You should first obtain prior written consent from the property owner, clearly including your name and CEA registration number. Make sure all details in the advertisement (floor area, tenure, descriptions) are accurate and never misleading. Include your name, CEA registration number, contact number, and the estate agent’s licence number in the advertisement. For signboards on the landed property, get the owner’s written approval and comply with any local authority requirements before putting it up. Remove or update the advertisement promptly when the property is no longer available.
