Default judgment prove-ups

Live testimony is required at prove-up hearings. While the Court prefers witnesses testifying live at the prove-up hearing, telephonic testimony appearances are permitted if a notary public is present with the witness for the purpose of administering the Oath to the witness.  Video appearances are also allowed.

Submission of Orders

  • Department 18 requires proposed orders to be submitted electronically to the department inbox within ten (10) days of notification of the ruling, pursuant to EDCR 7.21.  DC18Inbox@clarkcountycourts.us Counsel designated to prepare the order is required to provide a draft to opposing counsel(s), allowing for a reasonable opportunity for review and comment.

Contested Orders

  • If both sides cannot agree, each side may submit their own proposed Order for approval of the Judge.  Any competing order without obtaining opposing counsel's signature must be accompanied by a brief 1-page cover letter with bullet-points highlighting each instance of contested language and the reasons for the competing order.
  • Competing orders must be submitted to the DC18inbox@clarkcountycourts.us no later than 10 days from receipt of the first proposed order from adverse counsel.
  • Instead of seeking to litigate any disapproval through correspondence directed to the Court or to counsel with copies to the Court, any such disapproval should be the subject of motion practice following entry of order.
  • Letters to the Court containing substantive argument on the merits of a contested proposed order are disfavored, viewed as improper ex parte communications, even if copied to opposing counsel, and will not be considered.

Electronic signatures

  • With the exception of documents requiring the signature of a notary, an electronic signature will be considered an original signature. All documents requiring a signature of another person may be electronically signed; however, the party submitting the document must obtain e-mail verification of the other person’s agreement to sign electronically. That verification must be embedded in the document or attached as the last page of the document.

Jury selection

  • Department XVIII uses the “Arizona Method” of jury selection, requiring voir dire to be directed toward the minimum number of jurors necessary to be qualified, rather than the entire venire.
