Rule 25 - Filing and Service(a)Filing. Documents required or permitted to be filed in the appellate court must be filed with the clerk. Filing may be accomplished by e-filing pursuant to C.A.R. 30, by mail addressed to the clerk, or by hand delivery to the clerk's office. The date of filing of documents is the date they are received by the clerk regardless of method of filing.(b) Inmate Filings. Documents filed by an inmate confined to an institution will be deemed filed when filed in accordance with C.A.R. 25(b). Documents filed by an inmate confined in an institution are timely filed with the court if deposited in the institution's internal mailing system on or before the last day for filing. If an institution has a system designed for legal mail, the inmate must use that system to receive the benefit of this rule.(c) Service of all Documents Required. Copies of all documents filed by any party and not required by these rules to be served by the clerk must, at or before the time of filing, be served by a party or person acting for that party on all other parties to the appeal or review. Service on a party represented by counsel must be made on counsel.(d) Manner of Service. Service may be personal, by mail, e-mail, or E-Service as defined in C.A.R. 30(a)(4). Personal service includes delivery of the copy to a clerk or other responsible person at the office of counsel. If a self-represented party is served by e-mail, the serving party's certificate of service must verify that service was made via e-mail and include both the self-represented party's email address and postal address. E-Service is complete upon the time and date of transmission by the E-Service provider. Registered parties using E-Service must complete service in the appellate court case in which the documents are filed; the appellate courts will not accept service of documents made in the underlying proceedings.(e) Proof of Service. Documents presented for filing must contain an acknowledgment of service by the person served or proof of service in the form of a statement of the date and manner of service and of the names of the person served, certified by the person who made service. Proof of service may appear on or be affixed to the documents filed. The clerk may permit documents to be filed without acknowledgment or proof of service but shall require such to be filed promptly thereafter.Source: Entire rule amended and adopted May 17, 2001, effective 7/1/2001; d amended and effective 2/7/2008; amended and adopted by the Court, En Banc, March 23, 2023, effective 3/23/2023.
