State-specific manual editorial

Washington's source-catalogued package points to the Matson framework, which separates substantive fairness from procedural safeguards involving disclosure, knowledge, voluntary execution, and independent advice.

Because this package is built from leading appellate authority rather than a comprehensive premarital-agreement act, later cases and Title 26 must be checked by Washington counsel.

Questions people actually ask

Washington review, without pretending the facts are settled.

Each answer is tied to source IDs in the current state package. Open the citations and check for later authority before relying on a proposition.

Why does the guide distinguish substantive and procedural review?

The cited Washington opinion applies a framework that first examines substantive fairness and, when necessary, disclosure and voluntary execution with independent advice.

What property information matters?

The procedural inquiry described in the cited authority considers knowledge of the amount, character, and value of property.

Is this a complete Washington-law test?

No. The package expressly requires review of later appellate decisions and mandatory Title 26 rules.

Worked issue-spotting examples

How document facts become research questions.

These examples do not predict an outcome. They show the boundary between a fact pattern, a source-backed issue, and the legal judgment still required.

The one-sided allocation

A draft allocates most appreciation to one party. Washington's cited framework directs counsel to examine substantive fairness before relying on procedural evidence.

Question to carry forward: How does current Washington authority assess substantive fairness for these terms?

The valuation gap

Assets are listed by name without approximate values. The cited procedural framework makes knowledge of amount, character, and value a concrete evidence question.

Question to carry forward: What valuation disclosure or independent knowledge can be proved?

01

Signing formalities

Confirm the complete agreement and every incorporated schedule use the required form and signatures.

  • RCW 26.16.120 · A community-property agreement effective at death must be written, signed and sealed, witnessed, acknowledged, and certified like a real-estate deed.
02

Acknowledgment

Check whether the agreement or a related instrument uses an acknowledgment, notarization, witness, or recording formality.

No separate source record is catalogued for this topic. That is a research-coverage statement, not a claim that no applicable law exists.

03

Effective date

Identify the event and date on which the agreement says it becomes effective.

04

Permitted subjects

Map each material clause to a subject the cited authorities address and flag terms requiring separate authority.

05

Property

Reconcile property labels with title, income, appreciation, debt, and disposition terms.

  • RCW 26.09.080 · Absent an enforceable agreement, the court makes a just and equitable disposition of community and separate property after statutory factors.
  • RCW 26.16.010–.030 · Title 26.16 defines separate and community property and management rights against which contract terms operate.
06

Spousal support

Identify every support waiver, cap, formula, review event, and enforcement-time safeguard.

  • RCW 26.09.090 · Section .090 supplies current maintenance factors relevant to the effect and substantive fairness of a waiver.
07

Children and support

Flag any term that attempts to predetermine child support, custody, or another child-related decision.

08

Amendment and revocation

Confirm every claimed amendment or revocation is complete and follows the applicable form.

  • RCW 26.16.120 · A section .120 death agreement may be altered in the same manner and remains subject to creditor rights, fraud, and equitable cancellation.
09

Voluntariness

Build a factual timeline of drafts, negotiations, pressure, capacity, language access, and signing.

10

Financial disclosure

Compare the agreement and schedules against assets, debts, income, business interests, trusts, and any waiver.

11

Independent counsel

Record who advised each party, when advice occurred, and which draft was reviewed.

12

Timing

Measure the time between first draft, material revisions, legal review, wedding, and signing.

13

Public assistance

Identify support terms that could interact with public-benefit eligibility at enforcement.

No separate source record is catalogued for this topic. That is a research-coverage statement, not a claim that no applicable law exists.

14

Void marriage

Identify whether the agreement addresses a marriage later determined to be void.

No separate source record is catalogued for this topic. That is a research-coverage statement, not a claim that no applicable law exists.

15

Other limitations

Identify severability, limitations, public-policy, choice-of-law, and other enforcement boundaries.

Matrix and list placement describes the records in PrenupsAI's current evidence packages. It does not rank legal strictness, predict enforceability, or mean that an unlisted state has no applicable rule. Open the cited sources to inspect the underlying authority.

Method, not a verdict

How to turn fifteen prompts into a defensible review file.

331 words of shared evidence methodology accompany the state-specific editorial and authority records above.

Use the checklist as an evidence map

Work from the complete agreement outward. Preserve the best available signed copy, every incorporated schedule, and any amendment or revocation before answering individual questions. For each checklist row, distinguish three things: what the document says, what an outside record can prove, and what the cited authority addresses. Those categories overlap, but they are not interchangeable. A recital may identify the parties’ stated understanding without proving delivery; a bank statement may prove an account existed without deciding its legal classification; a statute may identify a standard without resolving disputed facts.

Mark an item complete only when the underlying record is identified, not merely because the agreement contains reassuring language. If a source is absent, record the gap and route it for research. Do not convert ‘not separately catalogued’ into ‘no law exists.’ That discipline is what makes the checklist useful across both dense statutory packages and states whose rules depend more heavily on cases or adjacent bodies of law.

Keep a source-and-version trail

Record the package version and effective-through date shown above, the date each authority was opened, and whether a later-authority search was performed. Save exact clause quotes with page or section references. When facts change—through relocation, marriage, amendment, property transfer, separation, death, or litigation—create a new review snapshot rather than overwriting the old one. The resulting trail lets another reviewer understand which document, facts, and legal source set supported each observation.

A checklist can identify missing evidence and research questions; it cannot certify validity, predict enforcement, select governing law, or replace a time-sensitive professional judgment. Use narrow language such as ‘the reviewed file does not contain the referenced schedule’ instead of ‘no disclosure occurred.’ That difference is not defensive filler. It is the basic quality control that keeps evidence reporting accurate.

End each review with a dated list of unresolved facts, assigned follow-up work, and the authority that made each question material. A visible open item is safer than an unsupported green check.
