You have the option to present the waiver to a person to sign, right after they sign up for a plan. At this point in the process we have already captured their Name and Date of Birth. If they are signing up through a landing page they will be redirected to the waiver page.
From the Date of Birth we can determine if they are over or under the age of 18. If under, the signature block will ask for signature of the parent/guardian and both names of parent/guardian and minor will be on the waiver.
