This lecture introduces the foundational principles of wills and intestacy law. It explains that a will is a legal document allowing individuals to direct the distribution of their assets and name guardians for minors after death. The lecture outlines typical state requirements for valid wills, such as signatures and witnesses, and discusses alternative forms like holographic and nuncupative wills. It further contrasts wills with intestacy laws, which dictate asset distribution according to a statutory hierarchy when no valid will exists. Ultimately, the lecture emphasizes the importance of wills in ensuring a decedent's wishes are honored and potential complications are avoided.
