NRS 105.040
Effective date of perfection or notice.
1.
The perfection or notice provided by a security instrument filed pursuant to NRS 105.030 is effective from the date of presentation for filing until the interest granted as security is released by the filing of a termination statement or a release or reconveyance of all or a part of the property signed by the secured party or trustee. No renewal, refiling or continuation statement is required to continue this effectiveness.2.
Perfection or notice provided by a security instrument covering real or personal property located in this state which was filed with the Secretary of State or recorded in the office of a county recorder before October 1, 1995, or which was filed or recorded before March 1, 1967, in compliance with the law in effect at the time of its filing or recordation, remains effective for the period provided by the law in effect at the time of its filing or recordation.3.
Such an instrument may be filed anew pursuant to NRS 105.030, and if so filed has the effect given to security instruments originally filed pursuant to NRS 105.010 to 105.080, inclusive. The priority of such a filing dates from the time that the security interest was first filed with the Secretary of State or recorded in the office of a county recorder and not from the date the instrument is filed anew pursuant to NRS 105.030.
