Can you endorse a check for someone else to deposit in your account?

Yes, you can endorse a check for someone else to deposit in any account, yours or his or some random person in the Middle East. Once you endorse the check, it is considered "as good as cash" unless you write "For Deposit Only" on the back as well - then it must be deposited into a bank account somewhere. If you trust the person who will be depositing the check, feel free to endorse the check and let them take it to a bank or ATM for depositing into your account - they will need your bank deposit slip or your bank card with PIN to do so.
