Marina Is 24 Years Old and Is Planning on Marrying

Marina is 24 years old and is planning on marrying her fiancé. She already has a will, and it names her older sister as her beneficiary. Marina's fiancé, Jared, 32, has been divorced once and has a two-year-old son. Jared also has a will, wherein his ex-wife and son are named the beneficiaries. Should they both draft new wills once they are married, and why or why not?

A) Yes, because both Marina and Jared will likely wish to have wills that name each other as beneficiaries to prevent Marina's assets from going to her sister and Jared's from spending a long time in probate because of legal ambiguity.
B) No, only Marina needs to draft a new will because Jared's ex-wife is no longer his beneficiary because of their divorce, and his son is automatically his beneficiary.
C) No, only Jared needs to draft a new will because he needs to explicitly remove his ex-wife as a beneficiary and designate Marina as his son's guardian in the event of death.
D) No, neither Marina nor Jared need to draft new wills because their marriage legally makes the other spouse their beneficiary, and Jared's son is already provided for.
