Shia LaBeouf's uncle has been ordered to repay $800,000 which he borrowed from the actor.

According to the New York Daily News newspaper, the judge wrote in a decision signed Monday but posted on Wednesday "The terms of the note are clear and the amount due and owing ... is forth in the note."

The pair had an agreement which stated Barry should repay the loan in 15 instalments of $53,333 but he never did and he is now set to give as much as nine per cent interest.

Saide runs an employment agency and borrowed the money following the recession to help him get back on track.

When the lawsuit was filed last August, Barry expressed surprise about the 27-year-old actor's actions insisting he wouldn't have borrowed anything if he thought this would happen.

In an affidavit, he reportedly said: "Had I thought that Shayne and Shia would take this extraordinary step and seek to impoverish me, I never would have borrowed a dollar from Shia."

Barry also insisted he spent money looking after the Hollywood hunk and his mother Shayne before his rise to stardom.
