Divorce with adult children

Written by CalmSplit Editorial TeamReviewed by Ramani GillLast reviewed 13 August 2026England & Wales

Once children are 18 or have finished full-time education, there are usually no child arrangements or child maintenance to sort out. The focus moves entirely to the divorce itself and the finances.

CalmSplit prepares your divorce application for a one-off £159 and can prepare a consent order or clean break order for the financial side.

  • No child arrangements order is needed for adult children
  • Support for a child in higher education can still be relevant
  • Property and pensions become the main issues

See how it works

What is different

  • The application asks nothing about children of adult age
  • There is no Child Maintenance Service calculation
  • University costs and adult children living at home can affect needs
  • Inheritance expectations often surface, though they are not a legal entitlement

The financial focus

Longer marriages usually mean pooled pensions, substantial equity and joint savings. A financial order should record how each is divided, and a clean break stops future claims.

Telling adult children

Adult children often want an explanation and can feel drawn into taking sides. Agreeing what you will each say, and keeping financial detail private, tends to protect those relationships.

Frequently asked questions

No. They are not parties to the divorce and the court does not consult them.
