The Verdict: Need More Info
Your claim turns on whether Moroccan law recognises your father as your legal father. Gather any document in which he acknowledged you, and ask a Moroccan consulate whether that link is recognised.
Moroccan nationality passes through a father only where the legal link to the child is established under the personal status law that applies to him, and before the child turns 18.
For a Muslim father, Moroccan family law recognises paternity mainly through marriage. A child born outside marriage can sometimes be linked to the father, for example where he formally acknowledged the child, but it is not automatic. Moroccans of Jewish faith are governed by Moroccan Hebraic personal status law, which has its own rules.
Bring your birth certificate, the acknowledgment if there is one, and your father's Moroccan papers. If your mother is also Moroccan, claim through her instead: a mother passes on nationality whether or not she was married.
