Raising children in two households is one of the biggest challenges faced by parents after separation or divorce. Parents who are used to letting their spouse be the disciplinarian have to step up and be the "bad guy" occasionally when their kids are with them. Another challenge is that you and your co-parent likely don't have the same parenting styles.
Missouri, like other states, has a number of methods for getting child support from parents who are not making their payments as ordered by the court. One of these is taking people's occupational licenses. Here in Missouri, a person who hasn't made child support payments for at least three months can lose their commercial driver's license (CDL) or other professional license.
