A legal curiosity

[blindswelledrat]

Not a big deal, just purely curious.
A chap came into my office today with a cheque that we had sent him 18 months ago, which the bank would not bank now and asked us to reissue it.
We are doing,obviously, but I was just curious as to whether we were legally obliged to.
No biggie, just interested

Thanks

Of infinite duration?
I assume so but somehow it equally feels like there should be a limit.
THen again, it probably doesn't. You (I) should know it's never been cashed hence should never assume you don't have to pay
