Frequently Asked Questions About UD-120
UD-120 has a Form Complexity Index of 32 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 UD-120 specifically, the score reflects 24 fillable fields across 1 page. 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 UD-120 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 a sworn declaration used by a landlord in an eviction case to verify to the court that they have not received or applied for rental assistance for the rent being claimed in the lawsuit.
The plaintiff (landlord) or their attorney must complete and file this form in an unlawful detainer (eviction) case that is based on the nonpayment of rent for a residential property.
This form is mandatory whenever you, as the landlord, request a default judgment against a tenant for nonpayment of rent. A judicial officer may also order you to file it at other times during the case.
You will need your court case information, including the case number, court name, and the names of the plaintiff and defendant. You must also know the status of any rental assistance you may have applied for or received.
You are declaring under penalty of perjury that you have not received any rental assistance for the amount demanded in the complaint, nor do you have any pending applications for such assistance.
If you have a pending application for rental assistance, you cannot truthfully sign this form. The statements in section 2 require you to confirm that you do not have any pending applications for the rent at issue.
The court will likely reject your request for a default judgment. Filing this form is a mandatory step to proceed with a default judgment in residential nonpayment cases.
The landlord (plaintiff) or their attorney must sign the form. If you are signing on behalf of a corporation or business entity, you must also provide your title.
You must file the completed and signed form with the clerk of the superior court where your unlawful detainer case was filed. It should be submitted along with your request for default judgment.

Validation Checks by Instafill.ai
1
Validate Case Number Format
Verifies the Case Number field is populated and follows a format typical for California court cases. The case number is the primary identifier for the legal action, and an incorrect or missing number will cause the document to be rejected by the court clerk or misfiled. This check ensures the document can be correctly associated with its corresponding case file.
2
Conditional State Bar Number Requirement
Ensures that if the 'ATTORNEY FOR' field is filled, the 'STATE BAR NUMBER' field is also populated. For attorneys filing on behalf of a client, providing a valid State Bar Number is mandatory to prove they are licensed to practice. Failure to provide this number when required will result in the filing being rejected.
3
Consistency Check: Attorney For and Plaintiff
Validates that the name listed in the 'ATTORNEY FOR (name)' field is the same as the name in the 'PLAINTIFF' field. This check confirms that the person filing the form is legally representing the plaintiff in the case. A mismatch indicates a critical error that could invalidate the filing and requires correction before submission.
4
Consistency Check: Landlord and Plaintiff Name
Ensures the landlord's name entered in Item 1 matches the name listed for the 'PLAINTIFF' in the case caption. In an unlawful detainer action, the plaintiff is the landlord, so these names must be identical for the declaration to be valid. A discrepancy can lead to legal challenges and the rejection of the verification by the court.
5
Mandatory Plaintiff and Defendant Names
Checks that both the 'PLAINTIFF' and 'DEFENDANT' fields are filled out in the case caption. These names identify the parties involved in the lawsuit and are essential for the document's legal context. A form submitted without identifying both parties is fundamentally incomplete and will be rejected.
6
Mandatory Landlord Name in Item 1
Verifies that the text field for Item 1, which identifies the landlord, is not empty. The entire purpose of this form is for the landlord to make a specific declaration. Failing to name the landlord in this section makes the declaration legally meaningless and will result in the form being deemed insufficient.
7
Completeness of Signature Block
Confirms that the 'Date' and 'TYPE OR PRINT NAME' fields under the declaration are both completed. A declaration made under penalty of perjury is legally invalid without a date and the printed name of the signatory. An incomplete signature block will cause the court to reject the entire document.
8
Validate Signature Date Format and Logic
Checks that the 'Date' in the signature block is a valid date in a recognized format (e.g., MM/DD/YYYY) and is not a future date. The date establishes when the sworn statement was made, which is critical for legal purposes. An invalid, nonsensical, or future date would invalidate the declaration.
9
Completeness of Filer's Address
Verifies that if the 'NAME' field for the attorney or party is filled, the 'STREET ADDRESS', 'CITY', 'STATE', and 'ZIP CODE' fields are also completed. Court rules require a complete mailing address for service of documents and official communication. An incomplete address can lead to filing rejection or critical missed legal notices.
10
Mandatory Court County
Ensures that the 'COUNTY OF' field under the Superior Court heading is populated. This specifies the legal jurisdiction for the case and is a fundamental requirement for any court filing. A document without the county specified cannot be routed to the correct courthouse and will be rejected immediately.
11
Validate Telephone Number Format
Checks that the 'TELEPHONE NO.' field, if filled, contains a number in a valid format (e.g., 10 digits, possibly with dashes or parentheses). This ensures the court and opposing parties have a functional contact number for the filer. An improperly formatted number can hinder communication and cause procedural delays.
12
Validate Email Address Format
Verifies that if an email address is provided in the 'EMAIL ADDRESS' field, it conforms to the standard '[email protected]' format. Correct email formatting is crucial for successful electronic communication and service of documents. An invalid format could lead to failed deliveries of important legal notices.
13
Validate ZIP Code Format
Ensures the 'ZIP CODE' field contains a valid 5-digit or 9-digit (ZIP+4) numeric format. A valid ZIP code is essential for the timely and accurate delivery of mailed court documents. An incorrect format can lead to returned mail and missed deadlines.
Common Mistakes in Completing UD-120
Filers often mistype the case number or leave it blank, especially when handling multiple documents. The case number is the court's primary identifier for the legal action; an error can lead to the document being misfiled or rejected by the clerk. This causes significant delays in the unlawful detainer process, particularly in obtaining a default judgment. To prevent this, always double-check the case number against the initial complaint or other official court documents before filing.
Self-represented landlords (acting 'in pro per') frequently get confused by the header section designed for attorneys. They may leave it blank or fill it out incorrectly, not realizing they must enter their own name, address, and contact information. An incomplete or incorrect header can lead to rejection by the court clerk or missed communications. If you are self-represented, you must fill this section with your own information and list your name after 'ATTORNEY FOR'.
The plaintiff and defendant names on this form must match exactly how they appear on the original Summons and Complaint. People often use abbreviations, nicknames, or forget to include all named parties, which creates legal discrepancies and potential grounds for the filing to be challenged. Always refer to the initial court filings and copy the names precisely to ensure the document is legally consistent with the rest of the case file.
The name in Item 1 must be the legal name of the landlord who is the plaintiff, not a property manager or agent unless they are the actual owner and plaintiff. If the property is owned by an LLC or corporation, that full legal name must be used. This mistake occurs due to confusion between legal ownership and management, and it can invalidate the verification, as the declaration must be made by the actual party of interest.
This is the most critical mistake with severe consequences. A landlord might sign the form without realizing that a pending application with a local charity, or a partial payment received from a government program, counts as 'rental assistance or other financial compensation.' Signing this form falsely constitutes perjury, which carries legal penalties and can cause the entire eviction case to be dismissed. Before signing, a landlord must meticulously review all financial records and communications to confirm no funds have been received and no applications are pending from any source.
When the landlord is a corporation, LLC, or other business entity, the individual signing the form must provide their title (e.g., 'President,' 'Managing Member'). This title demonstrates their legal authority to sign on behalf of the company. Forgetting the title can lead the court to question the validity of the declaration, causing delays or rejection of the filing. The signer must be an authorized person, and their title clarifies that authority.
An unsigned or undated declaration is invalid and will be immediately rejected by the court, halting the legal process. In the rush to complete paperwork, filers frequently overlook the date and signature fields at the bottom of the form. A declaration under penalty of perjury is incomplete without a signature and the date it was signed, so always perform a final check of these fields before submission.
California's Superior Court system is divided by county and often has multiple branches. Filers may list the main county courthouse when the case is actually heard at a specific regional branch, or they might copy an address from a different case. Filing a document with the wrong court information can cause it to be lost or significantly delayed in reaching the correct department. The correct street address, mailing address, and branch name from the original complaint must be used.
It is a common data entry error for people to write their signature on the 'TYPE OR PRINT NAME' line and then print their name where the signature should go. This happens due to haste or not reading the field labels carefully. While sometimes overlooked, it is technically incorrect and can be grounds for rejection, as the signature is a unique legal mark and the printed name is for legibility. Using a guided form-filling tool can help prevent this by clearly delineating input fields.
Court forms are often available as non-fillable PDFs, leading people to print and hand-write them. This can result in illegible entries, which may cause the court clerk to reject the form or misinterpret crucial information like names or case numbers. To ensure clarity and professionalism, it is best to use a tool to create a clean, typed document. AI-powered tools like Instafill.ai can convert a flat PDF into a fillable version, ensuring all entries are typed, legible, and properly formatted for submission.
