Several states do recognize common-law marriage. You will need to review your state’s laws to see if common-law marriage is recognized in your state. Even if a state does not recognize common-law marriage, an employer may choose to recognize this family unit if that decision is compatible with the guidelines of the health insurance carrier. Typically, employers will only recognize common-law if their state does. If you are recognizing common-law marriage and acknowledging it for your healthcare, there are certain requirements an employee should demonstrate to “prove” the established partnership. These requirements could also vary by health insurance carrier and may include signing an Affidavit attesting they meet the requirements. Most health insurance carriers have these forms available. Contact your carrier for details regarding your plan requirements.
