The AI checks your answers before you download

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

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.

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.

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.

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.

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.

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.

Common Mistakes in Completing UD-120

The ones the AI is built to catch.

Entering an Incorrect or Incomplete Case Number
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.
Improperly Filling the Attorney/Party Information
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'.
Using Inconsistent Plaintiff or Defendant Names
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.
Incorrectly Identifying the Landlord in Item 1
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.
Falsely Attesting to No Rental Assistance in Item 2
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.
Omitting the Signer's Title for a Business Entity
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.
Forgetting to Date or Sign the Declaration
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.
Specifying the Incorrect Court Location or Branch
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.
Confusing the Signature and Printed Name Lines
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.
Submitting a Poorly Hand-filled or Scanned Form
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.
