What this form asks for

The AI fills all of it, from your answers or your documents.

Form UD-116 is a legal document used in California Superior Courts for unlawful detainer (eviction) lawsuits. A plaintiff (landlord) files this declaration to ask the court for a default judgment against a defendant (tenant) who has not filed a response to the eviction complaint, providing the judge with a sworn statement of the facts, including details about the rental agreement, notices served, and the amount of money owed. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

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

Validates Case Number Presence and Format

This check ensures that the 'CASE NUMBER' field is not empty and conforms to the court's expected format. A valid case number is essential for correctly filing the document and associating it with the proper legal action. If the case number is missing or incorrectly formatted, the document will be rejected by the court clerk, causing delays in the judgment process.

Ensures Declarant Role is Specified if 'Other'

This validation checks that if the box for 'other' is selected in item 1b(4), the corresponding text field specifying the declarant's role is filled out. This is important for establishing the declarant's legal standing and authority to make the declaration. Failure to specify the role can lead to the declaration being deemed invalid by the court.

Verifies Agreement Date is in the Past

This check ensures the date entered in item 4a, for when the rental agreement was made, is a valid date that occurs before the current date. An agreement date in the future is a logical impossibility and would invalidate the basis of the claim. This prevents data entry errors and ensures the timeline of events is legally coherent.

Validates Completeness of Rent Change Information

If item 5b, 'Change in rent amount,' is checked, this validation ensures that the 'from' rent, 'to' rent, and the effective date fields are all completed. Incomplete information about a rent change would make it impossible to verify the correct amount of rent due. This check is crucial for accurately calculating past-due rent and justifying the amount claimed.

Confirms Rent Demand Details for 3-Day Notice

This check verifies that if '3-day notice to pay rent or quit' (item 6a(1)) is selected, then the amount of rent demanded and the corresponding rental period start and end dates in item 6b are all filled. These details are the foundation of a non-payment eviction case. Missing this information would render the default judgment request defective and likely to be rejected.

Ensures Logical Rental Period in Notice

This validation confirms that for the rental period specified in item 6b, the 'beginning on' date is chronologically before the 'ending on' date. An inverted or illogical date range would invalidate the notice and the claim for rent for that period. This check prevents simple but critical data entry errors.

Common Mistakes in Completing UD-116

The ones the AI is built to catch.

Inconsistent Header Information Across Pages
Users often meticulously fill out the header on the first page but forget to repeat the Plaintiff, Defendant, and Case Number on pages 2 and 3. This happens because it feels repetitive, but each page is a distinct part of the court filing. An incomplete header on any page can lead to the document being rejected by the court clerk, causing delays in obtaining the default judgment.
Mismatching Rent Demand in Notice
A critical error is entering a rent amount in Section 6b that does not exactly match the amount demanded on the attached 3-day notice to pay rent or quit. Even a one-cent discrepancy can invalidate the entire unlawful detainer action, as the law requires the notice to be precise. This mistake often occurs from typos or failing to double-check the source document before filling out the form.
Failure to Attach Mandatory Exhibits
The form explicitly states that the Notice to Quit (Exhibit 6d) and its Proof of Service (Exhibit 8b) MUST be attached if not already filed with the complaint. People often overlook this, assuming the court already has the documents. Failure to attach these required exhibits will result in an immediate rejection of the declaration, halting the judgment process until the packet is resubmitted correctly.
Miscalculating Holdover Damages
Calculating holdover damages in Section 12 involves correctly identifying start and end dates and performing accurate multiplication. Common errors include miscounting the number of days or using the wrong daily rental value from Section 10. These mathematical errors lead to an incorrect judgment amount, which the court may reject or reduce, requiring an amended filing.
Incorrect Notice Expiration Date Calculation
In Section 9, filers often miscalculate the date the notice expired by not correctly applying legal rules for counting days, which exclude the day of service and may extend for weekends or holidays. An incorrect expiration date can render the entire action premature and legally defective. This can be a basis for the defendant to challenge the judgment later.
Mathematical Errors in Final Judgment Summary
Section 15 requires adding up past-due rent, damages, fees, and costs to arrive at a total judgment. Simple arithmetic errors are common, where the sum in line 15a(6) does not match the total of the individual amounts listed above it. A court clerk will likely catch this inconsistency and reject the filing, delaying the entry of judgment.
Incomplete or Vague Property Address
Filers sometimes provide an incomplete property address in Section 2, such as omitting an apartment or unit number, or failing to list the county. This creates legal ambiguity about the specific premises subject to the eviction order. An imprecise address can make the resulting judgment unenforceable and cause significant issues for the Sheriff when attempting to execute the writ of possession.
Forgetting Signature and Date
Submitting an unsigned or undated declaration is a frequent and fatal mistake. The signature and date under penalty of perjury are what give the document its legal force. An unsigned form is legally worthless and will be rejected outright by the court, causing significant and unnecessary delays.
Improperly Documenting Rent Changes
When the rent has changed, filers often fail to properly complete Section 5 by not attaching the required notice of change in terms (Exhibit 5d) or not using the separate MC-025 form for a complex rent history. This omission creates a discrepancy between the rent claimed and the original agreement, which can be grounds for the court to deny the requested rent and damages. AI-powered tools like Instafill.ai can help by prompting users for necessary attachments based on their checkbox selections.
Improperly Requesting Attorney Fees
A user may request attorney fees in Section 13 without verifying that the rental agreement contains a specific clause authorizing them. Requesting fees not supported by the contract can lead to the court striking that portion of the judgment. It is crucial to review the lease and cite the specific paragraph number that permits the recovery of fees.
Failing to Cross-Reference Attached Exhibits
The form requires checking boxes to indicate how documents like the rental agreement (Section 4) or notice (Section 6) are attached. Users often forget to check the correct box (e.g., 'to this declaration, labeled Exhibit 6d') or fail to label the physical attachments accordingly. This disorganization can confuse the court clerk and judge, potentially leading to rejection or delays while they try to locate the necessary evidence in the file.

How complex is UD-116 to fill out?
UD-116 has a Form Complexity Index of 63 out of 100, in the complex tier: 150 fillable fields across 3 pages. Instafill.ai's AI fills it in under a minute, with every field there for you to review before you download.
What is the purpose of the UD-116 form?
This form is a declaration used by a landlord in an eviction (unlawful detainer) lawsuit to ask the court for a default judgment. It is filed when the tenant has not responded to the court case within the legal time limit.
Who needs to fill out and sign this form?
The form must be completed and signed by the plaintiff (landlord), property owner, property manager, or an agent of the owner who has direct personal knowledge of the rental agreement and the facts of the case.
What documents do I need to attach to this declaration?
You must attach copies of the rental agreement, the notice served to the tenant (like a 3-day notice to pay or quit), and the proof of service for that notice, unless these documents were already attached to your original complaint.
What if we only had an oral rental agreement, not a written one?
The form allows for this. In section 4, you can check the box for an 'oral' agreement and then fill in the required details, such as the date the agreement was made, the monthly rent amount, and the due date.
How do I calculate the 'fair rental value' in section 10?
The form provides two common methods: dividing the monthly rent by 30 or multiplying it by 0.03288. You can choose one of these options or specify a different valuation method if applicable.
What are 'holdover damages' and how do I calculate them in section 12?
Holdover damages are the rent owed for each day the tenant remains in the property after the notice to quit has expired. You calculate the total by multiplying the daily rental value (from section 10) by the number of days the tenant has held over.
Can I request that the tenant pay my attorney fees?
You can only request attorney fees if your written rental agreement includes a clause authorizing them for the prevailing party in a lawsuit. You must reference the specific paragraph in the agreement on the form.
What information goes into the total money judgment requested in section 15?
The total judgment is the sum of all amounts you are claiming. This includes past-due rent, holdover damages, court costs, and any authorized attorney fees.
What should I do if the tenant made a partial rent payment after I served the notice?
You must accurately account for any payments received. Section 6c is provided for you to explain any partial payments and show how you arrived at the final balance due in the notice.
Do I have to fill out this form by hand?
No, you can fill it out electronically. The form is designed to be completed on a computer before printing.

Yes, services like Instafill.ai use AI to help you accurately auto-fill form fields. This can save time and help prevent common errors.
