Legal Question in Family Law in India

yes, in case he is able to prove that the mother of the child is unable to take good care of the child and he can take a better care.

I do not agree with the above opinion.

Yes he is entitled to custody of a child even below five years. He does not have to prove that she is unable to take of the child or that he will take a better care. However, the courts may not go into the "rights" of the parties but decide the custody issue keeping into mind the "welfare of the child".
