All interested parties will be specifically notified of the action taken by the agency of original jurisdiction in a simultaneously contested claim and of the right and time limit for submitting a Notice of Disagreement to the Board, as well as hearing and representation rights.

In simultaneously contested claims, any claimant or representative of a claimant may file a Notice of Disagreement within the time limits set out in Rule 402 (§ 20.402).

In simultaneously contested claims, the Notice of Disagreement from the person adversely affected must be filed within 60 days from the date of mailing of the notification of the determination to him or her; otherwise, that determination will become final. The date of mailing of the letter of notification will be presumed to be the same as the date of that letter for purposes of determining whether a Notice of Disagreement has been timely filed.

Upon the filing of a Notice of Disagreement in a simultaneously contested claim, all interested parties and their representatives will be furnished a copy of the substance of the Notice of Disagreement. The notice will inform the contesting party or parties of what type of review the appellant who initially filed a Notice of Disagreement selected under § 20.202(b), including whether a hearing was requested.

A party to a simultaneously contested claim may file a brief, argument, or request for a different type of review under § 20.202(b) in answer to a Notice of Disagreement filed by another contesting party. Any such brief, argument, or request must be filed with the Board within 30 days from the date the content of the Notice of Disagreement is furnished as provided in § 20.403. Such content will be presumed to have been furnished on the date of the letter that accompanies the content.

After expiration of the 30-day period for response in § 20.404, the Board will place all parties of the simultaneously contested claim on the docket for the type of review requested under § 20.202(b). In the event the parties request different types of review, if any party requests a hearing the appeal will be placed on the docket described in § 20.800(a)(iii), and VA will notify the parties that a hearing will be scheduled. If no party requested a hearing, but any party requested the opportunity to submit additional evidence, the appeal will be placed on the docket described in § 20.800(a)(ii), and the parties will be notified of their opportunity to submit additional evidence within 90 days of the date of such notice.

Notices in simultaneously contested claims will be forwarded to the last address of record of the parties concerned and such action will constitute sufficient evidence of notice.

Where a claim is contested, findings favorable to either party, as described in Rule 801 (§ 20.801), are no longer binding on all agency of original jurisdiction and Board of Veterans' Appeals adjudicators during the pendency of the contested appeal.
