From the date we saw my attorney, three months. It only took that long because Franklin County has a mandatory waiting period once the paperwork is filed before the case is heard.
Unfortunately, I disagree with Damreds in the post above. Have an attorney do it. A dissolution requires by law that only one spouse can have legal representation, both is considered contested. It's very inexpenseive and honestly, saves you a lot of headache and footwork. Papers are still drawn up, as mine were 3x pages long because it still names who gets what, finances, etc.
Get an attorney, just make sure she agrees not to get one as well.
