44A-20. Duties and liability of obligor.

(a) Upon receipt of the notice of claim of lien upon funds provided for in this Article, the obligor shall be under a duty to retain any funds subject to the lien or liens upon funds under this Article up to the total amount of such liens upon funds as to which notices of claims of lien upon funds have been received.

(b) If, after the receipt of the notice of claim of lien upon funds to the obligor, the obligor makes further payments to a contractor or subcontractor against whose interest the lien or liens upon funds are claimed, the lien upon funds shall continue upon the funds in the hands of the contractor or subcontractor who received the payment, and in addition the obligor shall be personally liable to the person or persons entitled to liens upon funds up to the amount of such wrongful payments, not exceeding the total claims with respect to which the notice of claim of lien upon funds was received prior to payment.

(c) If an obligor makes a payment after receipt of notice of claim of lien on funds and incurs personal liability under subsection (b) of this section, the obligor shall be entitled to reimbursement and indemnification from the party receiving such payment.

(d) If the obligor is an owner of the property being improved, the lien claimant shall be entitled to a claim of lien upon real property upon the interest of the obligor in the real property to the extent of the owner's personal liability under subsection (b) of this section, which claim of lien on real property shall be enforced only in the manner set forth in G.S. 44A-7 through G.S. 44A-16 and which claim of lien on real property shall be entitled to the same priorities and subject to the same filing requirements and periods of limitation applicable to the contractor. The claim of lien on real property is perfected as of the time set forth in G.S. 44A-10 upon satisfaction of those requirements set forth in G.S. 44A-11. A lien waiver signed by the contractor prior to a subcontractor's perfecting its claim of lien on real property in accordance with G.S. 44A-11 waives the subcontractor's right to enforce the contractor's claim of lien on real property, but does not affect the subcontractor's right to a claim of lien on funds or the subcontractor's right to a claim of lien on real property allowed under this subsection. The claim of lien on real property as provided under this subsection shall be in the form set out in G.S. 44A-12(c) and shall contain, in addition, a copy of the notice of claim of lien upon funds given pursuant to G.S. 44A-19 as an exhibit together with proof of service thereof by affidavit, and shall state the grounds the lien claimant has to believe that the obligor is personally liable for the debt under subsection (b) of this section.

(e) A notice of claim of lien upon funds under G.S. 44A-19 may be filed by the obligor with the clerk of superior court in each county where the real property upon which the filed notice of claim of lien upon funds is located for the purpose of discharging the notice of claim of lien upon funds by any of the methods described in G.S. 44A-16.

(f) A bond deposited under this section to discharge a filed notice of claim of lien upon funds shall be effective to discharge any claim of lien on real property filed by the same lien claimant pursuant to subsection (d) of this section or G.S. 44A-23 and shall further be effective to discharge any notices of claims of lien upon funds served by lower tier subcontractors or any claims of lien on real property filed by lower tier subcontractors pursuant to subsection (d) of this section or G.S. 44A-23 claiming through or against the contractor or higher tier subcontractors up to the amount of the bond.
