Abstract
The relationship between Jordan and Lie coalgebras is established. We prove that from any Jordan coalgebra , it is possible to construct a Lie coalgebra . Moreover, any dual algebra of the coalgebra corresponds to a Lie algebra that can be determined from the dual algebra for , following the Kantor--Koecher--Tits process. The structure of subcoalgebras and coideals of the coalgebra is characterized.
