Here's the thing that surprises people: Texas does not publish statewide probate forms. Unlike California's fill-in-the-blank Judicial Council forms, Texas probate is document-driven, and county clerks generally don't provide forms or legal advice. The application, order, and letters are drafted — usually by an attorney — to fit each estate.
Why There Are No Standard Texas Forms
Texas treats representing an estate as practicing law, so most administrations require a licensed attorney, who prepares the documents. That's why you won't find an official “Texas probate form” packet the way California has one. What you file instead are tailored legal documents: an Application to Probate Will and for Issuance of Letters Testamentary (or an application for administration if there's no will), a proof of death and other facts, a proposed Order admitting the will, and the Oath — after which the clerk issues Letters Testamentary or Letters of Administration.
The Do-It-Yourself Exceptions
A few narrow Texas procedures have accessible forms and can sometimes be handled without an attorney:
Where Texas forms actually come from
For the limited do-it-yourself procedures, TexasLawHelp.org (a project of Texas Legal Services Center) publishes free guided forms. For a full administration, the documents are drafted for your case — there's no statewide packet to download.

Because there's no DIY form packet for a full administration, and Texas treats estate representation as practicing law, most people work with a probate attorney. Independent administration keeps costs down, and the fee usually comes from the estate.
