Maintainence

My wife file case under sec 125 for maintainence for her and 3 months son in April 2015. She was not working that time. During pendency of case she got govt job. Interim maintainence order was passed on Nov 2017 she was awarded Rs. 5000/- and Rs. 7000/- to son. She further filed case under sec128 for recovery after three months. I have not paid any amount till date. I am working in govt sector. The case is in Chandigarh and I am working in Lucknow, so not possible for me to come to court every time. Now judge in district court is pressuring for maintainence. He had issued conditional warrant for arrest under sec 128 in March, but I could Not attend court as my grandfather expired . He again issuedconditional warrant for arrest under sec 128 but I could not attend court as my father attended. Judge pressured to give maintainence backlog min 1 lacs. I learnt from web that sec 128 judge cannot punish u for not paying backlog, he can only ask for paying of maintainence in current. Whereas for maintainence arrears one has to file execution under sec125. My query is that- 1. Should I pay 1 lacs or make excuses in court. 2. If I make excuses can judge give arrest orders 3. Or should I start paying maintainence from current time. Pls guide
