City Register

The City Register is the Department of Finance office that records property instruments — deeds, mortgages, satisfactions, declarations, UCC fixture filings — for four boroughs; Staten Island's records sit with the Richmond County Clerk instead. Every recorded instrument indexes against the affected lots, building the public chain of title parcel by parcel.

For analysis, the Register's records are the authoritative layer for ownership and encumbrance questions: who took title, under what instrument, what debt attaches, what agreements run with the land. Their publication lag — instruments surface weeks after closing — is the caveat every recency claim about ownership must carry.
