And boy, Bob, don't you and I both know how true that is in one of YOUR counties, huh? 

 This is where being a local abstractor really pays off:  you know your county.  One of Bob's counties was NOTORIOUSLY bad -- so much so that at one time I had to put out a blanket statement to all the clients who sent work to us in that area.  They seem to have improved lately.

Also, being a local, you know where you can ask for index corrections and where you shouldn't even bother.   Hillsdale and Lenawee - what I consider my "home" counties -- ALWAYS make corrections when I bring up an error (maybe 3 each in over 10 years of working those counties) and there is gratitude on both our parts!  

Finally, I would always include a disclaimer to the effect (affect?):  The results of this search are dependent upon the accuracy of the indices generated and maintained by others.  This search does not cover matters of record if same were not properly indexed.
