TN Code § 36-5-3103 (2021)
2021 Tennessee Code|Title 36 - Domestic Relations|Chapter 5 - Alimony and Child Support|Part 31 - Enforcement Without Transfer of Jurisdiction|§ 36-5-3103. Registration of Order for Enforcement

  A support order issued by a court of this state may be registered in the county in this state where the child or children reside, for enforcement purposes only. If the case is a Title IV-D support case, at the option of the department, it may be enforced in the county of the residence of the obligor. The order may be modified in this state in a court other than the issuing court only if transferred pursuant to part 30 of this chapter. A support order issued by a court in one county may be registered in another county by the person or agency seeking only enforcement of the original order against a support obligor by sending the following documents and information to the appropriate court in the registering county:  One (1) certified copy of all orders to be registered, including any modification of an order;   A letter or transmittal document that includes the following information:  The name of the obligor, and if known:   The obligor's address and social security number;   The name and address of the obligor's employer and any other source of income of the obligor; and     The name and address of the obligee and, if applicable, the agency or person to whom support payments are to be paid;     A sworn statement by the party seeking registration or a certified statement of the clerk of the court or custodian of the records showing the amount of any arrearage being sought to be enforced unless the case is being enforced by the department of human services pursuant to Title IV-D of the Social Security Act (42 U.S.C. § 651 et seq.), in which situation the department's child support computer system, if operative for the transferor and transferee court at the time of the transfer, shall be used as the child support payment record and the clerk or custodian shall not be required to prepare the certified statement of the child support payment record;   A copy of a notice, with the address of the nonrequesting party, to be sent by the clerk of the registering court or the department in Title IV-D child support cases to the nonrequesting party pursuant to § 36-5-3105, that states:  That a registered order is enforceable as of the date of registration in the same manner as an order issued by a court of the registering county;   That a hearing to contest the validity or enforcement of the registered order must be requested to the registering court within fifteen (15) days after the date of mailing of the notice;   That failure to contest the validity or enforcement of the registered order in a timely manner will result in confirmation of the order by operation of law, will result in enforcement of the order and the alleged arrearages, and will preclude further contest of that order with respect to any matter that could have been asserted;   The amount of any alleged arrearages; and   That, if the registered order is confirmed by operation of law or by court order, all payments made under the order shall be made to the clerk of the registering court or to the department of human services, or another clerk, as appropriate.       On receipt of a request for registration, the registering court shall cause the order to be filed, together with one (1) copy of the documents and information, regardless of their form.   A petition seeking a remedy that must be affirmatively sought may be filed at the same time as the request for registration or may be filed later.   All payments received by the issuing court after the order has been registered shall be sent by the clerk of the issuing court to the clerk of the registering court, or the department of human services if the clerk of the registering court is not participating in the child support enforcement system, without credit being given to the obligor by the clerk of the issuing court.
