The term corpus refers to the principal of an estate or trust. Corpus can also refer to the principal of a bond.
The word corpus is derived from the Latin language and means “body.” While it can refer to a human body, it’s also used when referring to a “collection of things.” In finance, the term can refer to the principal of a bond. More commonly, it’s used to describe the underlying assets placed in a trust. In this context, it’s oftentimes used to distinguish between the original capital placed in a trust versus the income derived from this capital, which is an important concept when discussing simple versus complex trusts.
