Key legal question
Whether the cantonal court arbitrarily refused to impute a higher income retroactively from 2011
Extracted holding
The refusal was not arbitrary because the husband's income had been stable around CHF 2,300 before and after separation and matched the parties' prior arrangement.
Extracted reasoning
Given the constant low income and the couple's former practice of the wife bearing family support, retroactive imputation was not unsustainable.
