Thanks to all of you for your help.
Finally i have decided to appeal at high court by raising below point
1. Family court has not considered my loan liability
2. Family court has not considered dependence of my parents on me
3. Family court has not considered my wife's contribution towards welfare of our child
4. family court believed on the exegeratedexpences shown by my wife.
is this seems ok/. Need experts inputs too.
Thank you
