Yes. You can dissolve a partnership with an existing MC number by submitting a notarized letter signed by both partners requesting that the partner be removed from the existing authority.
If the partners cannot agree who should keep the existing MC number:
- They should both file a new application with the required fees and get new MC numbers
- They should request that the existing MC number be voluntarily revoked. See the FAQ “How can I suspend or put my operating authority (MC number) on hold?”
