(a) Any notice of lien may be amended or credit extended as provided in section 271 of this title by an additional recording at any time during the 90-day period following recording of the notice of lien. An amendment which increases the amount of the claimed lien, or describes different or additional real estate or owners, is effective only from the time of recording of the amendment.
(b) An amendment does not extend the period of effectiveness of a recorded lien except as provided in subsection (a) of this section.
(c) An extension of credit extends the period of effectiveness of a recorded lien as provided in section 271 of this title.
(d) An amendment or notice of extension of credit shall set forth the recording office document location reference and date of recording of the notice of lien being amended or under which credit is being extended and shall state the respects in which the original notice of lien is being amended or that the recording is for the purpose of giving notice of extension of credit. If separate lots, parcels or tracts of real estate are being improved under a single notice of lien, the amendment or notice of extension of credit shall specify which lot, parcel or tract is being affected by the amendment or extension of credit; if the amendment or notice of extension of credit does not so specify, the presumption under section 255(b) of this title shall apply.
