Preliminary sale contract for Bulgarian property
Ownership of Bulgarian real estate passes only through a notarial deed. The preliminary contract signed beforehand binds the parties to complete the sale but does not make the buyer an owner. The practical consequence is blunt: a buyer who has paid a deposit holds a claim, and the worth of that claim depends entirely on how the contract was drafted.

What the preliminary contract is for
It usually buys time: the buyer is finishing a mortgage file, the seller is collecting missing documents, or a new building is waiting for its permit to use. In the meantime the price, the handover terms and the date of the notarial deed are fixed in writing. Written form is the essential requirement here; verbal agreement and message threads do not substitute for it.
What the contract must settle
- A description of the property by cadastral data: unit identifier, area, share of common parts, storage room and parking space.
- The price, the payment schedule and which stage each instalment is tied to.
- The date of the notarial deed, or the event that determines it, such as issuance of the permit to use.
- The consequences of non-performance: withdrawal, refund, penalty and delay.
- The seller's declaration on mortgages, attachments, tenancies and other encumbrances.
If a party backs out
Because the preliminary contract does not transfer ownership, a seller who fails to appear at the notary leaves the buyer with a court route: Bulgarian law allows a preliminary contract to be declared final by judgment. The route exists, but it costs time and money, so the real protection is a well-drafted contract and checking encumbrances before signing.
The order of pre-signature checks
Trace the ownership
Check who the property is registered to and what entries stand against it through the services of the Registry Agency.Match the cadastral identifier
Compare the listing with the cadastre agency records: is it the same unit, do the area and the floor agree.Fix the payment mechanics in writing
Which account, at which stage and against which document each payment is made belongs in the contract. Cash payments are hard to prove in a dispute.Verify any power of attorney
If an attorney signs for the seller, have the scope and validity of the power checked by a notary; the power to dispose must be express.

Frequently asked questions
Must the preliminary contract be notarised?
Written form is the essential requirement. Notarial certification is not always mandatory, but it puts the signatures and the date beyond argument, which helps in deals with a developer.
Can I get the deposit back?
The answer sits in the contract: whatever it says about refund, penalty or set-off is what applies. That is precisely why those clauses are read before signing.
Can a foreigner sign a preliminary contract?
Yes, contracting does not depend on citizenship. For some categories of property the acquisition rules differ, so clarify what right you are actually acquiring before you sign.
