How to Write and Notarize an Affidavit in Michigan
An affidavit is just facts, in order, sworn to be true. Most rejected affidavits fail on structure, not honesty.
Quick Answer
What makes an affidavit valid in Michigan?
A Michigan affidavit is a written statement of facts sworn or affirmed before a notary public. To hold up, it should identify the person making it, state how that person knows the facts, set the facts out in numbered paragraphs with dates and specifics, avoid opinions and arguments, and be signed in the notary's presence by a signer who presents valid, unexpired government photo identification. The notary administers the oath and verifies identity — the notary does not verify that the contents are true. That responsibility belongs to the signer, and knowingly swearing to false statements carries criminal exposure. Some Michigan courts and agencies require a specific numbered form rather than a free-form affidavit, so always check the requirement before drafting.

How to do it properly
Ask the requesting party exactly what they need
Schools, banks, title companies, courts, and consulates all have different expectations, and some have their own mandatory form. Get the requirement in writing before you draft anything. This one step prevents most rejections.
Check whether a court form is required instead
Michigan courts frequently require a specific SCAO form. If the affidavit is going into a court file, confirm the form number first — a free-form statement can be refused at the counter.
Identify yourself at the top
Full legal name, address, and your relationship to the matter. The reader needs to know who is speaking before they read a word of the facts.
State how you know the facts
Personal observation, your own records, a role you held, years of knowing the family. Without this, the reader has no reason to credit anything that follows.
Write the facts in numbered paragraphs
One fact per paragraph, in chronological order, with dates, names, addresses, and amounts. Use 'on or about' when you are not certain of an exact date instead of guessing.
Cut the opinions
Strike anything that is an argument, a characterization, or a conclusion. 'He was reckless' is opinion. 'He drove through the stop sign without slowing' is a fact you witnessed.
Label what you did not witness yourself
If you were told something rather than seeing it, say so plainly. Reviewers weigh firsthand and secondhand information very differently, and hiding the difference damages the whole statement.
Attach and label exhibits
Reference supporting documents in the text as Exhibit A, Exhibit B, and attach them behind the affidavit so nothing gets separated.
Do not sign it yet
The signature belongs in front of the notary. A pre-signed affidavit generally has to be redone.
Appear before the notary with valid photo ID
Bring unexpired government identification. The notary will identify you, administer the oath or affirmation, watch you sign, and complete the jurat.
Keep signed originals
Get more originals than you think you need — receiving parties often keep theirs. If the document is going to another country, ask about an apostille from the Michigan Secretary of State.
What belongs in a Michigan affidavit
| Element | Why it matters |
|---|---|
| Affiant identification | Tells the reader who is swearing and their connection to the matter |
| Basis of knowledge | Explains why this person would know these facts |
| Numbered factual paragraphs | Makes the statement readable and easy to reference |
| Dates, names, addresses, amounts | Turns a story into something verifiable |
| Exhibits | Backs up the facts with documents |
| Oath or affirmation language | Makes it a sworn statement rather than a letter |
| Signature in the notary's presence | Required — pre-signing generally invalidates the notarization |
| Jurat and notary seal | The notary's certificate that you appeared, were identified, and swore to it |
