A more thorough explanation:

A notarial will is a legal document that directs how a person's estate should be distributed after their death. It is executed in the presence of a notary public and two witnesses. This type of will is considered more formal and secure than other types of wills because it is signed and witnessed by a notary public.

For example, if John wants to ensure that his property is distributed according to his wishes after his death, he can create a notarial will. He would need to sign the document in the presence of a notary public and two witnesses. This will ensure that his wishes are legally binding and will be carried out after his death.
