The subscription is taken a year after you first bought your will. You can find the exact details in your subscription receipt which will be sent upon payment confirmation to your email address specified in the account creation.
Cancelling - what happens?
As long as your will has been printed and signed, it remains completely legal even if you cancel your subscription.
However, if you want to update it you’ll have to pay for a brand new will.
How to cancel
After checkout you can cancel at any time from the manage account page.
