Written and reviewed by Adriana Melnikliyska, Attorney-at-law, Blagoevgrad Bar No. 1900000227. Last reviewed 27 September 2026.Who this page is for
This page is written for a parent — or, less often, a grandparent or other relative with a recognised interest — facing a parental-responsibility question with a genuine connection to Bulgaria: a Bulgarian citizen and a foreign citizen separating with a child involved; two foreign nationals whose child was born in Bulgaria or is habitually resident there; a parent living abroad who needs a Bulgarian court's decision recognised or enforced elsewhere, or a foreign decision recognised in Bulgaria; or a parent concerned that the other parent may remove, or has already removed, a child across an international border without proper agreement or authority.
It is not written for a purely domestic Bulgarian family with no international element, and it is not a substitute for reviewing the actual family situation. Custody questions are intensely fact-specific: the child's age, where the child has actually been living and going to school, the existing relationship with each parent, any prior court or agency involvement, and what each parent is realistically able to offer all shape the analysis. Nothing on this page should be read as a prediction of how any specific case will be decided.
Bulgarian custody law under the Family Code
Bulgarian domestic law does not use the word "custody" as a single legal category. Instead, the Family Code separates parental authority into several distinct components that a court (or the parents, by agreement) can allocate: the exercise of parental rights and obligations (day-to-day decision-making and the child's principal residence), the child's actual place of residence, a personal-relations regime for the parent who does not exercise the rights day-to-day (commonly called a contact or visitation schedule), and maintenance (child support). These can be, and often are, allocated differently from how a foreign client instinctively expects — for example, "joint custody" in the sense used in some other legal systems does not map exactly onto a single Bulgarian legal concept, and what is actually agreed or ordered needs to be described precisely in Bulgarian legal terms to be enforceable.
The Supreme Court of Cassation has directly addressed how far "joint custody" can go under Bulgarian law. In Interpretive Decision No. 1/2016 of 3 July 2016 (ОСГК на ВКС), the court held that Family Code Article 59(2) rules out joint exercise of parental rights only where the parents have not reached agreement on it — meaning a court cannot impose a shared-exercise arrangement on parents who disagree, but may approve one where the parents themselves have agreed to it and it serves the child's interests. In a contested case where the parents cannot agree, the court must still assign the exercise of parental rights to one parent.
Where parents cannot agree, a Bulgarian court decides these questions applying the Family Code's central and overriding standard: the best interests of the child. This is not a slogan — it is the operative legal test that displaces what either parent would prefer, and Bulgarian courts are required to examine the actual facts of the child's life, not general assumptions about either parent's fitness. Where parents can agree, the Family Code still requires the court (in a mutual-consent divorce) or another competent authority to review and approve the arrangement, precisely because the child's interests are treated as something the state has a role in protecting, not purely a private matter between the parents.
How a Bulgarian court decides what is in a child's best interests
Bulgarian courts assess a broad, fact-specific set of circumstances rather than applying a fixed formula, and no two cases are decided on an identical basis. Factors that Bulgarian courts and practice commonly examine include: the child's age and, where the child is old enough to form and express a reasoned view, the child's own opinion (heard directly or through a suitable professional, in a manner appropriate to the child's age and maturity); each parent's capacity to raise the child, including their living situation, working arrangements, and support network; the existing emotional bond between the child and each parent; the stability of the child's current environment, including school, friends and community; each parent's willingness to support the child's relationship with the other parent; and, where relevant, any evidence of violence, neglect, substance misuse, or other conduct bearing on a parent's fitness. A social investigation report, typically prepared by the relevant child-protection department, is a standard feature of contested Bulgarian custody proceedings and often carries significant weight with the court.
None of these factors operates as an automatic rule in either direction. A parent's nationality, a parent living abroad, or a parent's gender is not, by itself, decisive of anything under Bulgarian law — despite a persistent misconception among some foreign clients that Bulgarian courts favour a Bulgarian parent, or that either parent is automatically favoured. What actually drives the outcome is the specific evidence about the specific child's life and each parent's actual role in it.
Custody within a divorce, and custody as a standalone matter
Where parents are married and divorcing, parental-responsibility questions are usually decided within the same proceeding as the divorce itself — either through a settlement agreement the parents reach and the court reviews and approves (in a mutual-consent divorce), or through the court's own decision as part of a contested divorce judgment. Where parents were never married, or where circumstances change after a divorce or an earlier order, a parent can bring a standalone claim asking the court to determine or modify the exercise of parental rights, residence, contact and maintenance. Either route applies the same best-interests standard; the difference is procedural, not substantive.
Cross-border cases: jurisdiction and applicable law
For a family connected to more than one EU member state, Regulation (EU) 2019/1111 — which recasts and replaces the earlier Regulation (EC) 2201/2003 for proceedings started on or after 1 August 2022 — governs which member state's courts have jurisdiction over parental-responsibility matters, and how a decision made in one member state is recognised and enforced in another. The primary connecting factor under this Regulation is the child's habitual residence at the time proceedings are started, not either parent's nationality and not where the parents were married. This matters in practice: a Bulgarian court does not automatically have jurisdiction over a child simply because one parent is Bulgarian, and a foreign court does not automatically lose jurisdiction simply because a parent later moves to Bulgaria — the child's actual, habitual living situation at the relevant time is what the Regulation looks to.
Where the other country involved is outside the EU, jurisdiction and applicable law are instead worked out through Bulgaria's Private International Law Code, applied alongside the 1996 Hague Convention on Jurisdiction, Applicable Law, Recognition, Enforcement and Co-operation in Respect of Parental Responsibility and Measures for the Protection of Children where the other state is also a party to it, and alongside whatever jurisdictional rules that other country's own courts would apply on their side. Establishing which framework actually governs a given cross-border custody question — EU Regulation, the 1996 Hague Convention, or ordinary Bulgarian private-international-law rules — is one of the first and most consequential steps in any international custody matter, and it needs to be checked against the child's actual, current habitual residence and the countries genuinely involved, not assumed from where the parents happen to hold citizenship.
International child abduction: the 1980 Hague Convention
Where one parent removes a child to another country, or refuses to return a child from what was meant to be a temporary stay abroad, without the other parent's consent or a court's authorisation, this can amount to wrongful removal or wrongful retention under the 1980 Hague Convention on the Civil Aspects of International Child Abduction, to which Bulgaria is a party. The Convention's central purpose is narrow and specific: it is not designed to decide who should ultimately have custody. Instead, it provides a mechanism, operated through designated Central Authorities in each contracting state (in Bulgaria, this function sits with the Ministry of Justice), aimed at securing the child's prompt return to their country of habitual residence, so that the custody question itself can then be decided by the courts of that country — on the reasoning that removing a child unilaterally should not itself be allowed to determine which court ends up deciding custody.
A Hague return application is a separate legal process from a custody claim, with its own limited set of defences recognised under the Convention (for example, that the child is now settled in the new country after a significant period, that there is a grave risk of harm in returning, or that the child, being of sufficient age and maturity, objects to the return). Where both the country of origin and the country the child was taken to are EU member states, Regulation (EU) 2019/1111 supplements and, in some respects, modifies how the 1980 Convention operates between them, including rules aimed at ensuring return proceedings are dealt with without delay. Because both the Convention and the Regulation attach real legal consequences to timing, and because the available defences are narrow and fact-specific, a suspected or actual cross-border removal is a matter to have reviewed urgently rather than addressed informally between the parents, without this page stating a specific number of days that applies to every case — that needs to be checked against the current text and the actual facts.
Documents and evidence that typically matter
What a Bulgarian court, or a Hague Central Authority, actually needs to see depends on the specific question being decided, but the following categories recur across most custody and cross-border matters:
- The child's birth certificate and, where relevant, proof of each parent's legal relationship to the child.
- Evidence of the child's habitual residence — school enrolment, medical registration, tenancy or property records, and similar day-to-day proof of where the child has actually been living.
- Any existing agreement or court order touching on custody, residence, contact or maintenance, from Bulgaria or any other country.
- Evidence relevant to each parent's situation — housing, income, working hours, support network, and, where genuinely relevant, any documented concerns about a parent's conduct.
- Communications between the parents bearing on consent (or its absence) to travel, relocation, or a change in the child's living arrangements.
- Certified translations of any foreign-language documents, since Bulgarian proceedings require the Bulgarian text.
Assembling a clear, chronological, well-documented record is consistently one of the more decisive factors in how quickly and how well a custody or cross-border matter can actually be assessed and presented.
Modifying an existing custody arrangement
An existing Bulgarian custody decision or approved settlement agreement is not necessarily permanent. Bulgarian law allows a parent to seek a modification where circumstances have materially changed since the original decision — a parent's relocation, a significant change in the child's needs or preferences as they grow older, a change in either parent's circumstances, or evidence that the current arrangement is no longer serving the child's best interests. A modification claim is not an opportunity to relitigate the original decision on the same facts; it requires showing a genuine, material change, assessed again under the same best-interests standard.
Cross-border recognition and enforcement of a custody decision
Within the EU, Regulation (EU) 2019/1111 generally allows a parental-responsibility decision made in one member state to be recognised and enforced in another without a separate declaration of enforceability for most decisions, subject to specific, limited grounds on which recognition can be refused (for example, a serious breach of the child's right to be heard, or an irreconcilable later decision). Outside the EU, recognition and enforcement depend on Bulgaria's Private International Law Code and, where applicable, the 1996 Hague Convention, or on whatever bilateral or other arrangement exists with the specific country involved. In every cross-border case, whether a decision obtained in one country will actually be given effect in another is a distinct legal question from whether that decision was correctly obtained in the first place, and both need to be checked.
Common mistakes and misconceptions in cross-border custody matters
- Assuming a Bulgarian court automatically has jurisdiction because a parent is Bulgarian. Jurisdiction generally follows the child's habitual residence, not either parent's nationality.
- Relocating with the child, or agreeing informally to a temporary stay abroad, without written consent or a clear understanding of what "temporary" means. This is one of the most common paths into a wrongful-removal or wrongful-retention dispute, often unintentionally.
- Assuming "joint custody" in the sense used in another country translates directly into an identical Bulgarian legal arrangement. The underlying components (exercise of rights, residence, contact, maintenance) need to be defined precisely in Bulgarian legal terms.
- Believing a parent's gender or nationality decides the outcome. Neither is, by itself, decisive under the best-interests standard actually applied.
- Waiting to act after a suspected wrongful removal. The Hague return mechanism and its defences are time- and fact-sensitive; delay can narrow the realistic options.
- Treating an informal parenting agreement as legally binding or enforceable without court approval. An agreement that has not been reviewed and approved by a competent authority generally carries far less protection if the other parent later departs from it.
Realistic framing: what this process can and cannot promise
No custody matter can be promised a particular result, and it would be professionally improper to suggest otherwise. What can be said honestly is this: a Bulgarian court's decision follows from the child's best interests as assessed on the actual evidence, not from either parent's preference, and both parents are entitled to have their situation and their relationship with the child properly presented and considered. A well-documented, well-presented case does not guarantee a particular outcome, but it does give the court the material it needs to reach a properly reasoned decision, and it avoids some of the most common, avoidable setbacks — missing documentation, an unclear jurisdictional basis, or a poorly evidenced position. Part of the value of a proper legal review is an honest early assessment of the jurisdictional and evidentiary position, not a prediction of the result.
Handling this from abroad
Many clients raising a Bulgarian custody question are not living in Bulgaria. An initial review can generally begin with a written account of the family situation, the relevant documents, and a description of what has already happened or been agreed, sent by email, followed by a call to confirm the jurisdictional position and realistic next steps. Where a formal step requires a signature and personal attendance is not practical, a power of attorney — apostilled or legalised as required by the country you are in — can be used for many procedural steps, in the same way it is used across other matters on this site; see power of attorney for how that document is prepared. Some steps in a contested custody matter, particularly a hearing where the child's own views are taken, may still require attendance depending on the facts — this is identified early rather than assumed either way.
Fees and how a custody matter is scoped
The fee for a custody or parental-responsibility matter depends entirely on what is actually involved: an uncontested arrangement reviewed as part of a mutual-consent divorce is a very different scope of work from a contested cross-border custody dispute, a modification claim, or a Hague return application. We do not quote a fee before reviewing the facts, and we do not promise a particular outcome, timeline, or arrangement — every custody matter depends on the child's actual situation and the evidence available. The scope and the professional fee are set out in writing before any substantive work begins.
