(a) Security interest—(1) In general. The term “security interest” means any interest in property acquired by contract for the purpose of securing payment or performance of an obligation or indemnifying against loss or liability. A security interest exists at any time—
(i) If, at such time, the property is in existence and the interest has become protected under local law against a subsequent judgment lien (as provided in subparagraph (2) of this paragraph (a)) arising out of an unsecured obligation; and
(ii) To the extent that, at such time, the holder has parted with money or money's worth (as defined in subparagraph (3) of this paragraph (a)).
For purposes of this subparagraph, a contract right (as defined in paragraph (c)(2)(i) of §301.6323(c)-1) is in existence when the contract is made. An account receivable (as defined in paragraph (c)(2)(ii) of §301.6323(c)-1) is in existence when, and to the extent, a right to payment is earned by performance.
A security interest must be in existence, within the meaning of this paragraph, at the time as of which its priority against a tax lien is determined. For example, to be afforded priority under the provisions of paragraph (a) of §301.6323(a)-1 a security interest must be in existence within the meaning of this paragraph before a notice of lien is filed.
(2) Protection against a subsequent judgment lien.
(i) For purposes of this paragraph, a security interest is deemed to be protected against a subsequent judgment lien on—
(A) The date on which all actions required under local law to establish the priority of a security interest against a judgment lien have been taken, or
(B) If later, the date on which all required actions are deemed effective, under local law, to establish the priority of the security interest against a judgment lien.
For purposes of this subdivision, the dates described in (A) and (B) of this subdivision (i) shall be determined without regard to any rule or principle of local law which permits the relation back of any requisite action to a date earlier than the date on which the action is actually performed. For purposes of this paragraph, a judgment lien is a lien held by a judgment lien creditor as defined in paragraph (g) of this section.
(ii) The following example illustrates the application of paragraph (a)(2):
(ii) Because the security interest is perfected during the 20-day period against a subsequent judgment lien arising out of an unsecured obligation, and because filing or the taking of possession before the conclusion of the period of temporary perfection is not considered, for purposes of paragraph (a)(2)(i) of this section, to be a requisite action which relates back to the beginning of such period, the requirements of this paragraph are satisfied. Because filing or taking possession is a condition precedent to continued perfection, filing or taking possession of the collateral is a requisite action to establish such priority after expiration of the period of temporary perfection. If there is a lapse of perfection for failure to file or take possession, the determination of when the security interest exists (for purposes of protection against the tax lien) is made without regard to the period of temporary perfection.
(3) Money or money's worth. For purposes of this paragraph, the term money or money's worth includes money, a security (as defined in paragraph (d) of this section), tangible or intangible property, services, and other consideration reducible to a money value. Money or money's worth also includes any consideration which otherwise would constitute money or money's worth under the preceding sentence which was parted with before the security interest would otherwise exist if, under local law, past consideration is sufficient to support an agreement giving rise to a security interest, and provided that the grant of the security interest is not a fraudulent transfer under local law or 28 U.S.C. §3304(a)(2). A firm commitment to part with money, a security, tangible or intangible property, services, or other consideration reducible to a money value does not, in itself, constitute a consideration in money or money's worth. A relinquishing or promised relinquishment of dower, curtesy, or of a statutory estate created in lieu of dower or curtesy, or of other marital rights is not a consideration in money or money's worth. Nor is love and affection, promise of marriage, or any other consideration not reducible to a money value a consideration in money or money's worth.
(4) Holder of a security interest. For purposes of this paragraph, the holder of a security interest is the person in whose favor there is a security interest. For provisions relating to the treatment of a purchaser of commercial financing security as a holder of a security interest, see §301.6323(c)-1(e).
(b) Mechanic's lienor—(1) In general. The term “mechanic's lienor” means any person who under local law has a lien on real property (or on the proceeds of a contract relating to real property) for services, labor, or materials furnished in connection with the construction or improvement (including demolition) of the property. A mechanic's lienor is treated as having a lien on the later of—
(i) The date on which the mechanic's lien first becomes valid under local law against subsequent purchasers of the real property without actual notice, or
(ii) The date on which the mechanic's lienor begins to furnish the services, labor, or materials.
(2) Example. The provisions of this paragraph may be illustrated by the following example:
(c) Motor vehicle.
(1) The term “motor vehicle” means a self-propelled vehicle which is registered for highway use under the laws of any State, the District of Columbia, or a foreign country.
(2) A motor vehicle is “registered for highway use” at the time of a sale if immediately prior to the sale it is so registered under the laws of any State, the District of Columbia, or a foreign country. Where immediately prior to the sale of a motor vehicle by a dealer, the dealer is permitted under local law to operate it under a dealer's tag, license, or permit issued to him, the motor vehicle is considered to be registered for highway use in the name of the dealer at the time of the sale.
(d) Security. The term “security” means any bond, debenture, note, or certificate or other evidence of indebtedness, issued by a corporation or a government or political subdivision thereof, with interest coupons or in registered form, share of stock, voting trust certificate, or any certificate of interest or participation in, certificate of deposit or receipt for, temporary or interim certificate for, or warrant or right to subscribe to or purchase, any of the foregoing; negotiable instrument; or money.
(e) Tax lien filing. The term “tax lien filing” means the filing of notice of the lien imposed by section 6321 in accordance with §301.6323(f)-1.
(f) Purchaser—(1) In general. The term “purchaser” means a person who, for adequate and full consideration in money or money's worth (as defined in subparagraph (3) of this paragraph (f)), acquires an interest (other than a lien or security interest) in property which is valid under local law against subsequent purchasers without actual notice.
(2) Interest in property. For purposes of this paragraph, each of the following interest is treated as an interest in property, if it is not a lien or security interest:
(i) A lease of property,
(ii) A written executory contract to purchase or lease property,
(iii) An option to purchase or lease property and any interest therein, or
(iv) An option to renew or extend a lease of property.
(3) Adequate and full consideration in money or money's worth. For purposes of this paragraph, the term “adequate and full consideration in money or money's worth” means a consideration in money or money's worth having a reasonable relationship to the true value of the interest in property acquired. See paragraph (a)(3) of this section for definition of the term “money or money's worth.” Adequate and full consideration in money or money's worth may include the consideration in a bona fide bargain purchase. The term also includes the consideration in a transaction in which the purchaser has not completed performance of his obligation, such as the consideration in an installment purchase contract, even though the purchaser has not completed the installment payments.
(4) Examples. The provisions of this paragraph may be illustrated by the following examples:
(g) Judgment lien creditor. The term “judgment lien creditor” means a person who has obtained a valid judgment, in a court of record and of competent jurisdiction, for the recovery of specifically designated property or for a certain sum of money. In the case of a judgment for the recovery of a certain sum of money, a judgment lien creditor is a person who has perfected a lien under the judgment on the property involved. A judgment lien is not perfected until the identity of the lienor, the property subject to the lien, and the amount of the lien are established. Accordingly, a judgment lien does not include an attachment or garnishment lien until the lien has ripened into judgment, even though under local law the lien of the judgment relates back to an earlier date. If recording or docketing is necessary under local law before a judgment becomes effective against third parties acquiring liens on real property, a judgment lien under such local law is not perfected with respect to real property until the time of such recordation or docketing. If under local law levy or seizure is necessary before a judgment lien becomes effective against third parties acquiring liens on personal property, then a judgment lien under such local law is not perfected until levy or seizure of the personal property involved. The term “judgment” does not include the determination of a quasi-judicial body or of an individual acting in a quasi-judicial capacity such as the action of State taxing authorities.
(h) Effective/applicability date. This section applies as of April 4, 2011.
