The right of election to take an elective share by a surviving spouse or domestic partner may be exercised only during his lifetime. In the case of a surviving spouse or domestic partner for whom the court has appointed a guardian to manage his estate, the right of election may be exercised only by order of the court making the appointment after finding that the election is necessary to provide adequate support of the surviving spouse or domestic partner during his probable life expectancy.
