A more thorough explanation:

Definition: Coparticeps (koh-pahr-tə-seps) is a legal term that refers to a person who inherits an estate jointly with others and holds it as an entire estate. It is also known as coparcener, which is an archaic term.

Example: If a man dies and leaves his estate to his two daughters, they become copartencers. They both have equal rights to the entire estate and are considered a single heir. If one of the daughters dies, her share of the estate will pass to her heirs or devisee, not to the surviving daughter.

Explanation: The example illustrates how copartencers share an estate jointly and hold it as a single heir. They have unity of title, interest, and possession, but their estate is not subject to the doctrine of survivorship. If one of the copartencers dies, their share of the estate passes separately to their heirs or devisee, not to the surviving copartencer. This is different from joint tenants, who have the right of survivorship, and tenants in common, who hold their shares separately.
