How probate costs work in Oklahoma

Probate in Oklahoma runs through the District Court in the county where the person lived — Oklahoma County (Oklahoma City), Tulsa, Cleveland, Canadian, Comanche and the state's 77 counties. Oklahoma sets the executor commission by a statutory sliding scale whose low breakpoints make it behave like a near-flat 2.5%, and it has no estate or inheritance tax — one of the more tax-friendly states for settling an estate.

1. Executor commission — statutory scale

58 O.S. § 527(A): the commission is 5% of the first $1,000, 4% of the next $5,000, and 2.5% of everything above $6,000 of the estate accounted for. Because the breakpoints are low, it's effectively a flat ~2.5% for estates of any real size. It's mandatory — the court must allow it when the will is silent.

On a $500,000 estate that's $12,600. Co-executors share a single fee. Family members serving as executor often waive the commission, since it's taxable income while an inheritance is not.

2. Attorney fees — often the same schedule

Oklahoma attorney fees are not fixed by statute, but in practice attorneys frequently mirror the 5/4/2.5% executor schedule or bill hourly, all subject to court approval. On a $500,000 estate a statutory-scale fee is about $12,600. It's a separate cost from the commission.

3. Court & other costs

Filing fee — about $200 to open probate (e.g. ~$204 in Oklahoma County).
Publication to creditors — newspaper notice, ~$100–$150.
Bond — may be required unless waived by the will or heirs.
Appraisal, certified copies — small additional costs.

4. No Oklahoma death tax

No state estate or inheritance tax: Oklahoma repealed its estate tax effective 2010, and has no inheritance tax. Only the federal estate tax can apply, to estates above $15M (2026) — so nearly all Oklahoma estates owe no death tax.

5. When probate can be simplified in Oklahoma

Small estate affidavit (58 O.S. § 393) — personal property of $50,000 or less, no real estate, 30 days after death.
Summary administration — estates up to $200,000, or when the decedent has been dead more than 5 years; a streamlined court process.
Living trust, joint tenancy, POD/TOD — bypass probate entirely.

Oklahoma probate cost — frequently asked questions

How much does probate cost in Oklahoma City / Tulsa?

The commission scale and the no-death-tax rule are statewide; only the county District Court differs. In Oklahoma County (Oklahoma City), Tulsa, Cleveland or Canadian, a $500,000 estate has a $12,600 statutory executor commission (often waived by family), a similar statutory-scale attorney fee, and about $200 in filing fees. Oklahoma has no estate or inheritance tax, so there's no death-tax layer on top.

Is the executor commission automatic in Oklahoma?

Yes — it's mandatory statutory compensation under 58 O.S. 527(A), which the court must allow when the will is silent, not a discretionary maximum a court can undercut. It's 5% of the first $1,000, 4% of the next $5,000, and 2.5% above $6,000. Family executors who are also heirs frequently waive it, since it's taxable income.

What is Oklahoma summary administration?

A streamlined court process for estates worth $200,000 or less, or when the decedent has been dead more than 5 years. It compresses the notice and hearing steps, so it's faster and cheaper than full probate. For personal property under $50,000 with no real estate, the small estate affidavit is simpler still.

Does Oklahoma have an estate or inheritance tax?

No. Oklahoma repealed its estate tax effective 2010 and has never had a modern inheritance tax. Only the federal estate tax applies, and only to estates above the federal exemption ($15 million in 2026), so almost all Oklahoma estates owe no death tax.
