Co-parenting &
patchwork families
Co-parenting and patchwork families practice parenting outside the traditional model—yet Swiss law still recognizes only two legal parents per child, mainly the genetic ones. Other caregivers do not automatically receive parental rights as a result, but may, under certain conditions, assert a right of contact as a close relative (Art. 274a of the Swiss Civil Code). Stepparents have a legal duty to provide support to their partner’s children in everyday life (Art. 299 of the Swiss Civil Code) without thereby becoming legal parents—full parental status is established only through the adoption of a stepchild. We draft clear agreements regarding care, visitation, child support, and inheritance rights so that all parties involved—biological parents, foster parents, and children—are legally protected.

Co-parenting refers to situations in which adults consciously choose to raise a child together without being a romantic relationship—for example, two friends or a couple together with another person close to them. Swiss law currently recognizes only two legal parents per child: the mother who gives birth to the child and the biological father—through marriage, acknowledgment, or a court ruling—or, in the case of married female couples, the second intended mother pursuant to Art. 255a of the Swiss Civil Code. Current law does not provide for legal parenthood involving three or more parents; corresponding demands arising from practice are being discussed politically but have not yet become law. We draft agreements that set forth the roles and expectations of all parties involved as bindingly as the current legal framework permits.
A person who is not the child’s legal parent but has a close, ongoing relationship with the child—such as a known sperm donor who plays an active role, a former stepparent, or another co-parenting figure— may, under certain circumstances, assert their own right of contact as a “close relative” (Art. 274a of the Swiss Civil Code), provided that this serves the best interests of the child. However, this right of contact does not constitute a right of custody or a right to participate in decision-making and is subject to review by the authorities and the courts on a case-by-case basis. We advise on which agreements can be structured in a legally sound manner and on the limits of what is feasible.
Stepparents do not automatically become the legal parents of their partner’s children as a result of their new relationship or marriage. However, the law does provide for a duty to assist: According to Art. 299 of the Swiss Civil Code (ZGB), the spouse of the parent with custody must assist that parent in the exercise of parental care toward their children in an appropriate manner and represent them in everyday matters to the extent that circumstances require. Full legal parenthood—with all rights and obligations—arises only through the adoption of a stepchild; this generally requires the consent of the other biological parent or that the parent-child relationship no longer exists for legal reasons.
In blended families, multiple child support obligations often overlap—for example, toward children from a previous relationship and toward new children born to the couple. Since the 2017 revision of child support law, minor children generally take precedence in the order of priority for child support claims (Art. 276a of the Swiss Civil Code). We calculate and negotiate child support arrangements that take this order of priority into account and create a fair, manageable solution for all children involved.
INHERITANCE PROVISIONS FOR STEPCHILDREN
Stepchildren have no legal right to inherit from their stepparent unless they have been adopted by that stepparent. Protection can be provided through a will or an inheritance agreement, though the statutory entitlement of one’s own children and spouse must be taken into account. For blended families, we assess which combination of a will, an inheritance agreement, and, if necessary, adoption most reliably achieves the desired level of protection.
INTERNATIONAL CONSTELLATIONS
Particularly in blended families and co-parenting arrangements, as experienced in an international setting like Geneva, different legal systems often intersect—whether due to the different nationalities of those involved, changes in residence, or assets held abroad. We clarify international jurisdiction and the applicable law at an early stage.
Co-parenting and blended-family situations are legally complex because the law often does not accurately reflect the reality of family life. We translate this reality into clear, enforceable agreements—covering custody, visitation, child support, and inheritance—and represent all parties with discretion and strategic foresight, without the need to go through an anonymous firm. With us, you speak directly with the attorney. When necessary, we draw on our specialized network, such as professionals who provide psychological support to families. We operate in both German- and French-speaking Switzerland and also reliably assist families with international backgrounds.
No. Under current Swiss law, there can be no more than two legal parents per child. Other caregivers can only secure their role through a contract and visitation rights they may have, but not through legal parenthood.
A right of contact as a “close relative” under Art. 274a of the Swiss Civil Code (ZGB) is possible, provided it serves the best interests of the child. This does not constitute a right of custody or a right to participate in decision-making and is assessed on a case-by-case basis.
No. However, they do have a legal duty to provide support in everyday life (Art. 299 of the Swiss Civil Code). Full legal parenthood is established only through the adoption of a stepchild.
Minor children generally take precedence in the order of priority for maintenance claims (Art. 276a of the Swiss Civil Code). We calculate the maintenance arrangement taking into account all affected children.
No, without adoption, there is no legal right to inherit. A will or inheritance agreement can provide the desired protection, subject to the applicable statutory shares.
