Is there a minimum arrears amount before the Family Responsibility Office will suspend a licence?

There isn't a single published dollar threshold that determines when licence suspension becomes available; the focus is generally on whether a payor has fallen into unaddressed default and failed to respond to FRO's notices, rather than on hitting a specific arrears figure. A relatively modest but persistent and ignored default can lead toward suspension just as a larger one can, because what tends to drive this step is the pattern of non-compliance, not a fixed numeric trigger.

This means a payor shouldn't assume that a "small" arrears balance is automatically safe from this kind of enforcement, and a recipient shouldn't assume a large balance is required before FRO will act. What matters more in practice is whether the payor engaged with FRO's notices, proposed a resolution, or otherwise addressed the situation before enforcement escalated. Because the exact approach can depend on the specific facts of a case, anyone trying to understand where their situation stands, whether facing possible suspension or wondering why it hasn't happened yet, should contact FRO directly or get legal advice rather than relying on an assumed dollar cutoff.
