Check the BCFMA's calculations about the jail time you face
Your enforcement order will say how many days in jail you must serve for each missed payment. Multiply the number of missed payments by the number of days listed to find the total days you might have to serve. The maximum you'd have to serve is 90 days.
For example, suppose the enforcement order states that in addition to your regular maintenance, you must pay $100 per month starting March 1, "and in default of each payment as ordered, you will be imprisoned for a period of 3 days consecutive per default." That means that the court will want you to serve 3 days in a row for each missed payment. If you have missed 10 payments, then you will be facing 3 x 10 days, or 30 days.
If you think a mistake was made in the calculations, or if you weren't credited for payments that you made, you'll need to prove this at the hearing. You can ask for more information about the BCFMA's calculations at the first hearing.
Keep in mind that when you make a payment, the money goes first to regular maintenance, then to arrears (back payments owed), then to interest and fees. That means that if you made partial payments that didn't cover the entire amount of regular maintenance plus arrears, you would still owe money.
For example, if your default order says that you must pay $100 per month in arrears, and you owe $300 per month in child support, the total payment owed per month is $400. If you paid $350 one month, the first $300 goes toward regular child support, and only $50 goes toward arrears, which means you would still owe $50, or half of your arrears payment for that month.
