It depends on the individuals & how willing they are to cooperate.
I've had 2 lots of counselling (xh wouldn't do alongside me had to be separate), 1 mediation process (he agreed to a lot & then pulled out & changed it all when it came time to sign the papers), judge led mediation where XH still wouldn't agree & ended in a court hearing with judge ruling outcome.
I think if you think you could possibly agree then go for it but if you think he will change his mind a hundred times then skip all the mediations & go straight to the end to avoid a long drawn out court process (mine took 1 and a half years!)
Best of luck.
