What this form asks for

The AI fills all of it, from your answers or your documents.

The California Form MC-030, Declaration, is a legal document used in court proceedings to present written testimony. The person signing it (the declarant) swears under penalty of perjury that the statements made are true and correct, giving it the same legal weight as sworn testimony in court. This form is crucial for providing evidence, supporting motions, or offering factual accounts without requiring a live court appearance. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

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

Attorney or Party Information Completeness

Verifies that the top section for 'ATTORNEY OR PARTY WITHOUT ATTORNEY (Name, State Bar number, and address)' is not empty. This information is critical for identifying the filer of the document and for all future correspondence. If this section is left blank, the court cannot process the filing as the submitting party is unknown.

State Bar Number Format

Checks if the State Bar number, when provided, consists only of numerical digits. This validation ensures that if an attorney is filing the document, their identifying bar number is in a valid format for verification. An invalid format could lead to rejection or delays in processing.

Case Number Presence

Ensures the 'CASE NUMBER' field is filled out. The case number is the unique identifier for the legal proceeding, and this declaration must be associated with it. A missing case number would make it impossible for the court clerk to file the document in the correct case file.

Party Identification Completeness

Validates that both the 'PLAINTIFF/PETITIONER' and 'DEFENDANT/RESPONDENT' name fields are populated. These fields are essential for correctly identifying the primary parties of the case to which this declaration applies. Failure to identify the parties can lead to the document being rejected.

Declarant Role Selection

Checks that at least one of the checkboxes (Plaintiff, Defendant, Petitioner, Respondent, or Other) is selected to identify the declarant. It is legally necessary to know who is making the declaration. If no role is selected, the declaration has no clear author and is invalid.

Conditional Requirement for 'Other' Declarant

If the 'Other (Specify)' checkbox is selected, this validation ensures the adjacent text field is not empty. This is important because the court needs to understand the relationship of the declarant to the case if they are not one of the primary parties. An empty specification for an 'Other' declarant makes their role ambiguous.

Common Mistakes in Completing MC-030

The ones the AI is built to catch.

Missing or Incorrect Case Number
Entering the wrong case number or leaving it blank is a frequent and critical error. This often happens due to a simple typo or not having the case file readily available. An incorrect case number can lead to the court clerk rejecting the filing or misfiling the document, causing significant delays and potentially resulting in missed deadlines. Always double-check the case number against official court documents before submission; AI-powered tools like Instafill.ai can help by saving and auto-populating recurring case information to prevent such transcription errors.
Failing to Sign the Declaration
An unsigned declaration is legally invalid and will be rejected by the court, rendering the entire submission useless. People often forget this final step in their haste to complete the form. It is crucial to physically or digitally sign the document in the designated signature box above the printed name. This signature affirms that the statements are made under penalty of perjury.
Improperly Filling the 'Attorney For' Section
This section is frequently misunderstood, especially by individuals representing themselves (pro se litigants). They may leave it blank or write 'N/A'. A pro se litigant should enter their own name or 'In Pro Per', while an attorney must list their client's name. An incorrect entry can cause confusion about who is making the declaration and on whose behalf, potentially delaying the case. Using a guided form-filling tool can help clarify what information is required for each field based on user role.
Incorrect Court and Branch Name Information
Filers often list the main county courthouse address instead of the specific branch where the case is being heard. This can cause the document to be sent to the wrong location, leading to filing delays or rejection. To avoid this, verify the exact street address and branch name for your specific case on the court's website. AI-powered form fillers like Instafill.ai can store correct court addresses, ensuring consistency and accuracy across all documents for a case.
Forgetting to Date and Print Name in the Signature Block
Besides the signature, the signature block requires a date and the declarant's typed or printed name. Omitting either of these can call the document's validity into question, as it makes it difficult to identify the signer and when they signed. The date should be the actual date of signing. Always complete the entire signature block—date, signature, and printed name—to ensure the declaration is accepted by the court.
Illegible Handwriting on Non-Fillable Forms
Many court forms are only available as flat, non-fillable PDFs, forcing users to print and handwrite information. This often results in illegible entries that the court clerk cannot process, leading to rejection. To prevent this, it's best to use a tool that can convert the document into a fillable format. Services like Instafill.ai can make any PDF form fillable, allowing you to type directly into the fields for clear, legible, and professional-looking submissions.
Confusing Plaintiff/Petitioner with Defendant/Respondent
It is common for filers to accidentally switch the names of the plaintiff and defendant, especially if they are the defendant filling out the form. This creates confusion and can lead to the document being rejected for incorrect captioning. The names must be copied exactly as they appear on the initial complaint or petition. Using a tool that saves case party information can prevent this by auto-populating the names correctly on all subsequent forms.
Incorrectly Identifying the Declarant's Role
The form provides checkboxes to identify whether the declarant is the Plaintiff, Defendant, Petitioner, Respondent, or 'Other'. Failing to check the correct box or leaving it blank makes it unclear who is providing the testimony. This can weaken the statement's context and impact. Always check the box that accurately reflects your role in the case as listed in the case caption.
Providing Incomplete 'Attorney or Party' Contact Information
The top-left box requires complete contact information, including name, address, and phone number. Attorneys must also include their State Bar number. Leaving any of this information blank can lead to filing rejections, as the court needs to know who filed the document and how to contact them. Ensure every line in this section is filled out accurately.
Writing Arguments or Opinions Instead of Facts
A declaration's purpose is to present facts based on the declarant's personal knowledge, not to make legal arguments or state opinions. The body of the declaration should contain a numbered list of factual statements (e.g., 'On May 1, 2023, I saw...'). Including arguments or speculation can undermine the credibility of the declaration and may lead to parts of it being disregarded by the judge. Focus only on what you know to be true from your own experience.

Who needs to fill out this form?

This large space is for your factual statement. You should write down all the relevant facts you want the court to consider, usually organized in numbered paragraphs for clarity.
What do I do if I don't have an attorney?
