What this form asks for

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

Form MC 307 is a legal document used in Michigan courts to authorize an alternative method of serving legal papers to a defendant who cannot be located for personal service. This order allows the plaintiff to notify the defendant by publishing the notice in a newspaper or posting it in designated public places, ensuring the legal case can proceed. 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

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

Ensures Case Number Consistency Across All Pages

This check verifies that the 'Case No.' entered on page 1, page 2, and page 3 are identical. Maintaining a consistent case number is crucial for linking all parts of the document correctly within the court's filing system. A mismatch could lead to the affidavits being misfiled or rejected, invalidating the service process.

Validates Defendant's Answer Deadline

This check confirms that the 'answer deadline' is a valid date and is set in the future from the date the order is signed by the judge. This is critical for due process, as it provides the defendant with a legally sufficient amount of time to respond. An invalid or past date would render the notice defective and could be grounds for dismissing a default judgment.

Verifies Judge's Signature and Date on Order

This validation confirms that the judge's signature and the date of signing are present on the first page. The judge's signature is what gives the document its legal authority as a court order. Without it, the document is merely a draft and has no legal effect, meaning any actions taken based on it are invalid.

Validates Notary Commission Expiration Date

This check confirms that the 'My commission expires on' date for each affidavit (Publishing, Posting, Mailing) is a valid date that has not yet passed. A notary cannot legally perform a notarial act with an expired commission. An expired date would invalidate the affidavit and therefore the proof of service, potentially jeopardizing the entire case.

Verifies Logical Chronology of Affidavit Dates

This validation ensures the date an affidavit is sworn ('Subscribed and sworn to before me on...') is logically consistent with the events it describes. For example, the 'Affidavit of Publishing' sworn date must be on or after the last date of publication listed. This is crucial for the affidavit's credibility, proving that the required actions were completed before the affiant swore to them.

Ensures Mutually Exclusive Duration for Publication

This validation checks the publication duration section (Item 2). It ensures that either the 'three consecutive weeks' checkbox is selected OR the 'for number of weeks' field is filled, but not both. This prevents ambiguity in the court's order regarding the required service period. If both are selected or neither is selected, the order is unclear and cannot be properly executed.

Common Mistakes in Completing MC 307

The ones the AI is built to catch.

Entering an Incorrect Case Number
The case number is the single most important identifier on this form, linking the service action to the correct court file. People often mistype this number from memory or make a transcription error when copying it. An incorrect case number can cause the document to be rejected by the clerk, filed in the wrong case, or completely invalidate the service, forcing the plaintiff to restart the process and incur additional costs. Always double-check the case number against the original complaint before filling out the form.
Providing an Incomplete or Inaccurate Last-Known Address
Section 4 requires mailing the order to the defendant's last-known address. A common mistake is using an old, incomplete, or unverified address, which undermines the purpose of the notice. This can result in the defendant successfully arguing they never received notice, potentially overturning a default judgment. It is critical to perform and document due diligence to find the most current address possible before completing this section.
Failure to Attach Required Proofs
The form explicitly requires attaching physical evidence to the affidavits: a copy of the newspaper publication (page 2) and the mailing/return receipts (page 3). Filers often forget to attach these items or provide illegible copies. Without this tangible proof, the affidavits are considered incomplete, and the court cannot verify that service was performed as ordered, leading to the rejection of the filing and significant delays.
Incomplete or Invalid Notarization
The affidavits on pages 2 and 3 are sworn statements that are legally invalid without proper notarization. Common errors include the affiant forgetting to sign in the notary's presence, or the notary failing to complete all parts of their section, such as their signature, commission expiration date, or county of commission. An improperly notarized affidavit will be rejected by the court, nullifying the proof of service and requiring the form to be re-executed.
Mismatched Information Between the Order and Affidavits
The actions described in the affidavits of publishing, posting, and mailing must perfectly match what the judge commanded in the initial order. For instance, the newspaper listed in the affidavit must be the one specified in Section 2, and the posting locations must be identical to those in Section 3. Discrepancies, which often arise from carelessness, can invalidate the service because the order was not followed exactly as written.
Ambiguous or Contradictory Service Durations
In the publication (Section 2) and posting (Section 3) sections, a user might check the box for 'three consecutive weeks' while also writing a different duration in the 'for...' field. This creates a contradiction that makes the order unclear. Performing the service for the wrong duration can make it legally defective and open to challenge by the defendant. Only one, unambiguous duration should be selected.
Vague Description of Posting Locations
Section 3 of the order and the corresponding Affidavit of Posting require specifying where the notice was posted. People often use vague descriptions like 'the courthouse' without a full address or specific location (e.g., 'the public notice board on the first floor'). This ambiguity can lead to challenges that the posting was not done in a 'conspicuous place' as required by law, potentially invalidating the service.
Incorrectly Identifying Parties
Misspelling the plaintiff's or defendant's name, using a nickname instead of a legal name, or listing an incorrect business entity are frequent errors. An incorrect party name in the header or the 'TO:' field is a critical flaw. It can be argued that the notice was not directed at the correct legal person or entity, which could invalidate the service and any subsequent judgment.
Missing or Incorrect Answer Deadline
Section 1 of the order must state a specific date by which the defendant must file an answer. This field is sometimes left blank, or the date is calculated incorrectly, creating confusion. A missing or improper deadline renders the notice defective because it fails to properly inform the defendant of their legal obligation and timeline, making the service invalid.
Using an Outdated Form Version
This form is marked 'Rev. 9/09'. Courts periodically update their forms, and submitting an outdated version can lead to automatic rejection. Filers often find old versions online or reuse forms from previous cases. It is essential to always obtain the latest version of any court form directly from the official court or state website to ensure compliance. AI-powered tools like Instafill.ai can help by using the most current, fillable versions of forms.

What is the purpose of the 'Order for Service by Publication/Posting' form?
This form is a court order used to legally notify a defendant about a lawsuit by publishing the notice in a newspaper or posting it in a public place. It is used when the defendant cannot be located for traditional in-person service.
Who needs to fill out this form?
The plaintiff (or their attorney) prepares the form for a judge's signature. After the order is signed, the newspaper publisher, the person who posts the notice, and the person who mails the documents will each need to complete and sign an affidavit on the form.
What is the difference between service by 'publication' and 'posting'?
Service by publication means the notice is printed in a newspaper for a set number of weeks. Service by posting involves displaying the notice in the courthouse and/or other specified public locations, as determined by the judge.
Why are there three different affidavits on this form?
The affidavits for Publishing, Posting, and Mailing serve as sworn proof to the court that the judge's order for alternative service was carried out correctly. Each affidavit must be completed by the person who performed the action and then notarized.
What documents do I need to attach to this form when I file it?
You must attach a copy of the actual newspaper publication to the Affidavit of Publishing. For the Affidavit of Mailing, you must attach the registered mail receipt and the return receipt as proof of mailing.
What does the deadline to 'file your answer or take other action' mean?
This is the legal deadline by which the person being sued must respond to the lawsuit. If the defendant fails to file an answer with the court by this date, a default judgment may be entered against them.
What happens after the judge signs the order?
You must arrange for the publication or posting as ordered and mail a copy to the defendant's last-known address. Afterwards, you must file the completed and notarized affidavits with the court to prove that service was completed.
What if I don't have a 'last-known address' for the defendant?
You must demonstrate to the court that you have made diligent efforts to locate the defendant. If a last-known address exists, even if outdated, the court will likely still require you to mail the documents there via registered mail.
Can AI tools help me fill out this form?

Who needs to sign this form in front of a notary public?
