What can I deduct in the "Extraordinary fees" category?

Non-reimbursed medical expenses (neither by the CNS nor by your private/supplementary health insurance company)
Expenses due to legal maintenance obligation
Civil litigation fees (attorney's fees)
Divorce fees
Funeral expenses
Dietetic regimes (only with prescription)

Extraordinary expenses are deductible from a certain minimum amount, which is defined depending on your taxable income.
