Divorce/ maintenance

Hi, Me and My wife both of us are asked to produce salary slips for last 3 months. I believe this is to determine the maintenance for my daughter currently 5yrs of age, not sure? Do I have the right to see the salary slip she submits in court I suspect my wife may produce fake salary slips. Will the court verify the authenticity of the salary slips by any means like…verifying with her employer?? Or do I have right to file a plea to get it verified by the court?? Vipul
