Katy sits across Harris, Fort Bend, and Waller counties, so which court hears a probate case depends on exactly where the property sits, not the Katy mailing address.

TL;DR:

If you're settling an estate that includes a home in Katy, TX, the county matters more than the ZIP code. Katy spans Harris, Fort Bend, and Waller counties, and each handles probate differently. Katie Curran and Mario Djordjilov of MKAT Group at Keller Williams Signature work with executors and heirs across all three, and getting the venue right early avoids weeks of delay later.

Katie Curran, REALTOR® and co-founder of MKAT Group at Keller Williams Signature, works with families selling inherited property across Katy, TX, Fort Bend County, Harris County, Waller County, and the greater Houston area. This guide covers where probate cases involving Katy property actually get heard, and why the answer isn't as simple as "Katy."

What Is Probate Venue in Katy, TX?

Probate venue means which county's court has authority to hear a case. It's usually based on where the deceased person lived, but for real estate, the county where the property sits can also matter. Because Katy's boundary crosses three counties, two houses a few miles apart in "Katy" can end up in front of completely different courts.

Why Does Katy Span Three Counties?

Katy is a city, not a county, and its limits and extraterritorial jurisdiction cut across Harris County to the east, Fort Bend County to the south, and Waller County to the northwest. A Cinco Ranch address and a Cane Island address can both say "Katy, TX 77494" while sitting in different counties entirely.

Does my mailing address tell me which county handles probate?

No. Katy ZIP codes don't map cleanly to county lines. The property's actual county — which you can confirm through the county appraisal district or your title company — is what determines venue, not the city name on the mailbox.

Which Court Hears Probate Cases in Each County?

This is where it gets specific, and where a general practice agent without probate experience tends to guess wrong.

Harris County runs four dedicated statutory probate courts — Probate Court No. 1 through No. 4 — that handle nothing but probate, guardianship, and mental health matters. According to the Texas Government Code's statutory probate court provisions, Harris County's four probate courts split incoming cases by set percentages, so a Harris County filing lands with a judge who does this work full time.

Fort Bend County has no statutory probate court. Instead, probate is heard through the County Courts at Law, primarily Court No. 3 and Court No. 5, seated at the Fort Bend County Justice Center in Richmond. According to Fort Bend County's own court records, uncontested probate matters are typically heard virtually through County Court at Law No. 3.

Waller County has no statutory probate court either. Under the Texas Estates Code, in a county without a statutory probate court or a county court at law exercising probate jurisdiction, the constitutional county court hears probate cases directly — which is the structure Waller County appears to follow.

What's the difference between a statutory probate court and a county court at law?

A statutory probate court hears only probate, guardianship, and mental health cases, with a judge who specializes in that docket. A county court at law handles probate alongside civil, criminal, and other matters. Neither is "better" for a routine, uncontested case, but a statutory court's familiarity can matter more once a case gets contested.

How do I find out which county my inherited property is actually in?

The county appraisal district website for the property's address will show it directly, and your title company can confirm it during a preliminary title search before you file anything.

How Do You Determine Which Court Applies Before You File?

Most heirs find this out through a combination of their probate attorney and their own research into the property's county, not from any single centralized source. Sitting down early to work through the probate timeline with MKAT Group is often what keeps that step from turning into a bottleneck later.

I've had this come up directly with a Katy seller recently — we were able to confirm the county quickly, which let the family know which direction to head before they filed anything.

Who actually determines which court has jurisdiction — the family or the court itself?

The family (through their attorney, if they have one) identifies the correct county and files there. The court doesn't reach out and tell you where to file. Getting it wrong means a refiling delay, which is exactly the kind of early misstep that costs time no one budgeted for.

Does getting the venue wrong slow down the whole probate process?

It can, but the bigger timeline driver is usually where the estate is in the process, not the county. If nothing has been filed yet, the process can take several months. If a will exists and the case is already moving, probate is often complete in a matter of weeks, and it doesn't have to hold up a sale.

How Does Katy Compare to Richmond, TX?

Richmond sits entirely within Fort Bend County, so every probate case tied to a Richmond property goes through the same county court system, heard at the Fort Bend County Justice Center. There's no jurisdiction question to answer first.

Katy doesn't have that simplicity. A property a few streets over can fall under Harris County's statutory probate courts, Fort Bend County's Courts at Law, or Waller County's county court, depending on the exact parcel. Richmond sellers skip a step Katy sellers can't: figuring out which court has the case before anything else can move forward.

Why Does This Matter for Sellers in Katy, TX?

Filing in the wrong county doesn't just create paperwork. It delays the point at which an executor has legal authority to sell the property, which pushes back everything downstream: repairs, listing, closing. For a family already managing a loss, an avoidable procedural delay is the last thing that helps. Confirming the county before filing is a small step that protects the timeline for everything that follows.

What Am I Seeing in the Katy, TX Market Right Now?

Most of the heirs I work with assume probate has to be fully finished before a home can even go on the market. That's not accurate. If there's a will and the process has started, the probate side and the selling side can often run in parallel, and doing both at once is usually what gets a family to closing fastest. A lot of the delay I see isn't the court system — it's families waiting to start the sale process because they think they have to wait on probate first.

Who Is This Probate Guide For in Katy, TX?

Settling an estate that includes a Katy-area home and unsure which county has the case
Acting as executor for the first time and wanting to understand the filing process before contacting an attorney
Heirs who disagree on next steps and need a clear picture of the legal timeline before deciding anything
Selling an inherited property and trying to understand how the probate timeline affects when the home can actually list

Can you sell a home before probate is fully complete?

Often, yes, particularly with independent administration and a valid will. The probate process and the sale process can frequently move at the same time rather than one waiting on the other — worth confirming with your attorney based on your specific estate.
