What is the opposite/antonyms for 'acquisition form'?

Solution 1:

In a business context the opposite to an acquisition would be a disposal, which can be used to describe items that are sold or otherwise got rid of.

I would expect a "disposal form" to be used to document items leaving a person or business's ownership, with a field to categorise whether it was donated, sold, lost, stolen, etc.

Solution 2:

The appropriate antonym for acquisition in the business world is divestiture or divestment. Similar to disposal but lacks the "associated with garbage" connotation that this word conjures.
