Chapter V: Depositions and Discovery · Not amended since adoption on record · Last verified July 14, 2026
Full Text of Rule 28
Plain-English Summary
Rule 28(a) covers depositions taken within the United States or a territory or insular possession under United States dominion: the deponent's oath must be administered by someone authorized to give oaths under federal law or the law of the place where the deposition happens, or by a person the court specially appoints for that purpose. Rule 28(b) addresses depositions taken in a foreign country, which can proceed in any of three ways — on notice before someone authorized to administer oaths where the examination occurs, before a person the court commissions to administer the oath and take testimony, or under a letter rogatory addressed to the appropriate authority in the country involved. A commission or letter rogatory issues on application and notice, on terms that are just and appropriate, and there is no requirement to show that taking the deposition another way would be impractical or inconvenient before using either method — both can even be issued together in the right case. Evidence obtained through a letter rogatory is not excluded merely because it is not a verbatim transcript, was not given under oath, or otherwise departs from the requirements that apply to depositions taken within the United States.
Rule 28(c) protects the deposition process from a conflict of interest at its source: no deposition can be taken before a person who is a relative, employee, attorney, or counsel of any party, who is a relative or employee of a party's attorney or counsel, or who has a financial interest in the action. That disqualification applies regardless of where the deposition is taken, and it keeps the person administering the oath and recording the testimony independent of the parties and their counsel.
Frequently Asked Questions
Who is authorized to administer the oath at a deposition taken in the United States?
Rule 28(a) authorizes anyone empowered to give oaths under federal law or the law of the place where the deposition happens, or a person the court has specially appointed to administer the oath and take the deposition.
How can a deposition be taken in a foreign country?
Rule 28(b) allows three methods: on notice before someone authorized to administer oaths in that country, before a person the court commissions to administer the oath and take testimony, or under a letter rogatory addressed to the appropriate authority in that country.
What is a letter rogatory, and does testimony obtained through one have to follow the same rules as a domestic deposition?
A letter rogatory is a formal request addressed to the appropriate authority of a foreign country to assist in obtaining testimony. Rule 28(b) states that evidence obtained this way is not excluded merely because it is not a verbatim transcript, was not taken under oath, or otherwise departs from the requirements that apply to depositions taken within the United States.
Do I need to show it would be impractical to depose someone in a foreign country another way before using a commission or letter rogatory?
No. Rule 28(b) specifically states that it is not a prerequisite to issuing a commission or letter rogatory that taking the deposition another way is impracticable or inconvenient, and both can be issued in the same case if appropriate.
Who is disqualified from taking or presiding over a deposition because of a conflict of interest?
Rule 28(c) disqualifies anyone who is a relative, employee, attorney, or counsel of a party, anyone who is a relative or employee of a party's attorney or counsel, and anyone financially interested in the outcome of the action.
