What is unlawful for a registrant to do regarding their seal after expiration?

Stamping documents with an expired seal is unlawful because a seal signifies that the person who prepared the document is in good standing and authorized to practice within their profession. Once the seal has expired, the registrant no longer has the authority to represent themselves as qualified, which invalidates any documents stamped with that seal. This action is considered misleading since it implies that the document has been prepared or overseen by someone who is currently licensed and authorized, which is not the case if the seal is expired.

In addition to this, using an expired seal could legally jeopardize both the registrant and the validity of the document, as it does not comply with the standards of practice required in the profession. Other options relate to actions that are discouraged but may not specifically denote the same level of illegality as using an expired seal on a document.
