Answers to common questions

What type of information will you provide to these third parties?

We’ll generally need to tell them limited information, such as your name. The law prevents us from disclosing any more information than is necessary to obtain or verify the information we need.

How long will you contact these third parties?

We may continue as long as there’s activity on your account.

How will I know who you contact?

We’ll send you a copy of the contact list once of year. If you don’t receive a list, it means we didn’t contact anyone who we’re required to advise you of.
