Purchased property in mothers name does sister have any claim in it

Religion : Hindu Sir, I purchased a property(new flat) in 2003 in chennai, and register in my mother name. Last year, my mother executed the gift deed and transferred the same flat to my name. When I sell this property in future, do I need to get any concern from my sister? Me and my sister are the only child to my parents. As of now the relationship is good with my sister, but not sure how long this will continue. If I need to get a concern, Can I get that concern/document signed from sister now, so that I can use it whenever I sell this property? Thanks for your help.
