New asset purchased in another person's name. Whether exemption u/s 54F available?

I sold a plot which was in my name.
The sale consideration was 15 Lakh and invested entire sale consideration in a residential house (By way of repayment of Housing Loan taken 3 years back and re starting the new house construction work) which completed the entire construction within a year of sale but construction started 4 year back by taking Housing Loan from Bank.

However the new residential house is constructed in the name of my Sister.
But we all are staying together in the new house.

Whether I'm eligible for claiming exemption u/s 54F or not ?

If yes do I need to file the return or not ? I'm not having any other income.

Please someone help me !
