The court hearing is obviously more expensive than just asking the assessor's office to make a fix, but it's an option.

What was the court cost relative to the assessment in question?
P.S. Assessors are counting on owners not questioning their appraisals each year, we review
them annually, and challenge whenever we know they're wrong. The result? For the cost
of a few emails and a couple stamps, we've saved many thousands over twelve years.
