Change description

This work adds the Universal Credit, priority debts, and priority debt details part of respond to a claim. Defendants can say if they applied for Universal Credit (and when), whether they have priority debts, and if so how much they owe and how often they pay. Answers are saved toward householdCircumstances for the API/CCD layer to persist.

Implementation

• New screens: (1) Universal Credit, (2) Priority Debts (with guidance text and Citizens Advice link), and (3) Priority Debt Amounts / Frequency.
• Flow: from “What regular income do you receive?”, users either go straight to priority debts if they said they get Universal Credit, or via the Universal Credit question first. Priority debts then branches to the details screen or skips it; back links from “other regular expenses” follow that path.
• Supporting code: small journey helpers, pence/pounds helpers for money fields, form builder support for tighter layout on those fields, and types for the new case fields.

Screenshots

Testing done

• Jest: unit tests for the new steps, flow routing (priority debts, regular income, other expenses), and the money helper. Run yarn test:unit in pcs-frontend.
