When any county surveyor is interested in any survey to be made, the judge of the superior court or the judge of the probate court of the county in which the land is located, upon the application of any party in interest, shall appoint a competent, disinterested surveyor or, in his discretion, may appoint the surveyor of any adjoining county to make the survey. If the surveyor appointed is not a county surveyor, before entering on the survey, he shall subscribe before some judicial officer of the county the oath required of county surveyors. The rights, powers, and duties of the surveyor so appointed shall be the same as those of the county surveyor. The return of the surveyor shall have the same force and effect as do other surveys.
