Chapter 4000 - DEPOSITIONS AND DISCOVERY
Rule 4005 - Written Interrogatories to a Party

(a) Subject to the limitations provided by Rule 4011, any party may serve upon any other party written interrogatories to be answered by the party served or, if the party served is a public or private corporation or similar entity or a partnership or association, by any officer or agent, who shall furnish such information as is available to the party. Interrogatories may be served upon any party at the time of service of the original process or at any time thereafter. Interrogatories which are to be served prior to service of the complaint shall be limited to the purpose of preparing a complaint and shall contain a brief statement of the nature of the cause of action. Interrogatories shall be prepared in such fashion that sufficient space is provided immediately after each interrogatory or subsection thereof for insertion of the answer or objection.

(b) Rescinded.

(c) Interrogatories may relate to any matters which can be inquired into under Rules 4003.1 through 4003.5 inclusive and the answers may be used to the same extent as provided in Rule 4020 for the use of the deposition of a party. Interrogatories may be served after a deposition has been taken, and a deposition may be taken after interrogatories have been answered, but the court, on motion of the party interrogated, may make such protective order as justice requires. The number of interrogatories or of sets of interrogatories to be served may be limited as justice requires to protect the party from unreasonable annoyance, embarrassment, oppression, burden or expense.
