In general, income withholding is the court ordered or administratively ordered deduction
                  of a specified amount from the obligor's income for payment of child support to the
                  obligee. Generally, at the time a court issues a child support order, the court will
                  also issue a separate income withholding order that is to be served on an obligor's
                  payor or employer, such as SSA, to deduct this amount from the obligor's income. Below
                  is each state's respective laws governing the service of process of income withholding
                  orders and who may serve the orders on SSA as the payor or employer.
               
               Arkansas: At the time of issuance of a child support order approving an immediate order of income
                  withholding, the court, Arkansas Office of Child Support Enforcement (OCSE), custodial
                  parent, noncustodial parent, or a representative of the custodial or noncustodial
                  parent may serve the order of income withholding upon the payor by first class mail.
                  Ark. Code Ann. § 9-14-222; OCSE, Enforcement Case Services vs. Payment Processing
                  Case Services, http://www.dfa.arkansas.gov/offices/childSupport/newToOCSE/Pages/compareServices.aspx (last accessed Apr. 29, 2011). If the payor does not properly remit the withholding,
                  the serving party will send a second notice to the payor pursuant to Rule 4 of the
                  Arkansas Rules of Civil Procedure. Id. The Arkansas Rules of Civil Procedure generally
                  permit service by personal delivery, registered mail, or certified mail. Ark. R. Civ.
                  P. 4. Service on the payor may be made by: (1) a sheriff of the county where the service
                  is to be made, or deputy; (2) any person not less than eighteen years of age appointed
                  for the purpose of serving summons; (3) any person authorized to serve process under
                  the law of the place outside this state where service is made; or (4) in the event
                  of service by mail or commercial delivery company, by the plaintiff or an attorney
                  of record for the plaintiff. Ark. R. Civ. P. 4(c).
               
               Louisiana: At the time of issuance of a child support order, the court shall order an immediate
                  income assignment. La. Rev. Stat. Ann. § 46:236.3(B) (1). The court effectuates the
                  income assignment order by providing written notice to the payor(s), advising the
                  payor(s) to withhold an amount for current support. Id. This statute does not specify
                  a particular manner of service for this written notice from the court.
               
               Where an obligor is delinquent on a child support obligation and an immediate income
                  assignment has not been issued, there are two ways an income assignment can be obtained
                  and served on a payor, such as SSA, depending upon whether the Department of Children
                  and Family Service (department) is providing services. Where the department is not
                  providing services, an obligee can seek to have an immediate income assignment effectuated.
                  La. Rev. Stat. Ann. § 46:236.3(C) (1). The obligee notifies the obligor of the delinquency
                  and of the intent to ask a court to issue an income assignment order. Id; see also
                  La. Rev. Stat. Ann. § 13:3204. If the obligor does not file a petition to stay service
                  of the income assignment order, a payor may be served with a notice to withhold an
                  amount for current support, plus an additional amount for any arrears, to be determined
                  by the court. La. Rev. Stat. Ann. § 46:236.3(C)(4). The statute does not specify a
                  particular method of service on the payor of this notice. Where the department is
                  providing services, the department may provide written notice to a payor to withhold
                  an amount for the current support, plus an additional amount, determined by the department,
                  toward any arrears. La. Rev. Stat. Ann. § 46:236.3(D)(1). The statute specifies that
                  in these instances, the department shall serve this notice upon a payor by certified
                  mail, regular mail, transmission by electronic means, or personal or domiciliary service.
                  La Rev. Stat. Ann. § 46:236.3(D)(1).

                  to withhold income. N.M. Stat. Ann. § 40-4A-4.1(B). The state's Title IV-D agency

               Where an obligor is delinquent on a child support obligation, the obligee or public
                  office agency (the New Mexico Human Services Department, Child Support Enforcement
                  Division, State Disbursement Unit) may prepare and serve notice of the delinquency
                  on the obligor, file a notice to withhold income with the clerk of the district court,
                  and serve the notice to withhold income on a payor, such as SSA, by certified mail
                  or personal delivery. N.M. Stat. Ann. §§ 40-4A-2(M), 40-4A-4, 40-4A-5(A), (B).

                  income withholding is binding against future payors by operation of law upon actual
                  knowledge of the contents of the order or notice, or upon receipt by personal delivery
                  or certified mail of a filed copy of the order or notice to the payor. N.M. Stat.
                  Ann. § 40-4A-8(F). This provision does not expressly limit who can serve the filed
                  copy of the order or notice on such a future payor.
               
               Oklahoma: At the time of issuance of a child support order, the Oklahoma Department of Human
                  Services or a person awarded child support by the district court or the Oklahoma Department
                  of Human Services may apply to collect any current child support or any child support
                  due and owing through a notice of income withholding, referred to as a notice of income
                  assignment. Okla. Stat. Ann. tit. 12, § 1171.2(A). To properly serve the notice of
                  income assignment on the payor, the applicant must send a notice of income assignment

                  of an order or judicial writ of withholding directing an employer, such as SSA, to
                  withhold an obligor's earnings for payment of child support. Tex. Fam. Code Ann. §§
                  101.0161, 158.001, 158.104, 158.105. The clerk of the court issues a judicial writ
                  of withholding directing and shall serve a certified copy of the order or judicial
                  writ of withholding to the obligor's current or subsequent employer by first-class
                  mail or, if requested, by certified or registered mail, return receipt requested,
                  by electronic transmission, including electronic mail, or facsimile transmission.
                  Tex. Fam. Code Ann. § 158.105(a),(c),(d).
               
               Where an obligor is delinquent on a child support obligation or an income withholding
