Flat rental agreement in Bulgaria: template, essential clauses, and advice

A flat rental agreement is the written arrangement governing the relationship between a landlord, who owns the property, and a tenant who uses the home for a monthly price. Bulgarian law does not require the agreement to be notarised, but a written contract is strongly recommended. It is the main protection for both parties in a dispute over the deposit, repairs, unpaid rent, or early termination. This guide goes through the clauses a sound agreement should contain and the most common traps.

What a rental agreement is and why writing is essential in practice

Renting is a bilateral transaction: the landlord makes the property available for temporary use, while the tenant pays the agreed price and takes reasonable care of it. A verbal agreement can also be valid by law, but is extremely difficult to prove. A written contract is therefore protection, not a formality.

A good contract answers in advance the questions that otherwise cause conflict: what the rent includes, who pays the bills, when the deposit may be retained, and how the relationship ends. When comparing properties to rent in Sofia or another city, always ask whether a written agreement will be signed. A refusal is the first warning sign.

Essential clauses in a flat rental agreement

A complete agreement should contain at least:

• Parties to the agreement - full names, national identification numbers, and addresses of landlord and tenant; if the landlord acts through a representative, attach the power of attorney.
• Property description - exact address, floor, area, number of rooms, and an inventory of furniture and appliances as a separate attachment.
• Term - start and end dates; open-ended agreements are also possible, but a fixed term gives greater clarity.
• Monthly rent - amount, currency, payment date, and method, whether bank transfer or cash against a receipt.
• Deposit - amount, permitted reasons for retention, and refund deadline.
• Utilities and charges - who pays electricity, water, heating, internet, building service charges, and municipal waste fee.
• Rights and obligations of both parties, including repairs and maintenance.
• Termination terms - notice period and penalties.

It is also advisable to attach an inventory and handover report with photos showing the condition on move-in and the electricity and water meter readings. This is the document that most often resolves a dispute over the deposit.

Rental deposit: amount, retention, and return

The deposit is usually equal to one month's rent, or sometimes two for luxury or furnished properties. It guarantees damage beyond fair wear and tear and unpaid bills. It is not the "last month's rent" unless the agreement expressly says so.

The landlord may retain money from the deposit for:

• actual damage to the property or furnishings beyond normal wear and tear;
• unpaid utilities as of the move-out date;
• unpaid rent.

It is not reasonable to retain money for faded paint, a worn floor, or minor signs of normal living. The inventory and handover report with photos is therefore your strongest evidence. The agreement should also specify a deadline for returning the deposit, such as within 14 days after handover and confirmation of the bills.

Rights and obligations of tenant and landlord

A balanced contract allocates responsibilities clearly. As a general rule:

The landlord must provide a habitable property, repair defects not caused by the tenant, such as a leaking installation or faulty water heater, and avoid disturbing the tenant without notice.

The tenant must pay rent and bills on time, use the property for its intended purpose, avoid subletting without consent, and return it in the condition received, allowing for fair wear and tear.

Minor routine repairs, such as replacing a light bulb, silicone seal, or small fitting, are usually paid by the tenant, while substantial repairs fall to the landlord. Define this threshold expressly to avoid disputes. Before committing, also confirm who the actual owner is. The document checks in buying a flat without costly mistakes are relevant to renting too.

Registration, tax, and declaration of rental income

Rental income is taxable in Bulgaria. An individual landlord owes income tax on rental income with 10% recognised expenses and declares it annually. If the tenant is a company, it withholds and pays advance tax. These details do not affect the validity of the agreement, but tenants should know that a lawful contract also implies declared income, which provides an additional sign of a secure transaction.

The agreement does not have to be registered or notarised. Notarial certification does, however, provide an officially verifiable date and can make debt collection easier, so it may be a sensible investment for a higher rent.

Template, checklist, and common mistakes before signing

Use the Property agreements page to download a rental agreement template, then adapt and review it for the specific property.

Before signing, check:

• Does the name in the agreement match the property's ownership document?
• Are the floor area, furniture, and appliances described accurately?
• Are the rent amount, payment date, and method clear?
• Are the deposit amount and grounds for retention stated?
• Who pays each utility and charge?
• What is the termination notice period, and is there a penalty?
• Is there an inventory and handover report with photos and meter readings?

The most common mistakes are a missing furniture inventory, vague deposit terms, and cash payments without a receipt. Avoid them and the rental will be safer and calmer for both parties.
