Contract Law in Bulgaria

No. Bulgarian law does not generally require contracts to be in Bulgarian — parties are free to choose the language of their agreement. However, if a contract may need to be enforced before Bulgarian courts or submitted to a Bulgarian authority, a certified Bulgarian translation will be required. We recommend drafting bilingual contracts (English and Bulgarian) for agreements with Bulgarian counterparties, with a clear provision specifying which version prevails in case of discrepancy.

Yes. Bulgaria has implemented the EU eIDAS Regulation, which gives electronic signatures legal effect across the EU. A qualified electronic signature (QES) has the same legal effect as a handwritten signature under Bulgarian law. Advanced electronic signatures (AES) are valid for most commercial contracts. Simple electronic signatures (a scanned signature or email acceptance) are valid for most purposes but may carry evidential limitations. We advise on the appropriate signature method for each contract type.

Yes, in most commercial B2B contracts — parties are free to choose the governing law under EU Rome I Regulation (Regulation 593/2008), which applies in Bulgaria. However, choosing English law does not displace mandatory provisions of Bulgarian law that apply regardless of governing law — particularly in employment, consumer, and competition law contexts. We review foreign-law contracts from a Bulgarian mandatory law perspective as part of our contract review service.

The remedies for breach of contract under Bulgarian law are: specific performance (compelling the breaching party to perform), damages (compensation for loss caused by the breach), and termination with damages where the breach is material. The Bulgarian Obligations and Contracts Act governs remedies. Damages claims require proof of loss — Bulgarian courts do not award punitive damages. Our lawyers advise on remedy strategy and, where necessary, represent clients before Bulgarian courts or arbitration tribunals.

Bulgarian civil court proceedings for contract disputes typically take 1–3 years at first instance, with appeals adding further time. For straightforward debt claims, an accelerated procedure (заповедно производство) is available — allowing a payment order to be obtained within weeks. For cross-border or high-value disputes, international arbitration often provides a faster and more predictable alternative. We advise on the most efficient dispute resolution route for each situation.

Under Bulgarian law, contracts can in principle be formed verbally — there is no general requirement of written form for commercial agreements. However, the absence of a written contract makes proof of the agreed terms extremely difficult if a dispute arises. Certain specific contracts must be in writing — notably real estate transactions (which require notarization), and certain IP assignments. We always recommend written contracts for all commercial relationships, regardless of the parties’ level of trust.

Yes. A director of a Bulgarian company can sign contracts electronically from any location in the world using a qualified electronic signature, or by granting a Power of Attorney to a representative who signs on their behalf. Most commercial contracts between businesses do not require notarization — only specific transactions (share transfers, real estate, certain guarantees) need notarized signatures. We advise on the signature requirements for each contract type.

The general limitation period for contractual claims under Bulgarian law is 5 years from the date the claim became due. For certain claims — trade receivables between merchants — a shorter 3-year period applies. Claims not pursued within the limitation period become time-barred and unenforceable. We advise on limitation periods as part of our contract review and dispute advisory service.
