Here are the factors for alimony
If the parties are not in agreement, the court may order maintenance for a limited or indefinite period of time, in gross or in installments, as may be just and necessary without regard to which of the parties is in fault; an award of maintenance must fairly allocate the economic effect of dissolution of marriage by being based on a consideration of the following factors: (A) the length of the marriage and station in life of the parties during the marriage; (B) the age and health of the parties; (C) the earning capacity of the parties, including their educational backgrounds, training, employment skills, work experiences, length of absence from the job market, and custodial responsibilities for children during the marriage; (D) the financial condition of the parties, including the availability and cost of health insurance
; (E) the conduct of the parties, including whether there has been unreasonable depletion of marital assets; (F) the division of property
under (4) of this subsection; and (G) other factors the court determines to be relevant in each individual case. Alaska Dissolution Statutes- Sections: 25-24-165, 25.24.230
