Goal and impact

PURPOSE: Assistance is always supplementary to income sources, including alimony. By calculating alimony, the municipality can supplement income up to the assistance level.
IMPACT: A contribution is calculated and imposed. Consequences of this for a Bubger may be that one has to start paying a maintenance contribution.

Considerations

The calculation is always up-to-date due to revision. INA is also used by the judiciary and legal profession.

Human intervention

Data entry in INA programme is checked by quality staff

Risk management

The risks are in the input and handling of the results of the calculation tool. Often the data from the time of separation are not available, and calculations are made using the current situation

Technical design

If you are divorcing your partner, it may be necessary to agree on alimony. This may be the case, for example, if one partner has a job and the other does not. Alimony is meant for living expenses, such as groceries, rent and so on more, so that the partner can live his or her own life. Alimony can also be meant for child maintenance. Do you receive assistance from the municipality? If so, your partner is obliged to give you money for living expenses. You may not have agreed on alimony for this purpose or a court may have imposed it. In that case, the municipality wants to know how much money you get for yourself or the maintenance of your children. If you receive money for maintenance, the municipality may reduce your social assistance benefit. To find out how much money you receive from your ex-partner, the municipality uses a tool on the computer. This tool is called INA. Once the municipality knows how much maintenance money you receive, it can adjust your social assistance benefit. INA's algorithm takes into account your income, the number and age of your children and whether or not you have to pay a lot of rent or a mortgage. Does something change in your situation? Then you have to inform the municipality yourself. The municipality will then recalculate the amount of your assistance.
