Our state doesn't call it a collaborative divorce, but it sounds like what H and I are doing.
Basically we got together without our lawyers (actually H isn't even getting a lawyer) and we wrote up what the two of us agree to in terms of finances, kids, possessions, etc. I sent the draft to my attorney. He will review it to see if it is 'fair' to both parties. If so, my H and I will sign off on it and it will go before a judge. Unless the judge thinks one of us is getting screwed, he will grant the D with our terms.
No fuss, no muss, just ripping a family in half and dissolving a marriage. (OK maybe a little bit bitter here...)
