LTCG shared between family members

Hi, 

My father in law(now expired) had a property for which current surviving legal heirs are my daughter and my sister in law .. 

My sister in law(with our consent) had sold the property in January this year and transferred the half of the sale proceeds to my daughter's account. 

My daughter's name doesn't reflect in registered sale deed and no direct payment is recived from the buyer.

I need to file or can I file income tax returns showing capital gains under my pan as my daughter is minor. 

Since we have received the proceeds can we file itr under my name or only my sister in law has the right  file the itr...
