Can friends sign the power of attorney for criminal cases instead of family members? There is a family.

According to the law of our country, the criminal suspect has the right to hire a lawyer after being interrogated for the first time by the investigation organ or from the date when compulsory measures are taken. He can hire a lawyer himself or entrust others to hire him on his behalf. If a criminal suspect is detained, his guardian or close relatives may hire a lawyer for him; If there are no close relatives, other relatives or friends may also hire lawyers on their behalf. But some require the signature of family members, which cannot replace the signature.
