Protect Yourself: Do Not Abbreviate 2020
When signing and dating legal documents do not use 20 as the year 2020. It leaves you vulnerable to someone coming along and altering the date.
March 9, 2020 being written as 3/9/20 could be modified to 3/9/2017 or 3/9/2018.
Don't risk legal or financial documents; don't abbreviate the year!
