A contract is a legally binding agreement between $2$ or more parties outlining their relationship terms.
The $6$ essential elements for a valid contract are:
- Offer: A clear proposal by the offeror to the offeree on specific terms.
- Acceptance: Unmodified agreement to the terms, creating a "meeting of the minds."
- Consideration: Something of value (money, goods, services) exchanged between parties.
- Intention/Awareness: Mutual understanding that the agreement is legally binding.
- Capacity: Legal ability to enter agreements, typically requiring a minimum age of $18$ years and mental competency.
- Legality: The purpose of the contract must be lawful and comply with jurisdiction statutes.

Expressed Contracts: Terms are explicitly stated either orally or in writing (e.g., an apartment lease).
Implied Contracts: Formed through actions or conduct.
- Implied-in-Fact: Conduct suggests intent (e.g., ordering food at a restaurant implies payment).
- Implied-in-Law (Quasi-Contracts): Imposed by law to prevent unjust enrichment (e.g., compensation for emergency medical assistance).

Conditions: Fundamental terms of the contract.
Warranties: Assurances regarding quality, compliance, and originality.
Innominate Terms: Terms that are neither conditions nor warranties; remedies for breach depend on the significance of the violation.
Common Clauses:
- Timeline and Milestones: Start/end dates and deadlines.
- Payment Terms: Details on costs, invoicing, and late penalties.
- Confidentiality: Often referred to as a Non-Disclosure Agreement.
- Force Majeure: Excuses performance due to unforeseen events like natural disasters.
- Indemnification: Agreement to compensate for losses incurred from specific claims.

Factors that undermine validity and may render a contract void or voidable:

Misrepresentation: False statements of fact (classified as fraudulent, negligent, or innocent).
Duress: Coercion or threats that compromise free will.
Undue Influence: Exploitation of power or trust to gain unfair advantage.
Mistake: Erroneous beliefs about fundamental facts (mutual, unilateral, or common).
Illegality: Contracts violating legal statutes or public policy.

Performance: May be complete or substantial (minor deviations).
Agreement: Mutual decision to end the contract (express or implied).
Breach: Failure to meet obligations (material or minor).
Frustration: Unexpected, uncontrollable events making performance impossible.
Lapse of Time: Failure to perform within specified durations.
Operation of Law: Automatic discharge due to death, bankruptcy, or changes in law.
Conditions: Precedent (must occur before duty arises) or Subsequent (terminates duty upon occurrence).

Damages:
- Expectation Damages: For opportunity loss.
- Consequential Damages: Result-based losses.
- Liquidated Damages: Pre-determined amounts specified in the contract.
- Nominal Damages: Acknowledgment of breach without substantial proof of loss.
Specific Performance: Court order to fulfill obligations, typically used for unique items like real estate.
Injunctions: Mandatory (order to act) or Prohibitory (order to refrain).
Rescission: Cancellation to return parties to their pre-contractual positions.

This doctrine stipulates that only parties to a contract have legal rights and obligations under it.
Third parties generally cannot enforce terms or be held liable for obligations.
Historically established in cases such as Price v. Easton ( $1833$ ) and Tweddle v. Atkinson ( $1861$ ).
