Does the son-in-law need to send an obituary in the circle of friends?

Usually a son-in-law doesn't need to send an obituary in a circle of friends. This is because obituaries are usually published by relatives or colleagues of the deceased to announce the death of the deceased and provide information about funerals and other related matters. As a relative, the son-in-law can post commemorative information about the deceased in the circle of friends, but this is not necessary. Of course, if the son-in-law is willing to share this information in the circle of friends, it is also possible.
