There is no clear guidance on how often you should review your Advance Decision but we recommend reviewing it every two years and signing and dating it to show this. There is space on the front of your form to do this. This means whoever reads it can feel confident that it still accurately reflects your wishes.
You should also update your Advance Decision if your health changes, if you change your mind about your wishes or if there is a major change in your life (for example you become pregnant). You can easily edit your form by logging back into your MyDecisions account.
