Swiss Civil Code

¹ Renov­a­tions and re­fur­bish­ments aimed at en­han­cing the value or im­prov­ing the ob­ject’s prof­it­ab­il­ity or ser­vice­ab­il­ity re­quire the ap­prov­al of a ma­jor­ity of the co-own­ers to­geth­er rep­res­ent­ing a ma­jor­ity share in the ob­ject.

² Al­ter­a­tions which per­man­ently hinder or render un­prof­it­able a co-own­er’s use or ex­ploit­a­tion of the ob­ject for its ex­ist­ing pur­pose may not be car­ried out without the con­sent of that co-own­er.

³ Where an al­ter­a­tion would re­quire a co-own­er to bear un­reas­on­able costs, in par­tic­u­lar be­cause they are dis­pro­por­tion­ate to the value of his or her share, the al­ter­a­tion may be car­ried out without his or her con­sent only if the oth­er co-own­ers as­sume such part of his or her share of the costs as ex­ceeds that which he or she may reas­on­ably be ex­pec­ted to meet.
