Which of the following best describes the purpose of the RAP?

The purpose of the Rule Against Perpetuities (RAP) is fundamentally to ensure that estates do not create interests that extend indefinitely into the future, effectively violating established time limits on interests in property. The RAP seeks to prevent future interests from vesting beyond a certain timeframe, which is usually determined as twenty-one years after the death of a relevant life in being at the time the interest is created. This intention is to ensure that property remains marketable and that the ownership can be clearly established within a predictable period.

In contrast, options like validating all future interests or allowing contestation of any future interest do not capture the essential nature of the rule. The RAP is not concerned with the validation of interests but rather with the timing of when those interests may vest. Similarly, while complex estate planning may involve future interests, the primary aim of the RAP is not to encourage complexity but rather to impose clear temporal limits to prevent potential complications that could arise from perpetual interests.
