Frequently Asked Questions About MC-010
MC-010 has a Form Complexity Index of 41 out of 100, placing it in the basic complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.
For MC-010 specifically, the score reflects 64 fillable fields across 2 pages. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.
In practical terms, a basic score means the form is relatively light, but still needs careful, accurate entry. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes MC-010 accurately in under a minute, with every field available for you to review before you download. See exactly how the Form Complexity Index is calculated.
This form is used by the prevailing party in a California lawsuit to request reimbursement for the allowable costs they incurred during the case. It serves as a summary of expenses being claimed from the losing party.
The winning party in a civil case, or their attorney, must fill out this form if they wish to recover their litigation costs. It is filed with the court and served on the opposing party after a judgment or dismissal has been entered.
You will need your case information (court name, case number, party names), a detailed breakdown of all costs you are claiming, and the name and address of the opposing party for the Proof of Service.
You can only list attorney fees on line 10 if the amount is fixed by a contract or statute and does not require a court's decision. In most other situations, you must file a separate noticed motion to ask the court to determine the amount of attorney fees.
The Proof of Service is a required declaration stating that a copy of the Memorandum of Costs was properly delivered to the other party. It must be completed and signed by someone who is over 18 and not a party in the case.
After signing the form, you must file the original with the court clerk and serve a copy on the opposing party. The person who serves the copy must then complete and sign the Proof of Service on page 2 of the copy you file with the court.
Yes, you must file and serve this form within 15 days after the notice of entry of judgment is mailed, or within 180 days after the judgment is entered, whichever is earlier. It is crucial to check the specific rules and deadlines for your case.
The opposing party has a right to object by filing a 'Motion to Tax Costs' with the court. If they do, a judge will decide which of your claimed costs are reasonable and necessary.
No, you do not need to attach documentation when you initially file the form. However, you must keep all receipts and invoices, as you will need to provide them as proof if the other party challenges your costs.
The 'Other' category is for any allowable costs that are not specifically listed in items 1-14, such as certain travel expenses or other costs permitted by law. Be prepared to provide a detailed explanation and justification for these items if asked.

Compliance MC-010
Validation Checks by Instafill.ai
1
Total Costs Calculation Accuracy
Verifies that the 'TOTAL COSTS' field is the correct sum of all individual cost items (lines 1-15). This is a critical check to ensure financial accuracy and prevent mathematical errors in the cost claim. If the sum is incorrect, the filing may be rejected or require correction, delaying the cost recovery process.
2
Case Number Consistency Across Pages
Ensures the 'CASE NUMBER' entered on Page 1 is identical to the 'CASE NUMBER' on Page 2. This validation is crucial for document integrity, linking the cost summary with its proof of service. A mismatch could lead to the proof of service being invalidated or associated with the wrong case file.
3
State Bar Number Format
Validates that the 'STATE BAR NUMBER' field contains only numeric digits. This check ensures the data quality for a key professional identifier, as an incorrect format can hinder attorney verification. If the field is filled, it must be a valid number.
4
Declarant Capacity Selection
Confirms that exactly one of the declarant capacity checkboxes ('the party', 'counsel for the party', 'agent for the party') on Page 1 is selected. This is legally significant as it specifies the authority of the person signing the declaration. Failure to select a role makes the declaration ambiguous and potentially invalid.
5
Proof of Service Method Selection
Checks that one, and only one, of the primary proof of service methods ('MAILING' or 'PERSONAL DELIVERY') is selected on Page 2. This selection determines which subsequent sections are relevant and required. An invalid or missing selection makes the proof of service incomplete and unenforceable.
6
Conditional Requirement for Mailing Details
If 'Mail' (item 3a) is chosen as the service method, this validation ensures that all related fields, including the name of the person served, address, date of mailing, and place of mailing, are completed. Omitting any of this information invalidates the proof of service by mail. This check enforces the procedural rules for proper service.
7
Conditional Requirement for Personal Delivery Details
If 'Personal delivery' (item 3b) is chosen, this check mandates that the name of the person served, delivery address, date, and time of delivery are all filled in. This information is essential for creating a legally sufficient record of personal service. Incomplete details can render the proof of service defective.
8
Uniform Date Format
Verifies that all date fields on the form (e.g., declaration dates, service dates) adhere to a valid and consistent format, such as MM/DD/YYYY. This is important for legal record-keeping and establishing timelines. Invalid date formats can cause data entry errors and create ambiguity about critical event dates.
9
Numeric-Only Cost Fields
Ensures that all individual cost amount fields (lines 1-15) only accept numeric input, including decimals for cents. This prevents non-numeric characters from being entered, which would break the total cost calculation. This validation is fundamental for maintaining the financial integrity of the document.
10
Attorney Information Completeness for Counsel
If 'counsel for the party' is checked on Page 1, this validation requires the attorney's name, State Bar number, and firm address to be filled out. This is necessary to properly identify the legal representative submitting the costs. Missing information can lead to communication issues and delays in processing the document.
11
Valid Email Address Format
Checks the 'EMAIL ADDRESS' field to ensure the entry conforms to a standard email format (e.g., '[email protected]'). This is important for ensuring that electronic communications and notifications from the court or other parties are deliverable. An invalid email address can result in missed communications.
12
Party Identification Completeness
Validates that both the 'PLAINTIFF' and 'DEFENDANT' fields are filled out. These fields are essential for identifying the primary parties to the litigation and correctly associating the document with the case. A form missing this core information is incomplete and cannot be properly filed.
13
Proof of Service Declaration Completeness
Ensures that the declaration on Page 2 includes the server's printed name and the date of signature. These elements are required to execute a valid declaration under penalty of perjury. Omitting the name or date renders the proof of service declaration invalid.
14
Server Address Requirement
Verifies that the server's residence or business address field on Page 2 is not empty. This information is required by court rules to identify the person who performed the service and is a necessary component of a valid proof of service. An empty address field makes the proof of service defective.
Common Mistakes in Completing MC-010
Filers often manually add the individual cost items and make simple arithmetic errors, resulting in an incorrect figure in the 'TOTAL COSTS' field. This discrepancy can lead to challenges from the opposing party and may require filing an amended memorandum. To prevent this, carefully double-check your calculations or use a spreadsheet before entering the final number. AI-powered tools like Instafill.ai can perform these calculations automatically, eliminating the risk of human error.
A frequent and significant error is entering attorney fees on line 10 when a separate noticed motion is legally required. This line is strictly for fees that are fixed by contract or statute and do not require a court determination. Listing fees here improperly can result in the court striking them, forcing the filer to start over with a formal motion, which wastes time and risks missing deadlines.
Users often meticulously fill out page 1 but forget to enter the 'SHORT TITLE' and 'CASE NUMBER' at the top of page 2. If the pages are separated during processing, the Proof of Service becomes an orphan document that cannot be linked to the case file. This can invalidate the service of the cost memorandum, jeopardizing the entire claim.
The Proof of Service on page 2 must be completed and signed by someone who is at least 18 years old and not a party to the action. Parties representing themselves (pro se litigants) often make the mistake of filling out and signing this section themselves. This renders the service invalid and is a common reason for a motion to strike the cost memorandum to be granted.
Forgetting to sign or date the declaration on page 1 or the Proof of Service declaration on page 2 is a critical omission. A declaration made 'under penalty of perjury' is invalid without a signature and date. This can lead to immediate rejection by the court clerk or allow the opposing party to have the filing thrown out entirely.
The Proof of Service section is often filled out incompletely, with missing dates, addresses, or names of persons served. Another common error is checking both 'Mail' and 'Personal delivery' or filling in details for both methods. These errors create ambiguity and can be used by the opposing counsel to challenge the validity of the service, forcing a re-filing.
On page 1, directly above the signature line, there are checkboxes to indicate whether the declarant is the 'party,' 'counsel for the party,' or 'agent for the party.' It is a simple but common oversight to leave these boxes unchecked. This makes the form technically incomplete and can cause it to be rejected by the clerk for correction, delaying the filing.
Filers may enter a significant amount on line 15 for 'Other' costs without attaching a separate worksheet (like form MC-011) that itemizes and justifies these expenses. The summary form itself has no space for this explanation. Without detailed documentation, these 'Other' costs are highly likely to be disputed by the opposing party and disallowed by the court.
Data entry errors in the court information section, such as listing the wrong county, branch name, or street address, are common. This can cause the document to be misrouted or filed in the wrong courthouse, leading to significant delays and potentially missed deadlines. Verifying the precise court details from the case's prior documents is essential. AI form-filling tools like Instafill.ai can help prevent this by saving and reusing correct case information across multiple forms.
Attorneys sometimes forget to enter their State Bar Number in the caption at the top of the form. While it may seem like a minor detail, it is required information for proper identification and record-keeping by the court. A clerk may reject the filing as incomplete for this reason, requiring the attorney to add the number and refile.
