Onus Curae is a platform for calculating child maintenance and spousal maintenance under Swiss law (art. 276 et seq. and 285 et seq. CC), intended for law firms, advisers and parents. The calculation follows the Onus Curae method, based on the case law of the Federal Supreme Court (BGE 147 III 265).
Law firms and advisers can register, as can parents using the Family profile. Other users access a case by invitation. Each user sees only the cases and data that match their role.
The calculation results are for informational and technical purposes only. Legal and financial decisions remain the responsibility of the parties and their legal representatives.
The Onus Curae platform, the Onus Curae calculation method and the related content are the intellectual property of WSC Olimpo SA, Chiasso, which develops and operates the service. Any reproduction or use outside the service requires the written consent of WSC Olimpo SA.
