Filing an Affidavit of Heirship in Michigan Probate Court

When a family member dies without a will in Michigan, transferring their property to the rightful heirs can feel overwhelming. You may not want to go through full probate, especially if the estate is small or consists mainly of real estate. That's where filing an affidavit of heirship comes in. It's a legal document that identifies the deceased person's heirs and can help transfer property rights without a lengthy court process. Knowing how to file an affidavit of heirship in Michigan probate court the right way can save your family time, money, and frustration during an already difficult time.

What Is an Affidavit of Heirship in Michigan?

An affidavit of heirship is a sworn legal statement that identifies the surviving heirs of a person who died (the "decedent"). It lists the decedent's family members, their relationship to the decedent, and explains who is entitled to inherit the property. In Michigan, this document is most commonly used when someone dies without a will (intestate) and the family wants to transfer ownership of real estate or other assets without opening a formal probate case.

The affidavit is typically signed by someone who personally knew the decedent and their family history often a close friend, relative, or neighbor and it must be notarized. Once filed or recorded, it serves as a public record that establishes the chain of title to the property.

When Does Filing an Affidavit of Heirship Make Sense?

Not every situation calls for this document. An affidavit of heirship in Michigan is most useful when:

The decedent owned real estate (such as a home or land) and died without a will.
The estate is straightforward, with no disputes among the heirs.
You want to avoid the time and cost of formal probate proceedings.
There are no significant debts or creditor claims against the estate.
Title companies or buyers need proof of ownership to complete a real estate sale.

For example, imagine your mother passed away owning her home in Michigan. She had no will, and you and your sibling are her only children. No one is contesting who should inherit. Rather than opening a full probate case, you could file an affidavit of heirship to establish your ownership rights and eventually sell or refinance the property.

What Are the Requirements to File an Affidavit of Heirship in Michigan?

Michigan law allows affidavits related to title of land under MCL 565.451. To file a valid affidavit of heirship, you generally need to meet these conditions:

Sworn statement: The affidavit must be signed under oath and notarized.
Disinterested witness: At least one person who is not an heir must swear to the decedent's family history, marital status, and surviving heirs. This person should have personally known the decedent. You can learn more about who can sign as a witness on a Michigan affidavit of heirship.
Property description: The affidavit should include a legal description of the real property involved.
Decedent information: Full legal name, date of death, and county of residence of the deceased person.
Heir identification: Names, addresses, and relationships of all heirs.

Some Michigan counties have their own specific formatting preferences, so it's worth checking with your local probate court or register of deeds before submitting.

How Do You File an Affidavit of Heirship Step by Step?

The filing process involves several steps. Here's a breakdown of what to expect:

Gather information. Collect the decedent's death certificate, property records (including the legal description of any real estate), and details about the family tree.
Identify a qualified witness. Find someone who knew the decedent well and can verify the family relationships. This person cannot be an heir.
Draft the affidavit. Write the affidavit using the required format. Include all the information listed above. Some counties provide forms, but there is no single statewide template.
Have the affidavit notarized. Both the person signing the affidavit (the affiant) and the witness must sign in front of a notary public.
File or record the affidavit. File the original notarized affidavit with the Register of Deeds in the county where the property is located. This makes it part of the public land records.
Notify relevant parties. If you need to transfer title, contact the title company, lender, or any other party that requires proof of heirship.

Where Do You File the Affidavit Probate Court or Register of Deeds?

This is a point that confuses many families. In Michigan, an affidavit of heirship is typically filed with the county Register of Deeds, not the probate court. Its primary purpose is to establish a chain of title in the public land records so that the heirs can sell, transfer, or refinance the property.

However, the affidavit may be used in probate proceedings as supporting evidence. If you do open a probate case, the court may accept the affidavit as proof of who the heirs are, but the affidavit itself is not a probate court order. If the estate has complex issues such as disputes among heirs, significant debts, or unclear family relationships you may need to go through probate court instead. Michigan's probate courts handle estates under the Estates and Protected Individuals Code (EPIC).

Who Can Sign as a Witness on the Affidavit?

The witness is one of the most important parts of the process. Michigan requires that the witness be a disinterested party meaning someone who does not stand to inherit anything from the estate. The witness should have personal knowledge of the decedent's family and marital history. Good choices include a long-time friend, neighbor, coworker, or someone from the decedent's community who knew the family over many years.

Using a witness who is also an heir, or who only knows partial information about the family, can cause the affidavit to be rejected by a title company or challenged later. For more detail on witness qualifications, review our guide on who can sign as a witness.

What Common Mistakes Should You Avoid?

Filing an affidavit of heirship may seem straightforward, but small errors can cause big problems down the road. Watch out for these common mistakes:

Using an heir as the witness. This is the most frequent error. The witness must have no financial interest in the estate.
Incomplete property description. A vague or missing legal description can make the affidavit useless for title purposes. Always use the exact legal description from the deed.
Missing notarization. An unnotarized affidavit has no legal weight in Michigan. Make sure all signatures are completed in front of a notary.
Failing to list all heirs. If you leave out an heir even one you're not close with the affidavit could be challenged or voided.
Confusing the affidavit with a court order. An affidavit of heirship does not grant legal authority the way a probate court order does. It simply records the facts about the decedent's heirs.
Filing in the wrong county. The affidavit must be recorded in the county where the real property is located, which may differ from where the decedent lived.

Do You Need a Lawyer to File an Affidavit of Heirship?

Michigan does not require you to hire an attorney to file an affidavit of heirship. Many families handle this on their own, especially for simple estates. However, there are situations where legal help is worth considering:

The estate involves multiple properties in different counties.
There are half-siblings, stepchildren, or other complicated family relationships.
A title company has rejected a previous version of the affidavit.
Creditors are making claims against the estate.

How Is an Affidavit of Heirship Different from a Small Estate Affidavit?

Michigan offers another option for settling small estates: the small estate affidavit (sometimes called a "petition and order for assignment" under EPIC). While both tools help avoid full probate, they work differently:

An affidavit of heirship primarily deals with establishing title to real property and is filed with the Register of Deeds.
A small estate affidavit is filed through the probate court and is used to transfer personal property (bank accounts, vehicles, etc.) when the estate's value falls below a certain threshold.

Understanding which one applies to your situation matters. A family might need one or both depending on the types of assets involved. For a side-by-side comparison, see affidavit of heirship vs. small estate affidavit in Michigan.

What Happens After the Affidavit Is Recorded?

Once the affidavit of heirship is recorded with the Register of Deeds, it becomes part of the public property records. From there:

Title companies can use it to confirm ownership when the heirs sell the property.
Heirs can work with the county assessor to update property tax records.
Lenders may accept it as part of a refinancing application.

Keep in mind that some title companies in Michigan may still require additional documentation or a quiet title action before they will issue title insurance. It's a good idea to contact the title company early in the process to find out exactly what they need.
