I'm considering divorce with my wife.

I'm just wondering how child support demands work for freelancers. I have some months without incoming payments, some months with little, and some months with more than enough to cover up for the former two. Fluctuating economy. My wife, however, has an outstanding job.

How do people in similar situations deal with child support. What happens if you miss a month? I have no idea about this at all. What are realistic worst case scenarios? Do I run the risk of having the police show up at the door?
