The query is vague. IF you mean that you wanted to issue a legal notice on your own to a third party, you have to share facts enabling members to provide you a draft basing on facts stated by you.

Legal notice on what subject.
There is no specific format for legal notice.\
It shall be drafted based on the case in hand and the circumstances.
You may contact a local advocate and express your desire to send a legal notice to someone and let him know the particulars and the subject including the details of the recipient.
