A more thorough explanation:

For a will to be considered valid, it must be written down. This means that the will must be recorded in some kind of permanent medium, but it does not necessarily have to be on paper.

When someone creates a will, they need to write it down in order for it to be legally recognized. This means that they cannot simply tell someone what they want to happen with their property and possessions after they die. Instead, they must record their wishes in a more permanent way, such as by writing them on a piece of paper or typing them into a computer document.

However, the writing does not necessarily have to be on paper. For example, a will that is recorded on a video or audio recording could still be considered valid as long as it meets certain requirements.

• A handwritten will on a piece of paper
• A typed will on a computer document
• A will recorded on a video or audio recording

These examples illustrate the different ways that a will can be written down. The first two examples are more traditional, with the will being recorded on paper or in a digital format. The third example shows that a will can also be recorded in a non-traditional way, such as on a video or audio recording. As long as the recording is permanent and clearly shows the person's wishes, it can still be considered a valid will.
