David Paul Gammal sold or leased at least nine properties while working for a city real estate agency between March and November 2011.
His certificate of registration had expired in February 2010, but he had altered the date on the certificate when he began working for the agency in March 2011.
Mr Gammal ceased working for the agency when the agency was informed by Consumer Protection he was not the holder of a valid certificate of registration.
Mr Gammal was involved in the sale of properties in Landsdale, Morley, Wangara, Balcatta, Cockburn Central, Mirrabooka and Bayswater.
Acting Commissioner for Consumer Protection Gary Newcombe said the court case highlighted the need for all salespersons working in the real estate industry to be registered.
‘The licensing and registration system is essential in protecting the interests of consumers involved in home and land sales in WA,’ Mr Newcombe said.
‘Particularly when salespeople are re-entering the industry after a period of absence, they need to ensure they have the proper certificates in place before they start selling property.’
