Commercial Lease Agreements in Bulgaria: Legal Framework and Key Provisions

I. Legal Framework

Lease agreements in Bulgaria are governed primarily by Articles 228–239 of the Obligations and Contracts Act (Закон за задълженията и договорите, ЗЗД), supplemented — where the tenant is a trader and the lease relates to business premises — by the provisions of the Commercial Act applicable to commercial transactions. Bulgarian law does not impose a mandatory written form for the validity of a lease agreement; an oral lease is legally binding as between the parties. However, the registration requirements described below, and the practical necessity of having documentary evidence of the agreed terms, make a written agreement essential in any commercial context.

II. Essential Terms

A well-drafted commercial lease agreement should address, at minimum: the precise identification of the leased premises (by reference to the cadastral identifier, address, and area); the term of the lease; the rent and payment intervals; the permitted use of the premises; the allocation of maintenance obligations between landlord and tenant; the provisions applicable to improvements and fit-out works; the security deposit and the conditions for its return; the insurance obligations of each party; the grounds and procedure for early termination; the sub-letting and assignment restrictions; and the governing law and dispute resolution mechanism.

III. Term and Registration

Lease agreements may be concluded for any term. Agreements for a term exceeding one year are registrable in the Property Register of the Registry Agency, and — critically — a lease that is not registered may not be enforced against a third party who subsequently acquires the leased property without notice of the lease. In other words, if the landlord sells the property to a buyer who has no knowledge of an unregistered lease with a term exceeding one year, the buyer takes free of the lease and may serve a notice of termination on the tenant.

Registration also confers on the registered tenant a pre-emption right over the leased premises in the event of a sale by the landlord, provided the registered lease was concluded for a term of at least one year and is still in force at the date of the proposed sale. This pre-emption right is a significant practical protection for commercial tenants who have invested in fitting out their premises and whose business would be disrupted by a change of landlord on adverse terms.

IV. Landlord and Tenant Obligations

The landlord's primary obligations are: to deliver the premises in a condition suitable for the agreed use; to maintain the premises in that condition throughout the term; and not to interfere with the tenant's quiet enjoyment. The tenant's primary obligations are: to pay the rent on the agreed dates; to use the premises only for the agreed purpose; to maintain the premises in the condition in which they were received, ordinary wear and tear excepted; and to return the premises at the end of the term in the same condition.

The allocation of maintenance obligations between landlord and tenant is a matter of agreement. In the absence of a specific contractual provision, the Law provides that the landlord is responsible for structural repairs and the tenant for routine maintenance. In practice, commercial leases typically allocate internal maintenance to the tenant and structural and external repairs to the landlord, subject to a service charge arrangement for common areas.

V. Early Termination

A lease of definite term may be terminated early only on grounds provided by the contract or the law. Statutory grounds for early termination include: the tenant's repeated failure to pay rent; use of the premises for purposes other than those agreed; material damage caused by the tenant; and sub-letting without the landlord's consent where the contract prohibits it. The landlord must give the tenant a written notice specifying the breach and a reasonable period to remedy it before serving notice of termination, unless the breach is irremediable.

A lease of indefinite term may be terminated by either party on one month's notice. The parties may agree a longer notice period — and commercial leases typically do — but a notice period shorter than one month cannot be contracted for.
