D.C. Mun. Regs. tit. 17, r. 17-2406
When the seal of a notary public commissioned by ONCA or the electronic seal of an electronic notary is lost or stolen, the notary public or electronic notary shall notify ONCA, in writing, or by email to notary@dc.gov, within ten (10) business days of discovering the seal was lost or stolen.
The notary public or electronic notary may not obtain a replacement official seal until they have properly notified ONCA in writing, or by email to notary@dc.gov, that the original was lost or stolen.
A replacement official seal must contain some variance from the original seal, and the notary public or electronic notary must provide ONCA an impression of the new seal.
If the original seal or electronic seal, which was lost or stolen, is found or recovered after a replacement has been obtained, the notary public or electronic notary shall destroy the original seal.
