When a listing near Velma mentions a lot number, you'll need the Duncan plat map to make sense of it. What this Duncan guide covers: where to request a copy, plat versus tax map, and the details that matter to buyers.
The Duncan plat map: start here
For a lot in Duncan, look for the plat book reference on the parcel record; use it to request a copy.
Pulling up a parcel
Begin with the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer; it includes each tax parcel from Central High to Marlow. With a lot near Empire City, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Velma, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements for land near Comanche are kept by the County Clerk. Long-held tracts around Marlow can trace back through a long string of deeds, and a title company earns its fee if money is changing hands.
Amended plats
An amended plat may change lots around Empire City, search the index for replats of the same subdivision; street vacations near Marlow show up in the records too.
Legal descriptions in Oklahoma
Oklahoma uses the Public Land Survey System, which means a tract near Comanche is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Empire City vary in size. Keep the legal description for land near Empire City when you talk to a surveyor.
What the map can't tell you
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near Marlow may sit a few yards off the line on screen. If you're looking near Velma, records update in batches, so a deed recorded last month can take weeks to appear.
Places you'll see on the map
Duncan holds the county offices, where most land records are kept. You'll also find Empire City, Comanche, Marlow, and Central High. Roughly 44,014 people call Stephens County home (Census estimate, 2023) spread over some 870 square miles. Stephens County was organized in 1907, which matters when you trace an old farm's title. Landmarks such as Waurika Lake help you orient on the aerial around Comanche.
Duncan and the county around it
Duncan lies within Stephens County, Oklahoma, so its parcels are on the county's map. Duncan is also the county seat, so deeds and plats are filed in town. For a home near Comanche, City or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits near Marlow generally follows county rules rather than the town's.
Land on the county line
