My common-law ex and I split up a just over a year ago. Each of us has custody of one of our children. I don't make much more than she does, but she's hinted that support might be an option for her at times and that she might pursue it legally. When is it customary to seek support in these types of cases? Right after a split? Or could she reasonably file 5 years down the line? Or would a lawyer or a judge simply tell her that that ship has sailed?
