Adultery no longer serves as a ground for divorce in Maryland following the 2023 no-fault divorce reform, but infidelity still significantly impacts alimony awards, property division, and dissipation claims. Under Maryland Family Law § 11-106, courts consider the circumstances that contributed to the estrangement of the parties as 1 of 12 statutory factors when determining spousal support amounts and duration. If your cheating spouse spent marital funds on an affair, Maryland courts may compensate you through a larger monetary award under Maryland Family Law § 8-205, as established in the landmark 2025 case Sims v. Sims.

How Maryland Eliminated Fault-Based Divorce Grounds
Maryland became a pure no-fault divorce state on October 1, 2023, when Senate Bill 36 eliminated all fault-based grounds including adultery, desertion, cruelty, and insanity. Under Maryland Family Law § 7-103, Maryland now recognizes only three grounds for absolute divorce: mutual consent, irreconcilable differences, and six-month separation. The October 2025 amendments further reduced the separation period from 12 months to 6 months and allowed spouses to live under the same roof while pursuing separate lives and still qualify for divorce. This fundamental shift means you cannot file for divorce based on your spouse's adultery in Maryland. However, the legislature deliberately preserved the court's ability to consider fault when making financial determinations, recognizing that marital misconduct often has economic consequences that deserve judicial attention.
The elimination of fault-based divorce grounds streamlined the divorce process significantly. Prior to 2023, proving adultery required corroborating evidence beyond the testimony of the accusing spouse, creating lengthy and expensive litigation. Today, a couple seeking divorce through mutual consent can complete the process in 1-3 months with no mandatory waiting period. The filing fee remains $165 statewide across all Maryland Circuit Courts as of March 2026. If you cannot afford court filing fees, Maryland law allows you to request a fee waiver if your household income falls at or below 125% of the federal poverty guidelines.
Adultery and Alimony in Maryland: The 12-Factor Analysis
Maryland courts consider adultery when determining alimony awards under the circumstances that contributed to the estrangement factor in Maryland Family Law § 11-106(b). The statute requires judges to weigh 12 specific factors when deciding whether to award alimony, how much to award, and for how long. Unlike neighboring states such as New York, which uses a statutory formula for temporary maintenance, Maryland gives judges broad discretion to balance these factors case by case. Adultery qualifies as a circumstance contributing to the breakdown of the marriage, meaning an affair can directly influence the financial outcome of your divorce through increased or decreased spousal support.
The 12 statutory alimony factors under Maryland Family Law § 11-106(b) include: (1) the ability of the party seeking alimony to be wholly or partly self-supporting; (2) the time necessary to gain education or training for suitable employment; (3) the standard of living established during the marriage; (4) the duration of the marriage; (5) the contributions, monetary and nonmonetary, of each party to the well-being of the family; (6) the circumstances that contributed to the estrangement of the parties; (7) the age of each party; (8) the physical and mental condition of each party; (9) the ability of the paying spouse to meet both parties' needs while meeting their own; (10) any agreement between the parties; (11) the financial needs and resources of each party; and (12) whether the award would cause a spouse receiving government benefits to become ineligible.
Maryland recognizes three types of alimony: pendente lite (temporary support during litigation), rehabilitative (time-limited support while a spouse gains education or employment skills), and indefinite alimony. Under Maryland Family Law § 11-106(c), courts may award indefinite alimony if the receiving spouse cannot reasonably be expected to make substantial progress toward self-support due to age, illness, or disability, or if the respective standards of living would be unconscionably disparate even after rehabilitation. Adultery does not automatically bar a spouse from receiving alimony, but when combined with other factors such as a long marriage or significant income disparity, a judge may increase or decrease support based on which spouse committed the affair.
Adultery and Property Division: Dissipation Claims
Adultery most significantly affects property division in Maryland through dissipation of marital assets claims. Under Maryland Family Law § 8-205, Maryland follows the equitable distribution model, meaning courts divide marital property fairly based on 11 statutory factors rather than automatically splitting assets 50/50. When a spouse uses marital funds to finance an extramarital affair through gifts, trips, hotel rooms, or financial support for a paramour, the innocent spouse can claim dissipation and seek compensation through a larger monetary award. The Maryland Court of Appeals defined dissipation in Omayaka v. Omayaka (417 Md. 643, 2011) as spending that depletes marital funds with the principal purpose of reducing what would be available for equitable distribution.
The 2025 Sims v. Sims decision from the Appellate Court of Maryland established critical precedent for affair-related dissipation claims. In that case, the wife alleged her husband dissipated $547,254.13 through affair-related spending ($281,243.17), excessive travel ($81,306.30), dining ($125,468.16), cash withdrawals ($93,613), and liquor purchases ($13,028.17). The Appellate Court emphasized that the burden of proving dissipation lies with the accusing spouse, who must identify specific transactions and demonstrate the funds served a non-marital purpose. Once that threshold is met, the burden shifts to the spending spouse to justify the expenditures. The court noted that treating dissipated assets as extant marital property prevents the wrongdoing spouse from escaping consequences and protects the innocent spouse's rightful share.
Maryland courts use a three-step process for property division: (1) classify property as marital or nonmarital; (2) value all marital assets; and (3) determine the monetary award based on the 11 statutory factors. The circumstances that contributed to the estrangement appears as factor 4 under Maryland Family Law § 8-205(b). While adultery alone does not forfeit a cheating spouse's property interest, courts may adjust the monetary award to compensate for proven dissipation. In practice, many Maryland divorces result in approximately equal divisions, but courts may award 60/40, 70/30, or other proportions when circumstances like proven affair spending warrant an unequal distribution.
Adultery and Child Custody: The Best Interest Standard
Adultery rarely affects child custody determinations in Maryland because courts focus exclusively on the best interest of the child standard rather than parental misconduct. Under Maryland Family Law § 5-203(d), neither parent holds a presumptive right to custody superior to the other parent. The landmark 1977 Davis v. Davis decision established that while adultery may be a relevant consideration in custody awards, no presumption of unfitness arises from it. Courts weigh adultery only insofar as it affects the child's welfare, alongside all other pertinent factors.
The 1979 Swain v. Swain (43 Md.App. 622) decision clarified that adultery does not become a custody factor if the child has not been exposed to it. This principle applies broadly to parental behavior: in Burak v. Burak, the Appellate Court held that parental lying at trial, drug use, and sexual behavior including polyamory do not evidence parental unfitness unless shown to be detrimental to the child or unless the child is aware of the conduct. Maryland Rule 9-204.1, effective 2020, sets out 14 factors judges may consider in custody matters, focusing on the child's relationships, adjustment to home and school, and each parent's fitness and ability to maintain the child's relationship with the other parent.
If your spouse's affair involved exposing children to inappropriate situations, introducing children to the paramour in a confusing manner, or neglecting parental duties to pursue the relationship, these specific facts could influence custody. However, the affair itself without child exposure typically has no bearing on custody outcomes. Maryland courts have consistently upheld that a parent's adulterous misconduct does not diminish their caring capacity in the eyes of the court when the children remain unaware and unaffected.
Maryland Residency Requirements for Divorce Filing
To file for divorce in Maryland, at least one spouse must be a Maryland resident. Under Maryland Family Law § 7-101, if the grounds for divorce occurred outside Maryland, at least one spouse must have resided in Maryland for a minimum of six months before filing the complaint. If the grounds occurred within Maryland, there is no stated residency waiting period, though you must still file in a Maryland Circuit Court. Maryland's residency requirement applies to the state as a whole, not any particular county, meaning as long as one spouse has established residence anywhere in Maryland, the divorce can be filed.
For venue purposes, the complaint must be filed in the Circuit Court of the county where either the plaintiff or defendant resides, or where either party is regularly employed or maintains a place of business. You can prove residency through your driver's license, voter registration, tax filings, utility bills, and bank statements showing a Maryland address. Military members may file for divorce in Maryland if they established residence in the state prior to entering the armed services, even if they have not lived in Maryland since. If you or your spouse move to another state after filing, you may still have your case heard in Maryland as long as one spouse was a Maryland resident when the complaint was filed.
Filing for Adultery-Related Divorce in Maryland
While you cannot file for divorce on adultery grounds, you can incorporate your spouse's infidelity into your divorce case through proper pleading of alimony and property claims. To file for divorce in Maryland, submit Form CC-DR-020 (Complaint for Absolute Divorce) to your county's Circuit Court along with the $165 filing fee. Your spouse has 30 days to respond after service of process. For mutual consent divorces where both spouses agree on all terms including property, support, and custody, the process typically completes in 1-3 months with no mandatory waiting period.
If filing based on irreconcilable differences or six-month separation, be prepared for a longer timeline. Contested divorces involving disputes over alimony, property division, or custody can take 12-18 months or longer depending on case complexity and court dockets. When adultery and dissipation are at issue, gather documentation of affair-related spending including bank statements, credit card records, receipts for gifts or trips, and communications evidencing the expenditures. Maryland courts require specific evidence linking marital fund expenditures to the extramarital relationship before shifting the burden to your spouse to justify the spending.
Is Adultery Still a Crime in Maryland?
Technically, adultery remains a misdemeanor under Maryland Criminal Law § 10-501. However, prosecutions are extraordinarily rare and the statute is widely considered unenforceable. The criminal classification has no practical effect on divorce proceedings, though some attorneys note its continued existence on the books. The criminal penalty, a $10 fine, reflects the statute's antiquated nature. No recent Maryland appellate decisions address criminal adultery prosecution, and law enforcement agencies do not prioritize or pursue these cases.
Working with a Maryland Divorce Attorney on Infidelity Cases
Consulting with an experienced Maryland divorce attorney is particularly important when adultery affects your case through potential alimony adjustments or dissipation claims. An attorney can help you document and quantify affair-related spending, properly plead dissipation in your complaint or answer, and present evidence effectively at trial. Maryland attorneys typically charge $250-$450 per hour for divorce representation, with complex cases involving dissipation claims often requiring 30-60 hours of legal work depending on the assets involved and extent of documentary evidence.
When selecting an attorney, ask about their specific experience with dissipation cases and alimony litigation involving marital misconduct. Request information about their typical case timelines and approach to settlement negotiations versus trial preparation. Many Maryland family law attorneys offer initial consultations for $150-$300, during which you can discuss the specific facts of your infidelity situation and receive preliminary guidance on likely outcomes.
Frequently Asked Questions
Can I file for divorce based on my spouse's adultery in Maryland?
No. Maryland eliminated adultery as a divorce ground on October 1, 2023. Under Maryland Family Law § 7-103, you can only file for divorce based on mutual consent, irreconcilable differences, or six-month separation. However, adultery remains relevant to alimony and property division as one of the statutory factors courts must consider when making financial awards.
Will my cheating spouse have to pay me more alimony because of the affair?
Possibly. Under Maryland Family Law § 11-106(b), courts consider the circumstances that contributed to the estrangement as 1 of 12 alimony factors. A judge may increase alimony to the innocent spouse, but must weigh all 12 factors including income disparity, marriage duration, and each party's needs. The affair alone does not guarantee higher support.
Can I recover money my spouse spent on their affair?
Yes, through a dissipation claim under Maryland Family Law § 8-205. If your spouse used marital funds for gifts, trips, or support for a paramour, courts may compensate you through a larger share of remaining marital property. The 2025 Sims v. Sims case clarified that you must identify specific transactions and prove they served a non-marital purpose to shift the burden to your spouse.
Will adultery affect child custody in my Maryland divorce?
Rarely. Under the Davis v. Davis (1977) standard, adultery creates no presumption of parental unfitness. The Swain v. Swain (1979) decision established that adultery only affects custody if the child was exposed to it. Courts focus on the child's best interest, evaluating each parent's ability to provide care regardless of marital misconduct.
How long does a divorce take in Maryland when adultery is involved?
Uncontested divorces with adultery-related financial issues can complete in 3-6 months. Contested cases with dissipation claims typically take 12-18 months due to the need for financial discovery, expert testimony on asset tracing, and potential trial. The $165 filing fee applies regardless of case complexity.
Does Maryland have a waiting period before divorce?
Maryland requires no waiting period for mutual consent divorces where both spouses agree on all terms. For separation-based divorces, you must live apart for 6 months (reduced from 12 months in October 2025). You may live under the same roof while pursuing separate lives and still qualify for separation-based divorce.
Can I prove adultery affected my spouse's ability to parent?
Only if the affair directly impacted your children. Maryland courts require evidence that children were exposed to inappropriate situations, that parental duties were neglected during the affair, or that the relationship harmed the children's emotional wellbeing. The affair itself, without proven child impact, typically has no custody effect.
What evidence do I need for a dissipation claim in Maryland?
You must document specific transactions using bank statements, credit card records, receipts, and communications showing your spouse spent marital funds on the affair. Under Sims v. Sims (2025), once you establish a prima facie case of affair-related spending, your spouse must justify each expenditure or face an adverse property adjustment.
Is adultery still illegal in Maryland?
Technically, adultery remains a misdemeanor under Maryland Criminal Law § 10-501 with a $10 fine. However, prosecutions are virtually nonexistent, and the statute has no practical effect on divorce proceedings. The criminal status does not enhance your position in alimony or property division negotiations.
Should I hire a private investigator to prove my spouse's affair?
Generally unnecessary since adultery is no longer a divorce ground. However, if your spouse denies spending marital funds on the affair and you need evidence for a dissipation claim, a forensic accountant may be more valuable than a private investigator. Discuss documentation strategies with your divorce attorney before incurring investigation costs.
