Shared Care Child Maintenance Explained
Shared care is one of the most important factors affecting child maintenance payments. If you have your child overnight regularly, you could be entitled to a significant reduction. This guide explains everything you need to know about how shared care works in 2026.

What Counts as Shared Care?
Shared care, in child maintenance terms, refers specifically to overnight stays. The Child Maintenance Service (CMS) only counts nights where your child sleeps at your home - daytime contact, no matter how extensive, does not qualify.
To qualify for any shared care reduction, you must have your child for at least 52 nights per year. This works out to roughly one night per week on average.
Important: Holiday contact counts! If you have your child for two weeks in summer (14 nights) plus every other weekend (26 weekends = 52 nights), that's 66 nights per year - enough to qualify for the first reduction band.
The Shared Care Reduction Bands
The CMS uses a banded system to calculate shared care reductions. The more nights you have your child, the bigger the reduction:
| Nights Per Year | Average Per Week | Reduction |
|---|---|---|
| 0 - 51 | Less than 1 night | No reduction |
| 52 - 103 | 1-2 nights | 1/7 off (14%) |
| 104 - 155 | 2-3 nights | 2/7 off (29%) |
| 156 - 174 | 3 nights | 3/7 off (43%) |
| 175+ | 3.5+ nights (50/50) | 50% off, minus £7/child |
These reductions are fractions, not percentages. "1/7 off" means approximately 14.3% is deducted from the standard maintenance amount.
How 50/50 Shared Care Works
If you have your child for 175 nights or more per year (essentially equal time), a special calculation applies:
- Calculate the normal weekly maintenance amount
- Reduce by 50%
- Subtract £7 for each child in the arrangement
Example: 50/50 Care
Parent earns £45,000, 2 children, equal shared care (182 nights each)
- Normal amount: £136/week
- 50% reduction: £68
- Minus £14 (2 × £7): £54/week
In some cases where both parents have similar incomes and truly equal care, this can reduce maintenance to a very small amount or effectively nothing.
Proving Your Shared Care Arrangement
If you and the other parent agree on the number of nights, the CMS will usually accept this without evidence. However, if there's a dispute, you may need to provide proof.
Evidence the CMS may accept:
- A court order specifying the arrangement
- A written agreement between parents
- Calendar records or diary entries
- School records showing collection arrangements
- Text messages or emails confirming arrangements
The CMS will usually try to establish an "expected" pattern of care rather than counting nights retrospectively. If your arrangement varies significantly, they may take an average.
When Shared Care Arrangements Change
Life changes, and so do care arrangements. If your shared care pattern changes significantly, you can notify the CMS to have your maintenance recalculated.
Common reasons for changes include:
- One parent moving further away
- Children starting secondary school
- Work schedule changes
- Children expressing preferences as they get older
Either parent can request a review if the care arrangement has genuinely changed. The CMS will then reassess based on the new pattern.
Shared Care vs Split Care
Don't confuse shared care with split care. They're different:
- Shared care: The same children spend time with both parents
- Split care: Different children live with different parents (e.g., one child lives with mum, another with dad)
Split care involves a more complex calculation where each parent may owe the other maintenance, with only the difference being paid.
Frequently Asked Questions
Do daytime visits count towards shared care?
No, only overnight stays count. Even if you have your child all day every Saturday, this won't reduce your maintenance unless they sleep at your home.
What if my child stays but sleeps on the sofa?
The CMS doesn't require your child to have their own bedroom. As long as they sleep overnight at your address, it counts.
How do school holidays affect shared care calculations?
Holiday nights count the same as any other night. Many parents have more contact during holidays, which can push them into a higher reduction band.
Can the other parent dispute my claimed nights?
Yes. If there's a dispute, the CMS will ask both parents for evidence and make a determination based on what they believe is the genuine pattern of care.
