High-net-worth individuals typically require a notary for a will notarization for which primary reason?

High-net-worth individuals often require notarization for wills primarily to ensure the document's authenticity and legal validity, which can help minimize estate taxes. Notarizing a will provides a level of protection against disputes or challenges to the document's authenticity after the individual’s death. A notarized will is less likely to be contested, which in turn can facilitate a smoother transfer of assets and potentially reduce estate tax implications. The formal process also assures that the testator's wishes are clearly documented and respected, helping to prevent litigation that could arise from ambiguities or challenges regarding the will’s validity.

In contrast, the other options do not directly correlate with the primary purpose of notarizing a will. Investing in stocks, establishing a trust fund, or securing a loan are separate financial activities that do not primarily focus on the legal authentication provided through notarization of a will. Notarization specifically addresses the formal recognition required for a will, ensuring it is upheld as the legitimate expression of the individual’s directives regarding asset distribution.
