Okla. Stat. tit. 22, § 22-1082: Court costs and expenses of representation

If the applicant is unable to pay court costs and expenses of

representation, he shall include an affidavit to that effect with

the application, which shall then be filed without costs. Counsel

necessary in representation shall be made available to the applicant

after filing the application on a finding by the court that such

assistance is necessary to provide a fair determination of

meritorious claims. If an attorney is appointed to represent such

an applicant then the fees and expenses of such attorney shall be

paid from the court fund.
