Where are you finding the incorrect information Dream? If it is in your MLS listing Bob is correct, your Realtor can update that for you. If it is on the county website you'll need to contact them directly.
Hi, Is your home currently on the market for sale? If so, I would have your agent look to make sure they have the property pointed correctly on our MRIS system. Unfortunately, we have little control other than listing remarks, address, etc. as to where Trulia lists school information. Your agent CAN make a note of it in the REMARKS section of their listing on Trulia.
