First, what type of divorce are you seeking? If you are seeking a divorce based on irreconcilable differences, there is a minimum statutory waiting period. This is basically a cooling off period that starts to run when the complaint is filed with the court. If the couple has an unmarried minor child, the waiting period is 90 days. If there are no children, the waiting period is 60 days. In order to get a divorce based on irreconcilable differences, both husband and wife have to agree on all aspects of the divorce.
If you are seeking a divorce based on grounds other than irreconcilable differences, there is generally no statutory waiting period. However a contested divorce by its very nature takes time and money. Contested divorces can take years.
Note: Grounds for a divorce are:
(1) Impotence; (2) adultery; (3) conviction of a felony and imprisonment; (4) alcoholism and/or drug addiction; (5) wife is pregnant by another at the time of marriage without husband's knowledge; (6) willful desertion for 1 year; (7) bigamy; (8) endangering the life of the spouse; (9) conviction of an infamous crime; (10) refusing to move to Tennessee with a spouse and willfully absenting oneself from a new residence for 2 years; (11) cruel and inhuman treatment or unsafe and improper marital conduct; (12) indignities that make the spouse's life intolerable; and (13) abandonment, neglect, or banning the spouse from the home.
