This refers to the Inheritance (Provision for Family and Dependants) Act 1975, which gives spouses, former spouses and children (as well as others) the right to claim capital or monthly sums from the estate of a person who has died. It is invariably based on circumstances where the deceased was maintaining the applicant at date of death. The Act gives the family courts the power to terminate the right to make those claims in the future when hearing the financial claims at the time of divorce.
