How much does it cost to file for custody in oklahoma?

This amount that a custody case could actually cost varies from case to case. If you pay an attorney, your legal fees could depend on things like the amount of conflict between the parties and how much your lawyer charges. In addition, there are court costs, such as filing fees and possibly for giving the documents to the other parent. If you are unable to pay the costs, you can request that an affidavit (known as an affidavit in forma pauperis or affidavit of a poor person) be filed informing the judge that you are a low-income person and asking the judge not to force you to pay court costs, 1 It will be the judge who decides whether to waive the court costs or not.
