When do financial claims expire after divorce?

They don’t!

There is no time limit  for making financial claims after divorce, and claims DO NOT expire automatically. Unless you obtain a legally binding financial order, a former spouse who has not remarried, can make a financial claim against their ex, years or even decades after the divorce has been finalised.

Divorce alone does not end financial obligations between former spouses. 

To achieve financial closure, couples should seek to incorporate any financial agreement into a court-approved consent order, or allow the Court to decide the financial settlement.
