Educational guide — not legal advice. Laws and figures change; confirm current details with a licensed Oklahoma attorney before relying on them.
The short answer
Oklahoma does not set probate fees by statute. Costs depend on the attorney’s billing arrangement, the type of administration, and the size and complexity of the estate. Here’s what to expect, and the ways many families avoid full probate entirely.
Attorney fees
Not fixed by a statutory percentage. Oklahoma attorneys charge a reasonable fee, typically hourly (often ~$200–$350/hr) or a flat fee, subject to court approval. Plan on roughly $2,500–$5,000+ for an uncomplicated estate.
Executor / personal representative fees
Set by statute under 58 O.S. §527: 5% of the first $1,000, 4% of the next $5,000, and 2.5% of all sums above $6,000 of the estate accounted for. The court may allow additional compensation for extraordinary services, capped at the amount of the statutory commission. The same schedule applies to administrators.
What the fee is based on
The §527 commission is figured on the whole estate accounted for (excluding property not ranked as assets) — effectively the probate estate the personal representative administers.
Court filing fees
Roughly $200 to file the probate petition (about $204 in many counties), plus newspaper publication of notice (commonly $100–$200).

How long probate takes in Oklahoma
About 6 to 12 months for a routine supervised probate. Summary administration for estates under $150,000 can finish in roughly 2 to 4 months. Contested estates, missing heirs, or real estate sales can extend that.
How to skip full probate (or shrink the bill)
- Small-estate procedure. $50,000 for the small-estate affidavit to collect personal property under 58 O.S. §393 (fair market value of Oklahoma property, less liens and encumbrances). Separately, estates under $150,000 qualify for faster summary administration under 58 O.S. §241.
- Real-property shortcut. Estates valued under $150,000 may use summary administration under 58 O.S. §241, which compresses notice and hearing steps and can settle real property far faster than full probate.
- A funded living trust. Assets in a properly funded revocable living trust skip probate entirely. The successor trustee distributes them privately, usually in a month or two.
- Beneficiary designations and joint ownership. Life insurance, retirement accounts, payable-on-death (POD) accounts, and jointly held property pass directly to the named person and never enter probate.
- Family member as executor. When a relative serves as executor, they can often waive the commission — meaningfully cutting the total bill.
Do you need a lawyer?
For most Oklahoma estates that go through full probate, yes — the court process has formal requirements and missed deadlines can cost more than the legal fees they were meant to avoid. For genuinely simple estates, or where a small-estate procedure applies, many families handle it themselves or use a legal document preparer for a flat fee.
The honest takeaway
The cheapest probate cost is the one you avoid in advance — by titling assets correctly, keeping beneficiary designations current, and, where it makes sense, using a living trust. If your estate is likely to exceed Oklahoma’s small-estate thresholds, it’s worth talking to a licensed Oklahoma estate attorney while you still have the option to plan.
