Also keep in mind that dating from the early 1990s as his father was dying, Trump made an attempt at cheating his siblings from their share of inheritance from his father's fortune. Even his Alzheimers addled father somehow recognized something was afoul with paperwork Trump tried to trick him into signing, refused to sign it and led his wife to contact the other siblings who then found out about the ploy. At that point, the siblings all realized that the set of businesses had already been redirecting wealth out of Trump Senior's business entities through shell janitorial service companies in New Jersey into Trump's entities to avoid estate taxes and all of the siblings at that point signed on to continue that scam. At the time the father died, his business, previously valued by the Trump family at $1.3 billion had been hollowed out completely and was worth a mere $30 million dollars

SNIP In December 2003, it was reported that Trump's four surviving children would sell the apartments they acquired in 1997 to an investment group led by Rubin Schron, priced at $600 million;[143] the sale occurred in May 2004. The 2016 leak of Donald Trump's tax information from 2005, which showed an income of $153 million, prompted The New York Times to investigate, leading to the 2018 exposé.[120][u] The Times reported that the properties sold in 2004 were valued over 16 times their previously declared worth.[102] Fred and Mary reportedly provided their children with over $1 billion altogether, which should have been taxed at the rate of 55% for gifts and inheritances (over $550 million), but records show that a total of only $52.2 million (about 5%) was paid.[102] According to New York State law, individuals can be prosecuted on the basis of intentional tax evasion if a fraudulent return form can be produced as evidence; the statute of limitations does not apply in such cases.[145] By February 1, 2019, Maryanne Trump Barry was being investigated for possible judicial misconduct regarding the schemes, but this was mooted later in the month due to her retirement.[146]SNIP ~Wiki en.wikipedia.org - Fred Trump

Avoided 500 million in dubious inheritance tax schemes, and Maryanne retired to avoid prosecution. I wonder what Donald was trying to get Fred to sign?
