FL-117 – Notice and Acknowledgment of Receipt
Request DocumentJurisdiction: Country: United States | Province or State: California
The FL-117 – Notice and Acknowledgment of Receipt is a family law form used in California to confirm that court papers were delivered and received by mail. It plays a specific role in the process of formally notifying someone about a family law case. If you are starting or responding to a case, this document may be part of your paperwork.
This form is commonly used when one party agrees to accept service by mail instead of being personally handed documents by a process server. It helps document that the receiving party actually got the papers. That confirmation can affect court deadlines and next steps in your case.
If you are filling out forms for divorce, legal separation, parentage, or custody, you may see this document included in your packet. Understanding how it works can help you avoid delays or confusion about whether the service was completed properly.
The FL-117 – Notice and Acknowledgment of Receipt does not start a case by itself. It does not ask the court to make a decision. Instead, it confirms that the required documents were received in a legally recognized way.
What is FL-117 – Notice and Acknowledgment of Receipt?
Clear definition
FL-117 – Notice and Acknowledgment of Receipt is a written acknowledgment that court documents were received by mail. It is used in California family law cases to show proof of service.
“Service” means officially delivering legal documents to the other party in a case. Courts require proof that each side has received certain filings. This form creates a record that the recipient got the documents and agrees that service by mail was acceptable.
The form is signed by the person who receives the documents, not by the person who mailed them. Once signed and returned, it can be filed with the court as evidence that service was completed.
Who typically uses this form?
This form is commonly used by spouses, domestic partners, or parents involved in family law cases. It may be used in divorce, legal separation, nullity, parentage, and certain custody or support matters.
The person starting the case often includes this form in the initial mailing to the other party. The receiving party reviews the documents and, if willing, signs the acknowledgment.
It is often used when both parties are communicating, and there is no dispute about receiving the paperwork. It can reduce the need for personal service by a third party.
Self-represented individuals frequently use this form because it is included in standard family law filing packets. Attorneys may also use it when appropriate.
Why might you need this form?
Courts require proof that the other party was properly notified of a case. Without a valid service, the court may not move forward. This form provides one way to prove that notice was given.
Using this document can simplify the service process. Instead of arranging in-person delivery, the documents are mailed along with the acknowledgment form. If signed and returned, service is considered complete as of the date of signing.
It can also reduce costs. Personal service may involve paying a process server or coordinating delivery. Mail service with acknowledgment may be less expensive if the other party cooperates.
This form also creates a clear timeline. Once signed, it establishes when the recipient officially received the documents. That date can affect response deadlines.
Typical real-life scenarios
- You file a petition for divorce and want to serve your spouse. You mail the petition, summons, and FL-117 – Notice and Acknowledgment of Receipt. Your spouse signs and returns the acknowledgment, confirming receipt.
- You and the other parent agree on many issues and are communicating. Instead of arranging personal delivery, you use a mail service with acknowledgment to handle the required paperwork formally.
- You live in a different city from the other party. Coordinating in-person service is difficult. You send the documents by mail with the acknowledgment form to simplify the process.
- You are responding to a case and receive documents in the mail along with the acknowledgment form. By signing, you confirm that you received the papers and understand that deadlines may begin from that date.
When would you use FL-117 – Notice and Acknowledgment of Receipt?
You would typically use this form when you are serving initial family law documents by mail, and the other party is willing to accept them. It is most often used at the beginning of a case, when a petition and summons must be formally delivered.
The person who files the petition includes the acknowledgment form with the mailed documents. The receiving party reviews everything and decides whether to sign. If signed and returned, the filing party can submit it to the court as proof of service.
This form is often used when both parties are cooperating or at least communicating. If there is conflict or avoidance, personal service may be used instead. The acknowledgment method depends on the recipient’s participation.
It may also be used in certain post-judgment situations where documents must be served, and the receiving party agrees to accept service by mail. The exact availability can vary depending on the type of filing and stage of the case.
Both self-represented parties and those with attorneys may use this method. The key element is that the recipient signs the acknowledgment confirming receipt of the specific documents listed.
Legal characteristics of FL-117 – Notice and Acknowledgment of Receipt
This form becomes effective when the recipient signs and dates it, acknowledging receipt of the listed documents. The signature confirms that the person received the papers and accepts service by mail.
For the acknowledgment to work properly, the correct documents must be listed on the form. If the description is unclear or incomplete, it may cause confusion about what was actually served. Accuracy matters.
The date of signing is important. In many situations, response deadlines are calculated from the date the acknowledgment is signed, not the date the documents were mailed. This can affect how much time the recipient has to respond.
Common problems include failing to include all required documents, not obtaining a signature, or not filing the signed acknowledgment with the court. If the form is never signed, service by mail through this method may not be valid.
This document does not replace the need to follow other procedural rules. It does not grant the court authority by itself. Proper service is one part of establishing the court’s ability to proceed with the case.
California family law procedures are specific about how initial papers are served. This form is designed to meet those requirements when used correctly, but only within the types of cases and documents where mail service with acknowledgment is allowed.
Is it legally binding?
Yes, in the sense that once the recipient signs the acknowledgment, it serves as legally recognized proof that the documents were received. The signature confirms acceptance of service by mail for the listed papers.
By signing, the recipient is not agreeing with the contents of the documents. They are only confirming receipt. The acknowledgment does not mean they admit anything in the petition or waive their right to respond.
After the signed form is filed, the court may treat service as complete. That means deadlines for filing a response or other documents may begin running from the date of signing.
If the recipient signs under pressure or without understanding what they are signing, that could raise separate issues. However, the form itself is intended as a straightforward confirmation of receipt, not a settlement or agreement about the case.
How to fill out FL-117 – Notice and Acknowledgment of Receipt
Step 1 – Review the case information at the top of the form
Start by looking at the case caption. This section includes the court name, location, case number, and names of the parties. Make sure the information matches the related petition and summons. If you are preparing the form to send, confirm that the case number is correct before mailing.
Step 2 – Identify the documents being served
The form includes a section where the specific documents are listed. Carefully enter the full name of each document included in the mailing. Use the exact titles as they appear on the forms. This ensures there is no confusion about what was received.
Step 3 – Provide the mailing details
Enter the date the documents were mailed and the address where they were sent. Accuracy is important. The address should match the recipient’s current mailing address to avoid disputes about delivery.
Step 4 – The recipient reviews the documents
The receiving party reads through the documents that were mailed. This is the point where they confirm that all listed papers were actually included. If something is missing, the acknowledgment may not reflect what was received.
Step 5 – The recipient signs and dates the acknowledgment
If the recipient agrees to accept service by mail, they sign and date the form in the designated section. The signature confirms receipt of the listed documents. The date written next to the signature becomes important for calculating deadlines.
Step 6 – Return the signed form
After signing, the recipient sends the completed form back to the sender. This is usually done by mail. Keeping a copy for personal records helps maintain a clear paper trail.
Step 7 – File the signed acknowledgment with the court
Once the sender receives the signed form, it is filed with the court clerk. Filing makes the acknowledgment part of the official court record. At that point, service by mail through this method is generally considered complete.
End of steps.
Legal terms you might encounter in FL-117 – Notice and Acknowledgment of Receipt
- Service by Mail: This is the method used to deliver court papers through the postal system instead of in person. In this form, it means the documents were mailed to you, and you are confirming that you received them. It does not mean you agree with what the documents say. It only confirms delivery.
- Personal Service: This refers to the hand-delivery of court documents directly to the person being served. This form is an alternative to personal service. By signing it, the receiving party avoids the need for someone to physically deliver the documents.
- Acknowledgment of Receipt: This is the core purpose of the document. It is your written confirmation that you received specific court papers listed on the form. The acknowledgment creates a record for the court showing that service was completed.
- Summons: A summons is an official notice from the court that a legal case has been started. It tells you that you are required to respond within a certain time. If the summons is listed on this form, signing confirms you received it.
- Petition: A petition is the document that starts a family law case. It explains what the filing party is asking the court to decide. If the petition is included in the mailing, it must be clearly identified on this document.
- Proof of Service: This is evidence filed with the court showing that legal documents were delivered properly. Once signed and returned, this form becomes part of the proof of service in the case.
- Respondent: The respondent is the person who did not start the case but must respond to it. If you are the respondent, you are usually the one being asked to sign this document to confirm receipt.
- Petitioner: The petitioner is the person who started the case by filing the initial paperwork. The petitioner typically mails the documents and includes this form so the respondent can acknowledge receipt.
- Date of Service: This is the date the documents were mailed. It matters because court deadlines are often calculated from the date of service. You should check that this date matches when the documents were actually sent.
- Declaration: A declaration is a written statement signed under penalty of perjury. When you sign this form, you are declaring that you received the listed documents. That makes your signature legally significant.
FAQs
Do I have to sign FL-117 – Notice and Acknowledgment of Receipt?
You are not forced to sign this document. However, if you do not sign and return it, the other party may choose personal service instead. That can mean a process server or another adult will hand-deliver the documents to you, which may involve additional costs and delay.
What exactly am I confirming when I sign this form?
You are confirming that you received the specific documents listed on the form. You are not agreeing with the claims in those documents. Before signing, check the list carefully and make sure every item named in the document matches what you actually received in the envelope.
What if the documents listed are not the ones I received?
Do not sign the document if the list does not match what was in the mailing. Signing would confirm receipt of papers you may not have. Contact the sender and clarify the discrepancy so the list can be corrected before you consider signing.
When does my deadline to respond start?
Your response deadline usually starts from the date you were served. If you sign and return the acknowledgment, the service date typically relates to the mailing date shown on the form. Review that date carefully so you can calculate your response time accurately.
Can I change or add anything to this document before signing?
You should not alter the document unless you fully understand the impact. Changing dates, crossing out listed documents, or adding notes may cause the court to reject it. If something is incorrect, it is better to request a corrected version before signing.
What happens after I return the signed form?
Once you return it, the sender files it with the court as proof that service was completed. The court then treats you as officially served. This means your obligation to file a response moves forward based on the service date recorded.
Does signing this document mean I agree with the divorce or custody request?
No. Signing only confirms receipt of the papers. It does not mean you consent to any requests in the petition or summons. You still have the right to respond and present your position to the court.
What if I lost the envelope or do not remember the mailing date?
Check the form for the mailing date listed by the sender. That is the date typically used for court calculations. If you genuinely believe the date is incorrect, address that issue before signing so the record accurately reflects when you received the documents.

Common mistakes to avoid with FL-117 – Notice and Acknowledgment of Receipt
- Mistake: Signing without checking the list of documents, often because you assume everything is included, which can confirm receipt of papers you never received and create deadline confusion—do not forget to compare the list with the actual contents of the envelope.
