After the Real Estate Demand Bill is issued and not paid, this letter is mailed to the taxpayer as a courtesy. Failure to pay will lead to a Notice of Tax Taking Advertisement in the Brookline Tab, and a public notice posting in Town Hall and the Main Library. By operation of law, the Town must advertise and post these notices. The fee for the advertisement is added to the outstanding tax bill. If not paid, a lien is placed on the property and the fees associated with recording the lien are added to the bill. For more information, see MGL Chapter 60, Sections 37, 53, 54, 55, and 60.
