It depends on what the child support order says. The typical child support order in Washington says that child support ends after the later of the child reach age 18 or graduating from high school, unless there is a timely petition for post-secondary support. If she is pregnant, let's assume that there is no petition for post-secondary support. Since she is already 18, the only remaining criteria is high school. If she graduate next June, then, June, 2012, would be your last month to pay child support.
