Your opening sentence answers the question. The law is very clear - if the request for post-secondary education is not made before the child is emancipated, the court loses jurisdiction over the child, and you cannot be ordered to pay. It looks like the mother's deadline to file in this case was last June. Of course, nothing prevents you from helping her out from time to time as you see fit.
