A Mckenzie Friend (named after the case Mckenzie v Mckenzie) is one who who assists a “litigant in person” (LIP) without being party to proceedings or qualified to act as legal representative.
This saves the cost of legal representation.
McKenzie Friends are not permitted to act outside of court nor to sign NTQs or any legal documents.
A McKenzie friend is not normally allowed to speak directly to a judge (rights of audience) at court but in exceptional circumstances may be permitted to do so with the LIP in attendance.
A McKenzie Friend is permitted to consult quietly with the LIP on points of law, procedure and to flag up points a litigant might want to raise in court or questions the LIP should ask of witnesses at court.
