Is this Lot realy mine

[Shiri Manor Nisenbaum]

Hello friends

On November I bought a house in Fulton county. Last week I got a letter from the county regarding tax assessment on the house as expected. However I was extremely surprise to get also tax assessment to a lot near the house. I called the county tax office and they said that on the transaction I did both house and nearby lot purchased by me. The lawyer that did the transaction says we did only the house.

Did anyone had such case? How can I find out if the lot supposed to be mine or someone did a mistake

Thanks, Shiri
