My husband and I sold our condo on 4/8/2015. Today we received in the mail at our new address an invoice dated 6/1/2015 for "Condo fee for snow removal expense" in the amount of $175.00. Our position is that we don't owe it since it was not presented in the closing documents. We were cleared to close, so our thought it that would not have happened if there were any outstanding fees or assessments due. Are we correct?
