Answer: Nuncupative will
Step-by-step explanation:
The nuncupative will, or open or public will, is defined as one where the testator makes known the things he wants to the witnesses. This will do not need to be written, being oral is sufficient for it to be valid, but witnesses are needed for it to be valid. After being heard by the witnesses, this will is going to be written.
As the laws of the countries in many cases are different, the number of people may be different when they are witnesses for this type of will to be valid. In some, the presence of 5 people is required, in others 7, but the fundamental thing is to have people who can corroborate that what the testator expressed is true and that this will come true.
