Question juridique clé
Whether the wife had to extend her 50% teaching job to 100% and be imputed a higher income.
Solution extraite
Yes. Given her age, long-standing part-time work, the child's age, and the parties' sound finances, a full-time workload was reasonable and possible, with a generous transition period.
Motifs extraits
The duty to increase earning capacity during the marriage follows from mutual support duties. The concrete assessment depends on the parties' circumstances; here the wife already had a long-established 50% workload, was not burdened by insurmountable caregiving duties, and full-time teaching was feasible despite temporary strain.
