Inheritance tax; appraisal; appointment of appraisers

In order to fix the value of property subject to the payment of the inheritance tax, the county judge may appoint a clerk magistrate or some other competent person, or the clerk magistrate may appoint a competent person, as appraiser as often as or whenever occasion may require, except that when real estate is to be appraised by a competent person other than a county judge or a clerk magistrate, the county judge or clerk magistrate shall appoint a credentialed real property appraiser, but if the county judge or clerk magistrate finds that no credentialed real property appraiser is a disinterested freeholder of the county, some other competent person may be appointed.
