Name changed in america-accepted during property sale?

• We had bought a property Before marriage on my name as "Gita Chandar" (name before marriage). 
• We had bought another property After marriage on my name as "Gita Suresh Das"  (name after marriage). 
• Recently I had changed my name to "Gita Chandar Das"  (just changed the middle name). 
• Both Name changes were done in  America and I have the name  change documents from a America court ofice.

Please advice on:

1. Will I have any problems while selling both the property above? 
2. Is it enough if I just submit the name change documents that I had received from American court? 
3. Should I still change my name in India also? 
4. Should I change my name in the property documents also or  is it enough if I submit the name change certificates? 

Thank you,
