Filing for divorce when your spouse is out of state depends on two factors. You must have legal residence in the state where you're filing, and you must be able to serve your spouse with a copy of your divorce papers. Maryland is one of the more lenient states for service of process of divorce papers if your spouse lives elsewhere.
Determine your grounds for divorce. Maryland offers two sets of grounds, one for a limited divorce and one for an absolute divorce. A limited divorce is akin to a legal separation. If you want to end your marriage completely, you'll have to file on grounds of adultery, desertion, cruelty, excessively vicious conduct, conviction of a crime, insanity, or the no-fault provisions of a voluntary or involuntary separation. All grounds except adultery, cruelty and excessively vicious conduct include waiting periods.
Establish residency in Maryland. There's no waiting period for residency if your cause of action, or grounds, happened in the state. For example, if your spouse committed adultery or engaged in cruel or vicious conduct while you lived together in Maryland, you can file for divorce immediately. If your grounds occurred elsewhere, such as when you and your spouse were living in another state, you must reside in Maryland for one year before you can file. Your residency time and the waiting period for your grounds can run concurrently.
Access a form for a Maryland complaint for divorce. Forms are available from the Circuit Court clerk in any Maryland county, or from a third-party legal document service. The form only requires you to fill in your personal information. If you want the court to order child support or alimony, you must also request and complete a statement of your income and expenses.
File your complaint with the Circuit Court in the Maryland county where you live. If it would be more convenient for you to file in the county where you work, you can use this Circuit Court instead.
Serve your spouse with a copy of your divorce complaint and a summons, which you can also get from the court clerk. It's usually available within 10 days of filing your complaint. Maryland law allows you 60 days to accomplish this, or you'll have to request a new summons from the court. Maryland allows service of process by certified mail, so you can simply mail a copy of your paperwork to your spouse. If he doesn't sign for the mail, you can hire a private process server in the state where your spouse lives, or contact a sheriff's department there to find out if that state provides service by a sheriff's officer. Maryland doesn't allow you to hand-deliver a copy of your divorce papers to your spouse yourself.
