Delaware Annulment and Prohibited Marriage Laws

State laws regulate the institution of marriage, which includes annulment and certain restrictions on who may get married. Annulment is the legal process of invalidating a marriage, a different process than divorce, which may be sought in Delaware if there's a previously undissolved marriage or for other reasons. Delaware law also bans bigamy and marriage between double first cousins.

Annulment Basics

An annulment is conceptually different from a divorce. An annulment, rather than dissolving a marriage that is broken, requires a determination by the judge that the union was never valid in the first place. The difference is subtle, but significant. The "grounds for divorce" establish that a marriage is broken, while the "grounds for annulment" explain why the marriage wasn't legal to begin with. Prohibited Marriages

Delaware doesn't allow people to marry who are currently married, and also prohibits marriage between family members. Double first cousins may not marry. Double first cousins are so called because the siblings of one family marry the siblings of another family, e.g. two brothers marry two sisters. Also those who are more closely related than first cousins may not marry.
