How to group common (to a list and other input groups) input fields

Here's my scenario - I have the following three input fields:

  • Type
  • Remarks
  • Uploads (Popup which allows users to drop files)

Now, these three fields are associated to a person object. The user has the option to select an existing person (from a drop-down list) or add a new person.

I have laid out the fields in the following manner.

On the top of the page, I have the three fields (type, remarks, uploads) one after the other. Below that, the user has the option to select an existing user (from a drop-down) or create a new user via a form (which is collapsed by default).

However, this can be confusing for the user (for example, if the user does not select a type before selecting a person, the person would be added without the type to the model and this would fail when submitting to the backend).

What would be the best way to structure this form?
