Logan Aldridge has presented a check for $3,000 to Stephanie Brooks. The check is in payment for a
set of antique furniture Brooks sold to Aldridge.
Per Brooks's request, the check is certified by
Aldridge's bank, 1st Bank of the North American
Hemisphere.

Why would Brooks (or any other payee, for that
matter) request that the drawer present a
certified check, as opposed to a non-certified one?
What is the legal effect of a certified check?
