Around Roma, a rural legal description will cite an original survey and abstract; match it to the lines on the map. A survey is the only document that settles where a Starr County boundary actually runs.
Where Starr County deeds and plats are kept
The appraisal district handles assessments, while recorded deeds and plats for Starr County are kept by the county's land records office.
