Swiss Civil Code

¹ If the leg­al rep­res­ent­at­ive does not grant ap­prov­al, either party may de­mand resti­tu­tion of any per­form­ance already made. A per­son lack­ing ca­pa­city to act is however only li­able to the ex­tent that he or she has already be­nefited from the per­form­ance or to which he or she has been en­riched at the time of the de­mand or has ali­en­ated the be­ne­fits in bad faith.

² If the per­son lack­ing ca­pa­city to act has in­duced the oth­er party to er­ro­neously as­sume that he or she has the ca­pa­city to act, he or she is li­able for the dam­age in­curred.
