3 yrs old daughter awarded 22K as Interim Maintenance.

In DV case, 3 yrs old Daughter awarded maintenance as 22K (1/3rd of my salary) but wife also started earning now. She is earning 28K now. She started working after 2 months of interim maintenance order. At the time of filing DV, she was working and earning 34K. Given all those documents to judge but lady judge ignored all. Can we file perjury for that as she had written at the time of filing " UnEmployed and household lady" at the time of filing DV? Appeal rejected in Session Court for reduction in maintenance. Please suggest what to do ?
