Can Agricultural land can be purchased without Partition deed

Respected Advocates, I am planning to but 12000 sq ft Agricultural land from Mr. A in Mulshi Taluka , Pune District. Details of the land . Survey Number :- 38 Taluka :- Mulshi District :- Pune Owner of survey no 38 :- Mr A, Mr B and Mr C having share of 12000 sq.ft , 17000 sq.ft and 40000 sq ft respectively. Mr A is selling the land to me , he has fenced 12000 sq ft and have constructed a house in one part of the survey no. 38, He has also registered the house in Gram Panchayat and have taken the electricity connection. I have asked him for the partition deed between A, B and C . Mr .A said that no one is ready to make partition deed. He told that before doing the govt. survey ,notice was send to B and C and they didn't came so he himself took the possession and have fenced the property. I have also searched all mutation and sales deed till now but no partition is mentioned in it. Query 1) Is it safe to buy land and house from Mr A as no partition deed is made.? 2) if i purchase the land then Can Mr. B and Mr. C can create trouble to me as no partition deed is made among the all owners of the land.
