The encumbrance certificate: mortgage and lien checks

Real estate · Last reviewed: 2026-08-26

Two registers, two questions: the cadastre asks "what and where", the Property Register "whose and with what burdens"

Property information in Bulgaria lives in two separate systems, and mixing them up is the foreign buyer's most common trap. The CADASTRE (кадастър) holds the property's PHYSICS: identifier, boundaries, area, sketch — covered in our cadastre article. The PROPERTY REGISTER (имотен регистър) holds the property's LAW: the acts creating and transferring ownership, and the burdens on the property. The encumbrance certificate is the product of this SECOND system. The practical consequence: a flat with a spotless cadastral sketch can carry a mortgage and an injunction — the sketch does NOT show them. Your purchase file is not complete without documents from both systems.

The Property Register's logic is PUBLICITY: rights and burdens on property are kept in an open record so a buyer cannot end up saying "I didn't know" — and conversely, it becomes hard for a buyer to claim ignorance of a registered burden. The certificate is therefore not just an information sheet but the proof of your DUE DILIGENCE: whatever the seller tells you, what the register says prevails. A large share of property-fraud cases in Bulgaria run precisely through buyers who never asked for this document or settled for a stale-dated one — details in our property-fraud article.

What the certificate shows: reading the burden types

We have tabled the record types you may meet, with their meaning through a buyer's eyes. The general rule: EVERY record in the certificate must turn into an answered question before the notary stage — "will this burden be cleared, by whom, with what document?" A record without an answer means a contract left unsigned.

Certificate types: property-based or person-based?

The Registry Agency produces certificates along two axes. The PROPERTY-BASED certificate (удостоверение за имот) lists the records on a specific property — the standard tool of purchase due diligence. The PERSON-BASED certificate (удостоверение за лице) lists a specific person's register transactions — the tool of careful buyers and lawyers who want to see what is happening across the seller's other properties and whether widespread enforcement entries exist against them. In a serious purchase, reading both doubles the clarity: if the property looks clean while the seller's person record raises alarms, you will have asked your questions BEFORE the contract.

The certificate also has a TIME scope: for which period should records be traced? You specify the period in the application, and thrift here is false economy — request a period reaching far enough back to see the chain of transfers; your lawyer will say how many years make sense in the specific file. A short-period certificate is cheaper and faster but may miss an old lawsuit entry or a suspicious transfer in the chain.

How to request it: the application's content

The application's heart is describing to the register correctly WHAT you are asking. For a property-based certificate the application includes the data of the persons concerned and of their direct predecessors in title (those who transferred the property to them), the property's full description, its location and municipality, and AT LEAST THREE OF ITS BOUNDARIES — this content list is taken from the Registry Agency's official page (26 August 2026). In practice the data come from the seller's notarial deed and the cadastral sketch; with copies of both, the application is a matter of minutes. It is filed at the registry office (служба по вписванията) for the property's location; electronic filing has also opened — you may choose paper or electronic delivery.

The fee is set by tariff according to the service type and speed; we print no amounts — tariffs change, verify the current value on the official page on filing day. Know just this: the document's cost is a rounding error next to a transaction running into hundreds of thousands of euros; skipping the encumbrance certificate to "save costs" is like leaving the house uninsured to save the premium.

Where in the buying process: three checkpoints

1. 1

   Before an offer/deposit: first scan

   The moment a property gets serious, obtain the first certificate (or at least a current register check). Seeing a mortgage is no cause for panic — every credit-financed property has one; seeing an injunction or a lawsuit entry is cause to leave the table.
2. 2

   Preliminary-contract stage: tie the conditions to documents

   Have the preliminary contract (предварителен договор) record the burden inventory and clearance commitments: which mortgage, for what amount, deleted by what date; what happens to the deposit if deletion fails. "The seller said he'd handle it" is not a contract clause. The preliminary-contract mechanics are in a separate article.
3. 3

   Notary day: a FRESH certificate

   On transfer day make sure the register status is current — a new entry may have arrived in the intervening weeks. Notaries demand a current check anyway; your job is to CONFIRM it was done and to schedule your day so the signature lands on a fresh status.
4. 4

   After transfer: verify your own registration and the deletions

   Verify in the register that the sale deed was entered and that the promised burden deletions were recorded. Your file closes with the pre-purchase certificate + the post-transfer verification.

Against forgery: the 12-character verification code

The encumbrance certificate is valuable enough that a fraudster would want to fake it — and the system built the antidote: encumbrance certificates issued by the Property Register have carried a unique 12-character alphanumeric code since 19 March 2018, and you can verify online whether the document in your hands is identical to the one the Registry Agency issued (the verification page is in the sources; retrieved 26 August 2026). The rule is simple: trust not the document HANDED to you but the one verified by code or obtained yourself. Even if the seller's document is current and verified, an independent copy on your own application is cheap double-checking. When verifying, compare three things: that the code-retrieved document matches yours in content, that the property description matches the property you are negotiating, and that the issue date fits your transaction calendar. If any of the three fails, postpone signing day — registry matters forgive delay, not haste.

The foreign buyer's practical questions

Language: the certificate is drawn up in Bulgarian and its register language is technical. In a critical purchase, having it translated by a sworn translator or — better — interpreted by a real-estate lawyer is the most productive spend here: the lawyer does not merely translate but states the record's CONSEQUENCE. Power of attorney: if you are not in Bulgaria, your attorney-in-fact or lawyer can obtain the document; our power-of-attorney article explains the procedure. Buying through a company: if you buy via a Bulgarian company (common in land scenarios — see our land-ownership article), the burden check does not change; additionally, if the seller is a company, diligence on the Commercial Register side is also needed.

In new-build purchases the certificate's subject is often still the LAND PLOT and the developer's company: a mortgage on the plot — the construction loan — is normal, but the mechanism by which that mortgage is DELETED for your unit upon handover must be written in the contract. This scenario runs together with the Akt 14-15-16 stage checks; our Akt 16 and preliminary-contract articles are the other links of that chain.

Common mistakes

• •Never obtaining the certificate at all. "The agent checked, it's clean" is not a document. Buying without knowing of a registered burden means buying the burden too.
• •Settling for the seller's old document. The certificate is a snapshot; no signature goes on a stale snapshot. Obtain a fresh copy on your own application and verify the code.
• •Mistaking the cadastral sketch for a burden check. The sketch tells the physics, not the law. The two systems' documents do not substitute for each other.
• •Fleeing the table over a mortgage — or staying at the table over an injunction. A mortgage is a manageable standard; the injunction and the lawsuit entry are red flags not to be approached without a lawyer. Both lumping them together and failing to separate them are mistakes.
• •Closing the file while forgetting the post-sale stage. The file does not close without verified registration and deletions; the comfort of "the notary surely handled it" can shatter years later on a surprise entry.

Chain check: why the property's past matters as much as its present

When you extend the certificate's period backwards you are really reading a CHAIN: from whom to whom, by what act the property has passed. The chain's soundness is your assurance that today's seller can truly convey; a defect in one link (a voidable transfer, an unfinished inheritance partition, a missing spousal consent) can reopen your own deed to dispute years later. The chain scenario a foreign buyer meets most often is INHERITANCE: the property came from a deceased owner and the seller says "I am the heir". Here the certificate alone is not enough; the heirship certificates, the representation of ALL heirs in the sale and the closure of co-owners' rights are verified with a lawyer — our inheritance article maps this front. Another chain classic: a property that changed hands at short intervals. Not always a problem, but never skip the question "why was it sold so often?"; chains of rapid transfers are also used as a tactic to paper over a troubled past with fresh deeds.

Off-register debts: the complementary check set

We listed above what the certificate does not show; let us turn that list into tools. PROPERTY TAX and waste-fee debts live in municipal records — ask the seller for a current municipal "no liabilities" statement; our no-debt-certificate article explains the procedure. BUILDING-MANAGEMENT (etazhna sobstvenost) debts live in the manager's ledger — obtain a written debt statement from the manager; you do not want your first acquaintance with the neighbours to be an argument over "the old owner's debt" (see our fees-and-condominium article). ELECTRICITY, WATER and HEATING account debts live with the suppliers — request statements showing accounts settled to transfer day, together with meter readings. None of these three items is entered in the Property Register; requested alongside the certificate, they close the "debts" front of your purchase file from four sides.

A worked scenario: three surprises of a "clean" flat

Let us close with a fictional but familiar case. Picture a flat in Varna advertised as "a clean property awaiting its new owner". The first certificate shows a MORTGAGE: the seller's home loan. No panic — the bank confirms the balance and deletion terms in writing; the preliminary contract records that part of the price is paid straight to the bank and the mortgage deleted. The second surprise is in the person-based certificate: a lawsuit entry on another property of the seller. On enquiry it turns out to be a receivables claim from an old partnership — it does not touch your flat, but it explains the seller's haste; your lawyer insists the price be paid only at the notary's table, simultaneously with registration. The third surprise is not in the register: the building manager reports the old owner's accumulated fees; the debt is withheld from the sale price and settled on transfer day. Result: because all three surprises were found BEFORE signing, all three became negotiation items — the scenario where the same surprises emerge AFTER signing is called litigation, costs and years.

Who should look: the agent-notary-lawyer triangle

"Doesn't the agent/notary check all this anyway?" is a fair question, and the answer lies in the limits of the roles. The AGENT earns commission from the sale happening — a good agent gathers information but is not your side's counsel. The NOTARY guarantees the act's legality and looks at the current register status on transfer day — but the notary is both parties' notary and does not build your bargain; which condition clears the mortgage and how the deposit is protected is set by your contract, not the notary. The only figure defending YOUR interest alone is the real-estate LAWYER you retain. The practical formula for a foreign buyer: even in a small transaction, take hourly counsel for the document check and preliminary-contract review; full representation is the standard for big-budget or complicated files (inheritance, companies, lawsuit entries).

Is it useful when renting too?

The certificate is a buying tool, but it has a small role in long-term, high-deposit rentals too: seeing that the person claiming to be the landlord REALLY owns the property, and that it is not under enforcement, is cheap protection against fake-landlord fraud. For an ordinary tenancy, sight of the notarial deed usually suffices; but with a year's rent upfront, a high deposit or a commercial lease you will invest in, do not skip the register check — if the property you rented is sold at auction next month, "I didn't know" will not spare you the move. In short, low-deposit rentals the check's cost can exceed its benefit; there, put the weight on identity and deed checks.

Summary: the encumbrance certificate is the cheapest and strongest insurance of a Bulgarian property purchase — it shows the property's legal past and present burdens from the official record, and officially certifies their absence. Correct use rests on three principles: obtain early (once things get serious), tie to conditions (in the preliminary contract), keep fresh (at the notary). The operation described here was verified on 26 August 2026 against the Registry Agency's official pages; verify current fees and filing channels on the official page on the day you act. A final word: this document tells you WHAT exists, not WHAT TO DO — evaluating the records' legal consequence and turning it into negotiation is a decision you take with your real-estate lawyer. Read it with this batch's property chain: the cadastre check tells the property's physics, this article its law, the transfer article the transaction's flow, the preliminary-contract article the law of the bargain, and the fraud article the adversary's playbook — the five together are the complete textbook of safe buying in Bulgaria. You are making one of the largest outlays of your life; the care of a few documents is its only real insurance.
