# Skill: Identify Issues in Counterparty Postnuptial Agreement

## 2. Failure modes the skill is correcting

- Treating the agreement like an ordinary commercial contract instead of a marital agreement subject to heightened scrutiny for voluntariness, disclosure, and fairness
- Missing disclosure gaps by reading the agreement in isolation rather than comparing it to supporting financial materials, correspondence, and schedules
- Failing to assess whether a self-reported valuation of a business, trust interest, or other complex asset is enough for meaningful informed consent
- Ignoring that one-sided allocation of income, appreciation, equity compensation, or support waivers may be legally vulnerable even if facially clear
- Overlooking child-related provisions, which often remain constrained by public policy regardless of contractual language
- Missing property-classification defects, especially where the agreement attempts to convert or isolate property in a way that may conflict with governing equitable-distribution or community-property rules
- Delivering a list of concerns without tying each one to the governing authority, the relevant document interaction, and the client-side consequence

## 3. Legal frameworks / domain conventions that apply

- Postnuptial enforceability generally turns on the governing jurisdiction’s rules for disclosure, voluntariness, independent advice, and substantive fairness; apply the controlling statute or leading case for the forum rather than generic contract principles alone
- Marital-agreement review should distinguish between premarital and postmarital contexts because courts often scrutinize postnuptial bargains more closely where the marital relationship may itself affect bargaining power
- Financial disclosure must be complete and intelligible enough for informed consent; omissions of material assets, liabilities, or contingent interests can support challenge to enforceability
- A disclosure supported only by unilateral self-valuation is weaker than one backed by statements, appraisals, account records, or other objective materials
- Property acquired during marriage may be marital, community, or otherwise divisible under the governing regime notwithstanding title labels; reclassification language must be checked against that regime
- Support waivers or termination provisions may be limited by statute, public policy, or court authority, especially as to child support and, in some jurisdictions, spousal support
- Equity compensation, deferred compensation, and appreciation rights may be treated differently from ordinary wages; analyze vesting, grant date, exercise date, and marital-period accrual under the applicable law
- Inheritance, gift, trust distributions, and similar separate-property concepts may be altered by commingling, transmutation, or tracing failures, so the agreement’s treatment must be tested against the factual record
- When the issue memo relies on a legal proposition, identify the controlling authority by name and section, or by leading case/rule if no statute controls

## 4. Analytical scaffolds

1. Read the agreement as a whole, then isolate each provision that affects property, support, disclosure, waiver, or enforcement mechanics
2. For each provision, identify the governing rule, the exact contractual treatment, and whether the treatment appears consistent with the forum’s marital-agreement law
3. Compare the disclosure package against the agreement and supporting documents to identify missing assets, missing liabilities, and missing contingent interests
4. For each asset class that is hard to value, test whether the disclosed methodology is objective enough to support informed waiver
5. For any one-sided allocation of income, appreciation, equity, or debt, assess the practical economic effect in the context of the total marital estate and the timing of accrual
6. For any support-related clause, determine whether it is mutual, unilateral, or limited by mandatory law or public policy
7. For any child-related term, separate what the parties can contract about from what remains subject to judicial control
8. For any provision that appears acceptable, identify it as a retention candidate so the client can preserve value while narrowing objections
9. When the record permits, tie each issue to a concrete scale from the documents — asset size, duration, category of property, or extent of the disclosure gap — and state how that scale changes the negotiation posture
10. When multiple parties, assets, periods, or provisions are implicated, evaluate each one separately rather than collapsing them into a single representative analysis

## 5. Vertical / structural / temporal relationships

- Use the negotiation timeline, email chain, or draft history to assess whether the client had a meaningful opportunity to review, seek independent advice, and absorb material changes before signature
- Use the financial summary or attached schedules as the baseline for completeness checks against the agreement’s recitals and disclosure exhibits
- Compare earlier and later drafts to identify newly inserted waivers, reallocations, or support changes that materially shift risk
- Consider whether the timing of an inheritance, bonus, vesting event, or liquidity event affects characterization at signing or at a future divorce-triggering event

## 6. Output structure conventions

- Prepare a single issue memorandum from the client’s perspective
- Use a short opening summary, then a prioritized issues section, then a short section identifying provisions that appear reasonable to retain, then a recommendation section
- Define an ordinal severity scale once near the top and apply it uniformly to each issue
- For each issue, include: severity, the controlling authority, the challenged provision or omission, why it matters, the document comparison or factual cross-check that exposes the problem, the practical client consequence, and the recommended counter-position
- Where the documents permit, include a concrete magnitude statement tied to the source materials without inventing numbers or performing unsupported reconciliation arithmetic
- Treat authority citations as mandatory for each legal proposition; do not state a conclusion without naming the rule, statute, regulation, or leading case that supports it
- End with an explicit Recommended Actions block that assigns the next step to counsel or another responsible person and ties it to the document review or signing timeline
