Questão jurídica principal
Whether maintenance contributions paid for adult children were deductible under Art. 21 let. f LCP
Decisão extraída
Under the cantonal provision, maintenance payments for adult children are not deductible.
Fundamentação extraída
The wording is not decisive in isolation; legislative history, systematics, and harmonization with federal tax law show that the 1992 amendment did not intend to extend deductibility to adult-child maintenance.
