What does a true-up mean?
When you or your ex-spouse’s income fluctuates, i.e. a salesman with a base salary plus commission, you will often hear that a “true-up” is necessary at the end of each quarter or year. If there has been an over or underpayment, you “true-up” at that time. As part of the process, all income information is exchanged, and the accurate child support (or maintenance) sum is determined. Documents involved usually include W-2s, 1099s, K-1s, tax returns, and bank statements; both personal and business records.
