What type of will is typically considered invalid for real estate transfers due to its oral nature?

A nuncupative will is typically considered invalid for real estate transfers because it is an oral will, not a written document. In many jurisdictions, including Minnesota, the law requires that wills be in writing for them to be legally recognized, especially when it comes to the transfer of real property. Nuncupative wills can sometimes be valid for personal property or in very specific circumstances, but they generally lack the legal standing necessary to convey real estate.

In contrast, a witnessed will, a statutory will, and a holographic will all meet the criteria of being in written form, which makes them valid for real estate transfers. A witnessed will is signed in front of witnesses, a statutory will follows a form provided by law, and a holographic will is handwritten by the testator. Each of these forms has specific legal requirements that ensure their validity in the context of real estate transfers.
