Can a passport already issued be revoked, not just a new application blocked, over unpaid support?

The Family Responsibility Office's federal licence suspension tool is generally framed around suspending or preventing renewal of a licence like a passport for persistent, unaddressed support default, and this can affect a passport a payor already holds, not only a brand-new application. In other words, having a valid passport in hand at the time arrears build up doesn't automatically protect it from being affected by this enforcement step once the relevant threshold for pursuing suspension is reached.

Because this step is reserved for ongoing, unresolved default rather than a single missed payment, and because FRO gives notice before pursuing it, a payor with a valid passport who is falling behind on support still has an opportunity to address the arrears or arrange a resolution before the passport itself is affected. This is especially relevant for anyone who travels regularly for work or family reasons, since discovering a problem with an existing passport while trying to travel is a far worse position than addressing arrears proactively. Anyone concerned about this should contact FRO or get legal advice promptly rather than waiting to find out at the border or at renewal time.
