Equity vs. Common Law — Why the Forum and the Framing Matter
(And why nearly every commercial dispute can be reframed as a trust matter)
Many legal minds know the rules of common law and the vast statutory overlay that has replaced much of it in modern courts. Fewer truly grasp equity — yet equity remains the highest form of jurisprudence in our system when properly invoked.
If you don’t know the differences, you will keep fighting in the wrong arena.
1. The Three Realms of Our Legal System
- Common Law – The original “law of the land” in England and early America. Deals with legal rights, legal title, and damages. Remedy is money or possession.
- Statutory Law – Legislative overlay; codifies and modifies common law. Enforced in public courts of law, primarily on the legal side.
- Equity – Administered in the court of chancery, dealing with trusts, fiduciary duties, conscience, and fairness. Acts in personam (on the person) rather than in rem (on the thing).
Key Principle: Where law and equity conflict, equity prevails.
- Case Law: United States v. Union Pacific R. Co., 160 U.S. 1, 50–51 (1895) — “Whenever a conflict arises between the principles of law and equity, the rules of equity will prevail.”
- Doctrinal Source: 1 Story, Commentaries on Equity Jurisprudence § 64 — “Equity acts upon the person, compelling him to perform according to the dictates of conscience.”
2. The Nature of Equity
Pomeroy’s Equity Jurisprudence, § 157:
“An equitable estate or interest is the right in property recognized and enforced by courts of equity… Legal estate is the shadow; equitable the substance.”
Equity recognizes two simultaneous estates in the same res (thing):
- Legal title – held by the trustee or nominal owner.
- Equitable title – held by the beneficiary, giving them the right to use and enjoy the property.
Case Law: Payne v. Hook, 74 U.S. (7 Wall.) 425, 430 (1868) — “A court of equity acts upon the person… the absence of a complete and adequate remedy at law is the criterion which determines whether equity will interfere.”
Maxim: Equity regards substance rather than form. This means if the conduct of the parties creates a fiduciary relationship, equity will treat it as a trust even without a formal declaration.
3. Trusts Arise by Conduct
Austin Wakeman Scott, The Law of Trusts (1939):
“The trust relationship is the foundation upon which the law of the United States rests.”
Under equity:
- Whenever one person holds property or power for the benefit of another, a trust arises.
- This can happen without a written instrument — by operation of law based on conduct.
- Courts of equity can declare a constructive trust where one party is unjustly enriched at another’s expense.
Case Law:
- Beatty v. Guggenheim Exploration Co., 225 N.Y. 380, 386 (1919) (Cardozo, J.): “A constructive trust is the formula through which the conscience of equity finds expression.”
- Sears v. Sears, 77 Ill. App. 2d 318, 322 (1966): “A trust will be implied whenever the circumstances are such that the person holding legal title cannot in good conscience retain the beneficial interest.”
4. Why Statutory Lawyers Often Miss This
Statutory practice trains you to:
- Apply codes and regulations.
- Argue based on legal title and statutory rights.
- Seek damages or statutory remedies.
But equity is a different forum with different remedies:
- Specific performance – compelling an act.
- Injunction – stopping an act.
- Accounting – compelling disclosure.
- Restitution/Rescission – restoring the parties to their original positions.
Law Review: Ames, The Origin of Uses and Trusts, 21 Harv. L. Rev. 261 (1908) — explains that equity’s jurisdiction over trusts has always been separate from, and superior to, the law side in matters of conscience.
5. How to Express a Commercial Matter as a Trust
Every commercial matter involves:
- A res (property, money, rights).
- A party with control or custody of it (trustee).
- A party intended to benefit (beneficiary).
If a fiduciary duty exists — by contract, law, or conduct — it’s a trust in equity.
Example:
- Bank deposit: Legal title to the money passes to the bank (trustee), but equitable title remains with the depositor (beneficiary). (Bank of Marin v. England, 385 U.S. 99, 101 (1966))
- Corporate officer: Holds assets in trust for shareholders. (Guth v. Loft, Inc., 5 A.2d 503, 510 (Del. 1939))
- Government officer: Holds public office in trust for the people. (Trist v. Child, 88 U.S. 441, 450 (1874))
6. The Conflict in Court
If you try to enforce equitable rights in a public, statutory court of law:
- The judge is sitting on the law side.
- They will look for legal title and statutory authority.
- Your equitable rights will be ignored unless you first invoke the equity side of the court.
Competent Process:
- Identify the trust relationship and your standing as beneficiary.
- Serve private in personam notice to the trustee.
- Petition in equity — often in camera (in chambers) — where your unalienable rights are cognizable.
- Use equitable remedies to compel performance or restitution.
7. Why This Will Never Be Outdated
Some say equity and trust doctrine are “outdated” and replaced by modern statutes. That is a misunderstanding.
Equity is not merely an old English custom — it is the codification of God’s law of conscience into human legal systems.
Biblical Foundations of Equity:
- Equity will not suffer a wrong without a remedy — Isaiah 1:17 (“Seek justice, correct oppression…”).
- Equity acts in personam — Jeremiah 31:33 (“I will write my law on their hearts…”).
- He who seeks equity must do equity — Matthew 7:12 (“Do unto others as you would have them do unto you…”).
Because equity is grounded in the eternal law of right and wrong, it cannot be repealed by statute. Legislatures can change public codes, but they cannot erase the jurisdiction of conscience — it is the foundation stone of the legal system itself.
As Scott rightly said, the trust relationship is the foundation of the United States system. And a foundation cannot be “outdated” any more than gravity can expire. You can ignore it at your peril, but you cannot remove it without collapse.
