WHEN THE SILVER BULLET HITS THE CMS
How the Child Maintenance Service can be “played” — and how breaches of contact become immediate financial punishment
When the Silver Bullet tactic is fired, one parent removes the other from meaningful contact through allegations, sudden safeguarding claims, or a new narrative that “contact has stopped”. The Family Court may take months to test the truth. CMS can change money quickly because it is designed to calculate maintenance from income and overnight care patterns — not to decide who is right in a contact dispute.
That creates a harsh reality: the same act that blocks a child from staying overnight can also increase the payer’s liability — before any court has resolved whether contact was wrongfully withheld.
1) CMS counts
overnights , not “what the order says should happen”
CMS calls it shared care when the child stays overnight with the paying parent, and that affects the maintenance calculation. CMS will ask both parents for evidence of shared care and can accept a court order as evidence — but the system is still fundamentally built around the pattern of overnight stays used for the calculation, not enforcement of contact.
So when a Child Arrangements Order is breached and overnights are blocked in practice, the paying parent can end up in a position where:
• the order says one thing,
• the reality becomes another, and
• CMS adjusts money around the reality it is presented with — while enforcement of the order lags behind.
This is the “conversion mechanism” of the tactic: contact is disrupted → overnights fall → shared- care reduction disappears → the bill rises.
2) The shared-care bands are the lever (the part most people don’t realise)
Shared care reduces maintenance in bands. For each child with shared care, CMS reduces the weekly amount by:
• 52–103 nights/year: 1/7 reduction
• 104–155 nights/year: 2/7 reduction
• 156–174 nights/year: 3/7 reduction (roughly “3 nights/week”)
• 175+ nights/year: 1/2 reduction plus an extra £7/week adjustment (per child)
So when overnights are removed, CMS doesn’t “pause for truth” — it removes the reduction.
3) The financial benefit when the tactic “works” (clear, quotable numbers)
Below are guide figures for one child using the published CMS percentages (12% up to £800/week, then 9% from £800–£3,000/week) and the shared-care band reduction.
Scenario: shared care drops from about 156 nights/year (3/7 reduction) to 0 nights (no reduction).
• £600/week gross: about £178/month → £312/month (+£134/month)
• £800/week gross: about £238/month → £416/month (+£178/month)
• £1,000/week gross: about £282/month → £494/month (+£212/month)
This is why the Silver Bullet has a financial half: remove overnights and the system can generate an automatic uplift in payments before the court has tested the facts.
4) Costs when breaches take place: “actual nights”, not “ordered nights”
This is the lived injustice: breach the contact order, and the paying parent can still be financially treated as if shared care never existed. CMS is not there to police compliance with a Child Arrangements Order — it is there to apply the maintenance formula using income and shared-care inputs.
So a parent can be hit with:
• loss of the child’s overnight time (through breach), and
• loss of the shared-care reduction (through recalculation),
while the court process to address the breach is slow and often requires repeated applications.
That is why this tactic can feel “profitable”: the breach creates the conditions for a higher bill.
5) The earning-capacity conflict: earn less, pay more
After allegations and emergency “safeguarding” escalation, the targeted parent often faces hearings, legal fees, stress, time off work — sometimes job loss.
Yet CMS generally only expects an income review to be triggered where a paying parent’s income changes by 25% or more (and a change must be reported).
Illustrative example (one child):
• Before: £800/week and ~156 nights/year → about £238/month
• After: income falls 30% to £560/week but overnights drop to 0 → about £291/month
So even with a major income drop, the payable amount can still rise — because the shared-care reduction is removed at the same time. This is the earning-capacity conflict: the allegation harms your ability to earn, while the loss of contact increases what you must pay.
6) The “secondary benefit” problem (why the system can incentivise obstruction)
This is the uncomfortable part, but it’s central to understanding why the tactic persists.
When one parent can control the “reality on paper” (who had the nights), the system can deliver secondary benefits before any truth is established:
1. Higher maintenance via removal of shared care (the numbers above).
2. A stronger position in other “main carer” financial channels. For example, only one person can get Child Benefit for a child — it cannot be claimed jointly.
Whether intended or not, the combined effect can be: restrict contact → increase statutory payments → consolidate “main carer” status in other systems — all while the court is still trying to work out what happened.
7) How to evidence it (a simple tracker that shows cause → effect)
Keep a single timeline table. Make it factual and boring — that’s what makes it powerful.
Silver Bullet / CMS Impact Tracker
• Date allegation / safeguarding trigger appears
• What the order says (overnights ordered) vs what happens (overnights delivered)
• Which shared-care band you drop from (e.g., 156–174 to 0)
• Date CMS is notified / recalculates
• Income change dates (reduced hours / sick pay / job loss)
• Whether the 25% threshold is met and when you requested review
• Court dates / enforcement steps
• Net monthly impact (£)
This turns “he said/she said” into a sequence: justice moves slowly; the formula moves instantly.
8) Fixes that would close the hole
If the goal is child-focused fairness — and removing incentives to obstruct contact — the hole can be closed. For example:
1. Order-anchoring: where a Child Arrangements Order exists, default shared care to the order unless both parents confirm a sustained change (or the court varies it).
2. Disputed-care flag: where contact is actively contested, use an interim position pending court determination, then reconcile later.
3. Income-shock safeguard: fast interim reassessment where earnings drop sharply due to litigation stress/health impacts/job loss, with tight evidence and later true-up.
4. Backdating where wrongful obstruction is found: where a court later finds contact was wrongfully withheld, enable recalculation/credit so the breaching period cannot generate permanent gain.
5. Fairness in child-related entitlements in genuine shared care: explore more transparent and equitable approaches so public support reflects real parenting time and cannot become another lever inside conflict.
Summary line
CMS counts overnights, not truth — and when overnights are taken, the system can convert a breach into lawful income.
Next steps
We intend to examine the CMS element of the Silver Bullet in greater depth as part of our future work — including the shared-care loophole, income-shock delays, and the lack of meaningful remedies where contact is later found to have been wrongfully blocked. We also intend to look at
the fairness of child-related financial entitlements including proposals for more transparent and equitable handling of Child Benefit/child-related support in genuinely shared-care arrangements so that public support reflects real parenting time rather than becoming another incentive embedded inside conflict.
At present, the scale of our wider task is so large that we believe our time and resources are best directed towards progressing LOTTIE’s Law. That is where we feel we can deliver the clearest safeguards and the most immediate protection for children and targeted parents.
If you support closing these loopholes — including CMS reform and fairer handling of child-related entitlements in shared care — please get in touch and clearly state your support. Your messages help us evidence demand, shape proposals, and show decision-makers that this problem is real, repeated, and solvable.
