Local Boards of Health do not always timely file liens on properties. The title insurance only covers recorded liens. The title company will make all efforts possible to identify any liens that could cloud the Title. These charges will be paid by the seller at closing in order to provide clear title at the date of closing.
It is in the interest of a buyer to check with the local Board of Health to make sure there are no outstanding bills that have not yet been recorded. This is the same with sewer liens. Also, if the subject property is a newer build, it is in the interest of your buyer to check if the assessed taxes are correct.
Notify the Title Company with written records of any pertinent information.
