Its probably just a kit to file pro se, but if you really want to go that route you don't need a kit to file pro se. There are people who DIY their divorce. However, if you are trying to get out of alimony or CS couldn't she just hire a L down the road and come after you? Also some judges may not rubber stamp your D if it doesn't look right esp with kids involved. I don't know, and I am guessing you probably don't either. That's why a consult with a L is a good idea.
