In the context of domestic violence, the separation is a sensitive period. Multiple challenges exist. The first relates to the security of the victims, adults and children. The second, relates to the parenthood. Conjugality and parenthood being intertwined, our interventions have to take into account this very specific context and propose two lone-parenthoods.
