It may sound crazy but a Demand Letter from an attorney to a tenant who has fallen behind on payments of rent and CAM charges can be more effective than a dozen late notices and Notices to Quit by a landlord.  We have over 30 year experience in helping landlords enforce leases and obtain the payments that are due.  Most of the time a Demand Letter or filing of a lawsuit will be sufficient to get payments up to date. Unfortunately there are times when litigation is required and you need an attorney like The Law Offices of Lee M. Herman, Esquire to be on your side an aggressively protect your interests.
