該術(shù)語（也稱為recording statutes)是指有關(guān)財產(chǎn)，尤指不動產(chǎn)權(quán)益的登記，由此而確立決定某人對該財產(chǎn)權(quán)利主張的次序先后標(biāo)準(zhǔn)的法規(guī)，其應(yīng)為“不動產(chǎn)登記法” [1]。此種立法的目 的主要是保護善意買主對抗先前未登記的權(quán)益主張。在美國，此種法規(guī)主要分為三種，即: notice statute、race statute以及 race-notice statute。它們的區(qū)別在于：notice statute為“不知情購買人優(yōu)先法”，指一種財產(chǎn)購置登記法規(guī)，規(guī)定凡購置之權(quán)益， 尤指不動產(chǎn)權(quán)益，以最近購買財產(chǎn)權(quán)益且不知道原先有人曾購置過此財產(chǎn)但未登記者具有對抗他人的優(yōu)先權(quán)的法規(guī)，也稱為 notice act 或 notice recording statute，在美國，約有一半的州實施該種法規(guī)[2]。race statute則為“登記順序優(yōu)先法”，指規(guī)定以登記先后決定優(yōu)先順序的法規(guī)，而不管登記時當(dāng)事人是否知悉先前有人曾購置過同一財產(chǎn)，這種法規(guī)類似我國的不動產(chǎn)登記法規(guī)，在美國也適用于適用大陸法的Louisiana州等，也被稱為 raceact[3]。race-notice statute為“不知情登記優(yōu)先法”，指不動產(chǎn)購置登記相關(guān)的法規(guī)，規(guī)定凡在不知道不動產(chǎn)已經(jīng)被購置但卻未登記的情況下購置不動產(chǎn)且登記者具有對抗原先購置者的優(yōu)先權(quán)，但預(yù)先知悉真情者除外，也稱為notice race statute [4]。

[2] “An unrecorded conveyance or other instrument is invalid as against a subsequent bona fide purchaser (creditor or mortgagee if the statute so provided) for value and without notice. Under this type of statute the subsequent bona fide purchaser prevails over the prior interest whether the subsequent purchaser records or not.” Cf.

[3] “A recording act providing that the person who records firet, regardless of notice, has priority. Only Louisiana and North Carolina have race statutes. ”

[4] “In some jurisdiction, in recording of documents of title to real estate, the first grantee or mortgagee to record in the chain of title without actual notice of a prior unrecorded deed or mortgage prevails. ”Cf.
