When you have children, separation is not a transaction to be won. It is a restructuring of one household into two, on the same money, with the children's stability as the fixed point. This page covers only the financial side: maintenance, the home and the practical arithmetic of the next few years. For arrangements about where children live and how time is shared, Cafcass and gov.uk are the right starting points, not us.
This is the hard centre of most parental separations, and no formula makes it painless. What helps is seeing the real numbers early: what each household costs to run, what maintenance is likely to be, and where the shortfalls are, before positions harden.
It is not. The Child Maintenance Service calculation is a published formula based on the paying parent's gross income, the number of children and how many nights they stay. The official gov.uk calculator gives you the figure in minutes, and most parents simply agree an amount around it without the CMS ever being involved.
Courts prioritise keeping children suitably housed, which is why arrangements like a deferred sale (a Mesher order) exist: one parent stays in the home with the children, and the sale or division happens later, at a defined trigger point. It solves one problem and creates others, and it is worth understanding both halves before proposing it.
Every contested step costs money that the two households will need, and research consistently links parental conflict, not separation itself, to worse outcomes for children. Mediation exists precisely for this, it is a fraction of the cost of court, and a £500 voucher scheme currently helps fund it for cases involving children.
What the process will cost by route, whether you qualify for help with court fees, and what mediation costs compared with solicitors and court. Quiet, factual numbers you can look at at your own pace, with no sign-up.
How the CMS formula works with worked examples, who pays the mortgage during separation, how school fees and maintenance interact, and how to make an agreement binding with a consent order. Written from official sources, dated, and free of drama.
When you need a professional, we can introduce you to a vetted family solicitor or an accredited mediator who can conduct the initial mediation meeting (MIAM) that most court applicants need to attend first. With your consent only, and with no pressure at any stage.
