The lawyer, according to the standards committee, told it he did not recall saying that he did not believe in file notes.
The case the lawyer was involved in related to a $50,000 deposit used to buy a residential property.
The committee said that the judge had raised concerns about the lawyer's decision to act despite a risk of a conflict of interest.
The lawyer's position, the judge said, was "compromised to a degree by the various interests he is serving" and that "there are obvious conflicts of interest which, when combined with the lack of file notes, suggest his evidence should be the subject of careful scrutiny," according to the standards committee.
The standards committee was concerned that the lawyer continued to express a belief that file notes were unnecessary.
The lawyer's record keeping was "inadequate" and the committee said he had "not maintained proper professional standards in this regard".
