Art. 47.08. WRITTEN INSTRUMENT.  If the property is a written instrument, it shall be deposited with the county clerk of the county where the proceedings are had, subject to the claim of any person who may establish his right thereto.  The claimant of any such written instrument shall file his written sworn claim thereto with the county judge.  If such judge be satisfied that such claimant is the real owner of the written instrument, the same shall be delivered to him.  The county judge may, in his discretion, require a bond of such claimant, as in other cases of property claimed under any provision of this Chapter, and may also before such delivery require the written instrument to be recorded in the minutes of his court.
