What Are the Grounds for Divorce in Maryland?

To file for divorce in Maryland, you must state a legally recognized ground — the reason a court accepts as sufficient to end or legally separate a marriage. Maryland recognizes both absolute divorce, which permanently dissolves the marriage, and limited divorce, which is a court-supervised separation without full dissolution. The ground you choose affects how soon you can file, what evidence you need to present, and in some cases, how the court approaches alimony and related financial issues.

This article covers every recognized ground for divorce in Maryland, explains which ones are actually used, walks through what each one requires you to prove, and clarifies how your choice of ground can affect other outcomes in your case.

Absolute Divorce vs. Limited Divorce in Maryland

Understanding the difference between these two types of divorce is the right place to start before choosing a ground.

Absolute divorce is a complete, final dissolution of the marriage. It ends the legal relationship, allows both parties to remarry, and gives the court authority to divide marital property, award alimony, and put custody and child support arrangements in place.

Limited divorce does not end the marriage. It functions more like a court-supervised legal separation. A court can address custody, use of the family home, and financial support during a limited divorce, but the marriage continues and neither spouse may remarry while it is in effect. Limited divorce is most useful when one spouse needs a court order for support or custody quickly but the couple does not yet meet the requirements for an absolute divorce.

The grounds available for each type are different. They are covered separately in the sections below.

Grounds for Absolute Divorce in Maryland

1. Twelve-Month Separation (No-Fault)

The 12-month separation is the most widely used ground for absolute divorce in Maryland. No fault is required. You do not have to prove that either spouse did anything wrong. You need to show that you and your spouse have lived separate and apart, without cohabitation, for at least 12 continuous months before the date of filing.

Can separation count if you still live in the same house?
Yes, in some circumstances. Maryland courts recognize that financial hardship sometimes makes it impossible for spouses to maintain separate households. Living under the same roof can still qualify as separation if the parties have genuinely stopped living as a married couple — meaning separate bedrooms, no shared marital routines, and independent personal lives. Courts look at the actual conduct of the parties, not just the address on a driver’s license. This is a fact-specific question, and the answer will depend on the specific circumstances presented.

What you need to prove: Testimony from at least one spouse is typically required. Courts often look for corroboration from someone who knows the couple well enough to confirm the separation has been continuous. No showing of fault, financial hardship, or a specific reason for the separation is required.

This is the ground most Maryland practitioners recommend for uncontested and moderately contested divorces. It removes the need to present either party’s personal conduct in open court, which tends to lower litigation costs and preserve co-parenting relationships. If you are working toward a Maryland divorce and want to understand how the process fits together, starting with a clear plan makes a real difference.

2. Mutual Consent (No-Fault)

Mutual consent is the fastest path to an absolute divorce in Maryland for couples who can reach a full agreement. It is available to couples who either have no minor children together, or who have minor children and have reached a complete written agreement resolving every contested issue, including property, alimony, custody, and child support.

There is no waiting period. You can file as soon as the written settlement agreement is signed by both parties. Neither spouse may seek to set that agreement aside at the time of the divorce hearing.

What you need to prove: The signed settlement agreement is presented to the court. Both parties must confirm on the record that the agreement is complete, voluntary, and final. Courts typically require both spouses to be present at the hearing.

If you are working toward a full agreement, understanding asset division and spousal support issues ahead of time helps ensure nothing important is left out of the settlement.

3. Adultery (Fault)

Adultery is a fault-based ground for absolute divorce. There is no waiting period — you can file immediately — but the evidentiary bar is higher than in a no-fault case.

What you need to prove: Direct evidence is not required. Maryland courts have historically accepted proof of adultery through two elements: that the other spouse had the opportunity to commit adultery, and that the other spouse had a disposition to do so. Circumstantial evidence — such as proof of a close relationship with a specific person, time spent alone together, or communications between the parties — is generally admissible. An admission by the other spouse may also be sufficient.

Does adultery affect the financial outcome?
Under Maryland law, fault can be a factor when a court considers alimony. A court may weigh adultery when deciding whether alimony is appropriate and in what amount, though it is one of several factors and not determinative on its own. Fault generally does not directly control how marital property is divided.

In practice, pursuing adultery as a ground raises litigation costs significantly, exposes private conduct in public court records, and often harms co-parenting relationships. Many Maryland practitioners advise clients to use the 12-month separation ground even when adultery has occurred, unless alimony is heavily contested and fault evidence is likely to make a material difference to the outcome.

4. Desertion (Fault)

Desertion occurs when one spouse deliberately and continuously abandons the marriage without the other spouse’s consent and without justification. To use desertion as a ground, the desertion must have continued for at least 12 months.

Maryland recognizes two forms:

Actual desertion means one spouse physically leaves the marital home and refuses to return.

Constructive desertion means one spouse’s conduct in the home — such as persistent cruelty or refusal of marital relations — is severe enough that the other spouse is effectively forced to leave. In that situation, the spouse who left is not treated as the deserter.

What you need to prove: The departure must be deliberate, unjustified, against the wishes of the remaining spouse, and continuous for at least 12 months. Because the 12-month separation ground is already available and substantially easier to prove, desertion is rarely pursued in Maryland today.

5. Cruelty and Excessively Vicious Conduct (Fault)

These two grounds apply when one spouse has engaged in cruel or vicious conduct toward the other spouse or toward a minor child of the party seeking the divorce.

Cruelty generally refers to a course of harmful conduct that endangers the safety or health of the complaining spouse. Physical violence is not the only form that courts may recognize — persistent emotional abuse may qualify in some circumstances, though courts set a meaningful threshold.

Excessively vicious conduct focuses on specific acts so severe that continued cohabitation is dangerous and unreasonable. A single serious act of violence may be enough if it meets that threshold.

What you need to prove: These are fact-intensive grounds. Courts look for documented evidence such as medical records, police reports, photographs, and witness testimony. A single spouse’s account standing alone is generally not sufficient. If you or your children are in immediate danger, a protective order may be the most urgent priority — separate from and independent of the divorce filing itself.

6. Conviction of a Crime (Fault)

A spouse who has been convicted of a felony or misdemeanor and sentenced to serve at least three years in a penal institution may be divorced on this ground, provided the filing spouse files after the conviction has occurred.

What you need to prove: Court records establishing the conviction and the sentence are typically sufficient. This ground is seldom litigated today because the 12-month separation ground is simpler and produces the same end result.

7. Insanity (Fault)

Maryland allows absolute divorce on the ground that one spouse has been permanently and incurably insane and has been confined to a mental institution for at least three years before the divorce is filed.

What you need to prove: The court requires testimony from at least two licensed psychiatrists confirming the permanent and incurable nature of the incapacity. This is an exceptionally high standard, and the ground is very rarely used in practice.
