Intestate only, $75,000, homestead excluded from the cap
Under Texas Estates Code Chapter 205, a small estate affidavit is available only when the decedent died without a will, and only when non-exempt probate assets — excluding the homestead and other exempt property — total $75,000 or less. If there's a valid will, this path isn't available at all; consider muniment of title instead.
The one real surprise: the affidavit can still convey the house
Filed with a court, unlike many states' versions
Unlike some states where the affidavit goes straight to a bank or DMV, Texas requires it to be filed with, and approved by, the county court with probate jurisdiction — typically costing $300-$400 in filing fees, though an attorney isn't usually needed.
A 30-day wait, built in on purpose
At least 30 days must pass since the date of death before filing, and no petition for the appointment of a personal representative can be pending or already granted — the legislature built in the wait specifically to allow a will to surface before the shortcut is used.
Statewide limit, no single statewide court
Harris, Dallas, Travis, and Bexar County among them — the affidavit is filed in whichever local court handles probate in the decedent's county, but the $75,000 threshold applies identically everywhere.
