What are the types of bequest, and when and how is it written?

Question:
May Allah reward you. The brother Abu Khalid asks about the bequest: when is it written? What are the most prominent rulings related to it? And who writes it?

Answer:
The bequest is of two types: a bequest regarding the rights owed to him and the rights he owes to people, and deposits. These are obligatory; he writes them and hastens to write them, even if he is in good health, so that they are not lost. It is the right of a person not to spend two nights without his bequest being written at his head, as in the authentic hadith.
As for the bequest that is a voluntary gift of some of his wealth after his death, this is a recommended bequest. This is a recommended bequest within the limit of one-third or less, and it is for channels of good. It is recommended, not obligatory.
And the Muslim should make a bequest if he has a lot of wealth, so that he bequeaths something that remains for him after death, and he appoints a supervisor for it. The bequest is written in the Sharia court with the notary. Yes.
