Mullane v. Central Hanover Bank & Trust: The Notice Standard

In Mullane v. Central Hanover Bank and Trust Co., 339 U.S. 306 (1950), the Supreme Court held that before a court can extinguish someone’s property rights, the notice given to that person must be “reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections.”¹ Newspaper publication alone is not enough when the affected people’s names and addresses are already known. That single sentence has governed due process notice in American law for more than seventy years, reaching well beyond trust accountings into class actions, tax sales, evictions, and the still-open question of service by email and social media.

What the Case Was About

Under New York’s Banking Law, a trust company could pool the assets of many individual trusts into a single common investment fund.² Central Hanover did exactly that. Every few years, it petitioned a New York Surrogate’s Court to approve its management of the fund, and once the accounting was approved, the bank was shielded from future claims by any beneficiary about how it had handled the money during that period.

The only notice the statute required was a single newspaper publication at least twenty days before the hearing.² The notice listed the trust company, the fund, and the participating estates. It was not mailed to anyone. Charles Mullane, appointed as special guardian to represent beneficiaries who did not otherwise appear, argued that publication-only notice violated the Fourteenth Amendment’s Due Process Clause, because the bank had the names and addresses of many beneficiaries in its own files.³ The New York courts rejected the challenge. The Supreme Court reversed.¹

The Reasonably Calculated Standard

The rule is deceptively simple. Before a court proceeding can permanently affect someone’s property, the method used to notify that person must be one that a party genuinely wanting to inform them would reasonably choose.¹ The standard does not demand perfection. Not every person must actually receive the notice. What matters is whether the chosen method was a sincere attempt rather than a formality designed to check a procedural box.

The Court weighed the state’s interest in efficiently resolving trust accountings against each beneficiary’s interest in protecting a financial stake.¹ New York had a legitimate reason to give trustees a clean slate through periodic court approval. But that administrative goal could not justify a method almost guaranteed to fail. The bank regularly mailed income checks and tax documents to the same beneficiaries, so the claim that a letter was too burdensome did not hold up.

That practical framing is why the opinion has aged well. The test always asks the same question about what a reasonable person actually trying to reach someone would do, and it scales naturally to new technologies and situations.

When Mail Is Required and When Publication Will Do

For beneficiaries whose names and addresses appeared in the bank’s records, newspaper publication was flatly unconstitutional as the sole form of notice. At minimum, the trustee had to send ordinary mail to the addresses on file.¹ The cost of postage was trivial compared to the risk of stripping someone of property rights they never knew were at stake.

The Court did not kill publication outright, though. For beneficiaries whose identities or addresses the trustee genuinely could not discover, including people with future or contingent interests that might never vest, publication remained constitutionally acceptable.¹ When there is literally no better option, the Constitution does not demand the impossible.

Publication is not a shortcut for parties who could be found with some effort. Before falling back on newspaper notice, the party seeking the court order must conduct a diligent search. That means honest, reasonable efforts under the circumstances to locate the interested party’s name and address. It does not require exhausting every conceivable method, but a party that skips obvious sources of information, like its own business records, cannot rely on publication.

The Reasonably Ascertainable Extension

Mullane drew the line between known and unknown parties, but the Supreme Court later pushed the boundary outward. In Mennonite Board of Missions v. Adams, the Court held that actual notice is required for anyone whose name and address are “reasonably ascertainable,” even if the party initiating the proceeding has not already looked them up.⁴ That case involved a tax sale where the county did not notify a mortgagee whose interest appeared in public land records. The Court rejected the argument that a sophisticated lender should have monitored tax payments on its own.

The practical effect is significant. The duty to provide actual notice reaches beyond names already sitting in a file cabinet. If a reasonable search of accessible records, like property filings, court dockets, or government registries, would reveal the person’s identity and address, that person must be contacted directly.

What the Notice Itself Must Say

Getting the delivery method right is only half the equation. The notice must reasonably convey the required information and afford a reasonable time for those interested to appear.¹ A letter that arrives on time but says nothing useful fails just as badly as one that never arrives.

An adequate notice identifies the court, describes the proceeding and what rights or property are at stake, explains how the recipient can respond, and gives enough lead time to consult a lawyer and prepare. Sending a notice the day before a hearing defeats the purpose, because the right to be heard means nothing without a realistic window to exercise it. The New York statute required twenty days between publication and the hearing, and the Court’s concern was not with that timeframe but with the fact that the notice never reached the people who needed it.

How Later Cases Sharpened the Rule

The reasonably calculated standard has been tested repeatedly since 1950, and each major case shows what it requires when the facts change.

Greene v. Lindsey (1982)

Kentucky allowed landlords to serve eviction notices by posting them on tenants’ doors. In one public housing complex, children and other residents routinely tore the notices down before tenants saw them. The Supreme Court held that this method violated due process because the process servers themselves knew the notices were “not infrequently” removed.⁵ Mailing the notice would have been a simple alternative.

Eisen v. Carlisle and Jacquelin (1974)

This case applied Mullane to class actions under Federal Rule of Civil Procedure 23. The class included roughly 2.25 million identifiable members whose addresses could be determined from brokerage records. The Supreme Court held that individual notice by mail to each identifiable member was required, and the trial court could not substitute publication because mailing was expensive.⁶ The cost fell on the plaintiff and could not be shifted to the defendant before a ruling on the merits.

Dusenbery v. United States (2002)

A federal prisoner challenged the forfeiture of cash seized during his arrest, arguing he never personally received the notice the FBI mailed to the prison. The Supreme Court held that certified mail sent to a federal prison with established mail-handling procedures satisfied due process, even if the prisoner never saw the letter.⁷ Due process requires a reasonable attempt at actual notice, not guaranteed delivery.

Jones v. Flowers (2006)

Arkansas sent certified letters to a homeowner about a pending tax sale, but both letters came back unclaimed because no one signed for them. The state then published a notice and eventually sold the property. The Supreme Court held that when a government knows its mailed notice failed, due process requires additional reasonable steps if practicable.⁸ The Court pointed to straightforward alternatives: resend by regular mail (which needs no signature), post the notice on the front door, or address it to “occupant.” The government did not have to hunt through phone books, but it could not shrug at a returned envelope and proceed to sell someone’s house.

Email, Social Media, and Digital Notice

Mullane was decided when the mail was the most reliable way to reach a known person. The standard’s flexibility has allowed courts to adapt it, though the law on digital service is still developing case by case.

Federal rules that authorize electronic filing of court documents do not extend to service of process.⁹ Serving the initial summons and complaint that drags someone into a lawsuit remains governed by Federal Rule of Civil Procedure 4. Individual courts have authorized service by email or social media in specific cases where traditional methods failed. A New York trial court in 2015 permitted service through Facebook when the plaintiff could not locate the defendant’s physical address, and federal courts have authorized email service where defendants actively evaded personal delivery. These rulings treat digital methods the way Mullane treated newspaper publication: alternatives permitted by necessity, not first choices.

In class action notice, courts regularly approve targeted digital advertising, including social media banner ads tailored to the class, as a supplement to direct mail for identifiable members. The analysis mirrors Mullane’s balancing test. For identifiable class members with known addresses, digital notice supplements but does not replace individual mail.

If You Were Never Properly Notified

If a court enters a judgment against someone who never received constitutionally adequate notice, that person is not necessarily stuck with the result. Under Federal Rule of Civil Procedure 60(b)(4), a party can ask the court to set aside a judgment that is void, and a judgment entered without proper notice is a textbook example.¹⁰ The motion must be filed within a “reasonable time,” but unlike other grounds under Rule 60, no fixed one-year deadline applies to void-judgment claims.

There is no perpetual right to challenge on voidness grounds, however. Once you learn about the judgment, you cannot sit on the information indefinitely. State courts have their own procedural equivalents, and the specific time limits vary. Beyond a motion in the original court, Rule 60(d) preserves the power to bring an independent lawsuit to undo a judgment obtained through constitutionally deficient notice. That path is more involved and typically reserved for situations where the original court’s procedures are inadequate.

Inadequate notice does not merely create an appealable error. It goes to the court’s fundamental power to bind the absent party, so a judgment entered against someone who was never properly notified stands on shaky ground from the moment it is entered, and the tools to challenge it remain available long after the ordinary window for appeals has closed.
