Alaska doesn't grant an annulment per se, but rather will declare that a marriage was never valid. This is determined if it is established that the marriage was void or voidable based on the following grounds:

- If one of the parties was already married to another person.

- If the spouses are more closely related to each other than third cousins (either whole or half-blood)

- If either party was a minor and didn’t receive the consent of their parent or guardian. An annulment may not be filed if the parties willingly lived together as husband and wife after the minor party attained the age to legally consent to marriage.

- If either party was of a mentally impaired state at the time of marriage, unless the couple willingly lived as husband and wife after the impaired party comes to reason.

- If the marriage was entered into fraudulently, unless the individuals freely lived together as a married couple after the facts constituting the fraud are revealed.

- If one party was pressured to consent to the marriage, unless that spouse willingly lives with the other after the marriage.

- Failure to consummate the marital relationship at the time of the marriage. An annulment may not be granted if the couple later on has sexual relations during the marriage.
