St. Louis County land records
Deeds and plats behind the St. Louis County map are kept by the county's recording office; the official St. Louis County website names which office that is. A deed book and page or instrument number on the county record is the fastest way to pull the document for a lot in Bellerive Acres.
Making sense of a St. Louis County parcel card
Entries in the county owner column aren't always a person: 'Estate of', 'et al' and 'c/o' entries near Bel-Nor each mean something different. Look at where the tax bill goes for land near Clayton: a bank or law office address near Lemay hints at a trust or an estate, worth noting well before you write. Records for land near Clayton reflect the assessor's last update, which means a deed filed this season may be missing.
