I'm allowed to request a modification every 6 months. They send him a paper asking him what his bills/expenses/income. Then it takes 30 days additional to for the C.S to review then another 30 days to get back to me. 30 days for his employer to submit the c.s.
By then its time for another modification. If he leaves a job, I have to contact him his wife to get the information where he works. He won't do it she won't do it. But THEY love my kids.
