Investopedia explains Divestiture
For a business, divestiture is the removal of assets from the books. Businesses divest by the selling of ownership stakes, the closure of subsidiaries, the bankruptcy of divisions, and so on.

In personal finance, investors selling shares of a business can be said to be divesting their interests in the company being sold.
