Are you one of the thousands of Maryland residents living with a long-term partner and assuming you are legally married without a license? Does Maryland have common law marriage is a question that affects countless cohabiting couples across Baltimore, Rockville, Annapolis, and beyond. The direct answer is no.
Maryland does not recognize common law marriage formed within the state. Regardless of how many years you have lived together or how you present yourselves to family and friends, Maryland law requires a valid marriage license and a formal ceremony to establish a legally recognized marriage.
What Is Common Law Marriage?
Common law marriage is a legal relationship in which two people are considered married without obtaining a marriage license or holding a ceremony. In states that recognize it, couples must generally live together, agree to be married, and hold themselves out publicly as spouses.
Maryland has never adopted this doctrine. Under Md. Code, Family Law section 2-401, every person intending to marry in Maryland must obtain a marriage license from the clerk of the circuit court in the county where the marriage takes place.
Does Maryland Recognize Common Law Marriage From Other States?
Yes, with an important distinction. While common law marriage cannot be created in Maryland, the state does give full legal recognition to a valid common law marriage formed in another state.
This matters significantly for Maryland residents who previously lived in states like Colorado, Texas, Iowa, or Washington, D.C., all of which recognize common law marriage. If you formed a valid common law marriage there and later moved to Maryland, your marriage is recognized here.
Maryland courts can grant divorces and settle property rights for these couples. The Washington D.C. Factor. This is especially relevant for residents of Montgomery County, Prince George’s County, and other areas bordering the nation’s capital.
Washington, D.C., recognizes common law marriage. Maryland residents who worked and lived in D.C. before relocating may have unknowingly established a valid common law marriage that Maryland will uphold.
Legal Options for Unmarried Couples in Maryland
Since living together without marriage, Maryland legal rights offer limited automatic protections; cohabiting couples should consider the following options.
Registered Domestic Partnership
Maryland’s domestic partnership rights expanded significantly with legislation effective October 2023. A surviving registered domestic partner now holds inheritance rights equivalent to a spouse under intestacy law.
To register, both partners must file a Declaration of Domestic Partnership with the Register of Wills in their county of residence. The declaration must be notarized and signed by both parties.
Cohabitation Agreement
A cohabitation agreement that Maryland couples sign is a legally binding written contract that governs property ownership, financial responsibilities, and asset division if the relationship ends. Maryland courts enforce these written agreements.
This is the closest protection available to unmarried couples in the state and is strongly recommended by Maryland family law attorneys.
Unmarried Couple Property Rights in Maryland
Unmarried couple property rights in Maryland are determined largely by how assets are titled. Without a formal agreement or registered domestic partnership, Maryland views both partners as legal strangers for most property and inheritance purposes.
A surviving unmarried partner has no automatic right to inherit property unless named in a will or registered as a domestic partner.
Should You Consult a Maryland Family Law Attorney?
If you are in a long-term relationship without a formal marriage, speaking with a Maryland family law attorney is strongly advised. An attorney can help you draft a cohabitation agreement, register a domestic partnership, and structure estate planning documents such as wills, trusts, and powers of attorney to protect both partners.
