Section 405 - Income withholding hearing(a) At any hearing contesting proposed income withholding based on a support order entered under § 403 of this title, the entered order, accompanying sworn or certified statement, and a certified copy of an income withholding order, if any, still in effect shall constitute prima facie proof, without further proof or foundation, that the support order is valid, that the amount of current support payments and arrearages is as stated, and that the obligee would be entitled to income withholding under the law of the jurisdiction which issued the support order.(b) Once a prima facie case has been established, the obligor may raise only those defenses set forth in § 513(b)(3) of this title. The burden shall be on the obligor to establish these defenses.(c) If the obligor presents evidence which constitutes a full or partial defense, the court shall, on the request of the obligee, continue the case to permit further evidence relative to the defense to be adduced by either party; provided, however, that if the obligor acknowledges liability sufficient to entitle the obligee to income withholding, the court shall require income withholding for the payment of current support payments under the support order and of so much of any arrearages as is not in dispute, while continuing the case with respect to those matters still in dispute. The court shall determine those matters still in dispute as soon as possible, and if appropriate shall modify the withholding order to conform to that resolution.(d) In addition to other procedural devices available to a party, any party to the proceeding or a guardian ad litem or other representative of the child may adduce testimony of witnesses in another state, including the parties and any of the children, by deposition, by written discovery, by photographic discovery such as videotaped depositions or by personal appearance before the court by telephone or photographic means, or by any other device specified in § 6-316(f) of this title. The court on its own motion may direct that the testimony of a person be taken in another state and may prescribe the manner in which and the terms upon which the testimony shall be taken.(e) A court of this State may request the appropriate court or agency of another state to hold a hearing to adduce evidence, to permit a deposition to be taken before the court or agency, to order a party to produce or give evidence under other procedures of that state and to forward to the court of this State certified copies of the evidence adduced in compliance with the request.(f) Upon request of a court or agency of another state, the courts of this State which are competent to hear support matters may order a person in this State to appear at a hearing or disposition before the court to adduce evidence or to produce or give evidence under other procedures available in this State. A certified copy of the evidence adduced, such as a transcript or videotape, shall be forwarded by the Clerk of Court to the requesting court or agency.(g) A person within this State may voluntarily testify by statement or affidavit in this State for use in a proceeding to obtain income withholding outside this State.65 Del.
