You are required to pay child support until the child is deemed emancipated under Missouri Law. A child will be considered emancipated when the child does any of the following:
1. Reaches the age of eighteen (18) or graduates from a secondary school, whichever occurs later, unless the child is attending an institution of vocational or higher education, in which case the support obligation shall continue until the child completes said education or attains the age of twenty-one (21), whichever occurs first
2. Dies
3. Enters into marriage
4. Becomes self-supporting, provided that the primary custodian has relinquished custody of the child by express or implied consent
5. Enters active duty in the military
There are additional statutory requirements placed on the child if he or she enrolls in higher education. These specific requirements should be discussed with your attorney.
