Disposal of cinerary ashes at sea is authorized if it complies with maritime regulations and is carried out more than 300 meters from the coast (decree 2007-328 and law 2008-1350-16 on funeral legislation). It is, however, forbidden in a river or on the beach.
It is also possible to immerse the urn containing the ashes. In this case, the urn must be immersed more than 3 miles from the coast, and you must choose a biodegradable funeral urn (made of salt, cardboard, etc.).
After cremation, the family must declare the date and place of scattering to the town hall of the deceased’s birthplace.
