Marriages are entered into in heaven – but divorced on the ground of justice. It is therefore important for spouses to have an early idea of how this can be done fairly and without harm in the event of a separation.

In the case of international families, the often complex German regulations are supplemented by further questions that can only be clarified with knowledge of the laws of the countries and cultures concerned. In the case of marriages with entrepreneurs and self-employed persons, the disputes also revolve around the economic basis for maintenance and equalisation of gains, i.e. specifically business income and the value of companies or independent practice.
