Quick Answer
What is Michigan form MC 12?
Form MC 12 lets a judgment creditor garnish payments that repeat over time — most often wages, but also rent or commissions. A periodic writ in Michigan stays active for 182 days from the date it is issued.
Who files it
A creditor who already holds an unsatisfied Michigan money judgment.
Where it goes
The court that entered the judgment; the issued writ is then served on the garnishee, such as the employer.
Filing fee
$15 statutory writ fee to the court, plus a $35 garnishee processing fee paid to the employer or bank.
What you need before you start
- The case number and date of the judgment
- The current balance, including post-judgment interest and costs
- The debtor's full legal name and, where required, Social Security number
- The exact legal name and service address of the employer or other garnishee
- A filed disclosure period start date
How to complete and file form MC 12
- 1
Calculate the current balance owed including accrued interest and allowable costs.
- 2
Complete the request naming the garnishee exactly as it is legally registered.
- 3
File with the court and pay the writ fee so the clerk issues the writ.
- 4
Serve the issued writ on the garnishee along with the $35 fee, and serve a copy on the debtor.
- 5
Wait for the garnishee's disclosure, which is due within 14 days of service.
Mistakes that get MC 12 rejected
- Using the periodic form for a bank account, which requires the non-periodic form MC 13 instead
- Naming a store or brand name instead of the employer's registered legal entity
- Omitting the $35 garnishee fee, which lets the garnishee ignore the writ
- Letting the 182-day period lapse without filing a new writ
