In Oregon, marriage between first cousins or anyone more closely related, whether by blood or adoption, is explicitly prohibited. There are no exceptions to this rule, and such a marriage will not be legally recognized by the state. If you attempt to marry your first cousin, the marriage will be considered void under Oregon law.
Who Can You Marry in Oregon?
Second cousins and more distant relatives are allowed to marry in Oregon. First cousins once removed, meaning the child of your cousin or your parent’s cousin, are also permitted to marry in Oregon. Marriages between first cousins by adoption may be legal, but only if the relationship is based on adoption and not blood.
