If you seek a nofault divorce , you'll have to wait the 18 months . You can sue for divorce ( or be sued yourself ) under any of the fault grounds without waiting . The fault grounds are ; impotence; adultery; confinement for incurable insanity or separation caused by mental illness for a period of 3 years; conviction of a felony; cruel and inhuman treatment which endangers the life of the spouse; personal indignities; habitual intemperance (drunkenness) for 1 year; commission and/or conviction of an infamous crime; and nonsupport whereby the spouse is able to provide support but willfully fails to provide suitable maintenance for the complaining spouse.
