How would Mary Trump get a hold of her uncle’s tax return?
The ex-president’s niece allegedly shared her uncle’s documents that she received during the legal discovery during the estate battle
In another part of the article it says
Donald Trump had accused his niece of violating a non-disclosure agreement reached after a feud over the estate of Fred Trump – the ex-president’s dad and Mary’s grandfather. But Mary Trump’s attorneys said that under state law the agreement was “terminable at will” and unenforceable because it didn’t explicitly say the deal was permanent.
Therefore, there are 2 reasons to keep the information private. An expectation of privacy and a non-disclosure agreement. Both are not worth anything if they rule against Donald Trump.
Can you imagine if every contract is invalid if you don't say the deal is "permanent"?
That's a bit of a stretch in my opinion, but I am not a lawyer.
