Ex-con former first son Hunter Biden may have to shell out more in child support to his former stripper baby mama, given his alleged lavish lifestyle featuring gourmet food and a mountain home with ocean views.

An Arkansas judge Thursday ordered Biden, a 56-year-old dad of five, to turn over his tax records and other financials and sit for a grilling under oath by lawyers for Lunden Roberts — with whom he shares 7-year-old daughter Navy Joan Roberts.

The ruling came as part of Roberts’ bid to have Biden start coughing up more than the $5,000 a month he currently pays her in support, since his “style of living is higher than it was previously,” Roberts’ lawyer, Clint Lancaster, argued during a video hearing, according to a transcript obtained by The Post.

Neither Roberts, 34, nor Biden were present for the oral arguments.

The fact that Biden lives in a stunning home “on the hill overlooking the ocean” in California was one of several clues showing he has more money than he did when he settled with Roberts in 2023, Lancaster argued.

Hunter’s trips overseas and meals at posh restaurants on Nantucket, a tony playground island for the rich and famous off Massachusetts, with his ex-president dad Joe Biden and stepmom Jill Biden also indicate the child-support payments should be increased, Lancaster claimed.

Navy is at the age where she has started to realize that she is a living a very different lifestyle than her estranged half-siblings, Lancaster previously argued in court papers.

Biden has four other children — three of whom he shares with ex-wife Kathleen Buhle and one he has with current wife Melissa Cohen.

Biden’s lawyer, Brent Langdon, fired back by arguing that his client is living in the same home he did at the time of the agreement and that it’s a rental his landlord renovated after the fires. During that time, Hunter was temporarily forced to move out, Langdon said.

“I just don’t think going out to dinner is a support for modification of child support when you are already paying … at least double the amount, that under child support guidelines, you should be paying,” Langdon said.

Judge Holly Meyer ruled that Roberts is at least entitled to look at Biden’s recent tax records and have her lawyers depose him to find out if he’s making more and whether his payments should increase.

Earlier in the hearing, Biden clinched a win when Meyer agreed to dismiss Roberts’ bid to hold him in contempt — and have him thrown in jail — over paintings he made and promised to give to Navy.

Roberts and Biden have been squabbling over a clause in their settlement agreement that Navy can choose 30 of artworks by Biden by June 2026 and then keep or sell them.

The judge agreed with Biden’s camp that since the June 26, 2026 deadline hadn’t lapsed yet, Hunter still has over a month to fulfill his commitment and that the contempt motion was filed too soon.

Langdon informed the judge that Navy was already sent 10 of Biden’s works and another 47 had been shipped and were en route to her now, for her to choose from.

Lunden reopened the since-settled case in January in a bomshell lawsuit alleging Biden “ghosted” Navy.

But Meyer acknowledged during the hearing that she can’t force parents to have contact with their kids.

“I’ve been doing divorces and custody for many years now, and I cannot make someone communicate with their child or be a parent in the emotional, supportive sense of the word,” Meyer said. “Failure to communicate is not going to be grounds for contempt.

“Those are choices that Mr. Biden has made, and he is free to make.”

Biden was convicted in 2024 of charges related to lying about his drug use to buy a gun. He also was convicted that year of federal charges for dodging $1.4 million in taxes.

He was later given a rare “unconditional” pardon by his dad in both cases before President Biden left the White House, meaning there are no lingering repercussions for Hunter involving either conviction.

Lawyers for Biden and Roberts did not return Post requests for comment.
