Which type of donation refers to the transfer of property due to death?

The transfer of property that occurs due to death is classified as a donation mortis causa. This term specifically describes a situation where a donor gives a gift with the condition that it takes effect only upon their death. This type of donation is often similar to a bequest in a will, as it entails a transfer that occurs after the donor has passed away.

In contrast, donations inter vivos involve the transfer of property during the life of the donor, meaning they take effect immediately and do not depend on the donor's death. The option labeled as "intervivos donation" is simply another way of referring to a donation inter vivos and thus falls under the same category. Lastly, "willing testament" seems to refer to a will, which is a broader legal document expressing a person's wishes regarding the distribution of their assets after death but does not specifically denote the type of donation like donation mortis causa does.
