The предварителен договор (preliminary contract) is a legally binding agreement under Bulgarian law that commits both buyer and seller to complete a property transaction on specified terms. Unlike an option to purchase, the preliminary contract obliges both parties — either can compel the other to finalise the sale through the courts if the other party refuses. It is the standard first formal step in Bulgarian property transactions.
A typical preliminary contract sets out the purchase price, payment schedule, property description, conditions precedent (e.g. planning permit verification, mortgage clearance), and a long-stop date for signing the notarial deed. A deposit of 10% of the purchase price is customary and serves as security for both parties' performance.
Under Bulgarian law, if the buyer withdraws without legal justification, the seller retains the deposit. If the seller withdraws, they must return double the deposit to the buyer. This symmetric penalty regime encourages both parties to complete the transaction rather than speculate on price movements between signing and completion.
Preliminary contracts should be reviewed by a Bulgarian property lawyer before signing. Key issues include verification that the seller actually owns the property (via a Property Registry excerpt), confirmation that the property has no encumbrances, and checking that planning permissions are in order for new builds. A lawyer can also advise on tax efficiency, particularly for corporate buyers.
Some preliminary contracts are notarially authenticated, which gives them additional evidentiary weight and the ability to directly enforce specific performance (реализиране на предварителен договор) without a separate court action. Non-notarised preliminary contracts are still legally binding but may require a more involved court process if the other party defaults.
Key Facts

| Specific performance | Either party can force completion via Art. 19(3) ЗЗД court action |
| Notarisation | Optional but strengthens enforceability |
| Review essential | Property Registry excerpt and planning status must be checked before signing |
Frequently Asked Questions
Is the preliminary contract the same as a reservation agreement?
No. A reservation agreement (резервационен договор) is typically a short, informal document with a small reservation fee, used to take a property off the market while due diligence is conducted. The предварителен договор is a full legal commitment with a substantial deposit. Do not confuse the two — the preliminary contract has much more significant legal consequences.
Can I register a preliminary contract with the Property Registry?
Yes. A notarially authenticated preliminary contract can be registered with the Property Registry, creating a public notice of your purchase right. This protects the buyer against the seller subsequently selling or mortgaging the property to a third party.
What happens if the long-stop date passes without completion?
If neither party has invoked the penalty provisions or demanded specific performance, the preliminary contract may lapse. To prevent this, include a mechanism for extending the deadline by mutual agreement, and keep track of the long-stop date carefully.
