A return needs preparation just as a departure does. Family questions include schooling, housing, a spouse’s employment and maintaining connections with the country left behind, particularly if a family member wishes to stay.
Legally, the law governing your matrimonial property may have changed while abroad; foreign decisions or instruments may need recognition in France; and the children’s return requires both parents’ agreement when one stays abroad.
Return mediation helps you decide together; an international consultation reviews your rights.
I support you in preparing your return, as lawyer or mediator.
