A certified check is a personal check that your bank has verified and guaranteed, confirming that the funds are available in your account and setting them aside to cover the payment. Unlike a regular personal check, which can bounce if your account lacks sufficient funds, a certified check gives the recipient confidence that the payment will clear. Banks typically charge a small fee to certify a check, and the process requires you to visit a branch in person. Certified checks are often requested for large transactions like real estate purchases, car sales, or security deposits where the payee wants assurance of payment. While less common today, they remain a reliable alternative when electronic transfers aren't an option.
