I have been divorced since March, 2000 with full custody of my then 6 yr. old. Support payments were ordered and are garnished from my ex's civil service earnings. The original order read that support continues until age 18. My son will turn 18 this September (2010) but will not finish highschool until June 2011. I read that in this state (GA) support is to continue till age 18 no older than 20 or until that child finishes highschool. My question is since my lawyer did not stipulate only other than age 18 do I have to go back to court to maintain his support until he graduates June 2011?
