Hi all.
Wonder if you can provide some advice.
After 25 years of zero offence driving, yesterday I received a NIP for speeding.

The letter is dated July 29th about an offence on July 1st (28 days after the alleged offence).
I received the letter on July 31st. I no longer have the vehicle.

As the serve date is more than 14 days after the offence date, is it now invalid?
If so, what would be the next step?
Many thanks!
