Why Equal Is Not Always Fair: Practical Challenges in Dividing Assets Among Heirs Under US Estate Law

Introduction

American estate law commonly begins with a presumption that treats children alike. Under Section 2-103 of the Uniform Probate Code (UPC), when a person dies without a will, the intestate estate passes to descendants "per stirpes" or "by representation," dividing the estate into equal shares among children or their lines. This default rule shapes a public expectation: many testators assume that dividing an estate equally among children is the fair, neutral, and litigation-proof choice. On the contrary, equal division often produces unfair, unworkable, or contested outcomes when the family's assets, caregiving history, or circumstances are not themselves equal. This article examines five recurring points of failure between equal and fair distribution under US law and sets out drafting and structural solutions for each, grounded in statute and case law.

The Legal Baseline: Freedom of Testation and Its Limits

US law is built on freedom of testation. A competent testator may generally dispose of property in any manner, including unequally among children, subject to narrow statutory protections. Two protections matter most in this context. First, the omitted or pretermitted child statutes, such as UPC Section 2-302. It protects a child born or adopted after a will's execution and not provided for, presuming the omission was accidental unless the will shows otherwise. Second, most states recognize no absolute right of a child to inherit; unlike a surviving spouse, who benefits from elective share statutes such as UPC Sections 2-201 through 2-214. As per which, an adult child in the United States has no forced heirship right. This means unequal distribution among children is legally permissible in nearly every US jurisdiction (Louisiana's forced heirship rules for certain disabled adult children under Louisiana Civil Code Article 1493 being a notable exception). The legal question is therefore rarely whether unequal division is allowed. It is whether the plan will survive family conflict, tax exposure, and practical administration.

Problem One: Equal Shares of Unequal Assets

When an estate consists of a mix of liquid assets, such as bank accounts, and illiquid assets, such as a family business, farm, or a single residence, dividing "equally" by giving each child an undivided fractional interest in every asset creates co-ownership among people who may not want to run a business or hold real estate together. Forced sale, buyout disputes, and deadlock among co-tenant siblings are common outcomes. These are often resolved through partition actions under state real property statutes, such as California Code of Civil Procedure Section 872.210 et seq., which allow any co-owner to force a judicial sale. Instead of dividing each asset equally, the solution preferred majorly is the estate plan that should divide value equally while directing specific assets to specific heirs, using an equalization mechanism. A common structure names the child active in the family business as the recipient of the business interest. This is practiced, while the other children receive offsetting value through liquid assets, a promissory note funded by the business's future earnings, or a life insurance policy held in an irrevocable life insurance trust (ILIT) under Internal Revenue Code Section 2042, which keeps the death benefit outside the taxable estate while providing liquidity precisely calibrated to equalize non-business heirs. A qualified, independent appraisal at the time of drafting, and again close to the testator's death, is essential so that "equal value" is not later disputed as a self-serving number. A related and frequently overlooked complication is the hidden tax disparity between assets that look equal on paper but are not equal after tax. Under Internal Revenue Code Section 1014, most inherited assets receive a step-up in basis to fair market value at death, eliminating built-in capital gains for the heir who receives them. Retirement accounts, by contrast, carry no such step-up; a child who inherits a traditional IRA or 401(k) must withdraw the full account within ten years under the SECURE Act's rules at 26 U.S.C. Section 401(a)(9)(H), paying ordinary income tax on every distribution. Two children who each receive "equal" one-hundred-thousand-dollar shares, one in appreciated real estate and one in a pre-tax retirement account, do not receive equal after-tax wealth. A plan that ignores this distinction produces a paper equality that dissolves the moment the accounts are liquidated. This can be resolved by modelling each major asset class on an after-tax basis before allocating shares, and where possible, direct retirement accounts to the children in the lowest income tax brackets or to a charitably inclined child who can offset the distribution, while directing basis-stepped assets such as real estate or securities to children for whom after-tax value matters more. A qualified tax advisor should run these numbers alongside the attorney drafting the instrument, since the "equal" dollar figures written into a will rarely translate into equal purchasing power once tax character is taken into account.

Problem Two: Unequal Contribution, Especially Caregiving

Families with one child who provided years of hands-on caregiving, and other children who lived at a distance, present a recurring fairness problem. Equal division ignores the caregiving child's opportunity cost, often including reduced income, delayed retirement savings, and physical and emotional labor. Courts have generally declined to create a common-law entitlement to extra compensation absent a contract or specific testamentary provision, so the burden falls entirely on the estate plan to address this proactively. This is also where equal division intersects with litigation risk. The Texas case Lipper v. Weslow, 369 S.W.2d 698 (Tex. Civ. App., Waco 1963), illustrates the danger of leaving an unequal distribution unexplained or explained only through interested parties. There, the testatrix left her estate to her two surviving children and excluded the children of a deceased son, citing estrangement in the will itself, drafted by one of the beneficiaries, who was also her attorney. The excluded grandchildren sued for undue influence and initially won at trial. The Texas Court of Civil Appeals reversed, holding there was no probative evidence that the proponent's mind was substituted for the testatrix's own, restating the governing test for undue influence as whether control was exercised over the testator sufficient to overcome her free agency and cause her to do what she otherwise would not have done. The case is frequently cited for two lessons: unequal distribution favoring an interested drafter invites scrutiny, and a stated, credible reason for unequal treatment strengthens the will's defense even when it does not eliminate a contest entirely. Resolved by compensating the caregiving child through a specific bequest, a caregiver agreement executed and paid during the parent's lifetime under a written personal care contract (recognized for Medicaid planning purposes under 42 U.S.C. Section 1396p, provided it meets fair market value and is contemporaneously documented), or a larger share justified in a contemporaneous, independently witnessed memorandum. The explanation should be drafted or reviewed by independent counsel, not the favored beneficiary, to avoid the exact fact pattern that generated litigation in Lipper.

Problem Three: Lifetime Gifts and the Doctrine of Advancement Parents frequently make significant lifetime transfers unevenly: a down payment for one child, tuition for another, none for a third. If the will is silent, the equal-division instruction typically applies to the estate as it exists at death, ignoring the lifetime imbalance entirely, unless the doctrine of advancement is invoked. UPC Section 2-109 provides that a lifetime gift is treated as an advancement against a child's intestate share only if declared as such in a contemporaneous writing by the donor or acknowledged in writing by the recipient. Absent that writing, courts will not presume an advancement, meaning the disadvantaged children receive no automatic credit for the disparity. To avoid this, one should maintain a running ledger of substantial lifetime gifts to each child, with each gift documented and, where an offset is intended, expressly labeled as an advancement against future inheritance. The will or revocable trust should then include a hotchpot clause requiring these advances to be added back notionally to the estate before calculating each child's share, with the value fixed either at the date of the gift or the date of death as the instrument specifies, since the two methods can produce materially different results, particularly with appreciating assets such as real estate or business equity.

**Problem Four: A Child With a Disability or Public Benefits Dependency **

Equal division can affirmatively harm a child who receives means-tested government benefits such as Supplemental Security Income or Medicaid. An outright equal inheritance can disqualify that child from benefits until the inheritance is spent down, since eligibility under 42 U.S.C. Section 1382(a) is asset-limited. Leaving that child's share equal in form but ruinous in substance is the clearest example of equal treatment producing an unfair, even harmful, result. Resolve it by directing that child's equal share into a supplemental or special needs trust rather than an outright bequest. A properly drafted third-party special needs trust, distinguished from the first-party self-settled trust addressed in 42 U.S.C. Section 1396p(d)(4)(A), preserves eligibility for needs-based government benefits while still allowing the trustee to pay for supplemental items not covered by those programs. This achieves numerical equality among the children's shares while making the outcome functionally fair and protective for the child who needs it most.

Problem Five: The Contest Risk Created by Explaining Inequality

Testators are often advised to explain unequal treatment "in the will" to avoid confusion. This advice requires care. Explanations that read as accusations, disparaging one child's character or choices, can themselves become fodder for an undue influence or capacity challenge, as seen in the paragraph nine explanation scrutinized in Lipper v. Weslow. To deter contests generally, many estate plans include a no-contest, or in terrorem, clause. Enforceability varies sharply by state, and this variance is itself a planning fact that must be checked against the governing jurisdiction. Florida and Indiana render no-contest clauses unenforceable by statute; Florida Statute Section 732.517 states plainly that a provision purporting to penalize a person for contesting a will is unenforceable, and an equivalent rule applies to trusts under Florida Statute Section 736.1108. California takes the opposite approach but tempers it with a probable cause exception under California Probate Code Section 21311, under which a contest brought in good faith with probable cause will not trigger forfeiture, as illustrated in Key v. Tyler, 34 Cal. App. 5th 505 (2019), and Estate of Gonzalez. Michigan similarly enforces such clauses unless the contestant had probable cause, codified at Michigan Compiled Laws Section 700.2518. New York courts, applying Estates, Powers and Trusts Law Section 3-3.5, have refused to enforce in terrorem clauses against beneficiaries who challenge a fiduciary's conduct rather than the instrument itself, as in In re Estate of Prevratil. Therefore, do not rely on a no-contest clause as a substitute for a defensible plan; confirm its enforceability in the governing state before drafting around it. Where explanations for unequal treatment are included, keep them factual, brief, and free of disparagement, and consider placing detailed reasoning in a separate, non-testamentary letter of wishes rather than the operative will, since the letter can provide context to a probate court without becoming a permanent, contestable part of the public record in the same way.

Problem Six: Blended Families and Children From Different Marriages

Equal division becomes especially fraught when children from a first marriage and a current spouse, or children from that spouse's own prior relationship, are all potential heirs. A plan that leaves everything outright to a surviving second spouse, trusting that spouse to eventually treat all children equally, has no legal enforceability once the first spouse dies; the surviving spouse may freely rewrite their own estate plan, and children from the deceased spouse's first marriage are commonly disinherited in practice, a pattern well documented in probate litigation involving second marriages. Solution lies in a Qualified Terminable Interest Property (QTIP) trust, authorized under Internal Revenue Code Section 2056(b)(7), allows the first spouse to die to provide income and, if desired, principal access to the surviving spouse during that spouse's lifetime, while irrevocably directing the remaining principal to the children from the first marriage upon the surviving spouse's death. This structure allows the testator to be fair to both the current spouse and the children of a prior relationship without relying on the surviving spouse's future goodwill, and it removes the surviving spouse's independent testamentary discretion over assets that were never truly theirs to redirect.

Structural Solutions Beyond the Will Itself

Several tools address unequal-versus-fair tension at a structural level rather than clause by clause. A revocable living trust with an independent or corporate co-trustee can hold assets under a health, education, maintenance, and support (HEMS) standard, giving a neutral fiduciary discretion to make case-by-case distributions that a rigid equal-shares will cannot accommodate. A family meeting held during the testator's lifetime, ideally with counsel present, surfaces disagreements before death rather than after, when the testator can no longer explain intent. Mandatory mediation clauses, increasingly used in trust instruments, require heirs to attempt mediation before litigating, reducing the cost and permanence of disputes. Finally, choosing a neutral, professional trustee rather than one of the children to administer a trust holding a family business or shared property removes the sibling from the position of judging their own fairness, which is frequently the flashpoint that turns a merely unequal plan into a litigated one.

Conclusion

Equal division is administratively simple and intuitively neutral, but US estate law does not require it, and rigid equality frequently produces outcomes that are unfair in substance: forced sales of family businesses, uncompensated caregiving, ignored lifetime gifts, jeopardized public benefits, and family litigation triggered by unexplained or poorly explained inequality. The statutory and case law framework, from the UPC's default equal-shares intestacy rule to the advancement doctrine under UPC Section 2-109, the special needs trust rules under 42 U.S.C. Section 1396p(d)(4)(A), and the state-by-state variance in no-contest clause enforcement, gives testators the legal tools to plan for fairness rather than mere arithmetic equality. The practical solution in nearly every contested estate traced back to unequal treatment is the same: value-based equalization instead of asset-based division, contemporaneous and independently documented rationale for departures from equality, and structural safeguards, such as neutral trustees and properly drafted trusts, that remove disputed judgment calls from the hands of the heirs themselves.
