A more thorough explanation:

Definition: Causa lucrativa is a Latin term used in Roman law to refer to enrichment for which the acquirer pays nothing. This can include things like a bequest or inheritance.

Example: If someone inherits a large sum of money from a distant relative they never knew, that would be considered a causa lucrativa. The inheritor did not pay anything for the money they received, but they were enriched by it.

Explanation: The example illustrates the definition of causa lucrativa because it shows how someone can be enriched without paying anything for it. In this case, the inheritor received a large sum of money without having to work for it or pay for it in any way. This is a common example of a causa lucrativa in modern times.
