How to protect myself when moving in to existing lease?
I'm taking over for a friend's space in his apartment when his current lease ends. My understanding is that they are renewing the same terms as the old lease. I have already filled out and signed a "change of renter" form, or whatever it was called, in which I gave all my personal info for a background check etc. and noted under "security deposit" that it was my belief that it would be transferred from the previous tenant (which is what he told me). I have read the old lease, but the document I signed didn't come with a new lease, if in fact it's changed.
My question: What do I need to do/be aware of? I'm pretty clear, having read some posts in this forum, on what I would need to do when signing a new lease (how to document the condition of the place for the security deposit, etc.) Do I need to get notice of transfer of security deposit in writing? I assume the security deposit is one of those "jointly and severally" things -- how does that affect me, since the other occupants are staying on?
What else do I need to be aware of / get in writing / document?
Thanks very much.
