With all due respect, how do you expect your ex to pay from inside a jail cell? To get a job so he can pay if a potential employer sees him labeled as a “deadbeat dad” who is likely to go to jail again soon?
Or does he have the money and just won’t pay? In that case, lock him up.
Please re read my post. I said that I agree that in most cases jailing them is counterproductive. He will work for awhile and then as soon as the courts catch up to him he quits. He works cash jobs under the table. He has several years of income tax he has refused to file for because the court would seize it.
