There is no way any interim application for child visitation filed under section 125 Cr.P.C.
An Independent petition under section 25 of the Guardians & Wards Act read with the Hindu Minority & Guardianship Act,1956 has to be filed by you in the Family Court seeking the custody of the children as you being the natural guardian and custodian of the children, the wife had removed the children from your lawful custody without your consent hence you should be handed over their custody. An interim application for visitation for children can be filed along the main custody petition that Family Court will allow as you are the father and natural guardian of your children.
This is the way the case for child custody and visitation should be worked out and not the way your advocate is advising, better check if he has any experience in handling the Family Cases.
