2. Give the person notice

There are 2 main ways to give a trespasser notice that they are not allowed on your property:

• tell them directly
• put up a sign

Verbal notice or notice in writing

If someone keeps entering your property when you don't want them to, you can give them notice that they cannot enter. Once you've given them notice, it becomes illegal for them to enter or stay on your property.

There's no special form that a trespass notice needs to take. You can give them a piece of paper telling them not to come onto your property, or you can tell them verbally. It's usually better to give notice in writing, because it gives you evidence that you've given notice if you go to court.

When you give notice, make a note of the date and time you did this. One easy way to do this is to send yourself an email right away. This way, the time and date is automatically recorded.

Put up a sign

Another way to give notice is to put up a sign on your property. You can either put up a no-entrance sign, or a sign that says certain activities are not allowed. For example, you could say that dog-walking is not allowed on your property. The sign must clearly say that the action is not allowed on your property.

You can also put up a sign not allowing any access to your property for any reason, such as a “no trespassing” sign. Many municipalities also allow you to use a red circle on a white background to mean “no trespassing”, but many people may not understand what this means.
