Appropriation art is a practice, or strategy by which an artist makes use of another work of art, in whole or in part, in order to create a new work. The Tate Gallery has a very good definition and description of modern and contemporary appropriation art.

Cultural appropriation is the practice by which the material, symbolic or spiritual expressions of one culture are taken, adopted, adapted or exploited by another culture. This type of appropriation may be deliberate or inadvertent and often employs stereotyping and other denigrating and exploitative intentions. A subjugated culture often has little recourse to challenge this type of appropriation. In Canada, the colonial framework of copyright law does not adequately address the customary laws of Indigenous cultural expression and traditional knowledge.
Customary laws protect the use of cultural expressions that are specific to a nation or community. These laws can govern designs, music, dance, stories, etc. Some rights could belong to certain families, or be determined by seasonality, spiritual rites, or special events. The context is vast and assumptions should not be made without appropriate consultation.

For further background of cultural appropriation in the context of Indigenous art, read the interview “Dirty Words: Appropriation” from Canadian Art:

If you make use of a work that you do not not own or have permission to use, you may be violating one or more exclusive rights of the work’s copyright holder. This may include making reproductions of a whole work or part of a work, performing or exhibiting a work, or distributing a work.
Infringing copyright has risks and if you are violating copyright you may be presented with an injunction to stop making use of the work, or you may be ordered to destroy the infringing copies. You may also be ordered to pay legal fees in a lawsuit, or pay for the loss of revenue to the copyright holder.
The Art Law podcast has an episode detailing a copyright lawsuit between Lynn Goldsmith and the Andy Warhol Foundation. While based in US copyright law, it is a good introduction to the legal context of appropriation in art.
