Unsigned Deposition Notice Struck
Deborah Dunn's lawyer prepares a notice to take the deposition of Darius Dixon but omits the required signature and contact details. The opposing party moves to strike the notice. The court strikes the unsigned paper because every written motion and other paper must bear the signer's name and contact information.
Prior Deposition Used for Impeachment
Destiny Davis testifies at trial that she never saw the defendant at the scene. Counsel offers her earlier deposition statement, given under oath, in which she identified the defendant. The court admits the deposition testimony as non-hearsay because it is inconsistent with her current testimony and was given under penalty of perjury.

Deposition Affidavit in Warrant Application
Officers attach Dominic Drake's deposition transcript to an affidavit seeking a search warrant for a warehouse. The warrant itself lists only the address and fails to describe any items to be seized. The court suppresses the evidence because the warrant is facially deficient even though the supporting deposition supplied detailed information.
Criminal Deposition to Preserve Testimony
Dominic Drake moves to depose a terminally ill eyewitness before trial because the witness may be unavailable. The court grants the motion on a finding of exceptional circumstances and orders production of relevant documents at the deposition. The preserved testimony is later admitted at trial.
Deposition Supporting Temporary Support Motion
Dolores Diaz files for dissolution and moves for temporary child support. She attaches excerpts from Darius Dixon's deposition describing his income and the child's needs. The court awards temporary support after reviewing the deposition testimony along with the required affidavit.
Deposition Taken Without Leave of Court
Danielle Dixon serves a notice to depose a non-party witness ten days after the defendant is served with the complaint. No stipulation or court order is obtained. The deposition proceeds because leave of court is not required when the parties have not stipulated otherwise and the witness is not a prisoner.
