The small-estate route and its cost
Oklahoma's simplified procedure is the affidavit for collection of personal property (58 O.S. § 393), for estates within $50,000. It is not filed with the court, so there is no court filing fee for the affidavit itself. Check the Oklahoma limit or see how long probate takes there.
What the court fee does not cover
The schedule above is only the court's own charge. Publishing notice to creditors in a newspaper, certified copies of letters, a fiduciary bond where the court requires one, appraisals and recording fees for real estate are billed separately by whoever provides them. Those notices also start Oklahoma's creditor claim period of 2 months (58 O.S. § 331), which usually decides how soon the estate can close. Most courts can waive or defer fees for a petitioner who cannot pay; the clerk's office has the request form.
