Plain-English Summary
Every deposition needs someone with legal authority to put the witness under oath, and Rule 38 supplies that authority. Inside Oregon, that authority belongs to anyone the state already allows to administer oaths, or to a person the court specially appoints just for that deposition. A deposition taken by remote means under Rule 39 still counts as taken within Oregon as long as either the witness or the person administering the oath is physically located here. Outside Oregon, the rule offers three routes: before a person authorized to administer oaths where the deposition takes place, before a person the Oregon court appoints or commissions, or under a formal letter rogatory addressed to the authorities of the other state or country. Getting a commission or a letter rogatory doesn’t require first showing that one of the other routes would be impractical, and evidence gathered abroad in response to a letter rogatory isn’t automatically thrown out just because it doesn’t look like a standard Oregon deposition transcript.
Section C addresses the reverse situation: someone suing in another state who needs to depose a witness or gather documents located in Oregon. Rather than asking an Oregon court to issue a subpoena from scratch, the out-of-state litigant submits the foreign subpoena to the clerk of court in the Oregon county where the discovery will happen. The clerk opens a case number and issues an Oregon subpoena that can borrow language from the foreign one, so long as it still follows Oregon’s own subpoena rules and lists contact information for the lawyers and any unrepresented parties involved. Submitting the subpoena for issuance isn’t treated as an appearance before the Oregon court, but filing a motion to enforce, quash, or modify that subpoena is, and that motion goes to the court in the county where the discovery is happening.
Frequently Asked Questions
Who is allowed to put a deposition witness under oath in Oregon?
Anyone the state already authorizes to administer oaths, or a person the court specially appoints just for that particular deposition. Either way, that person has the authority to swear in the witness before the questioning begins.
If my deposition happens over video, is it considered taken in Oregon?
Yes, as long as either the witness or the person administering the oath is physically located in Oregon at the time, a remote deposition under Rule 39 counts as taken within the state.
What is a letter rogatory, and when is one used?
A letter rogatory is a formal request addressed to the appropriate authority of another state, territory, or country, asking that authority to take testimony or gather evidence there. It’s issued on application and notice, and a party doesn’t have to show that taking the deposition some other way would be impractical before requesting one. Evidence gathered this way isn’t automatically excluded just because it doesn’t look like a standard Oregon deposition or wasn’t taken under oath in the usual sense.
I’m suing someone in another state and need discovery from a witness in Oregon. How do I get a subpoena?
Submit the foreign subpoena to the clerk of court in the Oregon county where the discovery is sought. The clerk assigns a case number and issues an Oregon subpoena that follows Oregon’s own subpoena rules, and it must include contact information for the lawyers and any unrepresented parties in the out-of-state case.
Does asking an Oregon court to issue a subpoena for an out-of-state case subject me to that court’s authority?
No. Submitting the foreign subpoena for issuance isn’t treated as an appearance before the Oregon court. Filing a motion to enforce, quash, or modify that subpoena is different — that counts as an appearance and must be filed in the county where the discovery is happening.
