Medium- and long-term corporate planning regularly includes the areas of research and development, production and sales, as well as investment and financing. A comparable planning horizon should also exist for inheritance cases or succession, but in practice, this is often neglected. In extreme cases, this can lead to a liquidity drain or capital withdrawal that threatens the existence of the company, as compensation for departing heirs, as well as claims for compulsory shares and inheritance tax, typically cannot be offset by private assets. Julius Lehmann presents possible instruments and design alternatives available to an entrepreneur for both the event of death and during their lifetime, within the framework of voluntary and preemptive succession, to avoid inheritance disputes and unwanted successors. Civil, tax, and corporate law aspects are addressed, and particularly selected options are introduced that can enable a liquidity- or capital-preserving compensation for departing heirs.
