Without seeing the agreement it is difficult to answer your question. However, as a general rule, unless there is a court order establishing custody, such an agreement would not be binding. The other question is how old are the children now. Your question says the agreement was in 2002. If any of the children are over 18 the agreement would have no effect on them. You should have the agreement reviewed by an attorney who could then provide more solid advice.
