My office lease will be expired on July 9. I notified the manager that I did not intend to renew the lease. He told me to give him a 30 Days Notice to Vacate after July 9. But I don't want to pay for extra rent since I don't use the office anymore. Can I serve the notice right now? I guess that I still have to pay for the rent from July 10 to July 27 (30 days after June 28).I couldn't find any termination provision other than the sentence saying "The term shall be a 12 month basis commencing on July 10, 2009 and terminating on July 9, 2010 unless sooner terminated pursant to the provisions hereof." No Notice of Vacate was mentioned in the agreement either. Only in the HOLDING OVER section, it states that "if said Lessee holds possession of the said Premises after the term of this Lease, such Lessee shall become a tenant for successive terms of one month each upon the terms and rent herein specified, and shall continue to be tenant until such tenancy shall be terminated by Lessor or Lessee upon one month written notice prior to the date of termination of such tenancy." But I don't want to possess the office after the lease expires on July 9.Therefore this HOLDING OVER provision does not apply.
