In Alabama, you can seek a “no-fault” divorce, meaning you can dissolve your marriage without any other reason except that your marriage is “irretrievably broken”, or that you have been separated from your spouse for at least two years. There are also various “grounds” for getting divorced; such as adultery, cruelty/abuse, incurable insanity, and some others.
In general, “no-fault” is the easiest and smoothest way to get a divorce. If you file based on one of the fault grounds, you will need to prove to a court that your spouse engaged in misconduct and/or displayed some type of behavior that legally justifies the dissolution of the marriage. This is more costly and time consuming and is not usually recommended except in some limited cases.
In order to file a complaint for divorce in Alabama, at least one of the spouses must have been a resident of the state for six months prior to the filing, and this must be alleged and proven within the complaint. There is also a 30-day waiting period after filing the complaint before the divorce may become effective.
