The AI checks your answers before you download

12 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Seller Number Format and Length

This check verifies that each provided Fannie Mae seller number (Seller Number 1 through 4) consists of exactly five digits. It is important to ensure the number is a valid identifier in the system. If the field contains non-numeric characters or has a length other than five, the submission should be rejected with an error prompting the user to enter a valid five-digit number.

At Least One Seller Number Required

Validates that at least 'Seller Number 1' is filled out. The form is intended to apply to one or more seller numbers, so at least one must be provided for the form to have a subject. If 'Seller Number 1' is empty, the form submission should be blocked until a valid number is entered.

Seller Name Consistency Across Sections

This validation compares the 'Seller Name' field from the top of the form with the 'Seller Legal Name' field in the 'Resolution/Evidence of Authorizations' section. These two fields must be an exact match to ensure the authorization is being applied to the correct legal entity. A mismatch could indicate a data entry error or an incorrect document, and the user should be prompted to correct the discrepancy.

Valid and Historical Authorization Date

Ensures that the combination of 'Authorization Month', 'Authorization Day', and 'Authorization Year' forms a valid calendar date. Furthermore, it checks that this date is not in the future, as an authorization cannot be granted for a future date. If the date is invalid or in the future, the user must correct the date components before proceeding.

Valid Signature Date

This check confirms that the 'Date Signed (Month)', 'Date Signed (Day)', and 'Date Signed (Year)' fields combine to form a valid calendar date. This prevents impossible dates, such as February 30th, from being entered. An invalid date would invalidate the signature, so the user must correct it.

Logical Date Sequence

Verifies that the 'Date Signed' is on or after the 'Date of Authorization'. A document cannot be legally signed before the authority to sign has been granted. If the signature date precedes the authorization date, it represents a logical impossibility, and the user must correct one or both of the dates.

Common Mistakes in Completing Fannie Mae Form 10

The ones the AI is built to catch.

Inconsistent or Incomplete Seller Name
The form has multiple fields for the seller's name ('Seller Name', 'Seller Name Line 1/2', 'Seller Legal Name'), which can lead to users entering different variations like 'ABC Corp.' vs. 'ABC Corporation, Inc.' This redundancy often causes confusion and mismatches. Any inconsistency in the legal entity name can cause the document to be rejected for compliance reasons, leading to significant processing delays. To avoid this, carefully enter the full, official legal name as registered, ensuring it is identical in all corresponding fields across the document.
Incorrect Fannie Mae Seller Number Format
Users might accidentally enter a number with more or fewer than the required five digits, include non-numeric characters, or transpose digits due to manual data entry errors. An incorrect seller number will fail system validation, causing the submission to be rejected immediately. This requires correction and resubmission, delaying the entire authorization process. Always double-check that each seller number is exactly five digits and contains only numbers before submitting.
Transposing Date Fields (Month/Day)
The form separates dates into distinct Month, Day, and Year fields, which is a common source of error. Users, especially those accustomed to international date formats (DD/MM/YYYY), may accidentally enter the day in the month field and vice-versa. An incorrect authorization or signature date can invalidate the document, as the timing is a critical legal component, requiring the form to be re-signed and re-submitted. Pay close attention to the field labels or use an AI form-filling tool that correctly structures the date based on the form's requirements.
Mismatching Authorized Individuals with Titles and Signatures
The form lists fields for up to ten individuals, each requiring a name, title, and signature. With so many fields, it's easy to enter a name in one slot but the wrong title, or have the wrong person sign in that signature block, especially given the non-sequential field order. Misaligned information can invalidate an individual's authorization, leading to compliance issues and rejection of transactions they attempt to perform. To prevent this, methodically fill out all information for one individual at a time before moving to the next.
Missing Signatures or Titles for Authorized Individuals
On a form with up to 10 signature lines and corresponding title fields, it is common for users to overlook one or more required entries. They may fill in a name but forget the associated title or miss a signature box entirely, especially on a multi-page document. An incomplete form is invalid and will be returned, halting the process until all information is provided correctly. Before submitting, perform a final review specifically to check that every listed individual has a corresponding title and signature.
Confusion Between 'Signer' and 'Authorized Individual'
The form has a distinct 'Signer Information' section separate from the list of 'Authorized Individuals.' Users may mistakenly believe any authorized individual can sign, when the signer must be a corporate officer with the legal authority to certify the list itself (e.g., a Corporate Secretary or President). If the form is signed by someone without the proper authority, the entire document is legally void, leading to serious repercussions. Always verify who has the corporate authority to attest to the information and ensure they are the one to sign in the 'Signer Information' section.
Providing Ambiguous Information in the Resolution Section
The final section asks for 'Authorized individuals and/or titles,' which is an ambiguous instruction that users interpret differently. Some may provide only a name, while others provide only a title, leading to incomplete data. This ambiguity can lead to requests for clarification, delaying approval. Despite the 'and/or' wording, the best practice is to always provide both the full name and the full title for each individual to ensure maximum clarity and avoid rejection.
Typos in Contact Email or Phone Number
A simple but frequent data entry error is a typo in the contact email or phone number, often caused by typing too quickly. A single wrong character (e.g., '[email protected]') or a transposed digit renders the contact information useless. If the form processor has a question, they will be unable to reach the contact person, causing the form to be rejected when a quick call could have resolved the issue. AI form-filling tools like Instafill.ai can help by saving and accurately auto-filling validated contact information.
Entering Data in Non-Sequential Fields
The form's underlying field structure appears non-sequential (e.g., listing fields for the first, then third, then second authorized individual). This confusing layout makes it highly probable that a user will manually enter information into the wrong field. This leads to a jumbled and inaccurate record that will be rejected, requiring a painstaking correction and resubmission process. To avoid this, use a tool like Instafill.ai that can present the fields in a logical order while mapping the data correctly in the background.
Forgetting to Sign the Form
With 11 separate signature fields spread across the document, it is very common for at least one required signature to be missed. This is especially true if the form is printed and passed between multiple people for physical signatures. An unsigned or partially signed form is legally incomplete and will be rejected immediately, forcing the entire signing process to start over. If the form is a non-fillable PDF, a tool like Instafill.ai can convert it to a fillable version with clearly marked signature fields to ensure none are missed.
