Separation and divorce: the decisions that come first

The most expensive mistake in a separation is rarely made in the divorce application. It is made in what people assume that application does.

Getting divorced ends a marriage. It does not divide a penny. Money is a separate application on a separate timetable. People apply online, pay the fee, receive the final order, feel relief, and stay financially tied to a former spouse for life without knowing it. What follows is England and Wales; Scotland and Northern Ireland differ on both.

The divorce itself is a process now, not an argument

Since 2022 nobody has to prove anything about the other person's behaviour. You state that the marriage has broken down irretrievably and the court treats that as conclusive. You can apply alone or jointly, and your spouse cannot defend it; the objections left are technical, such as jurisdiction.

Two fixed waits follow: around twenty weeks from the application before you can ask for a conditional order, then six weeks and a day before the final one. Current fees and the route are on gov.uk. Treat those twenty weeks as working time: roughly what honest disclosure takes, which is not why the period exists but is the best use of it.

Check that you are legally married before you plan anything

A religious ceremony that did not comply with the formalities of English marriage law may not have produced a marriage at all. In 2020 the Court of Appeal held that such a ceremony can leave nothing to annul, and so no right to a financial settlement, however long the couple lived together and however many children they had.

But two outcomes sit behind that, and the gap is the whole case. A ceremony falling short of the formalities may still be a void marriage, which does carry the right to apply for a financial settlement; only a ceremony the court treats as non-qualifying leaves no marriage and no claim. Which one you had turns on where and how it was conducted, not on whether anything was registered.

The same gap catches unmarried couples. Common-law marriage does not exist in England and Wales: a partner of twenty years who is not married and not on the deeds has no claim from the relationship itself, only one built on property law or the children's needs. Scotland differs, giving a former cohabitant a claim from the relationship itself within one year of separating. If either situation might be yours, take advice on it first: a family law solicitor can tell you which side of the line you are on.

The order of operations, and why the sealed order is the whole point

Until the final order you are still legally spouses, and that status is worth money: inheritance under a will or the intestacy rules, and a widow's or widower's pension. The final order removes it at once, while a pension sharing order cannot take effect until the divorce is final and the order sealed. That window, in which you have lost the entitlement without yet gaining the share, is why solicitors hold the final order back until the financial order is sealed.

A signed agreement, a solicitor's letter, a spreadsheet you both initialled: none of these end anything. What ends it is a consent order, your terms put to the court, checked by a judge and sealed. Until it exists the claims stay open with no time limit, and people are pursued for a share of a business, an inheritance or a pension a decade later. A clean break closes future claims between the two of you; it cannot close maintenance for the children, which stays open whatever the order says. The framework is on gov.uk. And remarry after the final order and you lose the right to apply against your former spouse, unless you had already made the financial application, while they keep theirs against you.

Ask for the pension figures in your first week

Pensions are often the largest asset after the house, and the most frequently given away by accident, because they feel abstract next to a kitchen. The transfer value a scheme quotes usually understates what a defined benefit or public sector pension is worth in retirement, so a spouse who takes the house against the pension may do far worse than the two figures suggest. Schemes are slow: request the valuations the week you decide to separate, not the week a court asks.

A court will not make an order about your children just because you ask

If you can agree where the children live and when they see the other parent, you do not need an order and should not seek one. A court makes one only where that is better for the child than no order at all.

Child maintenance runs on its own track. You can agree a figure privately, and the calculator showing what the statutory formula produces is on gov.uk. Either of you can use the Child Maintenance Service instead, which applies the formula whatever you would have agreed. Applying costs nothing; asking it to collect and pass the money on does, as a deduction from what the receiving parent gets and a surcharge on what the paying parent owes.

What breaks down is never the broad principle. It is Eid and Christmas, birthdays, the handover point, and who holds the passports. Write those down while you are still speaking to each other.

Mediation, and the meeting you will probably attend first

Before applying to court about children or money you normally have to attend a Mediation Information and Assessment Meeting. It is an assessment, not a negotiation: a mediator explains the options and says whether your case is suitable. Exemptions exist, including for domestic abuse: if you are afraid of the other person, say so then. Since 2024 courts question claimed exemptions more closely, can pause a case for mediation, and can order someone who unreasonably refused to engage to pay costs.

Mediation is not reconciliation, and a mediator is not a judge: they will not tell you what you are entitled to, which is why people keep a solicitor in the background. Where the dispute is about the children, the Family Mediation Voucher Scheme puts a government contribution towards the sessions and the mediator applies for it, so ask for it by name. Its funding is renewed a year at a time, so check the current terms on gov.uk.

The mistake that costs the most

It is the clean, cheap, entirely online divorce with no financial order attached. It feels like the responsible, low-conflict choice, and for years nothing happens. Then a parent dies, or a house sells, or a business finally makes money, and a claim arrives that a sealed order would have closed. If you do one thing beyond the divorce, make it that order.
