Likewise, what happens if I cash a check I found?
Legally speaking, no. The individual will most certainly get turned away at a bank, though an ATM machine may incorrectly accept the check (it may be retroactively rejected by the bank). It is important that you cancel the check to ensure that it is not cashed by someone else.
Likewise, can you cash a check that's not in your name? It's theoretically possible but pretty unlikely that you'll be successful if the check is very big. This would be done by having the payee endorse the check (sign the back) and below that write "PAY TO THE ORDER OF JOHN SMITH", and then John Smith can endorse and then cash or deposit the check.
Likewise, can you cash a check that you find?
If it's payable to you then yes you can cash it. If it's made to someone else then its not yours and you should return it. There may be a reward. Cashing it if it's not yours is likely to get you some prison time
What do I do if I find a check?
Contact your bank or credit union right away. State law generally provides that you are not responsible for a check if someone forged the signature of the person to whom you made out the check. Tell your bank or credit union what happened and ask for the money to be restored to your account.
