Appraisal Clause Example:

If “you” and ”we” fail to agree on the amount of loss, either may demand an appraisal of the loss. In this event, each party will choose a competent and impartial appraiser within 20 days after receiving a written request from the other. The two appraisers will choose a competent and impartial umpire. If they cannot agree upon an umpire within 15 days, “you” or “we” may request that the choice be made by a judge of a court of record in the state where the "residence premises" is located. The appraisers will separately set the amount of loss. If the appraisers submit an agreement to us, the amount agreed upon will be the amount of loss. 
If they fail to agree, they will submit their differences to the umpire. A decision agreed to by any two will set the amount of loss.   
                                                                               
Each party will: 
a. pay its own appraiser, and;
b. Bear the other expenses of the appraisal and umpire equally."
