Yes! You can use AI to fill out Form CH-250, Proof of Service by Mail (CLETS) (Civil Harassment Prevention)
Form CH-250, Proof of Service by Mail, is a legal document used in California courts to declare under penalty of perjury that specific court documents in a civil harassment case have been mailed to the involved parties. It is completed by the 'server'—a person over 18 who is not a party to the case—and filed with the court to provide official proof that service was completed according to legal requirements. 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.
CH-250 is part of the

Frequently Asked Questions About CH-250
CH-250 has a Form Complexity Index of 33 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 CH-250 specifically, the score reflects 32 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 CH-250 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 to provide proof to the court that specific legal documents in a civil harassment case have been successfully mailed to the other party involved.
The 'server' must fill out and sign this form. The server is the person who actually mailed the documents, and they must be over 18 and not a party to the restraining order case.
No, you cannot serve the documents yourself if you are a party to the case. You must have a neutral third party who is at least 18 years old act as the server.
The server needs the case number, the names of the parties, the exact documents that were mailed, the name and address of the person served, and the date and location of the mailing.
After the server fills out and signs the form, you must file the original CH-250 with the court clerk. It's also wise to make a copy for your own records.
The server should check the box next to each document that was included in the envelope they mailed. Common documents include Form CH-120 (Response) or CH-130 (Restraining Order After Hearing).
The date in Section 5c is the specific date the documents were placed in the mail. The date in Section 7 is the date the server signed the form, declaring under penalty of perjury that the information is true.
No, this form is exclusively for 'service by mail'. If documents are delivered in person, a different form, such as CH-200 (Proof of Personal Service), must be used.
Yes, services like Instafill.ai use AI to accurately auto-fill form fields, which saves time and helps prevent errors. However, the server must personally review the information for accuracy and sign the form.
Simply upload the CH-250 PDF to the Instafill.ai platform. The AI will make the fields interactive, allowing you to type in all the necessary information before printing the completed form for the server's signature.
You can use a service like Instafill.ai, which can convert flat, non-fillable PDFs into interactive forms. This allows you to easily type information into the correct fields on your computer.
No, the server does not need to be a professional. They can be a friend, family member, or coworker, as long as they are over 18 and not a party to the case.

Validation Checks by Instafill.ai
1
Verifies Signature Date is On or After Mailing Date
This is a critical logical check to ensure the date the server signed the declaration (section 7) is the same day as or after the date they mailed the documents (section 5c). A server cannot truthfully declare under penalty of perjury that they mailed something before they have actually done it. An invalid date sequence would nullify the proof of service and require resubmission.
2
Ensures Server is Not a Party to the Case
This validation cross-references the server's name from section 6 against the names of the protected person (section 1) and the restrained person (section 2). The law requires the server to be a neutral third party who is not involved in the case. If the server is a party, the service is invalid and will be rejected by the court.
3
Cross-Validates Served Person's Name with Restrained Person's Name
This check compares the name of the person served (section 5a) with the name of the person to be restrained (section 2). The names should match to ensure the correct individual was served. A mismatch suggests a critical error in service, which could invalidate the proof and require the service process to be repeated.
4
Requires Specification for 'Other' Documents Served
This validation rule checks that if the 'Other' checkbox (4c) is selected, the corresponding text field describing the document is not empty. This is necessary for the court to know exactly which documents were served on the restrained person. Failure to specify the 'Other' document renders the service proof ambiguous and potentially invalid.
5
Verifies At Least One Document Was Served
This check ensures that at least one checkbox in section 4 (a, b, or c) is marked. The purpose of the form is to prove service of documents, so if no documents are indicated as served, the form is incomplete and has no legal standing. The submission would be considered invalid and rejected.
6
Validates Mailing Date Format and Plausibility
This check ensures the 'Mailed on' date in section 5c is a validly formatted date (e.g., MM/DD/YYYY) and is not a future date. Service cannot be proven for a future event. This validation prevents clerical errors and ensures the integrity of the service timeline, which is critical for legal deadlines.
7
Ensures Complete Mailing Address for Service
This validation verifies that the street address, city, state, and ZIP code fields in section 5b are all filled out. A complete and valid address is required to prove that the documents were sent to a location reasonably calculated to give notice to the restrained person. An incomplete address will lead to rejection of the proof of service.
8
Requires Complete Server Name and Address
This validation ensures the server's full name, street address, city, state, and ZIP code are provided in section 6. This information is legally required to identify the server and confirm they are a disinterested third party. Incomplete server information can invalidate the service, as the court cannot verify the server's identity or eligibility.
9
Ensures Protected and Restrained Party Names are Provided
This validation confirms that the names of both the person asking for protection (section 1) and the person being restrained (section 2) are filled in. These fields are essential for identifying the primary parties of the case. A missing name makes the document legally insufficient and will cause it to be rejected by the court clerk.
10
Validates Case Number Format
This check verifies that the Case Number field is not empty and, if possible, matches the standard format used by the specific court. An accurate case number is crucial for linking the proof of service to the correct case file in the court's system. An incorrect or missing number will cause the document to be rejected or misfiled, delaying the legal process.
11
Matches Server's Printed Name with Server Information
This check compares the server's name provided in section 6 with the printed name under the signature line in section 7. This ensures consistency and helps confirm that the person signing the declaration is the same person identified as the server. Discrepancies could indicate a potential issue with the declaration's authenticity.
12
Ensures County is Provided for Registered Process Server
This validation checks that if a process server registration number is entered in section 6, the corresponding county of registration field is also filled. The registration number is meaningless without the context of the issuing county. This is required to verify the server's professional credentials if they are acting in that capacity.
13
Validates State Fields use Standard Abbreviations
This check ensures that all state fields (for the served person, mailing location, and server) contain a valid two-letter postal abbreviation. This prevents data entry errors, ensures address accuracy for mailing and record-keeping, and standardizes the data for court systems. An invalid state code could cause processing failures.
14
Validates ZIP Code Format
This validation confirms that the ZIP codes for the served person's address and the server's address are in a valid 5-digit (NNNNN) or 9-digit (NNNNN-NNNN) format. Correct ZIP codes are essential for ensuring mail is deliverable and for the integrity of address data in the court's records. Incorrect formats will be flagged to prevent data entry errors.
Common Mistakes in Completing CH-250
A common and critical error is having the person asking for protection, or anyone else listed as a protected party in the case, mail the documents and sign this form. The form explicitly states the server must be 18 or older and not a party to the case. Using an ineligible server invalidates the proof of service, which can lead to case delays or the expiration of temporary orders because the court cannot confirm the other party was properly notified. To avoid this, service must be completed by a neutral third party, such as a friend, a relative not involved in the case, or a professional process server.
This form must be filled out and signed by the person who actually performed the service by mail (the 'server'), not the person asking for protection. It is a frequent misunderstanding where the protected person completes the form on behalf of the server. A Proof of Service form signed by a party to the case is invalid and will be rejected by the court. The server whose information is listed in Section 6 must be the same person who signs the declaration in Section 7.
The server's signature in Section 7 is what makes the document a sworn declaration; without it, the form is legally worthless. Forgetting to sign, or omitting the date of the signature, is a frequent oversight that leads to automatic rejection by the court clerk. This means there is no official record that service was completed, which can cause critical deadlines to be missed. Always double-check that the server has signed and dated the form before filing.
Filers often forget to enter the full court name and address or make typos in the case number at the top of the form. This information is essential for the court clerk to associate the Proof of Service with the correct legal file. An incorrect case number can cause the document to be rejected or misfiled, leading the court to believe service was never completed. This can be prevented by carefully cross-referencing the case number and court details from other official case documents.
In Section 4, the server must check the boxes corresponding to every document that was mailed. People frequently forget to check any boxes or fail to check all the relevant ones, making the proof of service incomplete. If the 'Other' box is checked, the specific document must be written in; leaving this blank is also an error. This omission makes the filing legally insufficient because it doesn't prove which specific orders or notices the other party received.
The 'Mailed on (date)' field in Section 5c must reflect the exact date the documents were placed in the mail. Common mistakes include using the date the form was filled out or a future date, rather than the actual date of mailing. An incorrect date can call the validity of the service into question, as legal deadlines are often calculated from the date of service. The server should fill out the form immediately after mailing the documents to ensure the date is accurate.
The names of the 'Person Asking for Protection' and the 'Person to Be Restrained' must be spelled exactly as they appear on the initial court filings, like the CH-100 Request. Using nicknames, abbreviations, or making spelling errors can create legal ambiguity and provide grounds for the opposing party to challenge the validity of the service. AI-powered form-filling tools like Instafill.ai can help prevent this by ensuring names and case details are populated consistently across all related documents.
Section 6 requires the server's full name, address, and telephone number. This section is sometimes left incomplete because the server may think their personal information is not important. However, this information is legally required to identify the server and allow the court or other parties to contact them to verify the service if needed. An incomplete Section 6 can lead to the Proof of Service being deemed invalid by the court.
The address listed in Section 5b must be the correct and current mailing address for the person being served. Using an old address, a P.O. Box that is no longer in use, or making a typo in the street name or zip code can invalidate the service. If documents are not mailed to an address where the person can reasonably be expected to receive them, the service is not proper and will not be recognized by the court, jeopardizing the entire case.
When filling out a paper copy, illegible handwriting can cause the form to be rejected. If the court clerk cannot clearly read the names, case number, addresses, or dates, the document cannot be processed correctly. This forces the filer to resubmit a legible copy, causing delays. To avoid this, it is best to print clearly in block letters or use a fillable PDF. If the form is a non-fillable PDF, tools like Instafill.ai can convert it into a fillable version to ensure all entries are clear and typed.
