The rules
are governed by the Administration of Estates Act 1925, subject to
the power of courts to intervene under the provisions of the
Inheritance (Provision for Family and Dependants) Act 1975. This
means that there are a complex set of rules that focus on passing
an estate to blood relations, spouses and civil partners rather
than other social relations. These rules can be challenged by those
who feel they have been treated unfairly. Spouses, civil partners,
former spouses and civil partners, cohabitants, children,
step-children and other dependants may apply to the court on the
basis that the rules have made reasonable financial provision for
them. The rules are described in more detail on page 10 of the full
report and in Appendix H.
