It sounds to me like you have a parent of a new team member, and this parent is operating as if the parent relationship "by default" entitles them to assume a mentoring role, which might actually be appropriate for them to do, but only if they complete formal process for becoming a team mentor.

So, as already suggested,, an existing mentor should tell them to complete the process by which your team accepts new mentors. or back off from assuming that kind of a role.

Our team has a "steering committee" on which several parennts participate, but they do so on a separate basis from the team mentoring role.
