I have received a court order from the supreme court to stop my ex from spending monies received from a lawsuit. I don't know what bank he is using. I need to make sure he is not using the money.

The Supreme court of what?

You hire a private investigator and see if they can find out. If you had a case being heard by the supreme court (which I find very unusual because they don't hear divorce cases) you had to have had really good lawyers.....and they didn't tell you this? Something here isn't adding up.

Any question on law needs to include your general locale as laws vary by area.

But smoothy makes a valid, even state supreme courts don't hear divorce actions. If you don't know where the funds are how do you know they exist? The court would also issue an injunction to prohibit him from spending money, this would be served on him directly.

So this is not making real sense.

Was discovery in court not done to find her bank? Was she served to show where the money was" what has your attorney said to do?

I will also ask, what Supreme Court, you would have to had to know all of this, and spent 1000's getting to a state Supreme Court

In some states, New York for example, the trial court of general jurisdiction is called a supreme court.

But OP says it's "monies received from a lawsuit". Which means that the opposing party wrote a check to the ex. Simply find out if that check was deposited and, if so, what bank it was deposited to. If it was cashed, however, OP may be effectively out of luck.
