Two of the most under-serviced niches in modern wealth management — the post-decree divorcing client whose financial life has just been bisected by a QDRO and whose IPS hasn't been rewritten in seven years, and the special-needs household whose parents are aging into the question of "what happens to our adult child after we're gone" — share the same operational pattern: legally dense, emotionally loaded, factually intricate, and dramatically compressed by AI extraction and AI drafting against named planning artifacts. This lesson installs the workflow for both: the divorce-and-asset-division AI pass with QDRO mechanics and Social Security ex-spouse benefit analysis, and the special-needs trust and ABLE coordination pass with Medicaid/SSI means-test preservation and the letter-of-intent draft that survives the parents.

The Divorce Intake and the Asset-Division Tax-Cost Pass

The divorcing client arrives, typically, with a partially-executed marital settlement agreement (MSA), a draft QDRO if a retirement account is in play, and a sense that "we agreed to split it 50/50." That framing — equal-dollar split — is almost always the wrong frame, because two assets with identical pre-tax dollar values can carry materially different tax burdens depending on basis, account type, and the recipient's tax bracket. The AI workflow's first job is to convert the asset list into an after-tax-equivalence table.

Inputs: the asset schedule from the MSA (taxable accounts, retirement accounts, primary residence, vacation property, life insurance cash value, business interests, deferred comp, ISO/RSU/ESPP grants, restricted stock, vested options), the cost basis on each (extracted via Holistiplan from the prior-year 1099-Bs and Schedule D; for residences, the original purchase HUD-1 plus capital improvements; for retirement accounts, the contribution history from Form 5498 and the after-tax-basis tracking on Form 8606), the marginal tax bracket projected for each spouse post-divorce, the state of residence post-decree (which often changes), and the holding-period status (long-term vs. short-term capital gain treatment).

The output is the after-tax-equivalence table: for each asset, the pre-tax value, the embedded tax cost if liquidated, the after-tax value, and the equivalence ratio. A $400,000 taxable account with $100,000 basis carries $300,000 of unrealized LTCG ($71,400 tax at 23.8% federal NIIT-inclusive in a top bracket) and is worth roughly $328,600 after-tax. A $400,000 traditional IRA carries $400,000 of fully-deferred ordinary income ($148,000 tax at 37%) and is worth roughly $252,000 after-tax. A $400,000 Roth IRA is worth $400,000 after-tax. A $400,000 primary-residence equity tranche (with §121 $250K-single / $500K-MFJ exclusion preserved for the recipient) is worth $400,000 after-tax for the first $250K of single-filer gain. The AI surfaces the disparity. The MSA negotiation that proceeded on pre-tax dollar equivalence routinely produces a 20-35% after-tax inequity that one spouse's attorney didn't catch.

QDRO Mechanics, IRC §414(p), and the §408(d)(6) Transfer Rule

The Qualified Domestic Relations Order under IRC §414(p) is the mechanism that splits an ERISA-governed retirement plan (401(k), 403(b), defined benefit, cash balance, pension) between the participant-spouse and the alternate-payee-spouse. The plan administrator pre-approves the QDRO, the order is entered by the court, and the plan splits the account according to the QDRO terms — typically as a separate account (the "separate interest" approach) or a shared payment stream (the "shared payment" approach). The split itself is tax-free; subsequent distributions are taxed under normal retirement-plan rules.

The §72(t) 10% early-distribution penalty exception under §72(t)(2)(C) applies specifically to QDRO distributions from a qualified plan — meaning the alternate payee can take a cash distribution from the participant's 401(k) directly under the QDRO without the 10% penalty, even if the alternate payee is under age 59½. This is a one-time-only window; once the funds roll to an IRA, the §72(t) exception evaporates and any subsequent withdrawal before 59½ is back under the standard 10%-penalty regime (subject to other exceptions). The AI's job is to surface this election to the alternate payee whose immediate cash needs (lawyer fees, housing, transition cost) may make the direct QDRO distribution far superior to rolling-and-then-withdrawing.

For IRA splits (which are not ERISA-governed and do not use QDROs), IRC §408(d)(6) provides the tax-free transfer mechanism. The IRA transfer must be made pursuant to a divorce or separation instrument and is treated as a transfer of the entire interest (or partial interest) from the participant to the spouse, with the spouse becoming the IRA owner from that point. This is the correct citation for divorce IRA transfers — distinct from IRC §408(d)(2) and §72(e)(8), which together govern the backdoor-Roth pro-rata rule and were misciteed to §408(d)(6) in pre-2026 guidance.

Social Security Ex-Spouse Benefit and the 10-Year Marriage Rule

A divorced spouse is eligible for a Social Security benefit on the ex-spouse's earning record if the marriage lasted at least 10 years, the claiming spouse is at least 62, the claiming spouse is unmarried at the time of claiming (subsequent remarriage after 60 is treated differently), and the ex-spouse's record produces a higher benefit than the claiming spouse's own. The ex-spouse benefit is up to 50% of the ex-spouse's Primary Insurance Amount (PIA) at the claimer's Full Retirement Age (FRA), reduced for early claiming. The claim is independent of the ex-spouse's claiming status — the claiming spouse does not need to wait for the ex to file — provided the divorce has been final for at least two years.

For the 64-year-old claiming spouse whose own PIA is $1,400 and whose 17-year-marriage ex's PIA is $3,200, the ex-spouse benefit calculation at FRA produces $1,600/month vs. her own $1,400 — meaning the ex-spouse claim adds $200/month or $2,400/year for life. Delayed claiming to age 70 doesn't increase the ex-spouse benefit (delayed retirement credits don't apply to spousal/ex-spouse benefits), so the optimal claim timing differs from a single-life PIA optimization. The AI's job is to project both records side by side, run the breakeven, surface the survivor-benefit implications (the ex-spouse death triggers a survivor benefit equal to 100% of the deceased ex's benefit, subject to the survivor's age and FRA reductions), and produce the integrated claiming memo. Cross-referenced to L3 Ch4 L1 (Social Security claiming and coordination memo).

The Post-Divorce IPS Rewrite

The IPS that supported a two-income household with shared retirement goals is dead the moment the decree is signed. The AI runs the IPS through L2 Ch5 L2 (Update an IPS After a Life Event) with the new facts: new income, new asset base, new dependents, new state of residence, new beneficiary intent, new risk tolerance (single-income households tolerate volatility differently than two-income households), new liquidity profile, and any new estate-planning instructions. The redline output is the AI-drafted IPS with every section flagged for advisor review and client signoff. The Reg BI file documents the rewrite as a recommendation under the Care Obligation.

SNT Funding, ABLE Coordination, and the Medicaid/SSI Means-Test Preservation

The special-needs household pivots on one operational reality: any asset titled in the disabled beneficiary's name in excess of the SSI/Medicaid asset limit (typically $2,000 for SSI, varying for state Medicaid waivers) disqualifies the beneficiary from means-tested benefits. The Special Needs Trust (SNT) is the legal vehicle that holds assets for the disabled beneficiary's benefit without being treated as the beneficiary's own asset for means-test purposes. There are two structures: the first-party SNT under 42 USC §1396p(d)(4)(A) (funded with the beneficiary's own assets, typically from a personal-injury settlement or an inheritance, requires a Medicaid-payback provision at death) and the third-party SNT (funded with parents' or others' assets, no payback required).

The ABLE account under IRC §529A is the complementary vehicle: the beneficiary herself owns the ABLE account, contributes up to the annual gift-tax-exclusion limit ($19,000 for 2026, plus an additional amount equal to the beneficiary's earned income up to the federal poverty level for the ABLE-To-Work expansion), and the account assets up to $100,000 are excluded from the SSI asset test (Medicaid-asset-test exclusion typically goes higher under state programs). The ABLE account funds the beneficiary's daily Qualified Disability Expenses (housing, transportation, health, education, employment training, assistive technology) directly without triggering benefit cuts. The 2026 maximum ABLE contribution is $19,000 plus the ABLE-To-Work supplement (up to ~$15,000 depending on poverty-level numbers).

The AI's job is to model the coordinated funding: the parents fund a third-party SNT (no Medicaid payback, more flexibility), they contribute to the beneficiary's ABLE account up to the annual limit (the day-to-day expense bucket), and the SNT can also fund the ABLE (intra-vehicle transfer, no gift-tax issue when SNT-to-ABLE for the same beneficiary). The SNT's investment policy (drafted by an SNT-experienced attorney; AI helps with the model) targets growth for long-horizon disabled beneficiaries with modest current-spending needs; the ABLE's investment options are state-program-specific (most use Vanguard or BlackRock target-date or risk-band funds) and the AI helps the family choose the appropriate state ABLE plan based on residency requirements, fees, investment options, and Medicaid-asset-test treatment.

Trustee Selection and the Letter of Intent

The single most-deferred decision in special-needs planning is trustee selection. The SNT trustee must (a) understand the SNT's distribution standard (typically "supplemental needs only" — distributions for things government benefits don't cover), (b) understand the means-test landscape (SSI's in-kind support and maintenance rule, Medicaid waiver program-specific rules), (c) have investment competence or hire a professional sub-advisor, (d) keep accurate accounting (potentially Form 1041 for tax filing if income exceeds the trust's filing threshold), and (e) survive the parents — meaning the choice of an aging-out-of-relevance sibling or family friend creates a future succession problem.

The AI's trustee-selection memo runs through the standard candidate types: individual trustee (sibling, cousin, family friend — low cost, high relationship continuity, succession risk), corporate trustee (bank or trust company — high cost, expertise, longevity, low relationship continuity), professional independent trustee (independent firm specializing in SNTs — middle cost, expertise, succession via firm not individual), and co-trustee structures (individual + corporate, individual + professional). For each, the memo lists upfront costs, ongoing fees (typically 0.7-1.5% of trust assets for corporate, 0.4-1.0% for professional independent, modest hourly for individual), expertise level, succession path, and the recommended choice based on trust size and family situation.

The letter of intent (LOI) is the parents' love letter to the future trustee. It is not a legal document; it has no binding effect; it cannot override the trust terms; but it is the single most valuable artifact the future trustee will reference. It captures the beneficiary's medical history, current providers, daily routines, food preferences, communication style, friends and community, education status, employment status, residential setting preferences, religious and cultural observances, and the parents' values and hopes for the beneficiary's future. The AI helps the parents draft the LOI from a structured prompt template, surfaces the dozen-plus standard sections, and produces a 15-25 page document the family then refines and updates annually. The LOI is stored with the trust document, with the trustee, and with at least one family member or family friend — the redundancy matters because the LOI's value is in its accessibility at the moment of transition.

The Integrated Memo, the Attorney/Coordination Handoffs, and the Reg BI File

The deliverable is one document for each engagement path: the divorce-and-asset-division memo (after-tax-equivalence table, QDRO mechanics, IRA §408(d)(6) transfer mechanics, Social Security ex-spouse analysis, IPS rewrite redline, post-decree beneficiary update list) or the special-needs planning memo (SNT funding plan, ABLE coordination plan, trustee selection recommendation, LOI draft, annual review schedule). Each integrates with the broader practice: divorce work cross-references the IPS update (L2 Ch5 L2), the Roth conversion screen (L3 Ch2 L1) if the post-divorce tax-bracket profile creates a new conversion window, the beneficiary audit (L3 Ch5 L2) post-decree; special-needs work cross-references the advanced vehicle decision tree (L3 Ch5 L3) for trust structure decisions and the estate gap audit for funding integration.

The advisor's role ends at the model and the handoff. The QDRO drafting, the SNT drafting, the trust amendments, the marital settlement agreement language — all live with the family-law attorney and the SNT-experienced estate attorney. The Reg BI file documents the alternatives considered, the recommendation rationale, the fee-impact disclosure (post-divorce AUM changes; SNT funding may change the advisor's billable book), the Marketing Rule disclosure on any AI-capability claim, and the CCO signoff under FINRA Rule 3110. The Smarsh or Global Relay archive captures the AI artifact chain (prompts, outputs, edits, signoffs) under FINRA Rule 4511 and SEC Rule 204-2.

Annual Review Cadence and Life-Event Triggers

Both engagements require ongoing maintenance that the AI workflow can systematize across the book. The divorce engagement triggers a recurring annual review of the post-decree IPS, the Social Security claim status (the 2-year-after-divorce finality clock, the future survivor-benefit calculation if the ex dies first), the QDRO funded account if it was the alternate payee, the beneficiary forms across every account (re-checked annually for the first three post-decree years given the frequency of overlooked updates), and the year-end tax-planning coordination that may differ post-decree. The AI's cadence: a Q1 mailing summarizing the prior year's tax filing, a Q3 mid-year IPS check, a Q4 year-end tax-planning review. Each touchpoint is a Reg BI documentation event.

The special-needs engagement triggers annual review of the SNT investment policy (drift management, distribution-rate sustainability against the beneficiary's needs), the ABLE-account contribution maximization including the ABLE-To-Work supplement if the beneficiary's earned income changed, the LOI update (annually refreshed with the beneficiary's current providers, routines, and preferences), the SSI/Medicaid means-test status review (any beneficiary-asset accumulation outside the protected vehicles), and the SECURE 2.0 §529-to-Roth eligibility tracking if the household has a 529 for the beneficiary. The AI's cadence: a fixed-date annual review tied to the trust anniversary, with mid-year touchpoints for ABLE contribution timing and any Medicaid waiver renewal deadlines.

Key Takeaways

• The after-tax-equivalence table is the first deliverable in divorce planning. Pre-tax dollar-equivalent MSAs routinely produce 20-35% after-tax inequity. Holistiplan extraction of basis from 1099-Bs, Form 5498 for retirement contribution history, Form 8606 for after-tax IRA basis, and the §121 residence exclusion are the inputs.
• QDROs under IRC §414(p) split ERISA-governed plans tax-free. The §72(t)(2)(C) exception lets the alternate payee take a cash QDRO distribution before 59½ without the 10% penalty — a one-time window that evaporates the moment funds roll to an IRA.
• IRA splits use IRC §408(d)(6), not a QDRO. The transfer must be pursuant to a divorce or separation instrument and is tax-free. Distinct from §408(d)(2) and §72(e)(8) which govern the backdoor-Roth pro-rata rule.
• Social Security ex-spouse benefit requires 10+ year marriage, claiming spouse age 62+, unmarried at claim, divorce final for 2+ years. Pays up to 50% of ex's PIA at FRA, no delayed retirement credits, claiming-spouse-independent of ex's filing status. Cross-reference L3 Ch4 L1 for integrated claiming memo.
• Third-party SNT vs first-party SNT distinction matters. First-party under 42 USC §1396p(d)(4)(A) requires Medicaid payback at death; third-party (parents' funds) does not. The recommendation depends on funding source.
• ABLE under IRC §529A is the beneficiary-owned daily-expense bucket. 2026 contribution $19,000 plus ABLE-To-Work supplement; $100K of ABLE assets excluded from SSI asset test. State-by-state plan choice matters.
• Trustee selection is the single most-deferred decision. Individual, corporate, professional independent, or co-trustee — each with cost, expertise, succession, and relationship trade-offs. The AI memo runs the candidate types.
• The letter of intent is the parents' love letter to the future trustee. Not legally binding, but the most valuable trustee artifact. The AI helps draft from structured prompt; the family refines and updates annually.
