phone bill as evidence for extramarital affair

Child custody is decided by the court only on the basis of the welfare of the child.

That the mother is talking to her boyfriend for longer hours is not a matter to be considered while taking a decision on child custody.

I agree with expert opinion and advise of Mr. K Rajasekharan, custody of minor has no concern with chatting of .your wife with her boyfriend.

Can you prove her extra-marital  affair through alleged long chats ? However, long phone chatting is no crime. 

Are you a subscriber of that connection?  If the bill is not in your name, getting such bill in your name brings problems to you and also to service provider.   Thus you are not getting any edge but purchasing more problems with such bills.

Why you are posting facts in piece-meal. Please post complete facts bringing out the real issue, if any.

Moreover, it is not necessary that the person your wife is in contact is not be a boy friend  and a mere telephonic contact need not amount to or constitute extra-marital affair.
