Final answer:
The question pertains to estate law, focusing on will stipulations and inheritance concerning children born posthumously. It highlights the legal principles of vesting and contingent remainders in the context of property inheritance.
Step-by-step explanation:
The student's question addresses a scenario that involves estate law, specifically concerning stipulations in a will and the rules of inheritance. The scenario depicts G devising land to A's children who are alive 25 years after G's death. An important aspect of this question is the principle of vesting, which refers to when an interest in property becomes fixed and absolute. Here, A predeceases G, yet at G's death, A had living children. The determinant factors are the local jurisdiction's laws addressing posthumous interests and the language of the will itself. If the language of the will creates a contingent remainder in favor of A's children living 25 years after G's death, then A's children who are alive at that future date will inherit the land devised by G.
