(1) Mr. Popat was a Indian Christian and he had 4 son & 6 daughters. (2) First, Popat sold that 31.25 sqm ancestral property (out of 125 sqm) to one of his son Mr. David on 17 Oct 2012 which I have purchased on 24 Feb 2015. (3) Second, Mr. Popat sold 31.35 sqm land to one of his son David on same day i. e. 24 Feb 2015. Mr. Popat passed away on 13 Nov 2016 then again Mr. David sold this 31.25 sqm land to me on 25 Jul 2017. My name has been recorded to Land record office for 62.50 sqm land. (3) Late Mr. Popat's 6 married daughter's are saying that Mr. Popat made registered Will on the name of his 6 married daughter's for the same property, Hence, David's sister's want back this 62.50 sqm land and also threatening me for that. Now, my question are as follows:
-Sale deed's between Popat & David held in Oct 2012 & Feb 2015 is valid -Sale deed between David & me held on 24 Feb 2015 & 25 Jul 2017 is safe as per law -If they have WILL then any problem for me -Is it ancestral property? If they file suit then it will create problem for me.
