Notarization plays a crucial role in ensuring the authenticity and legality of important documents. Whether you need a power of attorney, real estate transaction, or an apostille, avoiding common mistakes during the notarization process is essential. At Sonoma County Mobile Notary & Apostille, we take pride in helping individuals and businesses in Santa Rosa, Petaluma, Rohnert Park, Novato and surrounding areas notarize documents correctly and efficiently. Here are the top five mistakes to avoid—and how our expertise prevents them.
1. Missing or Incorrect Signatures
One of the most common errors in notarization is missing or incorrectly placed signatures. Some documents require the signer to sign in front of the notary, while others may need initials on specific pages. Failing to follow these requirements can invalidate the document, leading to unnecessary delays.
How We Help: Our expert mobile notary service ensures that all necessary signatures are completed correctly before finalizing the notarization, preventing costly mistakes.
2. Lack of Proper Identification
California law requires signers to present valid, government-issued identification for notarization. Expired IDs, incomplete names on documents that don’t match the ID, or missing identification altogether can halt the process.
How We Help: We verify all IDs in advance, ensuring compliance with California notary laws. If identification issues arise, we guide clients on acceptable alternatives to keep the process moving smoothly.
3. Not Understanding Document Requirements
Certain documents require additional steps, such as an apostille for international use, witness signatures, or specific notarial certificates. Many clients are unaware of these requirements, leading to rejected documents.
How We Help: Our experience in notarizing estate planning documents, real estate closings, apostille services, and power of attorney forms allows us to identify potential issues before they become problems. We offer guidance on notarization requirements, ensuring compliance and acceptance.
4. Using the Wrong Notarial Certificate
Notaries cannot choose the type of notarization a document needs—that decision must be made by the signer or the requesting agency. However, incorrect certificates (acknowledgment vs. jurat) are a frequent cause of rejected documents.
How We Help: We provide clear explanations of each notarial act and ensure that clients select the correct type of notarization for their specific document. Our goal is to ensure your documents meet legal and institutional requirements.
5. Notary Errors or Missing Seal
Even small notary mistakes—such as incorrect dates, missing notary stamps, or incomplete certificates—can render a document invalid. These errors can cause delays, requiring additional appointments and corrections.
How We Help: Our meticulous attention to detail ensures every document is properly completed, stamped, and compliant with California notary laws. We double-check our work to guarantee accuracy before finalizing the notarization.
