(a) The Child Support Enforcement Division (CSED) sends a notice required by Section 237A of Title 56 of the Oklahoma Statutes to noncustodial parents and custodial persons in IV-D cases at least once every 12 months, unless the amount of past due support has been determined in a court proceeding within the past twelve months.  [56 O.S. § 237A]  CSED refers to this notice as a Notice and Order of Child Support Lien or annual notice. The annual notice confirms the amount of past support and establishes a payment plan to collect past support. It may establish an address of record for noncustodial parents and custodial persons, and it includes notice of the procedure to submit address changes to the Central Case Registry. The annual notice:

• (1) informs the noncustodial parent that child support services under the state plan are being provided;
• (2) instructs the noncustodial parent to redirect the support payments to the Centralized Support Registry; and
• (3) advises the noncustodial parent of the amount of past support and collection actions that may be taken to collect the support debt.  

(b) The annual notice includes directions for the noncustodial parent to make specified monthly payments to satisfy past-due support.  Under Section 137 of Title 43 of the Oklahoma Statutes, the past-due support repayment schedule may not exceed three years unless specific findings of fact supporting the action are made.  CSED compares the monthly payment amount based on this three-year repayment schedule with 50 percent of the current monthly support obligation and sets the amount of the monthly payment included in the annual notice at the greater of these two amounts.

(c) The initial notice is served upon the noncustodial parent as provided in Section 2005 of Title 12 of the Oklahoma Statutes.  If there is an address of record on file with the Central Case Registry under Section 112A of Title 43 of the Oklahoma Statutes, the notice may be served by regular mail at the address on record.  Subsequent notices may be served by regular mail with a certificate of mailing to the last address of record.  The initial notice and subsequent annual notices are sent to the custodial person by regular mail with a certificate of mailing.

(d) The annual notice sent to the noncustodial parent must not include the custodial person's address or employer's name and address.  The annual notice sent to the custodial person must not include the noncustodial parent's address or employer's name and address.

(e) The noncustodial parent or custodial person may timely request in writing an administrative review of the annual notice under Section 237A of Title 56 of the Oklahoma Statutes.
