Are your Utah repair authorizations and added-work approvals documented correctly?

Utah's Division of Consumer Protection states that a mechanic must obtain express authorization for repairs, inspections, or other services after discussing the anticipated work, estimated charges, and reasonably expected completion date. If the service will cost more than $50, the mechanic must provide the customer a copy or transcript of the authorization by the time the bill is received. Express authorization is also required for additional unforeseen but necessary work when its cost is 10% or more of the original estimate.
