If Melania & Donald split hits the fan

RUDY AND JUDI are splitsville. Former Mayor Rudy Giuliani and his wife of 15 years, Judith, are getting a divorce.

Judith Nathan filed for a contested divorce on Wednesday in Manhattan Supreme Court, signaling a fight over assets. They are each headed for their third divorce.

The reasons for the separation were unclear.

“How’d they stay married for 15 years? That’s a better question!” a source close to the former mayor said.

The estranged couple was in the headlines just last month, when Axios reported that Giuliani had made a tasteless joke at Mar-a-Lago about Hillary Clinton that bombed with Judith, 63.

“Hillary was also here,” Giuliani, 73, said to a room of Republican donors, according to Axios. “And she actually fit through the door.”

Judith, a registered nurse, reportedly gave her husband a “most foul look.”

President Trump later told the crowd, “I’m just glad I didn’t say it.”

Giuliani had two kids, Andrew and Caroline, with his second wife, Donna Hanover. Hanover and Giuliani were married for 20 years. Prior to that, Giuliani was married for 14 years to his second cousin, Regina Peruggi.

Judith has a daughter, Whitney, from a previous marriage.

Giuliani famously fell for his wife at a cigar bar in 1999 while he was mayor and still married to Hanover.

Giuliani and Judith kept their affair secret for a year before he announced their love to the world — and Hanover — during a news conference.

“Judith Nathan is a very, very fine person,” the Republican said at the notorious presser. “She’s been a very good friend to me.”

Giuliani’s split from Hanover was so acrimonious that in 2001 a judge issued a temporary restraining order barring Judith from Gracie Mansion.

The News broke the story in 2007 that Judith had been married twice before tying the knot with Giuliani — not once, as she initially claimed.

“Hopefully if you learn anything from being married before, it’s that you learn from your mistakes. We look forward to growing old together,” Judith told The News at the time.

Efforts to reach Rudy Giuliani were unsuccessful.

A spokesman for Judith Guiliani said, “She is thankful that she was able to be by Rudy’s side on Sept 11th, 2001, and help establish the Family Center at Pier 94 which supported the victims' families for several months, and also be a founding board member of the Twin Towers Fund. As a nurse she found this particularly gratifying.” WHAT HAPPENS if the White House becomes the spite house?

Should a President and First Lady get divorced, who would get to call 1600 Pennsylvania Ave. home?

It’s uncharted territory, since no American President has ever gotten a divorce while in office.

But eight high-profile lawyers, who either specialize in matrimonial law or have worked on a major divorce case, offered their opinions to the Daily News — as a hypothetical, emphasizing the likelihood of a Trump divorce was slim to none.

Several told The News it’s typically impossible to kick an estranged spouse out of the marital home, but that President Trump’s commander-in-chief status might give him unusual power over Melania’s access.

“I think the President could do whatever the President wants,” said Raoul Felder, who represented former Mayor Rudy Giuliani in his divorce from Donna Hanover. Felder unsuccessfully fought attempts from Hanover to bar the ex-mayor’s future ex-wife, Judi Nathan, from Gracie Mansion.

“The President could put anybody out of the White House,” added Felder, explaining Trump could say, “‘I want the marshals to surround the House and I don't want her to come.’”

Rebekah Sullivan, a Washington, D.C.-area divorce lawyer, pointed out the difficulties in booting a spouse out of the house, but agreed that Trump's security detail complicates this precedent.

“He would have that same issue that everybody else has — how do you force this person to leave? — but he would have the marshals or military or Secret Service or whoever he’s using to help him enforce his (decision),” she said.

Cheryl Hepfer,who also practices in Washington, D.C., said the White House’s status as a government property could undermine Melania’s potential claims to residency rights.

“The Trumps don’t own the White House — it’s owned by the people of the United States of America,” said Hepfer, past president of the American Academy of Matrimonial Lawyers.

“So I don't believe that Mrs. Trump would have the right to secure the residency of the White House if there were divorce proceedings.”
