A more thorough explanation:

DONATIO INTER VIRUM ET UXOREM

Donatio inter virum et uxorem is a Latin term used in Roman law to refer to a donation between husband and wife. In general, such donations were considered invalid, except for certain exceptions such as suitable anniversary gifts. However, if the donor died without revoking the donation, it might be confirmed.

For example, if a husband gave his wife a valuable piece of jewelry as a gift, this would be considered a donation between husband and wife. However, if the husband later changed his mind and wanted the jewelry back, he would not be able to revoke the gift unless it fell under one of the exceptions.

Another example might be if a wife gave her husband a piece of property as a gift. This would also be considered a donation between husband and wife, and would be subject to the same rules and exceptions.

These examples illustrate the concept of donatio inter virum et uxorem by showing how gifts between spouses were treated under Roman law. In general, such gifts were not considered valid, but there were some exceptions that allowed them to be confirmed if certain conditions were met.
