Jurisdiction: Country: United States | Province or State: California

The MC-012 – Memorandum of Costs After Judgment, Acknowledgment of Credit, and Declaration of Accrued Interest is a court form used after a judgment has already been entered in a civil case. It helps you update the court and the other side about additional costs, payments received, and interest that has built up on the judgment.

If you won a money judgment, this form allows you to claim certain allowed costs and calculate ongoing interest. If you have received payments, you also use it to formally acknowledge those credits. It creates a clear, written record of what is still owed.

You may be looking at this form because you are trying to collect on a judgment. Or you may have received it from the other side and want to understand what it means. Either way, this document plays an important role in post-judgment collection.

Filling it out carefully matters. Errors in calculations or missing information can cause delays or disputes. Understanding what the form does will help you complete it with confidence.

What is MC-012 – Memorandum of Costs After Judgment, Acknowledgment of Credit, and Declaration of Accrued Interest?

Clear definition

MC-012 – Memorandum of Costs After Judgment, Acknowledgment of Credit, and Declaration of Accrued Interest is a post-judgment court filing used to update the amount owed on a judgment. It lists additional recoverable costs, payments received from the debtor, and interest that has accrued since the judgment was entered.

It does not create a new judgment. Instead, it builds on an existing one. It adjusts the total balance to reflect lawful collection costs, credits, and accumulated interest.

The form becomes part of the court record once filed. It gives formal notice to the other party of the updated amount being claimed.

Who typically uses this form?

This form is commonly used by a judgment creditor. That is the person or business that won a money judgment in court and is trying to collect it.

Sometimes an attorney prepares and files the form. In other cases, a self-represented person completes it without a lawyer.

The judgment debtor, meaning the person who owes the money, may review this form after receiving it. While they do not usually prepare it, they need to understand it because it affects the claimed balance.

Why might you need this form?

After a judgment is entered, collection efforts can involve additional expenses. These may include fees for issuing writs, serving documents, or conducting certain enforcement procedures.

Interest also continues to accrue on most money judgments until the balance is paid in full. Over time, that interest can significantly increase the total owed.

If you receive partial payments, you must credit them properly. This form allows you to document those credits and show how they reduce the outstanding balance.

Without this filing, there may be confusion about what is still owed. The form provides a structured way to present the updated numbers.

Typical real-life scenarios

• You win a civil case for unpaid services. Months later, you begin collection efforts and pay fees to the court and a process server. You use this form to add those allowable costs to the judgment amount.
• You obtain a writ of execution to levy a bank account. The court charges a fee for issuing the writ. You include that fee in the memorandum, so the total reflects what you spent to enforce the judgment.
• The debtor makes two partial payments over several months. You use the acknowledgment of credit section to show exactly how much was paid and on what dates. This keeps the record accurate.
• Interest has been accruing since the judgment date. You calculate the interest to the present date and declare the total on the form, so the updated balance is clear.

When would you use MC-012 – Memorandum of Costs After Judgment, Acknowledgment of Credit, and Declaration of Accrued Interest?

You use this form after a money judgment has already been entered by the court. It is not used during the trial phase or before judgment.

It is commonly used before or during active collection efforts. For example, you may file it before requesting a writ of execution or taking other enforcement steps. The updated total helps support the amount you are seeking to collect.

If you have incurred new, allowable costs related to enforcement, this form may be used to claim them. It gives the other party formal notice of those additional amounts.

You may also use it when you have received payments and want the court record to reflect those credits. This can be important when calculating the remaining balance or when future enforcement actions are based on that amount.

In many cases, the judgment creditor files the form periodically as costs and interest accumulate. The timing can depend on how the collection is progressing and whether new expenses have been added.

Legal characteristics of MC-012 – Memorandum of Costs After Judgment, Acknowledgment of Credit, and Declaration of Accrued Interest

This form operates within an existing judgment. It does not reopen the case or change who won. Instead, it updates the financial details tied to the judgment.

For the filing to be effective, it must generally be completed accurately and served on the judgment debtor. Proper service ensures the other party has notice of the claimed costs and interest.

Courts may reject the form if required sections are left blank, calculations are inconsistent, or signatures are missing. Mathematical errors are a common issue. Even small mistakes can lead to disputes or delays.

Not all expenses are recoverable. Only certain types of post-judgment costs are typically allowed. Claiming items that are not permitted can lead to objections from the debtor.

There may be procedural differences depending on the type of case, such as limited or unlimited civil matters. Filing requirements and timing may vary slightly depending on the court and case category.

This form does not automatically collect money for you. It does not seize property or garnish wages by itself. It simply updates the amount you are asserting is owed under the judgment.

Is it legally binding?

When properly completed and filed, the information in the form becomes part of the court record. The declaration section is signed under penalty of perjury, which gives it legal weight.

The acknowledgment of credit is especially significant. It formally recognizes payments received and reduces the claimed balance. Once declared, it represents your official statement of the amounts credited.

However, the form itself does not create a new court order. The original judgment remains the controlling order. The memorandum adjusts the total being claimed under that judgment.

If the debtor disagrees with the claimed costs or interest, there may be procedures to challenge them. Until challenged or corrected, the filed amounts are generally treated as the updated total for enforcement purposes.

How to fill out MC-012 – Memorandum of Costs After Judgment, Acknowledgment of Credit, and Declaration of Accrued Interest

Step 1 – Fill in the court and case information

At the top of the form, enter the name of the court, the court address, and the case number exactly as they appear on the judgment. List the names of the judgment creditor and judgment debtor as shown in the original case. Make sure the case number matches the judgment to avoid processing delays.

Step 2 – Identify the judgment creditor

In the section asking who is claiming costs, enter your name if you are the judgment creditor. If you are completing the form on behalf of a business or another person, use the same name that appears on the judgment. Consistency with the original judgment is important.

Step 3 – Enter post-judgment costs

In the costs section, list each allowable post-judgment cost in the appropriate line. Enter the amount for each item and calculate the total. Use clear, accurate figures. Double-check your math before moving to the next section.

Step 4 – Acknowledge credits for payments received

In the acknowledgment of credit section, enter the total amount of any payments received from the judgment debtor. Include payments made directly to you or through enforcement actions. This amount will reduce the balance owed.

Step 5 – Calculate accrued interest

Determine the amount of interest that has accrued on the unpaid judgment principal. Enter the calculated interest in the space provided. Make sure the time period used for the calculation is consistent with the judgment date and any payments received.

Step 6 – Determine the total amount now due

Add the original judgment amount, allowable costs, and accrued interest. Then subtract any credits for payments received. Enter the final total in the space provided as the updated amount due. Review each number carefully to confirm accuracy.

Step 7 – Complete the declaration and sign

Read the declaration statement at the end of the form. By signing, you are stating under penalty of perjury that the information is true and correct. Sign and date the form where indicated. If you are an attorney, include your information as required in the signature area.
