A person who shares the responsibility of carrying out someone's will or managing an estate alongside another executor.
From the prefix 'co-' (meaning together) combined with 'executor,' which derives from Latin 'exsequi' (to follow through or carry out). The term emerged in legal English during the medieval period when estates became complex enough to require multiple administrators.
The job of coexecutor exists because nobody wants one person making all the decisions about a dead person's stuff—it's like having a co-captain in sports to keep things fair and honest, except for managing inheritances and property.
