Quick answer
What does principles mean?
Legal principles generally mean fundamental, underlying legal rules or doctrines that guide court decisions even when no specific law applies. In contracts, they matter because parties assume certain standards of conduct—like good faith—which may not be written down. Before signing, confirm which state's laws govern the contract.
Definitions
What is principles?
Legal Definition
Legal principles are fundamental, underlying rules that guide judicial decision-making across different areas of law. These governing doctrines establish general standards or guidelines, creating obligations or defining rights even when no specific statute applies. Practitioners often care most about whether the principle is considered common law or if it has been codified into a specific regulation.
Plain-English Translation
Think of principles like the rules for sharing toys: you must take turns and play fairly with everyone. If you ignore those basic rules, your friends won't let you play at all.
Term context
How principles shows up in legal documents
Why does it matter?
Ignoring an established principle can lead to the court refusing relief, voiding an agreement due to lack of consideration, or finding a party liable for breach of duty. The risk generally falls on the party attempting to circumvent the standard rule.
When does it matter?
Principles are invoked when a dispute arises and existing written rules fail to provide a clear answer. A court applies them at any stage, particularly during motion practice or trial, to interpret ambiguous law.
Where is it usually seen?
These concepts appear across common law courts (state and federal) and are frequently cited in contract disputes involving implied covenants of good faith and fair dealing.
Who is affected?
A plaintiff invokes a principle to argue for equitable relief when damages are inadequate. A defendant uses principles like promissory estoppel to limit the scope of liability or deny enforcement.
How does it work?
First, a party identifies an ambiguous legal issue where existing statutes do not provide guidance. Next, they argue that established common law principles—such as reasonableness or good faith—should govern the outcome. Finally, the court weighs these fundamental standards against specific facts to render judgment.

Document context
Where principles appears in documents
| Document type | Section | Why it matters |
|---|---|---|
| Governing Law Clause Choice of Law Section | Determines which jurisdiction’s legal principles apply to interpreting the agreement. | It dictates whether state common law or another body of rules controls dispute resolution. |
| Indemnification Agreement Liability Limitation Section | Governs the fundamental principles of fault and risk allocation between parties. | It establishes who bears financial responsibility when a breach or incident occurs. |
| Non-Compete Agreement Restrictions Section | Applies common law principles regarding the reasonableness and enforceability of restrictions on trade. | A court must determine if restricting your actions is legally permissible under local standards. |
| Contract wording example Plain-English meaning What to check | Implied covenant of good faith and fair dealing The law assumes you will act honestly and reasonably throughout the contract's term. Verify that performance standards are clearly defined, not just relying on 'good faith.' | The language is often vague but carries significant legal weight regarding expected conduct. |
| Contract wording example Plain-English meaning What to check | Reasonable efforts to achieve X goal The law requires you to try hard, but 'reasonable' is subjective and undefined. Replace with specific metrics: 'achieve X within 60 days using Y resources.' | Avoid standards of performance that rely on vague judgment calls. |
| Contract wording example Plain-English meaning What to check | Consistent with prevailing industry practice The law requires you to follow the general norms of your specific business field. Ask for an attached appendix listing required operational standards or compliance checklists. | This standard is entirely subjective and creates unpredictable obligations during a dispute. |
| Risky wording pattern Why it may matter What to check before signing | The agreement shall be governed by the principles of law as they exist in the state. This is too vague; it allows a court to choose rules without explicit consent. Specify the exact name of the governing state (e.g., 'State of Texas'). | Vague references to legal principles undermine enforceability. |
| Risky wording pattern Why it may matter What to check before signing | All parties agree that the obligations are reasonable and enforceable. This clause attempts to pre-judge a court's ability to enforce terms, which is difficult. Have an attorney draft this to explicitly reference established state common law. | Overly broad agreements may be struck down as contrary to public policy. |
Contract language
Common contract wording
| Contract wording | Plain-English meaning | What to check |
|---|---|---|
| Implied covenant of good faith and fair dealing | The law requires you to act honestly and reasonably throughout the contract's term. | Verify that performance standards are clear, measurable metrics, not just 'good faith'. |
| Reasonable efforts | The law requires you to try hard, but 'reasonable' is subjective and undefined. | Replace this phrase with specific, measurable actions or resources required. |
| Consistent with prevailing industry practice | The law requires you to follow the general norms of your business field. | Insist on an attached appendix listing specific, accepted operational standards. |
Red flags
Red flags to watch for
The agreement shall be governed by the principles of law as they exist in the state.
This phrasing is too vague; it allows a court to choose rules without explicit, agreed-upon consent.
What to check: Specify the exact name and full jurisdiction of the governing state (e.g., 'State of New York').
All parties agree that the obligations are reasonable and enforceable.
This attempts to pre-judge a court's ability to enforce terms, which is difficult for private parties.
What to check: Have an attorney draft this clause to explicitly reference established state common law or statutes.
The services must be performed in a manner consistent with industry principles.
This standard is subjective, allowing the receiving party to claim failure based on their own undefined perception.
What to check: Replace it with concrete standards: 'in accordance with ISO 9001 standards' or 'as outlined in Exhibit C.'
The agreement shall be governed by the principles of law as they exist.
It lacks jurisdictional specificity and creates uncertainty about which body of rules applies.
What to check: Always name a specific state or territory.
Performance must adhere to the principles of common law.
Common law varies significantly by jurisdiction, making this clause unpredictable for global businesses.
What to check: If possible, reference a specific, codified statute instead.
The parties agree to act in good faith based on industry standards.
It combines two vague concepts—good faith (conduct) and industry standards (performance)—making enforcement difficult.
What to check: Separate the clauses; define 'good faith' obligations separately from performance requirements.

Pre-signature checklist
What to check before signing
1
Confirm the governing state law explicitly.
2
Ensure definitions for vague terms like 'reasonable' are provided.
3
Check if any mandatory local laws (e.g., wage or consumer protection) override clauses.
4
Identify if the contract relies on implied covenants not explicitly stated.
5
Verify that the selection of jurisdiction is acceptable to both parties.
6
Review all standards of performance for measurable outcomes.
Party impact
How principles affects each party
| Party | What this party should check |
|---|---|
| Client/Individual | Ensure the contract does not force you into a jurisdiction or set of laws far from your home base. |
| Business Owner | Verify that performance standards are quantifiable and measurable to avoid vague claims of breach. |
| Service Provider | Confirm the contract clearly defines the standard of care expected, linking it to recognized professional guidelines. |
Comparison
principles vs similar terms
| Related term | Plain meaning | Main difference from principles |
|---|---|---|
| Implied Covenant | A duty assumed by law (e.g., good faith) even if not written in the contract. | An implied covenant is a specific *type* of principle, whereas 'principles' is the general category. |
| Governing Law | The statute or legal system that a court will use to interpret the contract. | This is the *application* of principles; it names the source code for interpretation. |
| Doctrine | An established body of legal rules or concepts used by courts (e.g., doctrine of estoppel). | A doctrine is a specific, named principle; 'principles' covers all such underlying rules. |
Missing or vague
If principles is missing or vague
If the contract fails to define legal principles, disputes often arise over who bears the burden of proof and what standard of conduct was expected. Vague language regarding performance standards allows a party to claim failure based on subjective interpretation, leading to costly litigation. Furthermore, without specifying the governing law's underlying rules, a court might apply unpredictable or unfavorable common law doctrines. Always insist that key operational requirements are defined by concrete metrics rather than abstract principles.
