FAQ

Is Nassau County part of NYC ACRIS?

No. Nassau is a separate county and its Clerk maintains a separate recorded-document index. NYC ACRIS covers Bronx, Kings, New York, Queens and Richmond only.

Does this use the New York State UCC system?

No. Data comes from the Nassau County Clerk index, including county-recorded UCC filings, judgments and liens. The New York State Department of State UCC system is a different source.

Can I search by lender or secured party?

Yes. Use securedPartyNames. The actor filters results to the secured-party, plaintiff, grantee or mortgagee side.

Can I get only new liens without releases?

Yes. Set includeReleases: false. Release, satisfaction, discharge, termination, withdrawal and cancellation records are then skipped.

Can I look up one document number?

Yes. Use searchMode: "document" and documentNumbers. Prefix matches are rejected; only the exact number is returned.

Does the actor return document images?

No. It returns the public index detail, parties, amounts and property data. Images and certified copies are not downloaded or sold.

Is this an FCRA consumer report?

No. This is public-record research for business, lending, KYB and due-diligence workflows.
