Prenuptial Agreement Cost in Michigan

Last updated 5 min read

A prenuptial agreement in Michigan typically costs $1,500 – $2,500 for a simple agreement and up to $4,500 – $8,000 for complex estates. Michigan prenup costs depend on attorney rates, how complex your finances are, and whether both spouses retain their own lawyer. This page isn't legal advice — it's a plain-English summary of how a prenup in Michigan works, what it costs, and what the state requires.

Cost breakdown

Complexity Typical cost Who this fits
Simple $1,500 – $2,500 W-2 income, no business, no kids from prior relationships
Moderate $2,500 – $4,500 Real estate, retirement accounts, modest separate property
Complex $4,500 – $8,000 Business interests, multi-state property, expected inheritance

Average attorney rate in Michigan: $200–$350/hr. Both spouses hiring separate attorneys typically adds 50–75% to the total bill.

What Michigan law requires

  • In writing: Yes — required.
  • Notarization: Not required, but recommended for evidentiary purposes.
  • Independent counsel: Strongly recommended (and often outcome-determinative if litigated).
  • Community property state: No — equitable distribution applies in the absence of an agreement.

The controlling statute is No unified statute; common law per Rinvelt v. Rinvelt — read the full text on the Michigan legislature site.

Michigan has no comprehensive premarital agreement statute. Enforceability is governed by case law — primarily Rinvelt v. Rinvelt — applying contract-law principles plus heightened fairness review: the agreement must be fair and reasonable, supported by full disclosure, and free of fraud, duress, or misrepresentation.

Does Michigan require a notary for a prenup?
No, Michigan does not require notarization by statute. A prenup must be in writing and signed by both parties; notarization is a best practice for evidentiary reasons but not a legal requirement.
Do both spouses need their own attorney in Michigan?

Joint representation — one attorney for both spouses — is among the most common grounds for a court to invalidate a prenup later. Even where it isn't strictly required, paying one lawyer to "save money" frequently costs the entire agreement.
