A regular check is issued by the account holder on their own account, and therefore its payment depends on available funds and the check's validity at the time of presentation.
Steps
A bank check, on the other hand, is issued by the bank itself according to specific procedures and with sufficient funds, giving the beneficiary a higher degree of security in some large transactions.
Before using either type of check, inquire about fees, cancellation and collection procedures, and whether the other party requires a specific format.
The figures, fees and limits in this answer vary by bank and change over time — confirm them with your bank or the official source before acting.
