Maintenance of wife and child

Mr. Varun, 

A wife cannot both live in a separate residence without fulfilling conjugal obligations and claim maintenance unless she has legitimate reasons to do so. However, you are bound to maintain your child under law, under any circumstances.

Thanks

Though you are logically and legally right in contending to your wife  that she will not be entitled for any maintenance by you if she had voluntarily abandoned the matrimonial without any valid reason, in your letter you should have quoted the wordings this way as I have said above, and also should have mentioned that the entire fault lies on her to stay away, in any case you cannot give a blackmailing letter this way that is she is not returning you she will not be entitled to anything from you, this will turn against you and will be considered that you have actually tortured her hence she left your company.  Take the help of a local lawyer for the legal complications that may develop due to this in the near future.
