My ex-husband and I have mutually agreed upon child support for the past 4 yrs ... we now have a daughter who will be turning 18 in Oct, who is also pregnant, she also has 2 yrs of high school left before she graduates ... he is now telling me that he no longer is required to pay support for her because she is pregnant and considered an adult now ... I always thought that he was obligated to pay support for her until she graduates ... can someone help clarify this for me ... we live in PA
