Common law marriage in Maryland cannot be created within the state. No matter how long you live together, combine finances, or introduce one another as spouses, Maryland will not treat you as married unless you obtain a marriage license and have a ceremony performed by an authorized official.1Maryland General Assembly. Maryland Code Family Law 2-401 There is one important exception: if you formed a valid common law marriage in a state that allows them and later moved here, Maryland will recognize that marriage as legally binding.2The Maryland People’s Law Library. Common Law Marriage
What Maryland Requires for a Legal Marriage
Two things are mandatory. You need a marriage license from the clerk of the circuit court in the county where the ceremony will take place.1Maryland General Assembly. Maryland Code Family Law 2-401 And a ceremony must be performed by someone the state authorizes: a judge, a court clerk or deputy clerk, or an official of a religious organization acting under that group’s rules.3Maryland General Assembly. Maryland Code Family Law 2-406
Skip either step and you are not married under Maryland law. That means no marital property rights, no automatic inheritance, no spousal privilege in court, and no obligation to go through divorce if you separate. A couple who has lived together in Maryland for thirty years without a license and ceremony remains, legally, two single people.
When Maryland Recognizes a Common Law Marriage From Another State
If you entered a valid common law marriage in a state that permits them and then relocated to Maryland, your marriage carries over with full legal force, exactly as if you had been licensed and married here.2The Maryland People’s Law Library. Common Law Marriage You are entitled to property division, spousal support, inheritance rights, and every other benefit of legal marriage.
The other side of recognition matters just as much. If the relationship ends, you need a formal divorce through Maryland’s courts, just like any other married couple. Maryland courts handle the divorce and determine the rights of common law spouses living in the state.2The Maryland People’s Law Library. Common Law Marriage You cannot simply walk away.
States Where You Could Have Formed One
Only a small number of jurisdictions still permit new common law marriages. The list currently includes Colorado, Iowa, Kansas, Montana, South Carolina, Texas, Utah, Rhode Island, the District of Columbia, and, through case law, Oklahoma. New Hampshire recognizes a limited version that applies only for inheritance purposes after one partner dies.
Each state writes its own rules, but the common elements run together: both partners must agree to be married right now, not at some future date, they must live together, and they must publicly represent themselves as a married couple. Several states require both partners to be at least 18. The trend has been to phase common law marriage out. States including Alabama, Georgia, Ohio, and Pennsylvania abolished it in recent decades, though marriages formed before each state’s cutoff date remain valid.
Proving the Marriage If It’s Questioned
There is no marriage certificate for a common law marriage, so Maryland courts can require you to prove the marriage exists. This issue usually surfaces during a divorce or when one spouse dies and the survivor seeks an inheritance or Social Security benefits.2The Maryland People’s Law Library. Common Law Marriage
Courts look at the whole picture to decide whether both partners genuinely agreed to be married and held themselves out publicly as a couple while living in a state that allows common law marriage. Evidence that tends to carry weight includes joint tax returns filed as married, shared bank accounts or property titles, insurance policies naming each other as a spouse, testimony from people who understood you to be married, use of the same last name, and written declarations of the marriage.
The strength of a case depends heavily on the law of the state where the marriage was formed, because each jurisdiction sets its own elements. If your common law marriage is being challenged in a divorce or estate dispute, you want an attorney familiar with both Maryland law and the originating state’s requirements.
Registered Domestic Partnership as a Maryland Option
Many unmarried couples in Maryland do not know this option exists. The state allows two people to register a domestic partnership by filing a Declaration of Domestic Partnership with the Register of Wills in the county where they live. The filing fee is capped at $25.
To qualify, both partners must be at least 18, not currently married or in another domestic partnership, and in a committed relationship of mutual support. The declaration must be signed before a notary and include each partner’s full legal name, address, date of birth, and Social Security number.
The inheritance protections are the main draw. A surviving registered domestic partner receives the same share of a deceased partner’s estate as a surviving spouse would under Maryland’s intestacy law. When there are no minor children, that is the entire estate. When minor children survive, the partner receives half.4Maryland General Assembly. Maryland Code Estates and Trusts 3-102 Registered partners also get priority appointment as personal representative of the estate and an exemption from Maryland’s inheritance tax on the couple’s primary residence when it is held as joint tenants.5The Maryland People’s Law Library. Unmarried Cohabitants’ Benefits
A domestic partnership is not a substitute for marriage. It does not give you joint tax filing status, FMLA leave rights, Social Security spousal benefits, or the property division protections that come with divorce. But for inheritance, it is powerful and costs almost nothing to set up.
Protecting Yourself as an Unmarried Couple
Without legal marriage or at least a domestic partnership, your partner has no automatic right to inherit from you, make medical decisions on your behalf, or manage your finances if something happens to you. A few documents close those gaps.
A cohabitation agreement is a written contract between unmarried partners addressing property ownership, shared expenses, support obligations, and what happens to assets if the relationship ends. Maryland courts enforce them. Oral agreements about personal property are technically enforceable, but proving the terms is difficult, so put it in writing.6The Maryland People’s Law Library. Unmarried Cohabitants’ Right to Support and Property
A will matters even more for unmarried couples. Without one, Maryland’s intestacy laws send your assets to blood relatives. An unmarried partner receives nothing unless you have registered a domestic partnership or named them in a will.5The Maryland People’s Law Library. Unmarried Cohabitants’ Benefits
An advance directive lets you name a health care agent who can make medical decisions if you cannot communicate. Without one, hospitals look to next of kin, and an unmarried partner may have no legal standing in your care.7Maryland Department of Health. Maryland Advance Directive Program A durable power of attorney for finances does the same job for money matters, authorizing your partner to manage bank accounts and pay bills if you become incapacitated. Without it, your partner would have to petition a court for that authority.
How you title shared property is equally important. Maryland doesn’t give unmarried partners any version of the property division process that divorcing spouses go through. Ownership follows the title. If you buy a home together, you hold it as either joint tenants or tenants in common. Joint tenancy includes a right of survivorship, so the surviving partner automatically becomes sole owner. Tenancy in common does not; the deceased partner’s share passes through their will or, if there is none, to their legal heirs.6The Maryland People’s Law Library. Unmarried Cohabitants’ Right to Support and Property
The detail that catches couples off guard: Maryland law presumes tenancy in common unless the deed explicitly creates a joint tenancy.6The Maryland People’s Law Library. Unmarried Cohabitants’ Right to Support and Property If your deed does not specifically say “joint tenants” or “joint tenants with right of survivorship,” you are tenants in common, and your partner could end up co-owning the home with your parents or siblings. When you buy property together outside of marriage, the deed language is not optional.
Paternity for Unmarried Parents
When married parents have a child in Maryland, the law presumes the husband is the father. That presumption does not exist for unmarried couples, so an extra step is needed to establish legal fatherhood.
The simplest route is an Affidavit of Parentage, a voluntary form both parents sign. Hospital staff can help complete it at birth at no cost. If it is not signed at the hospital, both parents can sign it later before a notary and mail it to the Division of Vital Records. The affidavit can be signed any time before the child turns 18.8The Maryland People’s Law Library. Paternity
Signing is a serious legal act. A parent who changes their mind has only 60 days to rescind it. After that, undoing it requires a court order and proof of fraud, duress, or a genuine factual mistake.8The Maryland People’s Law Library. Paternity If the father will not voluntarily acknowledge parentage, the other parent can petition the court for an order, which is often the step that unlocks child support, custody rights, and access to benefits such as the father’s health insurance.
