The Verdict: Need More Info
You may already be Moroccan by descent, so check that route rather than reacquisition. Our Morocco citizenship by descent quiz takes you through it in a few questions.
Moroccan nationality passes from a Moroccan father or mother to their child wherever the child is born, with no limit on generations. A parent or grandparent who took another citizenship almost certainly did not lose Moroccan nationality by doing so.
What it turns on is records: your relative's Moroccan papers and the birth records linking each generation to you.
