There may be someone that you don’t ever want to enter your property again.  Or there may be someone you don’t want to enter your property at all, even once.  In Massachusetts, there is a way to make it a criminal act if a particular person enters your property.   

A no trespass order formally advises the person that you do not want them on your property. 

Generally, the public is deemed to have an implied invitation to enter your property.  

They may walk in areas that would be regarded as usual places to approach the house located on a property.  It is perfectly legal for a person to walk up to your front door on the walkway, or even the lawn, and knock on your door to ask you a question, take a survey, or for any lawful reason.  (But, nowadays, some towns may have some limited restrictions on widespread door to-door solicitation or the like.)  

There are a few ways in Massachusetts to make this activity a criminal act, or a criminal trespass.  One is to post conspicuously placed No Trespass signs on your property.  This may be effective, but is probably not the type of message you would like to project to the community at large. Most people don’t mind the occasional door knocker, but seek to bar a select individual, or maybe a few, from even stepping foot on their property, let alone knock on their door.  The other way is to impose the Massachusetts criminal trespass statute.
