The AI checks your answers before you download

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

Verifies Total Claimed Costs Calculation

This check ensures that the value in 'Total of claimed costs for current memorandum of costs' (Item 1a(9)) is the correct sum of all individual cost amounts listed in Items 1a(1) through 1a(8). This is crucial for mathematical accuracy and prevents miscalculation of claimed expenses. If the sum is incorrect, the form submission should be flagged for review, as it could lead to an incorrect judgment amount.

Ensures Total Postjudgment Costs Calculation is Correct

Validates that the 'Total of all postjudgment costs' (Item 1c) correctly equals the sum of 'Total of claimed costs for current memorandum' (Item 1a(9)) and 'All previously allowed postjudgment costs' (Item 1b). This check maintains the integrity of the total cost calculation by including both current and prior costs. A failed validation indicates a calculation error that must be corrected before filing.

Validates Credit Application Consistency

This check confirms that the sum of 'credit to accrued interest' and 'credit to judgment principal' (Item 2a) equals the 'total payments to date' amount. This is a critical logical check to ensure that all acknowledged payments are correctly allocated. If the amounts do not reconcile, the filing is inaccurate and could misrepresent the remaining balance owed.

Requires Exclusive Declarant Role Selection

Ensures that exactly one of the three checkboxes in Item 4 ('judgment creditor', 'agent for the judgment creditor', or 'attorney for the judgment creditor') is selected. This is necessary to clearly establish the identity and authority of the person signing the declaration. If zero or more than one box is checked, the declaration is ambiguous and the form should be rejected until a single, valid role is chosen.

Validates Case Number Presence and Format

This check verifies that the 'CASE NUMBER' field is not empty and, if possible, conforms to the expected format for the specified court. The case number is the primary identifier for the legal proceeding and is essential for the clerk to file the document correctly. A missing or malformed case number will result in the document being rejected or misfiled.

Checks for Valid Declaration Date

Validates that the 'Date' field in the declaration section is a valid calendar date and is not a future date. The date of the declaration is legally significant as it attests to the facts as of that day. An invalid or future date would invalidate the declaration, requiring the user to provide a current and correct date.

Common Mistakes in Completing MC-012

The ones the AI is built to catch.

Incorrect Calculation of Accrued Interest
Filers often struggle with Section 3, incorrectly calculating interest on the judgment balance. This happens because they may use the wrong interest rate, miscalculate based on partial payments, or improperly compound interest. An incorrect interest calculation is a primary reason for the opposing party to file a motion to tax costs, leading to delays and potential disallowance of the claimed interest. To avoid this, meticulously follow the steps in the MC-013-INFO guide and double-check all calculations.
Misapplication of Payments to Principal and Interest
In Section 2a, a frequent error is applying payments received from the debtor to the principal balance first. California law requires that payments are credited first to accrued postjudgment interest, with any remainder applied to the principal. This mistake understates the remaining interest due and incorrectly reduces the principal, leading to an inaccurate total balance and likely rejection or challenge. AI-powered form fillers like Instafill.ai can be configured with these rules to help automate and validate such complex calculations.
Claiming Non-Recoverable Postjudgment Costs
Users often list costs in Section 1a that are not legally recoverable, such as routine postage, faxes, or travel time. This occurs from a misunderstanding of what Code of Civil Procedure § 685.040 allows. Including unauthorized costs almost guarantees the debtor will file a motion to tax, forcing a court hearing to dispute the amounts. Always consult the MC-013-INFO information sheet to confirm a cost is allowable before including it on the memorandum.
Arithmetic Errors in Cost Totals
Simple addition mistakes in Section 1a(9) (Total of claimed costs) and Section 1c (Total of all postjudgment costs) are surprisingly common. These errors can happen due to manual calculation and can undermine the credibility of the entire document. A calculation error, even a small one, can be grounds for a successful challenge by the debtor, requiring the filer to submit a corrected form. Using a calculator or a spreadsheet to verify totals before transcribing them onto the form is a crucial step.
Missing Statutory Authority for 'Other' Costs
When claiming a cost under Section 1a(8) 'Other', filers frequently list the expense but omit the required legal justification. The form explicitly requires citing the statute that authorizes the cost. Failure to provide the specific code section makes the claim invalid on its face and will result in it being disallowed by the court. Always research and include the precise statutory basis for any cost not explicitly listed in items (1) through (7).
Incomplete or Incorrect Case Caption Information
Mistakes in the top section of the form, such as an incorrect case number, misspelling plaintiff/defendant names, or listing the wrong court branch, are common and can lead to immediate rejection by the court clerk. This often happens when filling out the form in a hurry or using information from a different case. These details must match the court's records exactly to ensure the document is filed into the correct case file. Using a tool like Instafill.ai can help by saving and accurately populating this repetitive information across all case documents.
Forgetting to Include Previously Allowed Costs
Filers often focus only on new costs and leave Section 1b, 'All previously allowed postjudgment costs,' blank. This is a significant error if prior cost memorandums have been filed and approved. Forgetting to carry over this balance results in an inaccurate and understated total amount due, which can be difficult to correct later and may result in the creditor losing out on money they are owed.
Failure to Sign or Date the Declaration
An unsigned or undated declaration in Section 4 is one of the most critical and easily avoidable errors. The signature under penalty of perjury is what makes the document a sworn statement of facts. Without a valid signature and date, the form is legally worthless and will be rejected by the court, invalidating the entire cost claim and potentially missing the filing deadline. If the form is a non-fillable PDF, a tool like Instafill.ai can convert it to a fillable version, making it easier to manage fields and avoid missing the signature line.
Incorrectly Identifying the Declarant's Role
In Section 4, filers must check a box to identify themselves as the judgment creditor, agent, or attorney. People sometimes check the wrong box, for example, an attorney might incorrectly check 'judgment creditor'. This can create legal issues regarding who has personal knowledge of the claimed costs and payments. An incorrect designation can be used by the opposing party to challenge the validity of the declaration.
Omitting Required Details for Specific Costs
Several cost categories require specific details that are often overlooked. For example, Section 1a(4) requires specifying the county where a writ of execution was issued. Failing to provide these small but necessary pieces of information can lead to that specific cost item being challenged and disallowed. Carefully read each line item to ensure all supplemental information is provided as required.
