If a lease also includes provisions for a sublease or assignment of lease, the notice of lien must be recorded not later than 180 days after the lessee takes possession of the leased premises. If the transferor personally serves written notice of the intended execution of the lease on the broker entitled to claim a lien at least 10 days prior to the date of the intended execution of the lease, the notice of lien must be recorded before the date indicated in such notice for the execution of the lease. The lien shall attach as of the recording of the notice of lien and shall not relate back to the date of the written instrument.
