When a deed near Dickinson says lot and block, look up the League City plat map it refers to. This League City guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
Tracking down the League City plat map

Pulling up a parcel
Property in and around La Marque are published on the Galveston County ArcGIS parcel map, free to use and open without a login.

Closer to Dickinson, the record panel usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
When there's no plat
Acreage around Santa Fe outside a subdivision may have no plat at all; look for a recorded survey for land there.
League City and the county around it
League City is part of Galveston County, Texas, so its parcels are on the county's map. For a parcel near Kemah, City or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the city limits out by Dickinson usually falls under county rules, not municipal ones.

Deeds, plats and who keeps them
