I see no legal reason why you would need a guarantor to sign a document to cancel your lease unless you are a minor. Under most lease agreements the lease expires by its own terms or automatically renews.I suggest that you carefully read the written lease that you are writing about to see who needs to sign what documents to cancel your lease assuming it has a term left. If there is a term left and you are leaving early before the total term to it expires and you have a guarantor as to it, then the guarantor should sign the release.Most likely the lease that you have has an early cancellation fee of $200 if you want out of the full term early. If so, then you are contractually obligated for the $200 if you want to end your lease early. Whether the $200 fee for cancelling the lease comes into play if the guarantor has not signed the release yet comes into play depending upon what your written lease states.
