(a) A real estate broker shall have a lien, in the amount of the compensation agreed upon by and between the broker and his or her client, upon commercial real estate or any interest therein which is subject to and described in the brokerage agreement and owned by a client or by a party whose commercial real estate may be liened if different from the client who has received written notice from the broker in conformity with subsection (f) prior to obtaining an interest in the commercial real estate through a purchase, lease, or conveyance. Commercial real estate, or an interest therein, acquired by a person other than a client prior to receipt of the notice from the broker required by this division is not subject to the lien provided by this division. The lien shall arise:
(1) Upon the satisfaction of each of:
a. Conveyance of the commercial real estate identified in and subject to the listing agreement, brokerage, or agency agreement for the sale or lease of commercial real estate as evidenced by a writing signed by the owner of the commercial real estate or the owner's expressly authorized agent;
b. With written notice, by certified mail, return receipt requested to the party whose commercial real estate may be liened, if different from the parties to the agreement; and
c. The satisfaction of all conditions in the agreement for payment of compensation.
(2) Upon conveyance of the commercial real estate identified in and subject to the agreement, when a broker having a written agreement with a prospective buyer or tenant to represent the buyer or tenant as to the purchase, lease, or other conveyance of commercial real estate becomes entitled to compensation; provided that the broker shall have given written notice, by certified mail, return receipt requested, to the party whose property may be liened, if different from the parties to the agreement.
(b) A lien provided herein shall attach to the commercial real estate, or any interest in commercial real estate as described in subsection (a), upon the broker's recording a notice of lien in the office of the judge of probate in the county in which the commercial real estate or interest in the commercial real estate is located.
(c) When payment to a broker is due in one lump sum and not paid, the notice of lien shall be recorded within 90 days after the tenant takes possession of the leased premises or the property or interest therein is conveyed.
(d) When payment to a broker is due in installments, all or a portion of which is due only after a conveyance of the commercial real estate, any notice of lien for those payments due after conveyance may be recorded at any time subsequent to the conveyance so long as the claim for lien is recorded within 90 days of the date the payment was due and not paid.
(e) If a broker has a written agreement with a client as provided for in subdivision (2) of subsection (a), the lien shall attach to the client's interest upon the client's purchasing, leasing, or otherwise accepting a conveyance of the commercial real estate and the recording of a notice of lien by the broker in the office of the judge of probate in the county in which the commercial real estate or interest in the commercial real estate is located, within 90 days after the later of purchase, lease, or other conveyance to the buyer or tenant or the failure of the buyer or tenant to compensate the broker or cause the broker to be compensated pursuant to its agreement.
(f) The lien notice shall state the name and address of the lien claimant, the name of the owner, a legally sufficient description of the commercial real estate upon which the lien is being claimed, and the amount for which the lien is claimed. The notice of lien shall contain a sworn statement that the information contained in the notice is true and accurate to the knowledge of the signatory. The lien notice shall recite that the broker has disclosed to all parties that a lien might be claimed under this division. The notice of lien shall be signed by the broker or by a person expressly authorized to sign on behalf of the broker and shall be verified before a notary public or other authorized officer.
(g) The broker shall mail a copy of the notice of lien to the owner of the commercial real estate by certified mail, return receipt requested. The broker's lien shall be void and unenforceable if notice is not given or if recording does not occur within the time and manner required by this division.
(h) (1) A broker may bring suit to enforce a lien in the circuit court in the county where the commercial real estate is located by filing a verified complaint and sworn affidavit that the notice of lien has been recorded in compliance with this division. Within 180 days after recording the notice of lien, the broker claiming a lien shall commence proceedings by filing a complaint. Failure to commence proceedings within 180 days after recording the notice of lien shall extinguish the lien.
(2) No subsequent notice of lien may be given for the same claim nor may that notice be asserted in any proceedings under this section.
(3) A complaint under this subsection shall contain a brief statement of the contract or agreement on which the lien is founded, the date when the contract or agreement was made, a description of the services performed, the amount due and unpaid, a legally sufficient description of the commercial real estate that is subject to the lien, and other facts necessary to state a claim for the payment of a commission, fee, or other compensation due the broker. The plaintiff shall make all interested parties, whose interest in the commercial real estate is affected by the action, defendants to the action, and shall issue summons and provide service as in other civil actions. The summons and complaint, and all other particulars of suit, shall be made in accordance with the Alabama Rules of Civil Procedure. All liens claimed under this section shall be foreclosed as provided for by law.
