Formation and lifecycle
Execution requirements to investigate
Minnesota witness and acknowledgment proof
Duly acknowledged and attested agreements provide prima facie proof of acknowledged matters, while current execution independently requires two witnesses and acknowledgment.
Minn. Stat. § 519.11, subds. 1(d), 1b(b)(3)Minnesota personal-execution boundary
A power of attorney does not satisfy the current writing, witness, and acknowledgment execution requirement.
Minn. Stat. § 519.11, subd. 1b(d)Minnesota marriage consideration and operative boundary
The agreement is made before solemnization, and marriage itself supplies adequate consideration for a conforming agreement.
Minn. Stat. § 519.11, subd. 1(a), (c)Minnesota amendment and revocation route
After marriage, an antenuptial agreement may be amended or revoked only by a valid postnuptial agreement complying with section 519.11 and other Minnesota law.
Minn. Stat. § 519.11, subd. 2aMinnesota 2024 applicability line
The rewritten section applies to antenuptial and postnuptial agreements executed on or after August 1, 2024; earlier instruments require the prior statute and common law.
Minn. Stat. § 519.11, subd. 6; 2024 Minn. Laws ch. 101, art. 3, § 1Minnesota pre-2024 marital-property framework
Under former section 519.11, statutory safe-harbor treatment was limited and common-law Kinney factors governed marital-property provisions; Kremer found inadequate consideration and duress on its record.
Kremer v. Kremer, 912 N.W.2d 617 (Minn. 2018)Minnesota older common-law fairness factors
Kinney applied common-law equitable-and-fair execution factors to a 1969 agreement, including fraud, undue influence, duress, consideration, knowledge, rights, and counsel opportunity.
In re Estate of Kinney, 733 N.W.2d 118 (Minn. 2007)What the agreement addresses
Permitted subjects and legal limits
Minnesota permitted subjects
A conforming agreement may address marital and nonmarital property at dissolution or separation, spousal maintenance, and specified estate rights.
Minn. Stat. § 519.11, subd. 1(b)Minnesota seven-day burden allocation
Execution at least seven days before marriage creates a presumption of enforceability and puts the burden on the challenger; a shorter interval removes the presumption and puts the burden on the proponent.
Minn. Stat. § 519.11, subd. 1b(c)Minnesota substantive-unconscionability test
Courts consider whether all or part is so substantively unfair as to be unconscionable by its terms or because of qualifying changed circumstances.
Minn. Stat. § 519.11, subd. 1c(a)Minnesota unforeseen-change safeguard
Drastically changed circumstances not originally foreseen may make enforcement inconsistent with the parties' reasonable expectations at execution.
Minn. Stat. § 519.11, subd. 1c(a)Minnesota default-award deviation boundary
An agreement need not approximate statutory property division or maintenance, and deviation from default standards alone does not establish unconscionability.
Minn. Stat. § 519.11, subd. 1c(b)Minnesota express-severability rule
If the agreement unambiguously permits severability, a court may sever an unenforceable provision and enforce the remainder.
Minn. Stat. § 519.11, subd. 1(e)Minnesota two-year postnuptial presumption
A postnuptial agreement is presumed unenforceable if either spouse begins separation or dissolution within two years, unless the proponent proves it fair and equitable.
Minn. Stat. § 519.11, subd. 1d(d)Minnesota child best-interest boundary
Custody and parenting time require current best-interest findings on all relevant statutory factors.
Minn. Stat. § 518.17, subd. 1Minnesota child-support guideline boundary
The child-support guideline is a rebuttable presumption in proceedings establishing or modifying support, subject to approved agreements and lawful deviation rules.
Minn. Stat. § 518A.35Minnesota premarital probate-waiver cross-reference
A premarital waiver of survivor election and related probate rights must comply with section 519.11; postmarital waivers have the separate writing, signature, and fair-disclosure rule in section 524.2-213.
Minn. Stat. § 524.2-213Process evidence
Financial disclosure, voluntariness, counsel, and timing
Minnesota current procedural-fairness test

Minn. Stat. § 519.11, subd. 1bMinnesota nonwaivable full disclosure
Each party must provide reasonably accurate material income facts, good-faith property-value estimates, and the basis for those disclosures; this requirement cannot be waived.
Minn. Stat. § 519.11, subd. 1b(a)–(b)(1)Minnesota meaningful independent-counsel opportunity
Each party must have a meaningful opportunity to consult independent counsel of that party's choosing.
Minn. Stat. § 519.11, subd. 1b(b)(2)Minnesota seven-day execution rule

Minn. Stat. § 519.11, subd. 1b(b)(4)Minnesota mandatory separate counsel for postnuptial agreements

Practical examples
These examples show how document facts can intersect with the cited sources. They do not predict a court result.
The wedding-day signature
The parties sign on the day of the ceremony. Minnesota's current statute identifies execution before the day of marriage as a specific formality.Minn. Stat. § 519.11, subd. 1b(b)(3)
Ask local counsel
Does the signing date satisfy the current Minnesota statute, and which version applies?
The missing second witness
The agreement has both party signatures and a notary certificate but only one witness. Minnesota's enumerated formalities make the witness record a threshold issue.Minn. Stat. § 519.11, subd. 1b(b)(3)
Ask local counsel
Was the agreement witnessed and acknowledged in the manner section 519.11 requires?
