Method of official notification to an individual or the public that specific event is about to occur. Legal notice is whatever method is legally specified for official notification. Legal notice can include a registered letter, advertisement in a designated newspaper, telegram, or other methods. For example, a homeowner seeks a variance to add a bedroom and a kitchen for the purpose of providing an apartment for a family member. The municipal code specifies the homeowner must provide legal notice to adjacent property owners by registered letter the date the variance hearing will occur.
