## Breach of contract in Wyoming
Contract disputes are the most common type of business litigation. Wyoming contract law follows common-law principles supplemented by the Uniform Commercial Code (UCC) for goods.
## Elements of breach-of-contract claim
**Plaintiff must prove:**
1. **Valid contract** existed
2. **Plaintiff performed** (or excused from performance)
3. **Defendant breached** the contract
4. **Damages** resulted
## Element 1 — valid contract
**Required elements:**
- **Offer + acceptance** — meeting of minds
- **Consideration** — both sides give something
- **Mutual assent** — agreement on essential terms
- **Capacity** — parties legally able to contract
- **Lawful purpose** — not for illegal goal
**Form requirements (Statute of Frauds):**
- Real-estate contracts (sale of land)
- Contracts that can't be performed within 1 year
- Marriage-related contracts
- Sale of goods $500+ (UCC)
- Suretyship / guaranty
- ${s.name}-specific provisions
**Often need writing — but not always.**
## Types of contracts
**Express contracts:**
- Specific terms agreed

- Most common
**Implied-in-fact:**
- Conduct shows agreement
- Course of dealing
- No explicit terms
**Implied-in-law (quasi-contract):**
- Not really contract
- Equity remedy
- Unjust enrichment
- When other party benefits without paying
## Element 2 — performance / excuse
**Plaintiff must show:**
- Substantially performed obligations
- Or had legitimate reason to not perform
- Conditions precedent satisfied
- Material breach by other side excusing performance
- Frustration of purpose / impossibility
- Force majeure (if contract provides)
## Element 3 — breach
**Types of breach:**
**Material breach:**
- Goes to essence of contract
- Significantly impairs purpose
- Other party may withhold performance
- Other party may sue + recover
**Minor (immaterial) breach:**
- Doesn't go to essence
- Other party must continue performance
- May recover damages from breach
**Anticipatory repudiation:**
- Clear statement / action of intent not to perform
- Before performance due
- Allows immediate suit
- Can wait until performance time + then sue
**Substantial vs total performance:**
- Substantial = good-faith with minor variations
- Total = exact performance
- Most contracts only require substantial
## Element 4 — damages
**Most contract cases turn on damages.**
**Compensatory damages:**
**1. Expectation damages** (most common):
- Put non-breaching party in position as if performed
- Lost profits + benefits

**2. Reliance damages:**

- Hadley rule applies
**Certainty:**
- Damages provable with reasonable certainty
- Speculative damages not recoverable
- Lost profits often hardest to prove
**Causation:**
- Damages caused by breach
- Not other causes
- Proximate cause analysis
## Equitable remedies (when damages inadequate)
**Specific performance:**
- Court orders actual performance
- Used when damages inadequate
- Real estate (always unique)
- Unique goods
- Limited to feasible / appropriate cases
**Injunction:**
- Stop breach / further harm
- Mandatory + prohibitory injunctions
- Preliminary + permanent
- Discretionary remedy
**Reformation:**

## Common mistakes

- **Continuing performance after breach** — waiver risk
- **Not preserving evidence** — emails, drafts, communications
- **Missing statute of limitations** — claim barred
- **Settling without release** — multiple claims possible
- **Liquidated damages too high** — unenforceable as penalty
