How can I sign a check that doesn't belong to me?

You cannot sign a check that does not belong to you. If you see a check, it must be addressed to you, and you can either endorse it (put your signature on the back) or deposit it into your account. You must not deposit any check that you did not generate yourself. This is considered fraud, and can lead to serious legal repercussions.
