Complete Performance: All terms of the contract are fully satisfied without deviations, discharging the performing party's obligations.

Substantial Performance: The party fulfills enough of their obligations to warrant payment, despite minor deviations.

Divisibility of Contracts: Contracts can be divided into separate parts, each with its own performance obligations and payments, allowing partial enforcement.

Material Breach: Significant failure to perform, allowing the non-breaching party to terminate the contract and seek damages.

Minor Breach: Slight deviation that does not substantially affect the contract’s purpose, allowing the non-breaching party to seek damages while still performing their obligations.

Anticipatory Repudiation: When a party indicates they will not perform their contractual obligations before the performance is due, allowing the non-breaching party to treat the contract as breached and seek remedies immediately.

Legal Remedies (Damages):

Compensatory Damages: Aim to put the non-breaching party in the position they would have been in if the contract had been performed.

Consequential Damages: Cover indirect and foreseeable losses caused by the breach.

Punitive Damages: Punish the breaching party for egregious behavior and deter future misconduct (rare in contract law).

Nominal Damages: Acknowledge the breach when no actual loss has occurred.

Liquidated Damages: Pre-determined amounts specified in the contract to be paid in the event of a breach.

Equitable Remedies:

Specific Performance: Compels the breaching party to perform their contractual obligations, typically used when monetary damages are inadequate.

Injunction: A court order preventing a party from performing a specific act that would breach the contract.

Rescission: Cancels the contract and restores the parties to their pre-contract positions.

Reformation: Modifies the contract to reflect the true intentions of the parties.
