Alaska Stat. § 09.35.200
When property liable to an execution against several persons is sold and more than a due proportion of the judgment is satisfied out of the proceeds of the sale of the property of one of them or one of them pays more than a due proportion without a sale, that person may compel contributions from the others. When a judgment is against several and is upon an obligation of one of them as security for another and the surety pays the amount or a part of it, either by sale of the surety's property or before sale, the surety may compel repayment from the principal. In that case, the person so paying or contributing is entitled to the benefit of the judgment to enforce contribution or repayment if the person files notice of payment and claim to contribution or repayment with the court where the judgment was rendered within 30 days after the payment.
