What is the name of your state? IL. My husbands oldest son turned 18 in january, graduated high school in April, and moved out of his mothers in june. The divorce agreement says we are responsible for 100% medical on the children until each child is immancipated. says immancipation is turn 18 or graduate high school, whichever is later. My question is this: do we have to go to court or can we just notify the providers in writing that we are no longer responsible for his medical expenses? I know the wording is important (because the wording screwed us on the child support). It says "the parties respective obligations under this article shall commence upon the effective date of this agreement and shall continue, as to the minor children, until the emancipation of each child, as herein deifned. (18 or graduation whichever is later, maintaining a full time residence outside the home....) on and on. Can I just send the providers a letter? thanks.
