Swiss Civil Code

¹ Where the con­tri­bu­tion made by one spouse to the oth­er’s ca­reer or busi­ness is sig­ni­fic­antly great­er than re­quired in the light of the lat­ter’s con­tri­bu­tion to the main­ten­ance of the fam­ily, he or she is en­titled to reas­on­able com­pens­a­tion.

² The same ap­plies if a spouse has con­trib­uted sig­ni­fic­antly more of his or her own in­come or as­sets to the main­ten­ance of the fam­ily than he or she was ob­liged to con­trib­ute.

³ However, a spouse is not en­titled to com­pens­a­tion if such ex­traordin­ary con­tri­bu­tion was made un­der a work, loan or part­ner­ship agree­ment or on the basis of some oth­er leg­al re­la­tion­ship.
