Steps to File for Letters Testamentary in Michigan

When someone passes away in Michigan and leaves behind a will, the person named as executor can't just start managing the estate right away. They need legal authority from the probate court first. That authority comes in the form of letters testamentary. Without them, banks won't release accounts, title companies won't transfer property, and creditors have no one to deal with. If you've been named executor and you're trying to figure out how to file for letters testamentary in Michigan step by step, this article walks you through the actual process what to prepare, where to go, what to expect, and how to avoid setbacks.

What Are Letters Testamentary and Why Do You Need Them?

Letters testamentary is a court-issued document that officially authorizes the executor named in a will to act on behalf of a deceased person's estate. Think of it as your legal badge. Without it, third parties banks, financial institutions, government agencies, and others won't let you access, manage, or distribute the decedent's assets.

In Michigan, this document is issued by the probate court in the county where the deceased person lived at the time of their death. Once granted, the letters testamentary give you the power to pay debts, file taxes, transfer property, and distribute assets according to the will.

You can learn more about what documents are needed to obtain letters testamentary in Michigan before you start the process, which can save you multiple trips to the courthouse.

Who Is Eligible to File?

Only the person named as the executor (also called a "personal representative") in the decedent's will can petition for letters testamentary. If that person is unable or unwilling to serve, a successor named in the will may step in. If no successor is named or available, interested parties can petition the court to appoint an administrator instead but that's a different process.

You must also be at least 18 years old and of sound mind. Michigan law also disqualifies individuals who have been convicted of a felony or who are otherwise found unsuitable by the court.

What Should You Do Before Going to Court?

Before you file anything with the probate court, take these preparatory steps:

Locate the original will. The court requires the original, not a photocopy. Search the decedent's home, safe deposit box, or contact their attorney.
Get certified copies of the death certificate. You'll need several. Most institutions require certified copies, not just photocopies. Order at least 10 to 15 from the county clerk or the Michigan Department of Health and Human Services.
Identify the county of residence. Filing happens in the probate court for the county where the decedent lived not where they died, if those are different.
Gather estate information. Make a preliminary list of assets, debts, and beneficiaries. This isn't required at filing but will help you complete the forms accurately.

Step-by-Step: How to File for Letters Testamentary in Michigan

Step 1: Obtain the Correct Probate Court Forms

Michigan uses standardized probate court forms. The main form you'll need is PC 571 (Application for Probate and/or Appointment of Personal Representative). You may also need:

PC 572 Acceptance of Appointment
PC 573 Letters Testamentary (to be issued by the court)
PC 574 Notice of Appointment and Duties of Personal Representative
MC 97 Protected Personal Identifying Information form

You can download these forms from the Michigan Courts website or pick them up at your local probate court. For a detailed checklist, see our page on Michigan probate court letters testamentary application requirements.

Step 2: Complete the Application (PC 571)

Fill out the application carefully. You'll need to provide:

The decedent's full legal name, date of death, and county of residence
Your name and relationship to the decedent
The names and addresses of the decedent's heirs and beneficiaries
A statement that the will is being offered for probate
Whether the decedent owned real estate
Whether you're requesting supervised or unsupervised administration

Errors on this form are one of the most common reasons for delays. Double-check names, dates, and addresses before submitting.

Step 3: File the Application With the Probate Court

Bring the completed application, the original will, a certified death certificate, and any other required forms to the probate court in the decedent's county of residence. You'll also need to pay a filing fee, which in Michigan is typically around $175, though it can vary slightly by county.

Step 4: Attend the Probate Court Hearing (If Required)

Michigan probate courts may or may not require a hearing, depending on the county and the circumstances. In many straightforward cases with an uncontested will, the court may issue letters testamentary without a hearing. However, if anyone objects to the will or to your appointment, a hearing will be scheduled.

You'll receive notice of any hearing date. If a hearing is held, be prepared to answer questions about the will, your qualifications, and your plan for administering the estate.

Step 5: Accept Your Appointment and Receive Letters Testamentary

Once the court approves the application, you'll sign the Acceptance of Appointment (PC 572), which confirms you understand your legal duties as personal representative. After that, the court issues the Letters Testamentary (PC 573). You'll receive certified copies request multiple copies since banks and other institutions typically require them.

Step 6: Notify Interested Parties

Michigan law requires you to send a Notice of Appointment (PC 574) to all interested parties, including heirs named in the will, beneficiaries, and known creditors. This notice must be sent within 14 days of your appointment. You should also publish a notice to creditors in a local newspaper, giving unknown creditors a chance to file claims.

How Long Does It Take to Get Letters Testamentary in Michigan?

The timeline depends on the court's caseload and whether there are any complications. In a straightforward, uncontested case, you might receive letters testamentary within two to four weeks of filing. If there are objections, missing documents, or errors in your paperwork, it can take several months.

Counties like Wayne and Oakland tend to have higher caseloads, which can add processing time. Filing early and submitting complete paperwork is the best way to avoid delays.

What Are Common Mistakes That Delay the Process?

Filing in the wrong county. You must file in the county where the decedent lived, not where they died or where the property is located.
Submitting a copy of the will instead of the original. Michigan courts require the original document. If the original is truly lost, you'll need to go through additional legal steps to prove its contents.
Incomplete or incorrect forms. Missing signatures, wrong dates, or incorrect names will send you back to square one.
Not ordering enough death certificates. You'll need certified copies for banks, insurance companies, government agencies, and more. Running out mid-process causes real delays.
Forgetting the MC 97 form. This form protects sensitive personal information. Omitting it can cause your filing to be rejected.

How Much Does the Whole Process Cost?

The primary cost is the court filing fee, which is approximately $175. Beyond that, you may have costs for:

Certified death certificates (typically $15 to $25 each depending on the county)
Publication of the notice to creditors in a newspaper
Legal fees if you hire a probate attorney (not required, but often recommended for complex estates)

The estate itself typically reimburses these expenses, not the executor personally.

Do You Need a Lawyer to File for Letters Testamentary?

Michigan does not require you to hire an attorney to file for letters testamentary. Many executors handle simple estates on their own. However, if the estate involves significant assets, real property in multiple states, business interests, tax complications, or disputes among beneficiaries, working with a probate attorney can save you time and protect you from personal liability.

As an executor, you're legally responsible for managing the estate properly. Mistakes even honest ones can expose you to personal financial risk. The Michigan State Bar's lawyer referral service can help you find a probate attorney if you need one.

What Happens After You Get Letters Testamentary?

Once letters testamentary are issued, your work as executor begins in earnest. Here's what typically comes next:

Open an estate bank account. Use the letters testamentary to establish a separate account for the estate.
Inventory the estate assets. Michigan requires you to file an inventory with the court within 91 days of appointment.
Pay valid debts and taxes. Creditors must be paid from estate assets before any distribution to beneficiaries.
File required tax returns. This includes the decedent's final income tax return and possibly estate tax returns.
Distribute remaining assets. After debts and taxes are paid, distribute what's left according to the will.
Close the estate. File a final accounting with the court and petition for discharge.
