Request for Entrusting a Mandate

Custos Fidei does not solicit mandates. Our engagements arise, as a matter of preference, through introduction by clients, multi-family offices, private trustees, and fiduciary advisors who share our standards of judgment and discretion.

We are, on occasion, willing to consider approaches from other quarters. We reserve, without exception, the right to decline any engagement at our sole discretion and without explanation.

All correspondence is reviewed personally. We respond only where we consider a further exchange to be warranted.

On Engagement.

Inspired by Harpocrates, the ancient guardian of silence, Custos Fidei is governed by principles of discretion and restraint. Engagements arise, as a matter of preference, through confidential introduction via our network of trusted correspondents, including multi-family offices, private banking, trustees, and selected fiduciary advisors. On occasion, we are willing to consider direct approaches — though we reserve, without exception, the right to decline any engagement at our sole discretion and without explanation.
