Thank you.

You can do two things here:

1) Tell them to stop coming to the property. You are the owner and you can tell them not to visit. While this sounds harsh and may become an issue with your wife, in the end, it is your decision as to who comes to the property. Since your wife is not on the deed, she cannot make this decision. If push comes to shove, you can call the police and ask them to escort them out. While often the police may be wary of being involved in a family matter, this may be the fastest way to resolve them being there and causing issues.

2) As for general interaction, this is much harder to stop. You can file a restraining order against them if they threaten you, and you have reasonable apprehension of bodily harm from said threat. Any of the following elements would do:

-threatens your safety
-follows, approaches, or confronts you
-appears near your home, place of employment, school, or other place where you normally can be found
-causes damage to your home or property
-places an object on your property, either directly or through a third person,
-causes injury to your pet, or
-communicates with you in such a way to make you afraid.

Section 633:3-a Stalking

Often, the mere threat of filing such a restraining order does wonders to "cool" their approach to you, even if in reality, the request may not be held up unless the Court finds that such behavior has occurred.
