A person who shares an inheritance with others, typically as a joint heir.
After their parents passed away, the siblings became coparceners of the family estate.
Coparcener → It is formed from "co-" (meaning together) and "parcener" (from Old French *parcenier*, meaning to share or divide). The word refers to individuals who share an inheritance or property together.
Think of people 'together' ('co-') sharing or dividing something ('parcener') — that's what a coparcener is.
