Katy straddles the corner where Waller, Harris and Fort Bend Counties come together, so the first question for many Katy families is which county their case belongs in. Fritz Law Firm, PLLC practices in all three, which means a Katy family law attorney at the firm can take the case on either side of the line.
A Katy home can be in Harris County, Fort Bend County or Waller County, and a Katy mailing address does not tell you which one. The City of Katy itself sits close to the point where the three counties touch, and most of Greater Katy is unincorporated land outside the city limits.
The county matters because each county runs its own courthouse, clerk and family courts. Two neighbors on the same Katy ISD bus route can live in different counties. The table below is a rough guide to how the lines fall; the property record for your address is what settles it.
| County | Parts of the Katy area generally in it | Where that county's family cases are heard |
|---|---|---|
| Harris County | Much of the unincorporated Katy area east and north of the City of Katy, plus part of the city itself | Harris County Civil Courthouse, 201 Caroline Street, downtown Houston |
| Fort Bend County | Much of Katy south of I-10, including most of Cinco Ranch, plus the City of Fulshear and its neighborhoods | Fort Bend County Justice Center, 1422 Eugene Heimann Circle, Richmond |
| Waller County | The western and northwestern edge of Katy, including the Cane Island area and neighborhoods toward Brookshire | Waller County Courthouse, 836 Austin Street, Hempstead |
The quickest way to check the county for a Katy address is the appraisal district property search. Every Texas county has an appraisal district that lists each parcel inside its borders, so the district that finds your address is the county your home sits in.
Knowing the county is the first step, not the last. The rules on where a family case may be filed, which depend on residence and on where the children live, are explained on the Areas We Serve page.
Katy ISD covers most of Greater Katy across all three counties, and its attendance lines ignore city and county boundaries. Fulshear is split between two districts: east Fulshear is generally zoned to Katy ISD, while west Fulshear is generally zoned to Lamar Consolidated ISD.
Some large Fulshear-area communities, such as Cross Creek Ranch and Firethorne, contain homes zoned to each district. A few addresses on the Waller County edge near Brookshire fall in Royal ISD. Because a Katy-area move can change a child's district without changing the mailing city, parents should look up the campus for any new address before agreeing to it.
Katy began as a rice-farming town on the Missouri-Kansas-Texas (MKT) railroad, the line most accounts credit for the town's name. William Eule brought rice farming to the area in 1901, and the concrete rice dryers built in 1944 still stand near downtown as a landmark.
That history is kept at Katy Heritage Park on George Bush Drive and at the restored MKT depot on First Street, and the city's Rice Harvest Festival fills downtown each October. The newer Katy grew along the Katy Freeway (I-10), the Grand Parkway (State Highway 99) and the Westpark Tollway, with Katy Mills mall drawing shoppers from all three counties.
Fulshear, west of Katy along FM 1093 and FM 359, has added residents faster than almost any other Texas city since the 2020 Census; Census Bureau estimates ranked it second among U.S. cities of 20,000 or more for growth from 2024 to 2025. The Westpark Tollway has been extended west along FM 1093 into Fulshear, with the first section opening in February 2026. For co-parents, the practical effect is simple: two homes a short drive apart can sit in different counties and different school districts.
Whichever county your Katy home is in, the Texas law is the same. These pages explain it.
That depends on the county your home is in, not the mailing address. Katy addresses fall in Harris, Fort Bend or Waller County, whose family courts sit in downtown Houston, Richmond and Hempstead. Look the address up on the appraisal district site, then call the firm to talk through the rest.
No. One Texas law license is good in every county in the state. Jessica Fritz has been licensed since 2008 and practices in Montgomery County, where the office is, as well as Fort Bend, Harris and Waller.
Split-county couples are common in Katy, since the county lines run straight through the area. Where the case belongs depends on the filing rules described on the Areas We Serve page and on where any children have lived. Jessica Fritz reviews those facts at the first appointment.
No. Fulshear is its own city in Fort Bend County, west of Katy, so Fulshear family cases go to Fort Bend County. Fulshear children may attend Katy ISD or Lamar Consolidated ISD depending on the subdivision.
From the City of Katy, Richmond's Fort Bend County Justice Center is about 18 miles away, Hempstead's Waller County Courthouse is about 40 miles away, and downtown Houston is about 30 miles east on I-10. Plan for traffic on I-10 and the Grand Parkway on hearing days.
