I signed a 12 mon lease terminating 09/28/09. It has 60-day notice clause. Gave notice 08/28/09. Do I have to pay thru 10/28

-Assuming this is a residential lease, the answer will probably be controlled by Ca. Civil Code, Sec. 1945.5. This section requires automatic renewal provisions and provisions requiring notice of non-renewal in printed leases to be in at least eight-point boldfaced type, together with a similar-sized warning just above the signature blocks . If the lease complies, you probably would be liable for rent through 10/27 (60 days from 8/28), unless the lessor is able to re-rent the unit before then.
-If the lease does not comply with Civ 1945.5, then you would probably be liable only through 9/28.
-As always, these answers are general statements. The exact outcome would depend on all of the facts of your case.
