When signing and dating legal or important documents it is important to get this right.
Most people when writing or typing a date would use the format dd/mm/yy e.g. 06/03/20.
However for the year 2020 this is not recommended.
We would strongly advise to use the format dd/mm/yyyy e.g. 06/03/2020.
The reason for this is it would be far too easy for someone to retrospectively change the year if you used the format dd/mm/yy. So for example, if you wrote the date as 06/03/20 and someone want to change this date back to the 6th of March 2019 all they would need to do is add a 19 on to the end i.e. 06/03/20 would the read 06/03/2019!!!
