UCC financing statement

A UCC financing statement perfects a security interest in personal property. Real estate meets it twice: fixture filings, recorded where equipment attached to realty secures debt, and — distinctively in New York — cooperative apartments, where the 'real estate loan' is legally a loan against shares and proprietary lease, secured by a UCC filing rather than a mortgage.

That co-op wrinkle matters for records work: a co-op unit's financing history lives in UCC filings, not the mortgage indexes, and searches that only read mortgages miss it entirely. UCC filings also lapse on statutory schedules unless continued, so their status and continuation trail carries the same open-or-stale reading as other liens.
