My new wife and I have four children between us. "Our" youngest had decided to stay in Pittsburgh with one of the wife's relatives while we moved away. For two years we had sent $300 a month to help with the boy's expenses. This month he turned 18 and we felt that we had fulfilled our obligation and didn't send any money. We have had no discussions with the relative since the last time she called and asked for more money! Today we received a threatening phone call from the relative stating that she would actually take us to court if we didn't continue paying! We are curious if this is even possible and how it would work. Anyone?
