There are two ways that payment responsibilities can be shared. If the other payer is part of your household, you may choose to share your login information with that individual.
In a situation where personal financial data is not shared, you may forward your email notification to the individual, who will then click on the "View or Pay Now" button and elect to make a one-time payment. The payer will need to enter their name, email address, mailing address, and payment information. They will receive the payment confirmation and you can verify their payment by viewing the invoices in your account.
