Mention my name.
The following may help. I am attaching a Memo I prepared for the Bar in Maryland that confirms the proposition that it is not necessary for both parties to consent to the entry of a QDRO. One of the documents I reference is a Department of Labor pamphlet dealing with QDROs where it states at Question 1.2, 6th paragraph on page 5:
"There is no requirement that both parties to a marital proceeding sign or otherwise endorse or approve an order."
[ERISA §§ 206(d)(3)(B)(ii), 514(a), 514(b)(7); IRC § 414(p)(1)(B)]
The law in Nevada may be the same,. See Mack v. Estate of Mack, that you can find at -
https://scholar.google.com/scholar_case?case=2457338442981582706&q=must+both+parties+sign+qdro&hl=en&as_sdt=4,29
where in 2009 the Supreme Court of Nevada approved an oral QDRO which obviously was not and could not have been signed by the parties. In fact, The language of the Court was:
" The district court issued a valid QDRO during Charla's lifetime. In the January 9 hearing, Judge Weller stated that within 48 hours, "a QDRO will be executed which will transfer to Mrs. Mack the sum of five hundred thousand dollars with any appreciation that is distributed to that five hundred thousand dollars and more or less equal installments over a period of five years." Here, the court issued a QDRO, because Judge Weller's oral order created a recognized existence in Charla, the right to receive a portion of Darren's ERISA pension plan. See id. § 1056(d)(3)(B)(i)(I). Because the district court issued a DRO, which was qualified, and it recognized Charla as an alternate payee with the right to receive a $500,000 payment from Darren's ERISA pension plan, we conclude that the QDRO was valid and affirm the order of the district court."
So if the impediment in your case is the need to have the QDRO signed by both parties, the foregoing should be evidence that it is not necessary.
Once again, the purpose of the QDRO is to IMPLEMENT the written Agreement of the parties, or, if they parties did not agree, the Order of the Court allocating pension and retirement benefits must likely issued in the Judgment of Divorce.
Good luck
