Oklahoma court costs
The statewide district-court flat fee for a probate case is $135.00 (28 O.S. § 152(A)(3)) plus permanent mandatory statewide surcharges: +$6 Law Library Fund (subsection B), +$25 Oklahoma Court Information System (subsection C), +$5 court-appointed special advocate/OCASA (subsection D), and +$2 miscellaneous (subsection E) — $173 total. A +$10 Court Clerk's Records Management and Preservation Fund surcharge (subsection G) applied only 'until November 1, 2023' in the cited Oklahoma State Senate edition (which raised the running total to $183 while in effect); the record before us does not show a later reauthorization. A separate $10 courthouse-security fee is county-optional (subsection F) and is excluded from the statewide figure.
$173 is the amount the statute states. Sources reviewed August 9, 2026. Latest primary-source re-fetch October 3, 2026.
Every line below is computed from the statutory schedule quoted at the end of this page. These are court charges only. They are not an estimate of the total cost of settling an estate.
| Charge | $25,000 estate | $100,000 estate | $400,000 estate | $1,000,000 estate |
|---|---|---|---|---|
| Probate and guardianship flat fee (28 O.S. s 152(A)(3)) | $135 | $135 | $135 | $135 |
| Law Library Fund (subsection B) | $6 | $6 | $6 | $6 |
| Oklahoma Court Information System Revolving Fund (subsection C) | $25 | $25 | $25 | $25 |
| Court-appointed special advocates, OCASA (subsection D) | $5 | $5 | $5 | $5 |
| Judicial Complaints and interpreter funds (subsection E) | $2 | $2 | $2 | $2 |
| Total from this schedule | $173 | $173 | $173 | $173 |
Every line is a permanent statewide charge the statute sets for a probate filing. A county may add the optional courthouse-security fee, and a specific case can carry further charges this section does not price.

Oklahoma’s $173 figure is not a single line. It is the sum of the separate charges below, each set by its own part of the Oklahoma fee provision. Every one is a permanent, statewide charge on opening this kind of case, which is why they combine into one number a filer can check rather than take on trust.
Added together, these come to $173 — the figure this page headlines. If any component changed in the source, the sum would no longer match, and the build withholds the total rather than publishing a number whose parts no longer add up.
These amounts appear in or beside the same Oklahoma schedule, so a reader can easily mistake one for part of the fee. Each is held out of the figure above for the specific reason given, which is the difference between an honest total and an inflated one.
The Oklahoma caveats are listed once, on the Oklahoma overview.
