Compulsory liquidation (Swedish: tvångslikvidation) means a limited company is placed into liquidation without the owners deciding it. Bolagsverket or a court decides when the company fails certain requirements of the Swedish Companies Act, for example lacking a proper board, not filing its annual report or having used up too much capital.
In a liquidation, the shareholders must be identifiable, for example to distribute any surplus. A correct share ledger makes this possible, and it must be retained even after dissolution.

Liquidation means a limited company is wound up and dissolved.
