IS A HANDWRITTEN NOTARIZED WITNESSED WILL LEGAL IN LOUISIANA?
A handwritten Will is called a “holographic Will”. Some state do not recognize such Wills or allow for them but in only limited circumstances. However, LA will does recognize a holographic will if it is written by the testator (ie the person making the Will) and dated and signed by them. No other formalities are required; it does not have to even be notarized. (Section 1588).
Depending on the type of estate you have (simple or more complicated), you may still want to consider having an attorney draft one for you. They can best handle all of the complexities involved and you would have the assurance of having your estate distributed according to your wishes and state law. In lieu of that, you could download a form from the Internet (many sites sell such forms), and then make a more formal Will out yourself. Or you could write your holographic Will (or execute one downloaded as described above), then pay for an hour or so of an attorney's time and have them review it for you.
