yes

The obligation to pay child support ceases when the child turns 18. The only exception to this is if the child is disabled with special needs; if the child is unmarried, a dependent, under 22, and in post-secondary school; or if the parent agreed otherwise. Thus, it is possible. Addendum: Actually, there is one more exception. Nearly every state extends support obligations past 18 if the child is still in HIGH SCHOOL. As for the answers that say support past 18 is the norm, this is simply not the case. 38 states have laws that say child support ceases at 18 (or after high school). In Pennsylvania, their supreme court found that it is unconstitutional to require divorced parents to support a child past eighteen. They reasoned it would violate equal protection to require divorced couples to pay support past age 18 when married couples did not have the same requirement. The remaining states don't mandate that support last through college. Rather, they give the court discretion to award support when deemed appropriate. In all states support can continue past age 18, but it cannot necessarily be imposed. Rather, many divorce decrees have an agreement that support will continue through a specified age.

Yes..most child support orders continue past the age of 18 if the child is enrolled in college full time :)
