My neighbor has been causing me a lot of trouble lately, so I want to make sure that he cannot escape our shared fence. How do I ensure that my neighbor is contained within our shared fence?

You could install taller fences or gates along the shared border that will prevent your neighbor from being able to climb or pass through. You could also file a deed restriction against the property which would require all future owners of the property to abide by. Any issues caused by trespassing from neighbors should be addressed immediately and any entry points should be secured to avoid further incursions. 
 Furthermore, you can consult with an experienced real estate lawyer who may be able to further advise on what steps you can take legally to enforce your rights as a property owner.
  I hope these tips help and best of luck!

You can ensure that your neighbor is contained within the shared fence by posting signs that read "No Trespassing" or "Keep Out" on the fence, in clear view of your neighbor. You can also secure the gate so that it cannot be opened from the outside and contact law enforcement if necessary.
