There are mainly two reasons of divorce in Alaska that the courts recognize for filing. These are classified as fault and no-fault divorce. In order to file for divorce in Alaska, the proper grounds must be established. Both spouses are involved in establishing these grounds, and both must substantiate and agree upon these, unless the divorcing spouse is trying to prove otherwise to the court. Under a no-fault divorce the grounds common stated are incompatibility of temperament which has caused the irremediable breakdown of the marriage. Under a fault divorce there are several grounds on which a person may file. Included in this list are: Adultery, failure to consummate the marriage at the time of the marriage and continuing to the commencement of the divorce, desertion up to a one year period, adultery, conviction of a felony, cruel and inhuman treatment, incurable mental illness, and addiction to drugs or the continuing gross drunkenness.
