When a shareholder of partner in a business dies, their share of the business, for example,. company shares or their interest in the value of a partnership normally forms part of their estate and passes to their beneficiaries. This cover protects the families of the business owners by providing a lump sum to help buy the share of the business when a business owner is diagnosed with a terminal illness, critical illness or dies. This allows the family to receive the full value of the share of the business and allows the remaining partners, shareholders to keep control.
