Ohio Revised Code Title III. Counties § 315.34

Within his own county, a county engineer may call before him, examine on oath, and take in writing the testimony of any witnesses for the establishment of any surveyed or agreed corner of the lands of any person who applies to him, after notice has been given to the person holding adjoining lands, as required in taking testimony for the establishment of old or decayed corners of land by section 315.30 of the Revised Code.  The taking of testimony under this section shall be under the same regulations and restrictions and in the same manner as provided by sections 315.28 to 315.33, inclusive, of the Revised Code.

Testimony taken under this section shall have the same effect in law as evidence taken to perpetuate old or decayed corners under such sections.  The engineer, other officers, and witnesses are entitled to demand and receive from the persons interested in the surveys and establishment of corners, under this section, the same fees as are allowed by section 315.33 of the Revised Code for similar services.
