Adams was once the golden girl of Bayleys, making millions in commission and becoming its top seller. She left the company abruptly last March and weeks later started work with Sotheby's International.
Questions about her behaviour at Bayleys were raised in January last year after she sold a four-bedroom home in Palmer Cres.
Adams, the listing and selling agent for the property, was accused of planning to help buy and renovate it so it could be resold "for a quick profit".
Bank records show she lent buyer Geoff Harriman $187,250 to ensure the $1.7 million sale went through in 2010.
They were subsequently listed as registered owners along with a trust, JMAR, of which Adams was a trustee.
Bayleys terminated her contract and, as legally required, advised the agents' authority of their concerns.
At the tribunal her lawyer, John Billington QC, acknowledged she was guilty of breaching her obligations, by not telling the owner she had lent money to Mr Harriman or asking for consent to do so - actions that were reckless not wilful, he said.
