Inheritance laws vary based on the presence of a will and the surviving family members. Carmen will inherit everything in scenarios a1, a2, a3, b, and e. James Jr. will inherit everything in a3. June will inherit everything in b. John, Rachel, and Albert will each inherit 1/3 of the estate in c. Maria will inherit 1/2 of the estate in d, while Bill, Jill, Tracy, and Tim may potentially inherit portions of the estate depending on the order of deaths.
