N.H. Rev. Stat. § 479-A:8
Subsequent to recording the declaration as provided in this chapter and while the property remains subject to this chapter, no lien shall thereafter arise or be effective against the property. During such period liens or encumbrances shall arise or be created only against each unit and the percentage of undivided interest in the common areas and facilities appurtenant to such unit in the same manner and under the same conditions in every respect as liens or encumbrances may arise or be created upon or against any other separate parcel of real property subject to individual ownership; provided that no labor performed or materials furnished with the consent or at the request of a unit owner or his agent or his contractor or subcontractor shall be the basis for the filing of a lien pursuant to the lien law against the unit or any other property of any other unit owner not expressly consenting to or requesting the same, except that such express consent shall be deemed to be given by the owner of any unit in the case of emergency repairs thereto. Labor performed or materials furnished for the common areas and facilities, if duly authorized by the association of unit owners, the manager or board of directors in accordance with this chapter, the declaration or bylaws, shall be deemed to be performed or furnished with the express consent of each unit owner and shall be the basis for the filing of a lien pursuant to the lien law against each of the units and shall be subject to the provisions of this section. In the event a lien against 2 or more units becomes effective, the unit owners of the separate units may remove their unit and the percentage of undivided interest in the common areas and facilities appurtenant to such unit from the lien by payment of the fractional or proportional amounts attributable to each of the units affected. Such individual payment shall be computed by reference to the percentages appearing on the declaration. Subsequent to any such payment, discharge or other satisfaction, the unit and the percentage of undivided interest in the common areas and facilities appurtenant thereto shall thereafter be free and clear of the lien so paid, satisfied or discharged. Such partial payment, satisfaction or discharge shall not prevent the lienor from proceeding to enforce his rights against any unit and the percentage of undivided interest in the common areas and facilities appurtenant thereto not so paid, satisfied or discharged.
