Which rule in common law invalidates certain future interests in property?

The Rule Against Perpetuities is a fundamental principle in common law that addresses the validity of future interests in property. This rule stipulates that certain interests in property must vest, if at all, within a specified period, which typically cannot exceed the life of a person plus twenty-one years. If an interest potentially extends beyond this timeframe, it is rendered void.

This rule serves to prevent the indefinite restriction of property transfer across generations, promoting the free transferability of property. By invalidating futures interests that could last too long, it ensures that property remains marketable and does not become 'stuck' due to overly complex conditions tied to that property.

In contrast, the other options provided do not pertain to the validity of future interests in property. The Rule of Four pertains to the U.S. Supreme Court's practice of needing four justices to grant a writ of certiorari. The Rule of Construction generally involves how legal documents are interpreted. The Rule of Evidence encompasses the principles governing what evidence can be presented in court. These distinctions underscore why the Rule Against Perpetuities is the correct choice regarding the validity of future interests in property.
