The short answer
Joint parental responsibility does not automatically mean equal sharing of day-to-day care. In an alternating care arrangement, both parents look after the child according to an agreed schedule. Whether this arrangement is appropriate depends on the child’s best interests and the specific circumstances — not simply on one parent’s wish for a mathematically equal division.
Parents who separate should therefore distinguish between two questions: who has legal responsibility for important decisions, and what will the child’s everyday life actually look like after separation?
Parental responsibility, custody and day-to-day care are not the same
Parental responsibility primarily concerns responsibility for major decisions in a child’s life. Custody and care arrangements, by contrast, concern the organisation of everyday life. Even where parents share parental responsibility, the child may live mainly with one parent.
Alternating care does not have to mean an exact 50/50 split down to the minute. What matters is a sustainable allocation of care. A calendar alone, however, does not settle either where the child’s main home is or how financial responsibility is shared.
What makes a care arrangement sustainable
Under Swiss family law, the possibility of alternating care must be considered where the statutory conditions are met. This does not create an unconditional entitlement to a particular arrangement. The assessment takes account, in particular, of the following factors:
- Can both parents reliably provide the care required?
- How have care and everyday life been organised so far?
- Are the parents’ homes compatible with school, childcare facilities and social contacts?
- Can the parents exchange essential information and coordinate everyday life?
- What are the child’s needs in light of their age, development and individual circumstances?
- How should the child’s views and relationships be appropriately taken into account?
Conflict between the parents does not automatically rule out every shared care arrangement. An important consideration is whether the conflict actually places a burden on practical cooperation and on the child. Equally, equal parental rights alone do not justify an equal division of care.
Why a child’s best interests cannot be reduced to a percentage
An arrangement that looks balanced on paper can be difficult in practice: long journeys to school, changing working hours or frequent handovers may put strain on a child. Conversely, alternating care can work well where both households are reliably organised and the child enjoys a stable routine in both homes.
A parenting plan should therefore do more than count overnight stays. It should also cover holidays, illness, days without school, handovers, homework and communication with schools or childcare facilities. The more specifically these issues are discussed, the less need there will be for disputes under time pressure later on.
Does a 50/50 care arrangement eliminate child maintenance?
No. An approximately equal division of care does not automatically remove the obligation to provide financial maintenance. Care and financial contributions must be considered together. Income, ability to pay and the child’s needs remain relevant.
Different financial contributions may be appropriate even when each parent provides the same number of care days. For example, their incomes may differ substantially, or certain costs may arise in only one household. Basic expenses such as health insurance and school costs are not simply divided according to the number of overnight stays.
Agreeing a care arrangement with the aim of avoiding maintenance payments risks producing a solution that is sustainable neither financially nor for the child. Maintenance should be calculated transparently, and responsibility for individual expenses should be expressly agreed.
An example from a typical consultation
Two parents would each like to care for their school-age child for half the week. One works changing shifts, while the other has fixed working hours. Their homes are far apart.
The relevant question is not simply whether both parents want to provide care. It is necessary to establish who will actually support the child on school days, whether the journeys are reasonable and what help is available. Depending on the circumstances, a different weekly schedule may make more sense than a rigid changeover every three and a half days.
This example is illustrative and does not predict the outcome of any particular court proceedings.
What parents should prepare before reaching an agreement
Useful preparation includes a realistic weekly schedule, information about working hours and homes, an overview of the child’s expenses and specific proposals for holidays and exceptional situations. The child’s wishes should be appropriately considered without making the child responsible for the conflict between the parents.
Important: A private agreement is not sufficient in every situation. Whether an arrangement must be approved or determined by an authority, and which authority is responsible, depends in particular on the proceedings, the parents’ marital status and any existing decisions.
Three questions about alternating care
Can one parent request alternating care on their own?
A parent may make such a request. Whether the arrangement is ordered is a separate question and requires consideration of the statutory conditions and the child’s best interests.
Does the child have to change homes every week?
No. The specific arrangement must be adapted to the child’s needs and the parents’ circumstances; not every changeover pattern is equally suitable.
Can an existing care arrangement be changed later?
An adjustment is possible where the statutory conditions are met. Unilateral changes without agreement or a necessary decision can, however, create new conflicts.
