Saying the offer was too low, the husband asked for it in writing and said he would discuss it then.
Just over two weeks later, the wife saw their property advertised in a local newspaper, allegedly listed with Century 21.
Niccol did not have a listing agreement for the orchard, nor had he sought permission to advertise or sell it.
The complainant was also concerned the details advertised were wrong and the price indication was "far below" what she asserted the orchard was worth.
She received an apology from Niccol after she approached Century 21 and offered to print a withdrawal and apology in the newspaper.
That was done and the woman confirmed she was satisfied with it.
The complaints committee said Niccol's conduct was a clear breach of the rules and found him guilty of unsatisfactory conduct.
Taking the apology into account, the committee found that a censure was "appropriate in the circumstances."
