The short answer is yes—but there is no such thing as a simple Will. Most people need both a Will and an estate plan. Developing an estate plan and drafting a Will involve many practical, legal and tax considerations. The assistance of an experienced estate lawyer is always advisable.
You can make a formal Will or a holograph (handwritten) Will but, in each case, specific rules must be followed. Most people do not know these rules.
In our experience, homemade Wills usually lead to problems in administering the estate. In many cases, the Wills contain errors and are missing important details, leading to issues about the validity of the document or to a court application to interpret the document.
