A registered deed and physical occupation answer different questions. ARG helps establish the acquisition behind each claim and choose a remedy that can secure title, possession or removal of an obstruction.

Can another person own the same Bulgarian house when you already hold a notarial deed? Clients ask ARG this after a neighbour produces a second deed or a relative claims that years of living in the property made it exclusively theirs. The dates, source of each title and nature of the occupation determine the response.
ARG arranges advice and representation through authorised Bulgarian lawyers for situations such as these.
A claimant must support the particular legal basis of its right, not simply identify weaknesses in an opponent’s paperwork.
Recovering possession, establishing ownership and removing interference are different remedies with distinct conditions.
Historical plans and expert measurements must connect the claimed right to a precisely described property or physical part.
The requested judgment should support enforceable relief and any necessary subsequent register or cadastral action.
The substantive starting point is the Ownership Act (Закон за собствеността, ЗС), particularly Articles 77, 108 and 109. Its distinction between ownership and remedies protecting it is broadly comparable in function to property and possession remedies in England and Wales, although Bulgarian acquisition rules and procedural requirements must be applied independently. Ownership may arise through a transaction, acquisitive prescription or another legally recognised method. Possession describes a factual relationship with the property. A person can own a house while another person controls it, and a person can occupy a house without owning it.
A disputed title is established through the acquisition facts, not by counting deeds. The Civil Procedure Code (Граждански процесуален кодекс, ГПК) allocates the burden of proving the relevant facts under Article 154, paragraph 1. Its function is comparable to allocation of proof in civil litigation in England and Wales, although the Bulgarian procedural rules govern. A claimant relying on a purchase must establish the acquisition claimed; an opposing party relying on prescription must substantiate the possession necessary for that independent basis. The legal significance of a notarial deed must be assessed within that evidential structure.
A notarial deed is significant evidence, but its legal significance depends on what it records. A deed documenting a sale establishes a transaction that must be examined together with the seller's title. A declaratory deed recognises an ownership claim through a noncontentious procedure. Neither allows the court to avoid deciding a properly raised dispute over the underlying acquisition. The central question is not whether a document exists, but whether the facts required for the asserted method of acquisition occurred and whether the right later passed to someone else or was lost.
The authoritative distinction appears in Interpretative Decision No. 11/2012 of 21 March 2013, interpretative case No. 11/2012, of the General Assembly of the Civil Chamber of the Supreme Court of Cassation. A declaratory deed has a legitimising effect, but the notary's conclusion about ownership is not conclusive certification of a fact under Article 179, paragraph 1 ГПК. The decision also explains that, where both parties rely on notarial deeds, each must prove the acquisition on which their own right rests under the general allocation in Article 154, paragraph 1 ГПК. The practical response is a substantive case about title, not a bare assertion that the opponent's document is worthless.
A chain of acquisition explains how the present claimant obtained the right from a person entitled to transfer it. Each link must concern the same property and the same extent of ownership. If a seller owned one half, a later deed purporting to sell the whole cannot ordinarily transfer the other half merely because the notary recorded that description. The investigation therefore follows the legal source of the seller’s right, not only the newest entry or the number of documents collected.
Succession, partition and separate ownership of a building can change that chain. A certificate identifying heirs helps identify successors, but it does not itself show that the deceased owned the disputed asset. A division may explain why one heir later transferred a particular apartment rather than an undivided share. For each disputed link, the question is what legal event created or passed the right and what evidence proves that event. An independent acquisition through prescription may alter the analysis even where an earlier transfer was defective.
Long occupation requires an equally careful distinction. Possession combines factual control with holding the property as one's own, while holding for somebody else is a different relationship under Article 68 ЗС. A tenant, caretaker or family member admitted with permission does not necessarily begin acquiring ownership merely by remaining in the building. The presumption in Article 69 ЗС assists with the intention element, but evidence that occupation began on behalf of another person may rebut it. Letters acknowledging the owner's title, requests for permission to renovate and payments identified as rent can therefore be more important than the occupant's present description of their intentions.
Use can have a lawful contractual or proprietary basis without conferring ownership. A tenant may be entitled to remain while the lease binds the owner; a holder allowed to look after the house acknowledges someone else’s right. The owner’s recovery demand therefore needs to address the legal basis for occupation and whether it has ended. Conversely, paying utilities or maintaining the roof does not by itself transform a permitted user into an owner. Those payments may prove occupation or expenditure, while leaving the essential acquisition question unanswered.
The ordinary period for acquisition of immovable property is ten years of uninterrupted possession under Article 79, paragraph 1 ЗС. The five-year period in paragraph 2 requires good-faith possession within the legal meaning of Article 70, including a suitable legal basis and the relevant lack of knowledge at its inception. Honest personal belief is not a substitute for those requirements. Nor should the specific protection given to a buyer in possession under a preliminary contract with the owner be confused with automatic access to the shorter acquisition period. The transaction, the nature of possession and the applicable period must be considered separately.
The chronology must identify the beginning of possession, its extent and any relevant interruption. Loss of possession for more than six months interrupts prescription under Article 81 ЗС. Joining a predecessor's possession is possible under Article 82, but requires a genuine connection to that predecessor's possession rather than adding unrelated periods of use by different people. The presumption of continuity in Article 83 helps a person who proves possession at different times, subject to contrary evidence. A witness who remembers a garden being cultivated in two summers may support part of the chronology, yet cannot automatically establish exclusive possession of the whole parcel throughout a decade.
Registration addresses the publicity and opposability of rights, but it does not ordinarily cure acquisition from a non-owner. The priority rule in Article 113 of ЗС concerns competing rights acquired from the same transferor. It should not be reduced to a rule that whichever deed was registered first defeats every other possible ownership claim. Where the competing titles come from different alleged owners, the substantive acquisition history must still be proved. A current certificate is therefore an important part of the investigation, not a substitute for it.
An allegation that a signature was forged raises a different issue from an allegation that an authentic deed recognises a person who never acquired ownership. Authenticity challenges follow Article 193 ГПК and must be made within its procedural timing rules. An ownership challenge examines the facts and legal effect of the acquisition itself. For example, genuine witness statements before a notary may still describe permissive occupation rather than possession as owner. Treating that problem as forgery can distract the case from the fact that actually defeats the asserted title. The evidence request and the legal objection should correspond to the alleged defect.
If the owner remains in control and another person merely asserts a competing title, a declaratory claim may be appropriate. ГПК permits proceedings to establish a right where a legal interest exists under Article 124, paragraph 1. The broad procedural function is comparable to declaratory relief and civil case management in England and Wales, but the Bulgarian requirement for a concrete legal interest governs the case. A conflicting deed or a serious assertion obstructing the owner's dealings can be relevant. Abstract curiosity about a historical document does not justify asking a court to resolve an otherwise hypothetical dispute.
Where the client has lost control, the recovery claim under Article 108 ЗС requires more than a declaration that the defendant's deed is defective. The claimant must establish ownership of the identified property and the defendant's possession or holding, while the defendant may rely on a lawful basis that is enforceable against the owner. A sale by someone who never owned the disputed rooms does not necessarily transfer those rooms merely because the transaction was notarised. Conversely, the claimant's ownership alone does not defeat an existing right permitting the defendant to occupy them. The content, duration and enforceability of that right require separate examination.
This distinction has a direct effect on the judgment. In Interpretative Decision No. 4/2014 of 14 March 2016, interpretative case No. 4/2014, the General Assembly of the Civil Chamber of the Supreme Court of Cassation held that a court deciding an Article 108 claim must pronounce separately on the claimant's ownership. Its reasoning explains that ownership may be recognised even when delivery is refused because the defendant does not possess the property or has a basis for possession enforceable against the owner. A client's objective therefore needs to be expressed accurately. Recognition of title and obtaining the keys are related, but legally distinct, outcomes.
Co-ownership adds a further complication. Interpretative Decision No. 1/2012 of 6 August 2012, interpretative case No. 1/2012, of the General Assembly of the Civil Chamber of the Supreme Court of Cassation directs attention to how factual control began. When a co-owner initially holds the other shares as part of a shared arrangement, a later claim to exclusive ownership requires evidence of a manifested change. Merely paying expenses or remaining in the inherited home cannot be mechanically equated with excluding the other owners' rights. An unequivocal refusal of their rights and the circumstances in which that refusal became known are potentially decisive facts.
The legal response depends on whether the claimant denies co-ownership altogether or merely excludes another co-owner from use. A claim to the other shares through prescription requires proof directed at those shares and the necessary period. If ownership shares are accepted but access is refused, the dispute may concern use or compensation rather than who owns the whole building. The pleading should make that distinction clear. It should also identify whether the contested deed recognises exclusive ownership or records a transfer of a share the seller actually held.

Start with the acquisition that the client will actually rely on. The Ownership Act (Закон за собствеността, ЗС) recognises the principal acquisition routes in Article 77 and defines possession and holding in Article 68. The distinction has a broad functional parallel with ownership and possession remedies in England and Wales, but Bulgarian law supplies the conditions for the Bulgarian property. If the claim rests on a purchase, the evidence must connect the seller's entitlement, the conveyance and the asset. If it rests on prescription, the evidence must establish control as owner over the required period. The two investigations overlap without being interchangeable.
Property identity deserves equal attention. A street number, a cadastral identifier and an old plot number may all describe the same place, but that conclusion must be supported. If the dispute concerns only a strip along a boundary, claiming an entire neighbouring parcel may be both inaccurate and unnecessarily expensive. Historical plans, acquisition documents and technical comparison help determine which physical area is covered by each alleged title. The court, rather than the surveyor, decides ownership. The surveyor's role is to explain the geographical and technical facts on which that legal decision depends.
A useful document file includes the complete deeds and their attachments, rather than cropped photographs of the page naming the owner. Earlier deeds, plans and records of changes to identifiers can reveal whether the described property remained the same. An old deed may refer to a parcel later divided into several objects. A later document may concern only an undivided share. The file should record those changes and identify the disputed area consistently. Where a party claims a building but not the land, or land subject to separately owned construction, Article 63 ЗС makes it particularly important to avoid treating the whole site as one undifferentiated asset.
Successor documents must connect the person named in the old deed to the party asserting rights now. Death records, heir certificates, wills, partitions and later transfers may explain different parts of that connection. An heir certificate does not determine every contested testamentary or ownership question. Where a company has changed name or undergone succession, the relevant registry history is needed to establish the same legal identity or the actual transfer of rights. A similar name on two documents is not sufficient proof that their holders are the same person.
Possession evidence should be organised around events. Who delivered the keys, in what capacity and with what understanding? Who could exclude others? Did the owner continue to store belongings, collect rent or authorise work? When did the occupant first deny another person's rights? These questions help distinguish possession as owner from holding under permission. The beginning, continuity, any interruption and any reliance on a predecessor's possession all affect the result under Articles 79, 81, 82 and 83 ЗС. A witness should describe what they personally observed and when, rather than offer a legal conclusion that a person had always been the owner.
Preserve communications in a form that retains context. A message agreeing that a relative may live in the house can be significant even if another message later calls it that relative's home. The sequence may explain whether an arrangement remained permissive or changed into a disputed assertion of ownership. Photographs should retain their original files where possible, together with information identifying the site and date. Selective screenshots or undated images may still be relevant, but they leave more room for challenge. The purpose is to preserve reliable evidence, not to assemble only material that appears favourable before its full meaning is understood.
The evidential burden is governed by Article 154, paragraph 1 of the Civil Procedure Code (Граждански процесуален кодекс, ГПК). This performs a broadly comparable procedural function to proof and case management rules in England and Wales, but the Bulgarian allocation and deadlines control. Each proposed document or witness should answer a particular factual proposition. A utility bill may connect a person to use of a house at a date. It does not necessarily prove ownership, exclusive possession or the boundaries of the occupied land. An archive deed may prove a transaction while leaving the transferor's acquisition in dispute. Recognising these limits prevents a large file from creating false confidence.
Where competing deeds exist, obtain the material underlying any declaratory notarial procedure if legally available through the relevant route. Interpretative Decision No. 11/2012 of 21 March 2013, interpretative case No. 11/2012, of the General Assembly of the Civil Chamber of the Supreme Court of Cassation explains both the deed's legitimising effect and its susceptibility to an ownership challenge. The inquiry should therefore ask what possession or documents supported the notary's conclusion. The later lawsuit is not an appeal from the notary's opinion. It is a contentious determination of the right, supported by evidence that may confirm or displace the asserted acquisition.
Protection pending judgment should address an identified risk. Interim security under Article 391 ГПК requires a danger to effective realisation of the eventual judgment and the prescribed evidential or guarantee conditions. A request should explain the threatened dealing or change and why the proposed measure fits it. The court may require a guarantee even where documents support the claim. Such protection does not establish ownership, and it should not be requested merely to exert pressure unrelated to the litigation. Evidence preservation under Article 207 serves a different purpose and may be necessary alongside, or instead of, an interim measure affecting the property.
Physical conditions can require early technical work. A survey can identify the area enclosed by a fence and compare it with historical descriptions. An engineer may distinguish a building's original structure from later works relevant to an improvement claim. If demolition or alteration threatens evidence, Article 207 ГПК allows preliminary collection where evidence may be lost or become difficult to obtain. The application should identify the threatened evidence and the issue it will prove. It should not ask the expert to decide ownership, because that legal conclusion belongs to the court after the parties' competing positions have been heard.
Registration must be handled according to the actual claim. The relevant ownership claims fall within Article 114 ЗС, whereas Interpretative Decision No. 4/2015 of 6 November 2017, interpretative case No. 4/2015, of the General Assembly of the Civil Chamber of the Supreme Court of Cassation states that Article 109 claims are not registrable. Registration is also distinct from a prohibition or attachment granted as interim security. The client should understand the effect sought against later rights and the limits of that effect. A registered claim is not a judicial declaration that the claimant has already won, nor does it resolve every risk arising from continued occupation.
Registration work continues after the merits are decided. Final judgments on the relevant registered claims are annotated, and the provision addresses the six-month period for annotation and the loss of the claim registration's effect if it expires under Article 115 ЗС. The practical file should therefore include a reliable record of finality and the steps required to present the judgment for the appropriate entry. Winning the case while leaving the registration consequence unattended can create avoidable difficulties with later dealings. A future buyer or lender will need a coherent documentary record that connects the original claim to the final judicial result.
The court must be selected by the applicable procedural rules rather than convenience. Claims concerning real rights in immovable property, boundaries and disturbed possession generally follow the property's location under Article 109 ГПК. The competent level of court must also be identified from the nature and value of the claim. A party's residence abroad does not make a Bulgarian property's ownership dispute an ordinary debt claim that can be brought wherever correspondence is easiest. Any international element requires its own jurisdiction and service analysis, but it does not remove the need to identify the property and the precise relief requested.
The defendant should treat service as the beginning of a procedural timetable, not as an invitation to wait for the first hearing. The ordinary written response period under Article 131, paragraph 1 ГПК is one month. Defences and supporting evidence need to be raised in accordance with the applicable rules, including the consequences of omission under Article 133. A defendant relying on prescription should identify the possession period and supporting facts. A defendant relying on permission or another enforceable occupancy right should produce that basis. A claim for improvements or a retention defence requires its own timely factual explanation rather than a general statement that substantial money was invested.
A foreign document used in Bulgarian proceedings normally needs an accurate Bulgarian translation under Article 185 of ГПК. Foreign succession or civil-status records must also be assessed for the legal effect they establish and the applicable authentication requirements. Translating a foreign inheritance document does not alone prove that Bulgarian land belonged to the deceased. Counsel should identify whether it proves identity, succession or an underlying acquisition, and whether a separate applicable recognition mechanism is needed. A representative’s authority must cover the intended procedural steps.
If voluntary delivery does not occur, an enforceable order for possession is implemented through the lawful enforcement process. The enforcement officer fixes the date and time for putting the entitled person into possession, notifies the parties and records the act on site under Article 522, paragraph 1 ГПК. A debtor who does not leave voluntarily can be removed through that process. The successful claimant should provide the property identification and relevant practical information, but should not attempt to replace the officer's powers with private force. A disputed boundary or unclear description can make enforcement harder, which is why precision in the original claim matters so much.
Third-party occupation creates additional questions. The timing at which a third person obtained possession and any asserted rights excluding those of the enforcement creditor affect the procedure under Article 523 ГПК. The provision allows a short opportunity to seek suspension in the stated circumstances. The existence of the judgment does not justify assuming that every person present can be ignored. Equally, moving another person into the premises after litigation began does not necessarily defeat enforcement. The officer must apply the statutory process, and the parties should preserve evidence about when possession changed and on what basis the third person claims to be there.
