Yes, it is illegal to sign someone else's name without their consent, even if they live with you. It is considered fraud and can lead to serious legal consequences. It is always best to seek permission before handling or opening someone else's mail.
To sign someone's name with permission, you will sign your name first, add the per procurationem or p.p. designation after your name, and then sign the missing person's name. This is the preferred method of signing.
If your mother want you to pick up a parcel at the post office in her name, then she need to give you a paper of consent to prove this. You need to bring some form of ID for yourself, but you sign the papers with your own name, not her name. To sign with her name, that is considered fraud, although probably not a very bad case of it in my illustration. Regards.
A Clinician must sign for it to be done if you are under a Mental Health Section Act and you consent and your family consent. Otherwise No.
Simple answer is that YOU can't. If they consent to this, THEY have to register it in their name.
If you are not 18 and don't have legal consent, you can't.

You can't possibly think that someone will tell you it is ok to forge a person's signature on a legal document.
You have to prove paternity in court and then get their consent to sign.
That is illegal if the person did not have consent to sign on the person's behalf. That is considered forgery and can be prosecuted as such.
