It can take some time to get a modification of child support petition through the court system. Depending on the county you are filing in you can expect to wait at least 45 days for a court date, and most likely you will have to wait longer. If the other side is cooperative, then you can always get things done faster by consent of both parties. However, if the other side is likely to contest the child support modification, you will have to file discovery requests to get accurate financial information from the other side and give them at least 30 days to respond. Bottom line, expect to wait at least 45 days, and most likely longer, until everything is processed depending on the county.
