I'd hope they'd let me keep the accumulated interest, at least! I'd probably call them and ask what gives. You KNOW they'll retrieve the accidental deposit. We always tell military personnel and their wives that if they find extra money, NOT to spend it because it WILL eventually be taken back, and oftentimes a lot quicker than it was given.

I will let the bank know the error, but if they refuse to take it back, then I will keep the money in my account, but will no spend it. Yes, they will eventually take it back.

I'd create a frivolous lawsuit against the bank when they pulled the money back out of my account citing various forms of psychological anguish the incident had caused. That's the American way!

Just kidding, obviously I'd notify them and be sure not to spend any of it.

A similar thing happened to an old client of mine, it wasn't a bank account but a brokerage account. An IRA actually. One day he checked his account online and noticed his account was suddenly about 170k more than it should be. We of course notified the proper party and waited for it to be transfered back out.

Anyway, it took over a month for them to rectify the problem. It happened to be a rollover deposit that had one number transposed.

I would certainly be honest, but I would pray that they would let me keep the interest.

Depending on the interest rate I was getting, I'd move it to the high interest account. When the bank finally figured out their mistake (and I'm sure they would), I'd give the money back to them (minus interest). I don't think you are under any legal obligation to report the bank's mistakes, but I think I'd check into that with a lawyer.

Some may say that keeping the interest is wrong. Well ask yourself if a company, that short-changed you, ever offered you back interest. More than likely you had to wait 4-6 weeks for a check to get cut -- with no interest.

I've spent enough time on the phone with customer service representatives correcting errors that hurt me. I think it'd be up to the bank to catch up with me at my convenience. What's good for the goose is good for the gander right?

Well we all know from Monopoly that a bank error in your favor is worth $200.

I wouldn't move the money or anything because I think that would make it a bit more obvious that they made the mistake. I would request to keep the interest that accrues, at least as a thank you for not spending the money.

I'd keep the interest or at least ask to keep it if they tried to take that back as well. It's an error on their part.

The other option is to very quickly drop the money into a numbered account in say the Caymans, bounce it between a few institutions that don't divulge banking information and retire... but that's theft and requires a lot of effort.

MoneyFwd, I like the way you think. I will change my answer to moving all but my 1M to another account and setting up an automated money check for the interest to myself or another account. Neither of these are big transactions (unless you have a lot of money in the account to begin with) that would draw attention. And when the bank finally realizes their mistake, they wouldn't be able to get more than the 1M of their mistake.

Hmm, perhaps you can slowly move money to another account in an automated way, perhaps 1K a day or something, without drawing attention.

I wouldn't play around moving the money. I'm sure the depository agreement gives the bank the right to reverse the trasnaction - what would happen if the money was missing - mighty big bounce!
I'd notify them immediately and let it be.

It would be so tempting to try and tranfer the money to an offshore account... But in the end, I would probably notify the bank of the error. I like my life. I do not have any intention of spending the next 10 years of my life in a 10x10 cell with a man named "Teabag".

It's our duty to report the error to the bank as soon as possible. If the bank drags its feet on fixing the error, than the least they can do is let us keep the interest. However, I wouldn't spend the money on karma principles -- it isn't my money and I did nothing to earn it, so spending it is tantamount to stealing and I don't want that to come back to bite me. It's not worth it.

If I saw $1M accidentally appear in my bank account here is what I would do:

1. Do a big time happy dance.
2. Allow the euphoria to subside
3. Explain to my wife why I was doing the happy dance
4. Listen to her tell me that I need to call the bank and have this corrected as soon as possible.

Now, I know when opportunity knocks and I know the money will soon be gone so...

I would find a short term guaranteed interest certificate, make a few bucks and await the banks "nasty call".

Sure, I would give it back but I would let as much interest accumulate as possible.

Hmmm...Maybe try to delay the return of the money by taking things to the court system.

Other ideas:
Get the money off-shore and retire to a tropical island :)

this just happened to me! but the deposit was only just over a grand though.

i havn't told the bank yet as i want to check its not a donation to my christmas car fund from a kindly relative that wanted to remain annonymous for the time being but then will send a card explaining it all on the big day!!

seriously, it did cause me joy and then anguish as, untill a few months, ago i had almost that same amount in the account. as i'd forgotten some fees had gone out of it, for a few hours i was really happy and started planning 'better' presents for my family. then i remembered paying that fee and realised the mistake. good job i didnt go shopping in the interim. damn bank.

I'd have to return it to the bank and hope for a reward (however small or marginal).

If they did it by mistake, and I noticed, then I would comment. I would say, "It's about time my money shows on a Savings account, that way I could withdraw my money by the thousands."
Since, in fact I have a few million, I would expect to deposit that money also.
If the bank manager agrees to this, I would let them keep a thousand to make up for this one mistake.

This happened to me, but with a smaller amont of money ($5000) and the bank did not take the money until eight months later.
It is actually a banking trick - to get rid of "high risk accounts"- whuch is what I later found out from one of the banks collection severvice agents. It really sucks it is better to move your money to another account and leave the banks error in the banks hands.
