GermanyCan unmarried fathers get custody rights?
Yes, unmarried fathers in Germany can obtain custody rights—but only after legally establishing paternity and, typically, obtaining court-ordered joint or sole custody.
What the Law Says
In Germany, parental custody (elterliche Sorge) is not automatic for unmarried fathers—even if biological. The law distinguishes sharply between married and unmarried parents, and custody rights depend on formal legal status—not biology alone.
Under BGB § 1626, both parents have joint custody rights *only if* they are married at the time of the child’s birth—or if they later declare joint custody (with notarized agreement) under § 1626a. Unmarried fathers start with no legal custody unless this step is taken.
BGB § 1671 governs custody transfers when parents live separately. For unmarried fathers whose names are not on the birth certificate or who never declared joint custody, the mother holds sole custody by default (§ 1626a para. 3). The father may petition the family court to grant him sole or shared custody—but only after paternity is legally established.
The court will grant the request only if doing so best serves the child’s welfare—especially where joint custody is unfeasible (e.g., due to conflict, distance, or refusal by the mother). If the child is 14 or older, their explicit objection blocks the transfer—even if the father otherwise qualifies.
Statutory TextDie Eltern haben die Pflicht und das Recht, für das minderjährige Kind zu sorgen (elterliche Sorge). Die elterliche Sorge umfasst die Sorge für die Person des Kindes (Personensorge) und das Vermögen des Kindes (Vermögenssorge).

Statutory TextLeben Eltern nicht nur vorübergehend getrennt und steht die elterliche Sorge nach § 1626a Absatz 3 der Mutter zu, so kann der Vater beantragen, dass ihm das Familiengericht die elterliche Sorge oder einen Teil der elterlichen Sorge allein überträgt.

What Courts Have Said
German courts emphasize that a child’s right to know and maintain a relationship with both biological parents is constitutionally protected—even when parents are unmarried.
The court affirmed that children have a fundamental constitutional right to know their biological father’s identity. A mother cannot withhold this information; the court may order paternity testing and disclosure to enable the father’s path toward custody or visitation rights.
What to Do
Establish legal paternity through voluntary acknowledgment (Vaterschaftsanerkennung) with the mother at the registry office—or via court-ordered paternity determination.
File an application at the local Familiengericht requesting joint or sole custody under BGB § 1671.
Provide evidence showing your active involvement, stability, and how custody supports the child’s well-being (e.g., school records, witness statements, parenting plan).
If the child is 14 or older, obtain their written consent—or prepare to demonstrate why the transfer remains in their best interest despite objections.
