# Linked Fields

Linked fields allow you to create a form whose default field values can be retrieved from a previous submission of the same form or another form. This can be useful when you want to load default data from a user's previous submission and allow them to edit that data.

For example, you could have two processes, a membership request process and a membership renewal process. During a membership renewal, you may want the user's original request data to be loaded by default and have them change the details where necessary.

To implement linked fields:

* You need to ensure you have at least one [Form Submissions Selection](/managing-services/managing-forms/using-the-form-builder/form-field-types.md#form-submissions-selection) field that will allow the user to select a previous submission
* For each field you want to link to this previous submission, select a linked field that is present in the form chosen in step 1 above.
