:Owning a monkey is illegal in most parts of the world. In some places, a permit may be granted for an individual to own a monkey, but these are few and far between, and can be tricky to obtain.
The best way to legitimately own a monkey is to contact a zoo, animal research facility, or other similar institution to inquire about adoption or volunteering opportunities. It is often possible to work with a facility to care for and at least partially adopt one of their animals. This way, people can still have the presence of a monkey in their lives without having to go through the intensive process of having one as their own pet.
