MEP faces bankruptcy over remarks about Rotherham politicians and the town's child sex abuse scandal
Ms Collins, MEP for Yorkshire and North Lincolnshire, was ordered to pay £358,000 in damages and costs after a long-running legal battle ended at London's High Court in February.
But she appeared in court in Hull for a further hearing on Monday after she did not meet a 21-day deadline to pay the damages.
Sir Kevin Barron, MP for Rother Valley; John Healey, MP for Wentworth and Dearne, and Sarah Champion, MP for Rotherham, sued Ms Collins for libel and slander over a speech she gave at UKIPs conference in September 2014 - a month after a report found that around 1,400 children in Rotherham had been abused between 1997 and 2013.
The High Court heard she alleged that each of the MPs knew many of the details of the exploitation yet deliberately chose not to intervene.
She also expressed the opinion that they acted out of political correctness, political cowardice or political selfishness and were guilty of misconduct so grave that it was or should be criminal, as it aided the perpetrators.
Ms Collins argued that it was a political speech which did not contain any allegation of fact but expressed her opinion that the MPs were likely to have known that sexual exploitation was a serious problem in the area
Mr Justice Warby ordered Ms Collins to pay a total of £162,000 damages to the MPs and £196,000 in costs.
She was given 21 days to pay the damages and an interim payment of £120,000 costs but failed to do so.
On Monday, Ms Collins appeared at a private hearing at Hull County Court to discuss a demand for payment issued by the MPs' lawyers.
A spokeswoman for Ms Collins said the judge has now ordered an examination of her assets before June 8.
The spokeswoman said she will face bankruptcy proceedings if it is found that she cannot make the payments owed.
