Found an old un-cashed paycheck. How long is it good for? What to do if it's expired?
In the UK the official rule is that a cheque is valid for 3 years from the date it was wrote. However after 3 months some banks can choose to turn them down. I had a cheque once that was a year old which is when I looked it up to see whether it was stil valid, and I found the laws regarding it then.  I was actually quite surprised it was 3 years! Btw if it does bounce your quite entitled to ask your employer for a replacement cheque.  They owe it you and it's just sat in their account assigned to you anyway.
