Las Vegas police said Thursday that guards at Newton's house refused to accept documents, and moving vans and Clark County sheriff's civil division deputies left after less than 45 minutes.
Police say the case now returns to Clark County District Court, where a judge last June ruled that Newton owed his former pilot more than $400,000 in back pay.
A lawyer for pilot Monty Ward told the Las Vegas Sun the amount due topped $501,388 last month and is growing at more than $125 per day.
Ward's lawyer, John Muije (MEW'-jee) and Newton representatives did not immediately respond to messages from The Associated Press.
