1) you had raised this query earlier too which had been duly replied to .
2) in the present case there is no formal deed of adoption executed by father Y in favour of F and W2.in respect of son S 5
3) however in school college records of S 5name of parents is shown as F and W2.
4)To prove valid adoption, it would be necessary to bring on records that there had been an actual giving and taking ceremony; M. Gurudas v. Rasaranjan , AIR 2006 SC 3275.
5)in addition section 11(1) of HindU adoption and Maintenance act 1956 provides that for adoption to be valid adopted father at time of taking in adoption must not have a hindu son living at the time of adoption .
6) in the present case adopted father already had a hindu son S1 from W1 and another son S 3 from W2
7) hence merely because S 5 was lving with F and w2 would not be sufficient for s 5 to be regarded as adopted son .
8) F and W2 can execute gift deed in respect of their self acquired property to any one they so desires . it is not necessary for w2 to give any share to s1 , S 3 and S 5.
9)claim of son of S1 is not valid . father and W 2 can transfer property to S 5 by gift deed even if he was not adopted out of natural love and affection
10) S 5 will have to move court to set aside gift deed executed by son of S1 in favour of his son as the S1 son had no rights on said property which had been transferred to S 5
