Hunter Biden’s baby mama has lit the touch-paper on next week’s courthouse showdown – by accusing the president’s son of hiding assets and posing as a ‘destitute’ artist to get his child support payments slashed.

Lunden Roberts, 32, wants to know how Hunter can plead poverty in their paternity case while deploying a stable of super lawyers charging up to $855 per hour in his various lawsuits and congressional probes. 

She’s arguing that attorney-client privilege does not shield her 53-year-old former flame from having to reveal precisely how much he’s shelling out, and to whom.

Roberts further accuses Hunter – who spent this past week at a Democrat donor’s $50 million California vineyard – of vacuuming up perks, loans and non-cash benefits from rich pals but not declaring it as personal income.

The huge sums involved will paint a ‘very different story’ about the First Son’s finances, her attorney Clinton Lancaster claims in a motion filed Thursday in circuit court in Independence County, Arkansas.

Cutting the money Hunter contributes to four-year-old Navy Joan Roberts’s upbringing would therefore be ‘inappropriate and unjust’ – and the dad-of-five should instead pay more if he’s caught hiding his true wealth, the filing argues.

‘Voluntarily reducing income, or hiding assets, is not a basis for a reduction in support,’ warns Lancaster.

‘The court must consider whether the defendant has unclean hands or is otherwise perpetrating a fraud upon the court regarding his income.’

Hunter was ordered to appear before Judge Holly Meyer for a contempt hearing this coming Monday in rural Batesville, Arkansas, after Roberts suggested he be slung in jail for not complying with discovery deadlines.

The pair appeared to have put their dispute behind them in 2019 when a DNA test proved Navy Joan was his daughter and he agreed to a reported $2.5 million settlement.

But the recovering drug addict abruptly reopened the case in September by claiming he had suffered ‘a substantial material change’ in his income and couldn’t afford the payments.

Furious Roberts refused to buckle and raised the stakes by petitioning the court to officially rename her daughter Navy Joan Biden to ‘benefit from carrying the Biden family name,’ a move Hunter dismissed as ‘political warfare’.

She hit him with a discovery request containing hundreds of questions covering his assets, earnings, overseas business dealings in Ukraine and China plus a list of people who bought his artworks after he reinvented himself as a painter.

Lancaster’s latest motion takes aim at the pricey legal team comprising ‘some of the most expensive attorneys on planet Earth’ that Hunter has assembled to fight multiple lawsuits and ongoing federal and congressional probes.

These include Washington ‘power fixer’ Abbe Lowell ‘who charges a rate of $855 per billable hour’, according to the filing, and whose past clients include Bill Clinton, former vice-presidential candidate John Edwards, and Jared Kushner.

Also listed are prominent Chicago attorney George Mesires and Hunter’s ‘sugar brother’ pal Kevin Morris – who reportedly loaned him $2.8 million to pay off a 2021 tax bill and has represented Hollywood stars Chris Rock, Scarlett Johansson and Matthew McConaughey.

‘The plaintiff has evidence that the defendant has not fully disclosed his income sources, residences, assets, and property,’ Lancaster states. ‘This evidence is bolstered by the fact that the defendant refuses to provide full discovery in this matter.

‘What Mr. Biden has paid, or received as a contribution, for paying these elite attorneys has a definitive and quantifiable value that goes directly to his income for child support purposes.’

Lancaster argues that privilege does not apply to client identity and fee information and even wants to see how much Hunter is paying Brent Langdon, the lawyer representing him in the paternity suit.‘

‘Mr Biden claims to be nothing more than a Yale educated attorney/artist who is somewhat financially destitute and needs his child support adjusted. However, for an artist living on meager means Mr Biden is living lavishly,’ he continues.

His remarks about Hunter’s home and car are redacted but he notes that Hunter jets around the world on ‘the safest and most comfortable airplane in existence – Air Force One.’

Only someone with ‘the ‘prestige, power and influence associated with the name Biden’ could land such a peerless legal team, bolstering Roberts’s case that Navy Joan would benefit from taking her dad’s name.

‘Payments to attorneys will show … there is no difficulty that a person with the last name “Biden” cannot fix with a Biden-paid or funded attorney,’ Lancaster adds.

‘These payments will evince that there is respect, admiration, power, accolades, and not harassment or hardship due to the name “Biden”.’

Hunter’s lawyers filed a request for a continuance Wednesday afternoon, pleading for more time to ‘properly prepare’ for Monday’s showdown, but it was denied by Judge Meyer. Langdon claimed that his client needed longer because Roberts has retained Garrett Ziegler, a former Trump administration staffer and longtime Hunter nemesis, as an expert witness.

He dropped his motion to exclude Ziegler Friday morning and suggested the court ‘might consider rescheduling’ or canceling Monday’s hearing as a key issue had been cleared up.

Langdon recommended a phone or video conference instead to save ‘time, expense, logistical challenges, and especially the media event any in-person hearing would create.’

But his appeal fell on deaf ears as Judge Meyer ruled that Monday’s hearing must take place and that ‘all parties are to physically appear for all future hearings.’ 

In a final throw of the dice Langdon asked late Friday if Lowell – who has previously played no part in the Arkansas proceedings – could ‘participate on behalf of Hunter Biden.’ 

Navy Joan was born in August 2018 but she remained a secret until Roberts sued Hunter for child support in her native Arkansas.

The adorable, blonde-haired girl is the fourth of Hunter’s five children but neither he, nor his parents Joe and Jill Biden, have ever met the child or publicly acknowledged her existence.

 Hunter claimed during the original 10-month paternity case that he was ‘unemployed and had no monthly income’ despite living in a $12,000-per-month Hollywood rental and driving a Porsche.

But when a judge ordered him to produce financial records he repeatedly failed to do so and instead settled out of court, the two sides announcing a ‘global, final settlement of all issues’.

Hunter claimed in his 2021 memoir, Beautiful Things, that he went on such a ‘rampage’ in the wake of his 2017 divorce from Kathleen Buhle that he couldn’t remember the names of the women he bedded.

‘It’s why I would later challenge in court the woman from Arkansas who had a baby in 2018 and claimed the child was mine – I had no recollection of our encounter. That’s how little connection I had with anyone,’ he wrote.

It was initially reported that Hunter met Roberts while she worked as a stripper at a DC club which Hunter frequented.

But texts retrieved from his notorious abandoned laptop proved that she was in fact on the payroll at Rosemont Seneca, Hunter’s investment firm.

She and Hunter conceived Navy Joan around December 2017 while he was still in a relationship with his brother Beau’s widow, Hallie, but he stopped responding to her texts during the pregnancy.

Hunter has never seen Navy Joan and could not pick her out of a photo lineup, according to court filings.

And Navy has never met her grandpa Joe, 80, despite the President fawning over his six other grandkids and frequently bringing them along for events and speeches.
