Id. Because respondent has a duty of support "imposable by law," we remand the case to Hennepin County District Court for review of the merits of the RURESA petition. If the petition is granted, the district court should then determine the amount of reimbursement in accordance with Minn.Stat. § 518.551, subd. 5; see Minn.Stat. § 518C.17, subd. 1; State ex rel. County of Carlton v. Greenwood, 398 N.W.2d 636, 638 (Minn.App. 1987) (once court determines obligor owes duty of support, it may independently determine appropriate level of support to impose on obligor). If reimbursement is granted, the trial court may consider respondent's increased visitation expenses in determining an appropriate level of reimbursement.
