Why might parents need a notary for will notarization?

The correct answer highlights a significant and practical reason for parents to seek notary services when executing a will. Appointing guardians for children is a critical component of a will, particularly for parents of minor children. This legal document enables parents to explicitly state who they wish to care for their children in the event of their untimely passing.

When parents have a will that includes such provisions, having it notarized adds an extra layer of authenticity and validity to the document. This helps ensure that there are no disputes or questions about the guardianship arrangements after the parents' death, as the notarization confirms that the document was signed voluntarily and by the proper individuals.

The other options, while important, do not directly relate to the purpose of a will. Selling property typically involves different legal processes and documentation, obtaining financial advice does not require notarization, and finalizing a divorce agreement usually falls under family law and is not about the provisions of a will. Thus, ensuring proper guardianship appointments is the most pertinent reason for parents seeking a notary while creating their wills.
