In the case of Norton, Executor v. Whiteside in 1915, the Supreme Court dealt with a dispute over a will and testament. The testator had left his property to his wife for her lifetime use and then to their children upon her death. However, one of the sons claimed that he was entitled to an immediate share of the estate because he had reached adulthood before his father's death. The court ruled against him stating that under common law principles, unless explicitly stated otherwise in a will or trust document, beneficiaries do not have rights until after all life estates are terminated - meaning when both parents have passed away. Therefore it upheld that son’s interest did not vest immediately upon reaching majority age but rather only after mother’s death as stipulated by father's will.

The dissenting opinion in the Norton v. Whiteside case was not recorded or does not exist within available documentation. Therefore, a summary of such cannot be provided.
