Transferring lease contract to LLC

[Eddie Ziv]

Here is a question for all of you legal eagles out there. I'm in the process of transferring my properties to a newly formed LLC. All my lease contracts that were done by the management company representing me, were singed on my behalf. From a legal perspective, do I need to redraw new lease contracts, null and void the old one and if so, How do I make the tenant re-sign the new ones? Is there any easy way to reassign the old contract in form of addendum or something similar?
