No, Alaska does not have common law marriage. Under Alaska Statute 25.05.011, every marriage performed in the state requires both a marriage license and a solemnization ceremony to be legally valid.1Justia. Alaska Statutes 25.05.011 – Civil Contract Living together for years, sharing finances, using the same last name, or introducing each other as spouses will not create a marriage under Alaska law. The one narrow exception involves couples who formed a valid common law marriage in another state before moving here.
What Alaska Requires Instead
Alaska treats marriage as a civil contract with two steps that cannot be skipped. First, both parties obtain a marriage license. Second, the marriage is solemnized. The statute states plainly: “A marriage performed in this state is not valid without solemnization.”1Justia. Alaska Statutes 25.05.011 – Civil Contract Both parties must be at least 18, an active-duty member of the armed forces, or otherwise qualified under the state’s licensing provisions.
Solemnization itself is simple. The parties declare in front of each other, the officiant, and at least one competent adult witness that they take each other as spouses. The officiant and witness sign the certificate, which is filed with the local registrar within seven days. No religious element is required, no waiting period applies, and no specific script must be followed beyond confirming both parties are entering the marriage freely.
Because Alaska draws its line at the license and the ceremony, there is no length of cohabitation, no depth of financial entanglement, and no degree of public commitment that adds up to a marriage inside the state.
Common Law Marriages Formed in Another State
If you established a common law marriage in a state that recognizes them, Alaska will generally honor that marriage. The U.S. Constitution’s Full Faith and Credit Clause requires each state to give effect to the “public Acts, Records, and judicial Proceedings of every other State,”2Library of Congress. Article IV Section 1 and a marriage validly formed elsewhere is normally treated as valid after you move.
Only a small number of states currently permit new common law marriages: Colorado, Iowa, Kansas, Montana, South Carolina, Texas, and Utah allow them by statute under varying conditions, and Rhode Island and Oklahoma recognize them through case law. New Hampshire recognizes cohabiting couples as married only after one partner dies, and only if they lived together for at least three years. If you never lived in one of these places, the doctrine has no practical application to your situation.
The catch is proof. A common law marriage does not come with a certificate, so if the marriage’s existence is ever questioned, you may have to assemble the evidence yourself. Joint tax returns filed as married, shared bank accounts, property deeds, insurance policies naming each other as spouse, and testimony from people who knew you as a married couple all help. Whether you were actually married turns on the law of the state where the relationship was formed, not on Alaska’s stricter rules.
Social Security Benefits
The Social Security Administration will pay spousal or survivor benefits based on a common law marriage, but the SSA applies the law of the state where the couple lived when the worker filed or died. The marriage must have been “contracted in a State where common-law marriages are recognized,” and all of that state’s requirements must have been met.3Social Security Administration. Common-Law Marriage – General The SSA also requires that the underlying agreement contemplate “a permanent union exclusive of all others” ending only through death, divorce, or annulment.
Ending a Recognized Common Law Marriage
If Alaska recognizes your out-of-state common law marriage, ending it requires a divorce, the same as any other marriage. There is no walking away because you never had a ceremony. The same rules on property division, spousal support, and child custody apply.
What Happens if an Unmarried Partner Dies
This is where Alaska’s rule bites hardest. Alaska’s intestacy statute gives significant shares of an estate to a “surviving spouse,” and the whole estate when no children or parents survive.4Justia. Alaska Statutes 13.12.102 – Share of Spouse An unmarried partner is not a surviving spouse, and inherits nothing under the probate code no matter how long the relationship lasted.
The Alaska Supreme Court confirmed this in In re Estate of Hatten (2019), a case involving partners who had been together over 20 years. The court held that Alaska’s probate code “comprehensively governs” the rights of surviving spouses and domestic partners, and that a surviving domestic partner “inherits none of a deceased partner’s estate under the probate code.” The estate instead passes down the statutory hierarchy: children, then parents, then siblings, and outward from there. A partner of two decades receives nothing while a distant relative could inherit everything.
That outcome is preventable, but only through affirmative legal steps taken while both partners are alive and competent.
How to Protect Each Other Without Marriage
Because Alaska gives unmarried partners no automatic legal protections, the documents below do the work marriage would otherwise do. None of them is optional if you want your partner treated the way a spouse would be.
A Will
A will is the single most important document for an unmarried couple. Without one, your partner has no inheritance rights. A properly executed will lets you leave property, accounts, and other assets directly to your partner, bypassing the intestacy rules that would otherwise route everything to blood relatives.
Advance Health Care Directive
Without a health care directive, your partner has no automatic authority to make medical decisions for you if you cannot make them yourself. Alaska allows you to execute a durable power of attorney for health care naming your partner as your agent. The document must be written, signed, dated, and witnessed either by two adult witnesses who personally know you or by acknowledgment before a notary. If you use two witnesses, at least one must be unrelated to you by blood, marriage, or adoption, and neither witness can be the agent you are appointing.5Justia. Alaska Statutes 13.52.010 – Advance Health Care Directives
Financial Power of Attorney
A separate financial power of attorney lets your partner handle banking, pay bills, manage investments, and deal with other financial matters if you cannot. Alaska recognizes durable powers of attorney that remain effective after the principal becomes incapacitated. Anyone you trust can serve as your agent; the person does not need to be a spouse or relative.
Cohabitation Agreement
A cohabitation agreement sets out how you and your partner handle finances, own property, and divide assets if the relationship ends. Alaska courts apply ordinary contract principles to unmarried couples, so a written agreement about property and financial obligations can be enforceable. Without one, disputes over shared property come down to who holds title and whether the other partner can prove an implied understanding about sharing, which is a much harder fight to win.
Joint Tenancy and Beneficiary Designations
Real estate held as joint tenants with right of survivorship passes directly to the surviving partner outside of probate. Naming your partner as beneficiary on life insurance, retirement accounts, and payable-on-death bank accounts moves those assets the same way. These designations cost nothing to set up and override whatever the intestacy statute would otherwise dictate.
