7.5 Protecting Income and Assets Through Marriage, Divorce & Death
Key Takeaways
- Nine community property states treat property acquired during marriage as owned equally by both spouses, while equitable distribution states divide marital property fairly but not necessarily equally — and in both systems separate property loses its character when commingled or titled jointly, a process called transmutation.
- Transfers of property between spouses or incident to divorce are non-taxable under IRC §1041, but they carry basis over, so a divorcing spouse who accepts a low-basis concentrated stock position and a spouse who accepts an equal amount of cash have not received equal after-tax value.
- For divorce agreements executed after December 31, 2018, alimony is neither deductible by the payor nor includible by the recipient under the Tax Cuts and Jobs Act, which permanently reversed the pre-2019 treatment and reshaped negotiation leverage.
- A third-party-settled discretionary trust with a spendthrift clause is the strongest protection against a beneficiary’s future divorcing spouse, whereas a self-settled trust and any account the beneficiary can compel a distribution from are far weaker.
- A surviving spouse can typically assert an elective share against the deceased spouse’s estate — commonly one-third of an augmented estate that reaches beyond probate assets — so disinheriting a spouse requires a valid marital agreement, not merely a will provision.
7.5 Protecting Income and Assets Through Marriage, Divorce & Death
The official content outline lists "income and asset protection strategies in marriage, death, and divorce" as a distinct knowledge statement inside the Risk Management and Asset Protection section. It belongs there because for most affluent families, divorce and death are statistically far more likely to move wealth than a lawsuit is. The creditor who takes half a family's assets is usually a former spouse.
1. Two Marital Property Systems
Community Property (9 states)
Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. Property acquired during the marriage by either spouse's labor is owned one-half by each spouse from the moment of acquisition. Separate property is what each spouse brought in, plus gifts and inheritances received during the marriage.
Community property carries an enormous and frequently tested estate tax advantage: at the first death, the entire community — both halves, not just the decedent's — receives a full basis step-up under IRC §1014(b)(6). A $20,000,000 community property portfolio with a $4,000,000 basis gets a complete $20,000,000 basis at first death. The same portfolio held jointly in an equitable distribution state steps up only the decedent's half. Alaska, Tennessee, South Dakota, Florida, and Kentucky offer elective community property trusts that let residents of common-law states capture this double step-up.
Equitable Distribution (the remaining states)
Marital property is divided fairly, which may or may not be equally, considering marriage length, each spouse's contribution including homemaking, earning capacity, age and health, and the standard of living established. Separate property is generally excluded — but only if it stayed separate.
Transmutation — the Failure Mode That Actually Occurs
Separate property becomes marital property through:
- Commingling. A $3,000,000 inheritance deposited into the joint checking account is, after a few years of deposits and withdrawals, functionally untraceable and presumptively marital.
- Retitling. Adding a spouse to the deed of a premarital residence is usually treated as a gift to the marital estate.
- Active appreciation. In many states, appreciation in separate property attributable to the efforts of either spouse — running the premarital business — becomes marital, while passive market appreciation stays separate.
- Marital funds improving separate property. Paying down the mortgage on a premarital home from joint income creates a marital interest.
The operational rule: an inheritance or premarital asset stays separate only if it is held in a separately titled account, never commingled, and traceable through documentation. This is a bookkeeping discipline, and advisors who set it up at the start of a marriage prevent the problem entirely.
2. Premarital and Postmarital Agreements
A properly executed marital agreement is the single most effective wealth protection tool available to a family with an heir who is marrying.
Enforceability requirements — broadly consistent across states, and every one of them is a place agreements fail:
- Written and signed voluntarily by both parties
- Full and fair financial disclosure by both parties — the most common ground for invalidation
- Independent counsel for each party, or a knowing, documented waiver
- Adequate time before the wedding — an agreement presented days before the ceremony invites a duress claim
- Not unconscionable at execution, and in some states not unconscionable at enforcement
A postnuptial agreement does the same work after the wedding, but courts scrutinize it more heavily because the parties are already in a confidential relationship and the leverage dynamics differ.
What a marital agreement should address for a business-owning family: characterization of the business and its appreciation, whether active appreciation is marital, the valuation methodology and date to be used, treatment of specific trusts and inheritances, and — often the most valuable clause — a waiver of any claim to voting equity in the family enterprise.
3. Trust Design Against a Beneficiary's Divorce
The parent's question is: how do I leave money to my child without leaving it to my child's future ex-spouse?
| Structure | Protection Level | Why |
|---|---|---|
| Outright bequest | None | Becomes the child's property, subject to commingling and, in some states, to equitable distribution |
| Trust with mandatory income and ascertainable withdrawal rights | Weak | Courts can treat a compellable distribution as a marital resource |
| Third-party discretionary trust with a spendthrift clause | Strongest | The beneficiary cannot compel a distribution, so there is no property interest for a divorce court to divide |
| Self-settled trust (beneficiary funds it) | Weak | Most states disregard self-settled spendthrift protection, and even DAPT states carve out spousal and child support claims |
Design details that carry the weight: a fully discretionary standard rather than a mandatory or ascertainable one, an independent trustee rather than the beneficiary as sole trustee, a spendthrift clause, and situs in a jurisdiction with favorable law. Note that even the strongest domestic asset protection trust statutes except claims for spousal and child support — asset protection planning does not defeat a support order.
4. Tax Mechanics of Divorce
IRC §1041 — Non-Recognition with a Sting
Transfers between spouses, or incident to divorce (generally within one year of the end of the marriage, or related to its cessation within six years), produce no gain or loss and transfer carryover basis.
Worked example. The marital estate holds $5,000,000 of cash and $5,000,000 of founder stock with a $200,000 basis. On paper this is an even split. In substance it is not: the spouse taking the stock holds a $4,800,000 embedded gain worth roughly $1,142,000 of tax at 23.8%. Their true after-tax value is about $3,858,000 against the cash spouse's $5,000,000. Every division of a marital estate must be modeled after-tax and after embedded gain, and this is a recurring exam scenario.
Alimony After TCJA
For any divorce or separation agreement executed after December 31, 2018, alimony is not deductible by the payor and not includible by the recipient. Pre-2019 agreements retain the old treatment unless modified with an express election to adopt the new rules. This removed a genuine arbitrage — the pre-2019 regime let a couple shift income from a 37% payor to a lower-bracket recipient and split the savings — and shifted negotiating leverage materially toward the recipient.
Retirement Assets
- Qualified plans require a Qualified Domestic Relations Order (QDRO) to divide. A properly drafted QDRO lets the alternate payee take a distribution without the 10% early distribution penalty, though ordinary income tax still applies — a planning window that closes once the funds are rolled into the alternate payee's own IRA.
- IRAs are divided by the divorce instrument itself, not a QDRO, through a direct trustee-to-trustee transfer. The QDRO penalty exception does not apply to IRAs.
- Non-qualified deferred compensation generally cannot be assigned, so it must be equalized with other assets.
The Post-Divorce Cleanup Checklist
Update: beneficiary designations on every retirement account and insurance policy, transfer-on-death registrations, powers of attorney and healthcare directives, revocable trust provisions, will, and any business buy-sell provisions naming the former spouse. A stale beneficiary designation overrides the divorce decree as to plan administrators in many circumstances — and this failure is common enough that it should be a standing item in every post-divorce review.
5. Death: the Surviving Spouse's Claims
A spouse cannot generally be disinherited by will alone. Most common-law states grant an elective share — frequently one-third, and in a growing number of states scaled by marriage length — computed against an augmented estate that reaches beyond probate to include revocable trust assets, certain lifetime transfers, joint property, and retirement accounts.
Waiver requires a valid marital agreement, executed with the same disclosure and voluntariness standards described above.
Two federal overlays operate independently of state law:
- ERISA requires that a married participant's qualified plan death benefit go to the spouse unless the spouse consents in writing, witnessed by a plan representative or notary. A premarital agreement cannot supply this consent, because a fiancé is not yet a spouse — the waiver must be re-executed after the wedding. This is one of the most frequently missed items in the entire blueprint.
- IRAs are not subject to the ERISA spousal consent rule in most states, so an IRA beneficiary designation naming children over a spouse is generally effective.
Community property states add a further wrinkle: a surviving spouse already owns half the community, so the elective share concept is largely unnecessary, but a decedent attempting to devise more than their half creates a widow's election problem the estate must resolve.
A divorcing couple in an equitable distribution state agrees to split a $10,000,000 marital portfolio "evenly." One spouse takes $5,000,000 of cash; the other takes $5,000,000 of founder stock with a $200,000 cost basis. Assuming a 23.8% combined federal rate on long-term capital gain, what should the advisor point out?
A wealthy client’s son is engaged. The client wants to leave $15,000,000 to the son in a way that is maximally insulated from a future divorce. Which structure best accomplishes this?
Before their wedding, a couple signs a valid premarital agreement in which the fiancée waives all rights to her future husband’s retirement benefits. He dies five years later with a $9,000,000 balance in his employer’s ERISA-covered 401(k) plan naming his children as beneficiaries. Who receives the plan benefit?
