Contract Law Primer

Enough contract law to read every operating agreement, subscription document, and smart-contract audit critically. Not a substitute for law school. Sufficient to know when to escalate to counsel.

1. The four elements of a valid contract

Under US common law, a contract requires four elements to be enforceable:

  1. Offer. A definite proposal to enter into an agreement on specified terms.
  2. Acceptance. Unqualified assent to the offer's terms. A counteroffer is a rejection + new offer.
  3. Consideration. Something of value exchanged by each party. Money, goods, services, or a promise to do (or not do) something. A gratuitous promise generally is not enforceable.
  4. Mutual assent + capacity. Both parties must intend to be bound, and both must have legal capacity (age of majority, mental competence, corporate authority).

Missing any element = no contract. This is the framework courts apply to every contested agreement.

2. UCC vs common law

Two bodies of contract law apply to different transactions:

Common Law

Governs services, real estate, employment, licenses. Origin: English common law, developed by courts. Modified by statute in some areas but the default framework is judge-made.

Key features: "mirror image" rule for acceptance, statute of frauds for certain agreements, strict enforcement of stated terms.

UCC Article 2

Uniform Commercial Code — governs sales of goods. Adopted in all US states with minor variations. More flexible than common law.

Key features: "battle of the forms" rule allows contracts even with mismatched terms; gap-fillers for missing terms; merchant-specific rules; warranty of merchantability implied by default.

3. The Statute of Frauds — which contracts must be in writing

Some contracts are only enforceable if in writing signed by the party charged. The categories (mnemonic: MY LEGS):

Modern digital signatures (e-signature under E-SIGN Act and UETA) satisfy the writing requirement for all of these except a small handful of state-specific exclusions (wills, family court orders).

4. Boilerplate that actually matters

Every operating agreement, subscription agreement, and services contract has a "General Provisions" or "Miscellaneous" section that most people skim. These clauses have outsized impact when things go wrong.

ClauseWhat it doesWatch for
Governing LawWhich state's law appliesDelaware for corporate; NY for financial contracts; sponsor's home state for real estate
Forum / VenueWhere lawsuits must be filedExclusive jurisdiction clause locks you into a specific court
Waiver of Jury TrialJudge-only decision, not juryCommon in commercial agreements; unenforceable in some states/contexts
ArbitrationPrivate dispute resolution outside courtsChoice of arbitrator matters (JAMS, AAA); confidential; often faster + more expensive per hour
Attorney's Fees / Prevailing PartyLoser pays winner's legal feesDefault is each side pays own; this clause changes it
NoticeHow formal notices must be deliveredCertified mail + email + physical address. Failure to comply invalidates the notice.
Merger / IntegrationPrior negotiations / discussions are excludedKills reliance on oral promises, side letters, or emails not in the final contract
AmendmentHow the contract can be changed"In writing signed by both" is standard; watch for "in writing signed by the Manager" only
SeverabilityInvalid clause doesn't kill the whole contractStandard; but pay attention to how "materially adverse" is defined
Force MajeureExcuse performance for events beyond controlPost-COVID versions specifically enumerate pandemics; watch for what's excluded

5. Breach and remedies

Not every failure to perform is a "breach" that entitles the other party to damages. The tiers:

Remedies available (varies by jurisdiction and contract):

  1. Expectation damages. Put the non-breaching party in the position they would have been in had the contract been performed. This is the default measure.
  2. Reliance damages. Reimburse expenses incurred in reliance on the contract.
  3. Restitution. Return any benefit conferred on the breaching party (unjust enrichment).
  4. Specific performance. Court orders the breaching party to actually perform. Only available for unique goods/services (real estate, custom-built assets); not available for services requiring personal skill.
  5. Liquidated damages. Pre-agreed damage amount specified in the contract. Enforceable if reasonable estimate at time of contracting; unenforceable if a "penalty."
  6. Rescission + restitution. Unwind the contract entirely, return everything to the pre-contract state.

6. Reading a securities-adjacent contract

When reviewing an operating agreement, subscription document, PPM, or smart-contract audit, apply this checklist:

7. Smart contracts and legal contracts — the alignment problem

A smart contract (code that executes on a blockchain) and a legal contract (paper signed by parties) are different things. In serious tokenized-securities structures they must reference each other:
