If a company pays you by mistake and you have already spent the money, they have the right to ask you to return the overpayment. You may be required to repay the amount, even if it means you have to make arrangements to do so over time. Failure to return the overpayment could result in legal action being taken against you.
Theoretically the money goes to the company whose stocks you have bought. But, pratically it goes to the person who sold the stocks. When you buy the stocks you buy ownership of that company from the person who already held it. It is like transfer of ownership.

You get your property back and get to keep any money already paid for it.
The mortgage company gets the money.
They can keep the money you already paid.
Need the right answer
I really recommend calling your mortgage company to ask.
Because when people buy stock, that means they are paying a company a sum to have the right to own a part of that company. When this happens the value of the company goes up. However if people do not like a company they will sell the stock they own and get money back for it. When this happens the company now holds less money and its stock goes down. This happens with thousands of listings everyday on the stock exchanges.
You are responsible for any money that is present in your account. If you feel some transaction (a deposit) has happened in your account which you are not aware of, you must notify the bank of the same. If you happen to hold on to this money and it so happens that this money was being used by terrorists and they put it into your account by mistake, you will also be in trouble. So it is better if you intimate the bank reg. this.
write them a check for the amount and they'll cash it and you'll be paid back
I suggest that you call the company and see if they made a mistake. If they saw they didnt then explain to them that you never got it. If they still continue to deny it, you can go threw all the trouble to sue them
If the incident happens because of the carelessness of the customer in protecting his logon id and password the bank is not responsible. If the incident happens due to some mistake in the bank system then it is liable.
