When an execution for the enforcement of a judgment obtained in a case not within the classes enumerated in section 40-103 is levied upon the lands or tenements of a claimant, the claimant may at any time prior to confirmation of sale apply to the district court in the county in which the homestead is situated for an order to determine whether or not such lands or tenements, or any part thereof, are exempt as a homestead and, if so, the value thereof.
