Donald Trump's U.K. lawyers will be barred from participating in a future costs hearing at the high court in London unless the U.S. President agrees to pay nearly £300,000.

Judge Jason Rowley ruled on Wednesday that if the £290,000 ($361,263) legal fee bill is not paid within 28 days, his team will be prevented from addressing the court in April on a future argument about legal fees accrued in Trump's lawsuit against business intelligence company Orbis.
