Failure to Perform Contract: When Nonperformance Becomes a Legal Breach

Every valid agreement creates a set of contractual obligations. Performance is the act of discharging these duties. When a party fails to meet the specific standard, quantity, or timeline outlined, they have entered the realm of nonperformance. However, the law does not demand perfection in every instance; it demands compliance with the agreed-upon standards.

There is a clinical distinction between "Total Nonperformance" and "Defective Performance." Under the doctrine of substantial performance, if a party has fulfilled the essential requirements of the contract but failed on a minor, non-essential detail, they may not be in breach of contract.

Example: If a contractor builds a house but uses a different brand of pipe that is of equal quality, it is poor or divergent performance, but it may not constitute a failure to perform the contract as a whole.

The "Materiality" of the failure is the pivot point for contract enforcement.

• Material Breach: 
• A failure so fundamental that it defeats the entire purpose of the contract. It deprives the injured party of the "benefit of the bargain."
• Minor (Partial) Breach: 
• A failure to perform a non-essential part of the agreement. You can still sue for damages, but you are usually not excused from your own performance.

Usually, a late delivery is considered a minor breach. However, if the contract contains a "Time is of the Essence" clause, the timeline becomes a material obligation. In such cases, being late by even one day constitutes a full failure to perform contract duties, giving the injured party the right to terminate the agreement immediately.

In many B2B disputes, the most frequent failure is the nonpayment of funds. When a party accepts goods or services but fails to provide the contractual obligations of payment, it creates a direct path to a claim. However, the timing of the payment and any "conditions precedent" must be audited before a breach is declared.

This occurs when a party simply fails to show up or deliver the subject matter of the contract. This also includes Anticipatory Breach (or Anticipatory Repudiation), where one party clearly communicates—through words or actions—that they do not intend to perform their future obligations.

A party is not liable for failure to perform contract duties if performance has become objectively impossible.

• Impossibility: The subject matter is destroyed (e.g., the house burned down before the lease started).
• Impracticability: An unforeseen event (like a global supply chain collapse or war) has made performance excessively burdensome or expensive.

If Party A fails to perform because Party B made it impossible for them to do so, Party A is excused. This is the "Prevention Doctrine." Similarly, if the other party committed a material breach first, your duty to perform is often suspended or terminated.

The primary goal of contract enforcement is to place the injured party in the position they would have been in had the contract been performed.

• Compensatory Damages: Money to cover the direct loss.
• Consequential Damages: Money for indirect losses (like lost profits) that were foreseeable.

If the failure is material, the non-breaching party has the right to walk away. You are no longer required to keep paying or keep providing services to a party that has fundamentally failed to uphold their end of the bargain.

Most modern contracts contain a "Notice and Cure" clause. This requires the injured party to send a formal notice of the failure and provide a specific window (e.g., 10 or 30 days) for the other party to fix the mistake. If you sue before this period expires, your case may be dismissed as premature.

A clinical demand letter serves two purposes: it attempts to resolve the dispute without the "burn rate" of a full lawsuit, and it creates an evidentiary paper trail. You must document:

• The specific obligation failed.
• The date of the failure.
• The financial impact (damages).

If you continue to accept late or incomplete performance without complaining, you may be deemed to have "waived" your right to sue later. Early evaluation ensures that your rights are preserved and that you aren't inadvertently modifying the contract through your conduct.

Litigation is a terminal risk. An analytical stewardship approach determines if the nonperformance is worth the cost of a lawsuit.
