stopping payment on a check--how long does it take?
user
is this a usa bank to a usa bank transaction?  if so, it will clear in one to two business days.  once cleared, the landlord cannot stop pay it.  he can, however, dishonestly claim it was a fraudulent check and attempt a chargeback. if you want absolute certainty the money will not be recalled, go to the landlord's bank and cash the check as a non-customer.  you will have to pay a small fee, but you will walk out with cash.  i suggest you take a photocopy of the check, and staple your receipt to it as evidence that the check was cashed for any impending legal proceedings.
