A guy scammed me, but he gave me a bank account number & routing number. Can I use that to take out what he owes me?
You're potentially in very deep water here. You don't know who this person is that you're dealing with.  Before you'd even met him, he just gave you his banking info, seemingly without a second thought.   You have no idea what the sources of his money are, so what happens if the money is stolen or otherwise illegal?  If it is determined that you used any of that money, you'll be on the hook to return it, at the very least.  Who knows what the legal ramifications are either? So it sounds like you began spending his money before you had any kind of written agreement in place?  Doesn't that seem odd to you to have someone just so trusting as to not even ask for that? Was the source of the email about the $2500 from PayPal, or from him or his advisor?  PayPal always sends you a notice directly when funds are received into your account, and even if they were going to put a temporary hold on them for whatever reason (sometimes they do that), it would still show up in your account. I would HIGHLY (can I be more emphatic?) advise you not to go anywhere NEAR his bank account until or unless you can absolutely verify who he is, where his money comes from, and what the situation is. If you start dipping into his account, whether you think you're somehow entitled to the money or not, he could cry foul and have you arrested for theft. This is a very odd situation, and for someone who says he's normally cautious and skeptical, you sure let your guard down here when you started spending his money without making any serious effort to confirm his bona fides. Just because he passes himself off as smart and the "doctor type" doesn't mean squat.  The very best scammers can do that (ever see the movie "Catch Me If You Can", based on a true story?), so you have no basis for knowing he's anything at all. I am thoroughly confused as to why you'd just willfully start using his money without knowing anything about him.  That's deeply disconcerting, because you've opened yourself up to a world of potential criminal and civil liability if this situation goes south. If this guy was giving you money as an investment in your business and you instead used some of that money for your own personal expenses then you could land in very serious trouble for co-mingling of funds.  Even if he told you it was okay, it doesn't sound like there's anything in writing, so he could just as easily deny giving you permission to use the money that way and have you charged with embezzlement. You need to step back, take a deep breath, stop using his money, and contact a lawyer for advice.  Every attorney will give you a free consultation, and you need to protect yourself here. Be careful, my friend.  If this makes you suspicious then you need to listen to that voice in your head and find a way to get out of this situation.
