The 30-day window has passed. Here is what to do next.
Michigan's security deposit law sets a hard 30-day return deadline under Mich. Comp. Laws § 554.602. When that deadline passes with nothing returned and no itemized statement in your hands, the statute does not leave you to negotiate on goodwill alone. It hands you a specific penalty: interest at 4% per month on the full withheld amount, compounding from the date the deposit was due, plus your reasonable attorney's fees and costs.
That penalty structure makes Michigan one of the more plaintiff-friendly states for deposit recovery. A $1,500 deposit held an extra three months accrues $180 in statutory interest before you even count filing fees or attorney's fees. A $3,000 deposit held six months past due is already $720 in penalties on top of the principal. The math works in your favor, and courts in Michigan apply it routinely.
Small claims court is the right venue for most of these disputes. Michigan District Court's small claims division handles claims up to $7,000, which covers a wide range of deposits plus accumulated penalties. The process is straightforward, hearings are typically set within 60 days of filing, and the rules are written so that a tenant without legal training can navigate them.
What Michigan's statutes actually require
Three sections of Michigan Compiled Laws govern security deposits. Together they form a tight framework that gives landlords clear obligations and tenants clear remedies when those obligations are ignored.
Mich. Comp. Laws § 554.602 sets the core rule: within 30 days after the tenant vacates the premises, the landlord must either return the full deposit or deliver an itemized written accounting of any deductions. The clock starts running when two things happen together: you vacate, and you provide your forwarding address in writing. If you handed keys back in person and left a written note with your new address, that is the start date. If you mailed keys and emailed your forwarding address, the later of those two events starts the clock.
Mich. Comp. Laws § 554.603 adds a separate obligation for long-term tenants. When a landlord holds a deposit for more than one year, interest begins accruing at 5% annually, or the rate paid by the landlord's bank, whichever is greater. This accrues on top of your principal and is owed to you at the end of the tenancy regardless of whether there are any deductions. Most tenants do not know to ask for it, and most landlords quietly pocket it.
Mich. Comp. Laws § 554.604 is the enforcement provision. It applies when the landlord ignores the 30-day rule and does not return the deposit or provide itemization. The penalty is 4% per month interest on the full withheld amount, from the date the deposit was due, plus reasonable attorney's fees and costs. The statute characterizes failure to comply as a violation of the tenant protection act, which matters if you want to add a broader consumer-protection claim.
There is no cap on the deposit amount in Michigan. A landlord can charge three months' rent or more if both parties agreed to it in writing. That means there is no ceiling on how much can be withheld improperly, and no ceiling on the penalty interest that accrues.
Your deadline to file
Michigan's statute of limitations for a security deposit claim runs six years under the general contract limitations period. That is substantially longer than most states. You are not in a rush in the sense of weeks, but you should file promptly for two practical reasons.
First, penalty interest at 4% per month means every month of delay is money the landlord owes you that you are not collecting. Waiting six months to file is leaving roughly 24% of the withheld amount on the table while you decide whether to act.
Second, evidence degrades. Move-out photos become harder to authenticate. Text threads get deleted. The landlord may claim they sent a statement you never received, and the longer you wait, the murkier the timeline becomes. File while the record is clear.
One thing that does have a firm deadline: your forwarding address. If you never provided it in writing, the 30-day clock has not started, and your landlord can argue they had no obligation to return anything. Put it in writing before you do anything else.
What to calculate before you file
Your claim in Michigan small claims has three components. Write down each before you calculate your filing fee or draft your complaint.
The principal is the portion of the deposit that was withheld without a lawful basis. Lawful deductions under Michigan law are limited to unpaid rent actually owed through the vacate date, damage to the unit beyond normal wear and tear, and other documented lease violations. Ordinary wear and tear is not deductible. A landlord who deducts for faded paint on a three-year tenancy, a worn carpet pad, or minor scuffs on walls is not on solid ground.
Penalty interest is calculated at 4% per month on the full withheld amount, beginning 30 days after you vacated and provided your forwarding address. Calculate from that date to your filing date. A $2,000 withheld deposit, four months past due, generates $320 in statutory interest. That number grows each month the landlord waits.
If your tenancy exceeded one year and the landlord never paid annual interest under § 554.603, add that to your claim as well. It is a separate obligation from the penalty interest and does not require you to prove bad faith. You only need to show that more than a year passed and no interest was paid.
Finally, add your filing fee and any documented service costs. Courts include these in judgments routinely. Keep every receipt.

How to file in Michigan District Court small claims
Michigan small claims operates within the District Court system, not a separate small claims court. You file at the District Court serving the county where the rental property is located. That is true even if you have since moved out of state.
The primary form is DC 84, the Small Claims Complaint. You fill in your name and address as plaintiff, the landlord's name and service address as defendant, a brief factual description of the claim, and the dollar amount you are seeking. Michigan courts require a specific dollar figure. You cannot file for "whatever the judge thinks is fair." Calculate your principal, penalty interest, and annual interest, add them together, and put that number on the form.
Filing fees scale with the amount claimed. Claims up to $600 carry a $30 fee. Claims between $600 and $1,750 cost $50. Claims above $1,750 up to the $7,000 cap are $100. These fees are added to your judgment when you win.
Once you file, the clerk sets a hearing date and issues a summons for your landlord. You are responsible for serving the summons. In Michigan small claims, service can be completed by a court officer, a county sheriff, or a registered process server. You cannot serve the papers yourself. Service must be completed at least five days before the hearing date.
What evidence wins this case
Michigan small claims hearings run short. Most judges allocate ten to twenty minutes per case. Your evidence has to tell the story quickly and without gaps. Organize it before you arrive.
Bring your lease in full, signed by both parties. This establishes the deposit amount, the tenancy terms, and any deduction provisions the landlord may try to invoke. If the lease authorizes specific deductions, you need it to counter those claims. If the lease is silent, so is the landlord's justification.
Bring proof that you paid the deposit: a bank statement showing the transfer, a cancelled check, a written receipt, or a combination. The landlord rarely disputes this, but you want it documented if they do.
Bring your forwarding address documentation. This is the piece most tenants forget. A text message, email, or signed note showing when and how you provided your new address establishes when the 30-day clock started. Without this, the landlord can argue the clock never began.
Bring move-out condition documentation. Photos with date stamps from your last day in the unit are the single most useful piece of evidence in a deduction dispute. If the landlord claims damage you did not cause, or charges for cleaning in a unit you left in good condition, photos from the final walkthrough answer both arguments. Video is even better.
Bring the demand letter you sent, along with USPS Certified Mail tracking showing delivery. Judges in Michigan small claims treat this as a signal that the tenant acted in good faith and gave the landlord a reasonable opportunity to resolve before filing. It also locks in the date from which you can argue the landlord received formal notice.
If the landlord sent an itemized deductions statement, bring that too. Highlight any deductions you are challenging and bring a written estimate or invoice showing the actual cost of repair at market rate.
If you have not sent a demand letter yet
Filing in small claims without sending a demand letter first is not prohibited in Michigan, but it costs you leverage. A well-drafted demand letter citing Mich. Comp. Laws § 554.604, naming the specific penalty interest rate, and setting a 14-day response deadline resolves about 85% of deposit disputes before the tenant ever sets foot in a courthouse.
If your landlord has not yet responded to written notice, send a Michigan demand letter for a withheld security deposit before filing. The letter itself is evidence at the hearing, it puts the landlord on formal notice of the statutory penalties, and in most cases it ends the dispute faster and cheaper than any court filing can.
If you already sent a demand letter and the deadline passed without payment, skip ahead. You have already done the right thing, and the letter becomes your first exhibit.
What to expect after the hearing
Michigan District Court judges either rule from the bench at the end of the hearing or take the matter under advisement and mail a written decision within a few weeks. Bench rulings are common in straightforward deposit cases where the facts are not in dispute and the primary question is the penalty calculation.
If you win, the court enters a money judgment against the landlord for the amount awarded plus your costs. The landlord has 21 days to appeal the judgment. Appeals go to the circuit court and require the landlord to post a bond. Most landlords in a deposit dispute do not appeal.
If the landlord does not pay voluntarily within 30 days of the judgment becoming final, Michigan gives you several collection tools. A writ of execution authorizes the court officer to seize the landlord's bank account funds or personal property up to the judgment amount. You can also record a certified copy of the judgment with the county register of deeds as a lien against any real property the landlord owns in that county. Michigan judgments accrue post-judgment interest at the statutory rate, so the cost of non-payment keeps growing.
Property management companies are common defendants in Michigan small claims. Serve them at their registered agent address, which you can look up through the Michigan Department of Licensing and Regulatory Affairs. The $7,000 small claims limit applies to your claim regardless of whether the defendant is an individual or a company.
