Martin Widrig comments on alternating custody in the Tagesanzeiger.He is a lecturer at the Chair of Legal Procedure and Foundations at the University of Freiburg and a profound expert on the subject; he has already written several specialist articles on alternating custody.
His current article concludes that the prevalence of shared custody may have less to do with the willingness of parents than with the willingness of the courts to even consider it.
There is probably still a lot of work to be done before a care model that is considered ideal worldwide finally gets a chance in the Swiss courts.
