BGB § 1626a — Elterliche Sorge nicht miteinander verheirateter Eltern (verbatim)¶

Jurisdiction: Germany · Citation: Bürgerliches Gesetzbuch § 1626a · Authoritative source: gesetze-im-internet.de — § 1626a BGB

The operative provision for parental responsibility allocation between unmarried parents in Germany. § 1626a establishes the three routes by which unmarried parents can share parental responsibility, and — critically following the 2013 reform — the presumption that joint custody serves the child's welfare in the absence of specific countervailing factors. The provision was substantially reformed following both the Zaunegger v Germany ECtHR judgment (2009) and the BVerfG 1 BvR 420/09 Federal Constitutional Court decision (2010), which together required Germany to provide unmarried fathers with an effective route to joint custody without dependency on maternal consent.

§ 1626a is doctrinally critical in PA litigation because it provides an unmarried father with statutory standing to acquire shared parental responsibility independently of maternal consent — closing the structural gap that previously enabled alienating mothers to block joint custody indefinitely.

Verbatim text (current consolidated, post-2013 reform)¶

§ 1626a BGB — Elterliche Sorge nicht miteinander verheirateter Eltern; Sorgeerklärungen¶

(1) Sind die Eltern bei der Geburt des Kindes nicht miteinander verheiratet, so steht ihnen die elterliche Sorge gemeinsam zu,

wenn sie erklären, dass sie die Sorge gemeinsam übernehmen wollen (Sorgeerklärungen),

wenn sie einander heiraten oder

soweit ihnen das Familiengericht die elterliche Sorge gemeinsam überträgt.

(2) Das Familiengericht überträgt gemäß Absatz 1 Nummer 3 auf Antrag eines Elternteils die elterliche Sorge oder einen Teil der elterlichen Sorge beiden Eltern gemeinsam, wenn die Übertragung dem Kindeswohl nicht widerspricht. Trägt der andere Elternteil keine Gründe vor, die der Übertragung der gemeinsamen elterlichen Sorge entgegenstehen können, und sind solche Gründe auch sonst nicht ersichtlich, wird vermutet, dass die gemeinsame elterliche Sorge dem Kindeswohl nicht widerspricht.

(3) Im Übrigen hat die Mutter die elterliche Sorge.

English working translation¶

§ 1626a BGB — Parental responsibility of parents not married to one another; declarations of parental responsibility¶

(1) Where parents are not married to one another at the time of the child's birth, parental responsibility is held jointly,

where they declare that they wish to assume responsibility jointly (Sorgeerklärungen),

where they marry one another, or

in so far as the family court transfers parental responsibility to them jointly.

(2) Pursuant to paragraph 1 number 3, on the application of one parent, the family court shall transfer parental responsibility, or part of parental responsibility, to both parents jointly where the transfer does not contradict the welfare of the child. Where the other parent advances no grounds capable of standing in the way of the transfer of joint parental responsibility, and such grounds are not otherwise apparent, it is presumed that joint parental responsibility does not contradict the welfare of the child.

(3) Otherwise, the mother has parental responsibility.

Why this matters for PA¶

Three routes for unmarried fathers to acquire joint PR. Subsection (1) creates three structural routes:
(1)(1) — Sorgeerklärungen: the parents jointly declare their intention to share custody. Requires both parents' active engagement.
(1)(2) — Marriage: subsequent marriage automatically confers joint custody.
(1)(3) — Court order: family court transfers joint custody on application of one parent.
Subsection (1)(3) is the PA-critical route. Where the mother refuses to engage with Sorgeerklärungen — including as part of an alienating-conduct pattern — the unmarried father can apply directly to the Familiengericht under subsection (1)(3). This is the structural gap that the 2013 reform closed: prior to Zaunegger v Germany and BVerfG 1 BvR 420/09, unmarried fathers had no court route to joint custody without maternal consent.
Subsection (2) — the presumption. Trägt der andere Elternteil keine Gründe vor, die der Übertragung der gemeinsamen elterlichen Sorge entgegenstehen können, und sind solche Gründe auch sonst nicht ersichtlich, wird vermutet, dass die gemeinsame elterliche Sorge dem Kindeswohl nicht widerspricht. This is the operative pro-joint-custody presumption: in the absence of specific countervailing grounds, joint custody is presumed to serve the welfare interest. The burden is on the parent opposing joint custody to advance the grounds.
Doctrinal significance for PA cases. The 2013 reform was a direct legislative response to the structural injustice of unmarried fathers being indefinitely excluded from joint custody by alienating maternal conduct. The presumption framework means a court must transfer joint custody on application unless the opposing parent establishes specific welfare-incompatibility grounds.
Subsection (3) — the fallback. Im Übrigen hat die Mutter die elterliche Sorge. Where none of subsection (1)'s three routes operates, the mother has sole parental responsibility. This is the structural default that the 2013 reform left in place; the subsection (1)(3) court-order route is the operative response to that default in cases of paternal application.

Procedural application¶

Sorgeerklärungen are made before the Jugendamt (youth welfare authority) or a Notar (notary) — formal declaration procedure
The court application under subsection (1)(3) is made to the Familiengericht on Form FamFG-equivalent
Welfare assessment by the Jugendamt and (where appropriate) court-appointed Sachverständigengutachten — see expert evidence comparative
The Verfahrensbeistand under § 158 FamFG represents the child's interests
The presumption under subsection (2) shifts the burden: the opposing parent must substantively engage with the welfare assessment to advance grounds

Use in alienating-conduct cases¶

The leading authority on subsection (1)(3) applications in alienating-conduct contexts is the BGH XII ZB line plus the lower-court jurisprudence developing under the 2013 reform
Where an alienating mother opposes the application without substantive welfare grounds, subsection (2) presumption operates — joint custody must be transferred
Where the alienating conduct extends to sustained pre-application behavioural patterns (disparagement, contact-frustration, false allegations), the court can engage BGB § 1666 Kindeswohlgefährdung measures alongside the § 1626a custody decision
The structural significance: § 1626a (1)(3) gives unmarried fathers the same operational standing in PA litigation that married fathers have under § 1671 BGB — closing a doctrinal gap that previously favoured alienating mothers

Leading authorities — ECtHR + BVerfG¶

Zaunegger v Germany (ECtHR, 3 December 2009) — held that the pre-reform regime breached Article 14 + Article 8 ECHR by discriminating against unmarried fathers
BVerfG 1 BvR 420/09 (Federal Constitutional Court, 21 July 2010) — declared the pre-reform regime unconstitutional under Article 6 GG
The 2013 reform implementing both judgments converted the § 1626a regime to its current presumption-based structure
