Notaries in Delaware play a critical role in safeguarding the authenticity of legal and business documents. At the heart of this responsibility lies one essential tool: the notary stamp or seal. Delaware law requires notaries to use an official stamp to validate most notarial acts, ensuring that documents are trusted by courts, agencies, and the public alike.
This article explains Delaware’s statutory requirements, design standards, and best practices for notary seals, offering clarity for both new and experienced notaries.
Legal Requirement for Seals in Delaware
Delaware law clearly requires the use of an official stamp in most notarizations. The official stamp is what makes a notarial certificate complete and enforceable under the state’s Revised Uniform Law on Notarial Acts.
For tangible (paper) documents, the notary’s official stamp must always be affixed to the certificate of notarial act. For electronic documents, the official stamp may be attached; however, it is not mandatory if the certificate already contains all the legally required elements.
Statutory Breakdown of Seal Rules
Delaware follows the Revised Uniform Law on Notarial Acts (RULONA). This framework establishes the rules for when an official stamp is required, the information that must appear in the notarial certificate, and the manner in which the notary signs the record.
Understanding these rules helps notaries avoid costly mistakes and ensures that their acts are recognized as legally valid.
Tangible Records
For paper documents, the certificate of notarial act must include the notary’s official stamp, along with the notary’s signature, the date, jurisdiction, and commission expiration.
Electronic Records
For electronic records, the notarial certificate must contain all required elements, such as the signature, jurisdiction, and expiration date of the commission. An electronic stamp may be attached, but it is optional if the certificate already satisfies the content requirements.
Certificate Elements
Every notarial certificate must identify the jurisdiction, state the notary’s title of office, be signed and dated, and include the commission expiration date. Missing any of these elements can result in the rejection of the notarized document.
Design and Format Requirements
Delaware law does not prescribe exact dimensions, shapes, or ink colors for stamps. Instead, the focus is on the content of the stamp and whether it can be copied together with the record. This flexibility enables notaries to select tools that best suit their practice while still complying with state law.
The most essential requirement is that the stamp be legible and reproducible, whether affixed in physical or electronic form.
Required Wording
The official stamp must display:
- The notary’s name is exactly as on file with the state
- The words “State of Delaware”
- The phrase “My Commission expires on [date]” with the commission expiration date
- Any additional information required by the Secretary of State
Copyability
The stamp must be capable of being copied together with the record it is attached to. This ensures that scanned or photocopied documents remain valid and recognizable as notarized.
Format Options
Both embossed seals and rubber ink stamps qualify as official stamps, provided they meet the content and copyability requirements. For electronic notarizations, an electronic image of the official stamp may be used if applied in a secure and verifiable manner.
Special Notes and Considerations
While Delaware’s law provides flexibility, there are a few essential details notaries should keep in mind. These considerations make the difference between a compliant notarial act and one that may be challenged or rejected.
Understanding these points ensures that notaries are well-prepared for both paper and electronic notarizations.
Embossers
Embossers remain permissible as long as the impression clearly shows the required information and can be copied with the record. Many notaries supplement embossers with an ink stamp to ensure legibility.
Electronic Seals
Electronic seals are optional under Delaware law, but many notaries choose to use them for consistency and clarity. If used, they must meet the content requirements and be securely attached to the electronic record.
Recent Updates
The Revised Uniform Law on Notarial Acts took effect in Delaware on August 1, 2023. This modernized framework replaced the old statutes and gave clear rules for both tangible and electronic records. Notaries should make sure they are following the updated provisions.
Why the Seal Matters
The notary seal is more than a formality. It is the visible mark of authority that provides assurance of authenticity, legality, and compliance. Without it, many notarizations may be rejected outright.
By affixing their official stamp properly, Delaware notaries not only fulfill their legal obligations but also enhance public confidence in the documents they certify.
Validity of Documents
A notarization without an official stamp on a paper record is incomplete and risks rejection by banks, agencies, or courts. For electronic records, failure to include all certificate elements may render the act invalid.
Fraud Prevention
The official stamp ties the act to a commissioned Delaware notary, making it harder for fraudsters to forge documents. It adds a traceable element of authenticity.
Professional Trust
Evident, compliant seals signal professionalism. Clients and institutions rely on them as a sign that the notary’s act is both lawful and trustworthy.
Best Practices for Delaware Notaries
Best practices ensure that notaries stay compliant and that their work is consistently accepted. By following these habits, notaries in Delaware protect themselves and the people they serve.
These steps apply whether a notary works primarily with paper documents or is transitioning into electronic notarization.
Use a High-Quality Seal
Select a durable, state-compliant stamp or embosser that produces a clear impression. Delaware notaries should invest in a high-quality, state-approved notary stamp to stay compliant.
Verify Your Seal Regularly
Check the clarity of your stamp often. Replace it immediately if it becomes worn, faint, or difficult to reproduce.
Maintain Security
Your official stamp is your responsibility alone. Never lend it to others, and report a lost or stolen stamp promptly.
Stay Current
Monitor the Delaware Secretary of State’s website for updates. The adoption of RULONA and electronic notarization shows how quickly laws can evolve.
Record Consistently
Always apply your stamp at the same time you complete the notarial act. Never stamp documents ahead of time or after they have been signed.
Prepare for Digital Workflows
As electronic notarization grows, notaries should familiarize themselves with secure platforms.
Notaries transitioning to electronic notarization should still equip themselves with reliable traditional Stamps and Seals.
Importance of Following Seal Rules
Delaware notaries must understand that the official stamp is not only a legal requirement but also a public safeguard. It is essential for validity, trust, and protection against fraud.
By mastering both the statutory rules and best practices, notaries can confidently serve the public and maintain the highest standards of their office. The notary seal is a daily reminder of this responsibility.
