When completing your application for health insurance, you will be asked to list the primary applicant. This refers to the head of the family in whose name the policy will be issued. This may be the husband or the wife, or either registered name of a domestic partnership if recognized in your state. For employer-sponsored group health plans, the primary applicant will be the employee of the company. If you are applying for coverage for just yourself, you will list your name as the primary applicant. If you are applying for coverage for just a child, then you will list the child as the primary applicant, even if they are not old enough to sign the application. A primary applicant must always be a person that will be included on the health plan. In most cases, if the primary applicant is of legal age, then that person must also sign the application for insurance. If a child is the primary applicant, a parent or legal guardian must sign the application on their behalf.
