Betterment Clause — a provision, often found in the physical damage section of automobile insurance
policies, which stipulates that if the repair or replacement of the damaged
parts results in better than "like kind or quality," the insurers
will not pay for this net improvement. This clause is designed to preserve the
concept of indemnity so the insured does not profit from the loss when the
circumstances are such that it is impossible for the insurer to repair or
replace the property without bettering the insured's position.
