Legal Question in Real Estate Law in New Jersey

Pay the rent. The lease probably says something about each of you being responsible for the full rent, so the landlord doesn't have to look for 50% from each of you. The landlord can go after either or both of you for non-payment.

You may also try to work something out with the landlord, permitting you to get a new room-mate who will pay the rent. Your room-mate has moved out, hasn't s/he?

THIS RESPONSE IS NOT LEGAL ADVICE, SINCE I DO NOT HAVE ALL OF THE INFORMATION THAT WOULD BE REQUIRED, AND I DO NOT HAVE A REPRESENTATION AGREEMENT WITH YOU.

* If the answers to your question confirm that you have a valid issue or worthwhile claim, your next step should almost always be to establish a dialog with a lawyer who can provide specific advice to you. Contact a lawyer in your county or township.

* Another reason for contacting a lawyer is that it is often impossible to give a good answer in the Internet Q&A format without having more information. The unique circumstances of your situation and things that you may not have thought to mention in your question may completely change the answer. If you want to be sure that you have a complete answer to your question and an understanding of what that answer means, establish a connection with a lawyer who practices in the area of your concern.

I agree with the previous answer.
