A clearance letter is basically a background check. It is sometimes referred to as a letter of good conduct. It can be done at any Clay County Sheriff substation. The full name, date of birth, race, sex and social security number of the persons who needs the clearance must be provided. The charge is $5 (cash, money order or company check only). A letter will be provided stating either "no local record" or "record". If the subject has a local record, a printout of the arrest history will be attached.
