Print today’s date including the month, day, and year.
Be very careful about post-dating checks (putting a future date on the check). Once you sign a check, it is legal tender and can be cashed regardless of the date you put on the check. So, if you don’t have the funds in your bank account, don’t rely on post-dating the check because that isn’t a guarantee that the check won’t be cashed earlier than the date of the check.
Pay to the Order Of
Print the person’s full name (first and last) or company name in which you are paying.
Print the numerical value of the amount of the check next to the dollar sign.
For example, if you are writing a check for $942.52 you will write “942.52” in the box.
Print the value of the check in word form on the line before "Dollars"
For example, if you are writing a check for $942.52 you will write “Nine Hundred and Forty Two dollars and 52/100” on the line.
Edited to add: Thank you to our friend Kristian who noted that you don't even need to add the "dollars" here – as "dollars" is already on the check! So, you can simply say "Nine Hundred and Forty Two and 52/100."
Always write the “change” out as (cents)/100
This can be left blank but can also be used to note what the payment is for, what account it is linked to, or a note to the receiver. Whenever you are paying bills with a check, reference the account number or invoice number here for your records.
Bottom Right Line/Signature Line
Sign the check! This makes it legal tender.
USE PEN. Never write a check with a pencil.
Be careful when writing checks – your personal information (name and address) as well as your banking information (routing number and bank account number) are all visible on your check. Don’t write a check to just anyone.
