Tips

  • Write deadlines down as soon as you receive a document.
  • Count carefully: some deadlines run from service, others from the decision date.
  • Don't wait for settlement talks: negotiations usually don't stop the clock.
  • Ask early: some deadlines can be extended, but only if you act quickly.
