Thanks. We actually went to the facilitator earlier today. The county was able to answer some basic questions and this particular woman was very nice, something I definitely wasn't expecting.

The answer to my question, for anyone else in a similar situation, is that a stipulation must be signed by both parties (notarized) then signed by the judge and filed with the court

Obviously the spouse is benefiting from "temporary" spousal support, so why would she sign something to voluntarily end it?
It has been 9 years since the divorce. She was ordered to get a job as to "lessen the support obilgation and eventually become self-sufficient". The marriage length was 11 years. The spousal support was never lowered.

We know she may not volutarily give up support, however we're trying to be nice. If she says no, we're going to begin the battle.
