UI Design | Corrections | Property Host / Registrant information

Use Case
In accordance with regulations, registrants have 14 days to report any changes to their registration. The required updates in the legislation must be completed by the examiners as they may have implications to the pertinent details of the registration. We need the examiners to be able to make changes to a host's entered information as required.

As an Examiner
I want to be able to edit the host information on a **REGISTRATION**.
Fields which should be editable to me are:

- Host Name
- preferred Name
- Host Address (similar to current edit of Rental Address)
- Unit NUmber
- Street Number
- Street
- Site Name (optional)
- City
- Province
- Postal Code
- Location Description (optional)
- Host email address
- Host date of birth
- Tax number
- Phone Number

I want to be able to edit, add and remove all individuals and businesses associated to a registration, which are listed:

Business

For each individual/business listed, I need to be able to:
- remove the individual/business from the registration
- add a new individual/business to a registration
- edit current individuals/businesses on a registration.

To edit an individual, I need to be able to edit these fields:
- Name
- Preferred Name
- CRA Tax Number
- Address (similar to current edit of Rental Address)
- Phone number
- Email
- Role (can either be host, co-host or property manager)

To edit a business, I need to be able to edit these fields:
- Company Name
- CRA Business Tax Number
- Address (similar to current edit of Rental Address)

- Role (can either be host, co-host or property manager)

As an examiner, when I

AS an examiner, when I
save any information changed for the host / individual / business changed,
