Mr. Sarno is licensed to practice law in NJ and NY. His response here is not legal advice and does not create an attorney/ client relationship. The response is in the form of legal education and is intended to provide general information about the matter in question. Many times the questioner may leave out details which would make the reply unsuitable. Mr. Sarno strongly advises the questioner to confer with an attorney in their own state to acquire more information.
If you are an experienced landlord you can file our own eviction but it can be VERY TRICKY because of procedural requirements. One risk is that if you screw up a notice requirement or other procedural matter, the eviction will fail and you have to start over - meanwhile the tenant is still in possession. SO, the best advice is to get a Landlord/Tenant attorney to handle it for you. You should also be very careful not do do anything that deprives the tenant of possession, water, utilities, etc. This kind of "self help" can get you counter-sued for constructive (wrongful) eviction. The landlord has to take the high road at all times - an experienced attorney in your area should know the ropes.
