Tiffany Trump’s Inheritance from Dad Donald Trump Is ‘Not Necessarily Guaranteed’: Source

As newly leaked Howard Stern footage reveals that President Donald Trump once said his children Donald Trump Jr. and Ivanka tried to boot their half sister Tiffany Trump from his will, a source says Tiffany’s financial future is in no way guaranteed.

A source who knows Tiffany Trump — Donald Trump’s only daughter with second wife Marla Maples — says the 23-year-old has no promises from the former business mogul about what she could inherit after his death.

“She says she is not guaranteed anything, which is one of the reasons Tiffany and Marla have been so respectful of her dad and tiptoed around so much,” says the source.

Tiffany, who just began her first year at Georgetown Law School, made headlines this week when a 2005 recording obtained by Newsweek of her dad speaking to Stern on his radio show had Donald Trump admitting that his two eldest children tried to “bump” Tiffany from the inheritance.

And a source tells PEOPLE that Tiffany does not receive much financial assistance from her father.

“Donald paid for her college and gave her an apartment, but she did not get any allowance,” says the source. “She did ask her sister to talk to him about changing that though. Ironically enough they’re very close now.”

Growing up in Calabasas, California, after her parents split in 1996 and officially divorced in 1999, Tiffany “never lived the life of a rich person,” says the source.

“People assumed she was rich because of who her father was, but she always lived a very modest lifestyle. School was always covered but that was pretty much it.”

(President Trump has previously insisted he was “very generous” with Marla and Tiffany.)

President Trump has always seemed to have a complicated relationship with his younger daughter. For instance, in a phone call with Fox & Friends on Election Day, Trump said he was proud of Tiffany “to a lesser extent” than his adult children.

“I’m very proud of my children. I mean, I’m just looking at them right now, as an example for your show,” he said, according to Mediate. “But I’m very proud, because Don and Eric and Ivanka and — you know, to a lesser extent ’cause she just got out of school, out of college — but, uh, Tiffany, who has also been so terrific.”

Meanwhile, the source tells PEOPLE Trump and Tiffany were not close during her childhood.

“She had very little to even do with him. And that makes everything about her financial situation really weird and awkward.”

A spokesperson for the president and a spokesperson for the Trump Organization did not respond to PEOPLE’s requests for comment.
