The most common problems do not arise at the moment of signing, but from vague clauses - a deadline with no specific date, payments tied to the calendar instead of the actual construction stage, a generic description of the property, or no effective penalty for delay. A well-drafted contract does not eliminate all risk, but it makes the risk visible, measurable and manageable.
What is a preliminary contract and what is its legal effect
A preliminary contract obliges the parties to enter into a final agreement under terms agreed in advance. If one party refuses to perform, the party in good standing may seek protection through the courts under the general rules of the Bulgarian Obligations and Contracts Act.
The notarial deed is the document that transfers ownership. A preliminary contract does not make you the owner by itself; it governs your right to require completion of the transaction under the agreed terms.
As a rule, a preliminary contract only needs to be in written form. Notarised signatures are not mandatory, but in some cases they can have practical value as additional evidence if a dispute later arises.
When a preliminary contract is used in new construction
When buying a newly built property, the preliminary contract is usually signed while the project is still under construction or before the parties are ready for final transfer. This allows the developer to secure staged financing and the buyer to reserve a specific unit under agreed commercial and legal terms.
In practice, the final transaction may be structured differently depending on the construction stage, the project sales model and the bank financing. Some deals are completed after the building reaches a later stage, while others are finalised only after commissioning. That is exactly why the preliminary contract must clearly set out the route to the final deed.
Deposit, advance payment and reservation fee - what is the difference
The deposit under Article 93 of the Obligations and Contracts Act has a specific legal effect. It proves that the contract has been concluded and secures its performance. If non-performance is caused by the party that gave the deposit, the other party may retain it. If non-performance is caused by the party that received the deposit, that party may owe the deposit back in double.
Advance payment, earnest money and reservation fee are often used interchangeably in everyday language, but not every upfront payment has the legal effect of a statutory deposit. If the wording of the contract is unclear, the dispute usually starts from there.

Clauses that must be included in the contract
The riskiest preliminary contracts are not necessarily unlawful - they are simply drafted in a way that leaves almost everything important unclear. For the buyer, that means paying now and arguing later about what was actually promised.
The most important points are the exact description of the property, the completion deadline, the payment structure, the handover standard, the permitted deviation in area, the termination conditions and the developer's liability for delay.

How to tie payments to construction progress
The most sensible structure is for payments to follow actual construction progress rather than arbitrary dates in the calendar. This reduces the risk that the buyer has already paid for a stage the project has not yet reached.
Instead of wording such as 'the second payment is due on 15 October', it is safer to agree that payment becomes due within a specified period after a particular construction stage has been duly certified. That way, if construction is delayed, the payment is delayed as well.
The exact scheme varies from project to project, but the contract should state clearly how the occurrence of each stage is evidenced, within what period payment is due, and what the consequences are if the buyer is late.
Penalty for delayed handover
A penalty clause is one of the most important protective clauses in the contract. Good practice is for the clause to be clear, easy to calculate and tied to a specific trigger date from which it starts to accrue.
There is no single mandatory percentage. The amount depends on negotiations, market practice and the individual project. The key point is that the sum should not be symbolic and should be combined with the buyer's right to terminate in the event of substantial delay.
Description of the property and handover standard
A wording such as 'apartment on the third floor' is not enough. The contract should describe the exact unit, the appurtenant parts and what exactly will be delivered at handover.
With new construction, it is good practice to attach a separate technical specification - windows, entrance door, floor screed, plumbing and electrical installations, common areas, lift, facade and everything else that matters to the final quality and scope of delivery.
Which documents to request before signing
Before signing, request at minimum a title document for the land or an established building right, a building permit, a current encumbrance certificate, and a layout or floor plan of the specific unit.
A tax valuation certificate is not a substitute for an encumbrance certificate. The tax valuation serves tax and notarial purposes, while the encumbrance certificate is the document that shows whether mortgages, attachments, claims or other registered burdens affect the land.
It is also useful to check the current legal status of the developer company and whether any registered securities may affect the project. If construction is already advanced, copies of the relevant construction certificates and recent visual evidence of progress may also be requested.
Buying directly from the developer
When buying directly from the developer, there is no brokerage commission, but that does not mean the contract is untouchable or purely standard form. On the contrary, the key clauses are negotiable, especially when they concern deadlines, payment triggers, specifications and delay liability.
A reliable developer will usually not refuse reasonable clarifications to the text when they create predictability for both parties. A refusal to provide core documents or to state a real delivery deadline is a warning sign.
What to know about registration and court protection
As a rule, the preliminary contract itself is not registered as a transfer instrument in the Property Register. If a dispute arises and a claim is filed under Article 19(3) of the Obligations and Contracts Act to have the contract declared final, the statement of claim may be registered. That registration matters in terms of enforceability against third parties.
This is an important distinction. Many buyers believe that the preliminary contract itself gives them real-property protection, but until the final transfer or a court judgment, that protection is not equivalent to the protection created by a registered notarial deed.
Costs related to the preliminary contract
As a rule, the preliminary contract does not trigger the notarial fees associated with the final transfer unless the parties additionally choose notarisation of signatures or content. The more meaningful cost is usually a legal review of the contract.
For a buyer of a higher-value property, a lawyer's review is a sensible expense. The notary certifies form and identity, but does not act as the buyer's legal advocate and does not negotiate the terms on the buyer's behalf.
Frequently asked questions
Is a preliminary contract mandatory when buying new construction?
It is not legally mandatory in every case, but in practice it is almost always used in new construction transactions because it allows the parties to agree the price, deadlines and payment structure before the final transfer is possible.
Are a statutory deposit and earnest money the same thing?
No. A statutory deposit under Article 93 of the Obligations and Contracts Act has a specific legal effect. An advance payment, earnest money or reservation fee will have consequences only according to the exact wording of the contract and does not automatically trigger repayment in double.
Can a preliminary contract be registered in the Property Register?
As a rule, not the preliminary contract itself, but the statement of claim under Article 19(3) of the Obligations and Contracts Act in court proceedings may be registered. This matters for enforceability vis-à-vis third parties.
When is the final notarial deed signed in a new construction deal?
There is no single mandatory moment for all transactions. It depends on the construction stage, the project structure and the financing. That is why the preliminary contract must explicitly regulate when and under what conditions the final deed will be executed.
Which documents should I request before signing?
At minimum: a title document or building right, a building permit, an encumbrance certificate, and a layout or plan of the specific unit. Where necessary, construction certificates and the developer's current corporate status should also be checked.
Is a lawyer's review of the contract worth it?
Yes, especially when the property value is high. A single omission in the clauses on deadline, penalty, payments or handover standard can cost far more than the price of a preliminary legal review.
