SAN MARCOS — HAYS COUNTY'S LEGAL HUB
The Hays County Courthouse at 110 E. San Antonio Street in San Marcos is where all Hays County criminal and family law cases are heard — serving not just San Marcos, but also Kyle, Buda, Wimberley, Dripping Springs, and surrounding communities. The co-location of Texas State University creates a unique legal environment: elevated DWI and drug charges among the student population, Title IX matters, and a high volume of landlord-tenant disputes.
I-35 through San Marcos is among the most dangerous in Texas. The San Marcos stretch of I-35 — which also carries US-35 truck route traffic — sees some of the highest accident and fatality rates in the entire state, particularly around the Aquarena Springs and Wonder World Drive interchanges. Serious truck accident and wrongful death cases arise regularly on this corridor.
