC and patta updated. But 2gunta was given to 1 family with 2 brother's in 1 single deed (joint ownership for 2 guntas). Both the brothers name is reflected in the RTC but only the 1st brother name in patta book. Now I want to purchase 1 gunta land from the 2nd brother as he needs money and want to sell his portion of land. How can I purchase this land so the 1st brother would not create issue in future. Also since patta is not bifurcated will this create issue. Can we purchase the property without the 1st brother signature as i am not purchasing his portion of property. Please help as I don't want to loose this land as the land was purchased by only 2 people, by my father and uncle but being partioned to other 3 family because of other family commitments, who paid zero but expecting many lakhs to sell.
