I just read a great legal tip worth sharing. Many people date documents in this way: Day/Month/Year. When you date a document this year, it would be prudent to use all four digits for the year. If you enter a date like 06/01/20, someone could easily modify this date to 06/01/2017 or any previous year from this millennium. So start the practice of using a 4-digit year today and protect yourself legally throughout 2020!
