Contract breach occurs when one party fails to meet their obligations as agreed in the contract. Under Bulgarian law, contracts have the force of law between the parties, binding them to their promises unless changed or terminated by mutual consent or legal grounds. In Bulgaria, this is regulated at the Obligations and Contracts Act (Закон за задълженията и договорите). This article provides an overview of contract breach (non-performance), its types, legal consequences, termination, compensation, penalties, deposits, and force majeure situations under Bulgarian legislation.
Types of Contract Breaches
In the case law of the Supreme Court of Cassation, issues relating to contractual non-performance (contract breaches) have been examined repeatedly, and the court has developed a consistent approach regarding the criteria for assessing the types and consequences of non-performance.
Bulgarian law distinguishes several types of contract breaches based on their nature and severity:
1. Total Non-Performance – Repudiatory breach
This occurs when the debtor fails to fulfill any part of their contractual obligation. It includes situations in which the debtor undertakes no action that corresponds to the agreed terms of the contract.
2. Defective Performance (Imperfect Performance)
This arises when the debtor performs partially or in a manner that does not comply with the agreed conditions. Defective performance may take the following forms:
- 2.1. Delay in Performance – when the performance is rendered after the contractual deadlines.
- 2.2. Partial Performance – when only part of the obligations is fulfilled, but not all.
- 2.3. Poor Performance – when the performance fails to meet the required quality standards or other contractual specifications.
Legal Consequences of Contract Breach
When a party fails to perform as agreed, Bulgarian law provides the following consequences and protections for the aggrieved party:
- Right to Claim Performance: The injured party can demand fulfillment of the obligation if possible.
- Damages: Compensation includes actual losses and lost profits directly linked to the breach. Interest on overdue monetary payments may also apply.
- Limitation and Reduction of Liability: Liability may be reduced or excluded if the breach is due to the injured party’s actions or if the injured party fails to mitigate damages.
- Non-Performance Penalty: Pre-agreed contractual penalties (неустойка) apply without needing proof of actual damage but do not exclude full compensation claims.
Termination and Annulment of Contracts
Contracts may be terminated or annulled based on legal or contractual grounds:
- Mutual Termination: Parties may agree to end the contract voluntarily through written agreement.
- Unilateral Termination: Allowed when there is a fundamental or material breach after notice and opportunity to cure the breach.
- Legal Grounds for Termination: Expiry of contract term, impossibility of performance, or breach of essential terms.
- Annulment: Contracts that violate law, lack essential elements, or contradict good morals can be annulled by court decision.
Compensation for Non-Performance
Bulgarian law grants compensation rights, including:
- Damages: Covering direct loss and lost benefits due to the contact breach.
- Interest: Statutory or contractual interest on late payments.
- Prevention of Excessive Damage: The injured party must take reasonable steps to reduce the damage; otherwise, compensation may be reduced by courts.
- Claiming Beyond Penalties: When agreed penalties (неустойка) do not cover full damages, the injured party may claim additional compensation with evidence.
Non-Performance Penalty (Неустойка) and Deposit (Задатък)
Two distinct legal tools secure contract performance:
- Неустойка (Penalty Clause):
A contractual provision fixing a predetermined sum payable for non-performance, breach, or delay. It facilitates swift enforcement as no proof of damage is needed to claim it. However, if actual damage exceeds the penalty, the injured party can claim full compensation. The penalty can apply cumulatively with damages. There is a statute of limitation of three years for claiming penalties. - Задатък (Deposit):
A legal advance payment securing the contract’s conclusion and performance. If the party who gave the deposit breaches, the other party may keep the deposit and terminate the contract unilaterally. If the receiving party breaches, the depositor may rescind the contract and claim double the deposit amount as compensation. Unlike penalties, deposits symbolize contract confirmation and commitment rather than mere penalty for contract breach.
Force Majeure (Форсмажорни обстоятелства)
Force majeure refers to exceptional, unforeseen circumstances beyond control which prevent contract performance, such as natural disasters, epidemics, war, or government measures.
- Performance obligations are suspended legally for the duration of force majeure.
- Parties typically are exempt from liability due to force majeure.
- Contracts often contain specific force majeure clauses defining notification rules, proof, and consequences.
- Extended force majeure may justify termination without penalties, preventing unfair enforcement of impossible obligations.
Steps to Enforce Rights on Contract Breach
Enforcement in Bulgaria involves procedural stages:
- Pre-litigation: Attempt amicable settlement and send formal notices to the breaching party to perform or compensate.
- Filing a Claim: Submit a lawsuit to a competent Bulgarian court, including evidence of the contract, breach, and damages.
- Court Proceedings: The court reviews, hears, and decides, possibly ordering performance or damages, depending on your claim.
- Judgment: Court issues a decision favoring the creditor if the claim is upheld.
- Obtaining a Writ of Execution: Legal basis to begin enforcement of the judgment if the debtor does not comply voluntarily.
- Engaging a Bailiff: A public or private enforcement agent executes the judgment by seizing debtor’s assets, garnishing bank accounts, or conducting auctions.
- Execution: Actual collection of owed amounts or securing performance through judicial enforcement measures, following strict procedural rules.
- Appeals: Either party may appeal judgments under procedural deadlines but enforcement can often proceed pending appeal.
Practical Implications for Businesses in Bulgaria
Bulgarian enterprises, especially those engaging in commercial contracts, should carefully draft agreements including clear provisions on breach types, penalty clauses, deposits, and force majeure conditions. Understanding legal remedies allows businesses to reduce risks, enforce contractual rights, and resolve disputes effectively.
Companies should also be aware that Bulgarian courts emphasize good faith in contract performance. Injured parties must act prudently, including mitigating damages and following proper notice and cure procedures before seeking termination or damages.
