The gift between spouses, also called "gift to the last survivor" is very often used by couples wishing to increase their protection in the event of death. But this institution is little known abroad. It is unknown under some law systems, while others prohibit it. Moreover, in an international context, a gift between spouses can raise difficulties. To avoid such difficulties, it often appears wiser for a couple owning assets abroad or living abroad or when at least one of the partners is of foreign nationality, to make wills. Spouses may establish themselves by will reciprocally as sole legatees. Thus the objective sought by the gift between spouses, namely to increase the protection of the surviving spouse, will be achieved.
