Any claimant may amend a filed claim as of right by filing a Notice of Amendment during the statutory period for filing annual claims. After the expiration of the time for filing claims, a claimant may amend a filed claim as of right to correct the general description of the nature of the claimant's work(s), to fix typographical or other nonsubstantive errors in other portions of the claim, or to strike a claimant or interested copyright party that was erroneously included in a joint claim. No filer may amend a filed claim to add additional claimants or interested copyright parties after the expiration of the time for filing claims. All Notices of Amendment must be filed online through eCRB.

Any claimant may withdraw its claim for any royalty year as of right by filing a Notice of Withdrawal of Claim(s). If a single claimant filed a Petition to Participate in a proceeding, withdrawal of the claim shall serve to dismiss the Petition to Participate. If the claimant withdrawing a claim was included on the Petition to Participate of another entity, withdrawal of the claim shall not affect the Petition to Participate as to other claims listed thereon. All Notices of Withdrawal of Claim(s) must be filed online through eCRB.

Once a claimant has withdrawn a claim, that claim may be reinstated only by order of the Copyright Royalty Judges, on motion showing good cause and lack of prejudice to other claimants to the applicable year's royalty funds.
