1) Can the court award maintenance under GWA for the children? Is it allowed or normal practice to order maintenance under GWA act? If yes, then what could be the amount and how is it calculated. Children are 6 and 2 years of age.
Who is seeking maintenance under GWA act?, If the father is seeking custody of children under GWA act, has the wife filed for maintenance for children? Because she can claim maintenance even otherwise by imposing provisions of particular law for maintenance. There is no normal practice to allow maintenance even before it is sought before court.
2) if the father refuses to divulge his payslips/income (or income tax returns) then is it a problem? NO.
Can he show his immovable properties and retirements benefits (EPF & PPF) to prove he has sufficient means than the wife and in-laws. YES.
Can the court force him to divulge his payslips or IT returns which is very personal thing. NO, court cannot force the situation.
