## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Debt Recovery & Civil Enforcement](https://ailawframework.com/practice/debt-recovery-and-civil-enforcement.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | From the sale agreement, the assignment schedules and the notices sent, trace each debt from the original creditor to the client: list every assignment in the chain with its date, parties and the schedule entry identifying the debt, the date and method of the notice of assignment to the debtor, and the balance at each transfer, and flag any gap, unsigned instrument, unidentified debt or missing notice. |
| What the lawyer must review | The lawyer decides whether each assignment is an absolute assignment in writing that passes the legal right to sue, whether express written notice reached the debtor and when, whether the claim must be brought in the assignee’s name or with the assignor joined, and whether the balance claimed is supported. |

## Checking plan

**Line-by-line review**

Review the complete output at the level of each line, paragraph or clause; check facts, meaning and omissions.

- What the AI does: From the sale agreement, the assignment schedules and the notices sent, trace each debt from the original creditor to the client: list every assignment in the chain with its date, parties and the schedule entry identifying the debt, the date and method of the notice of assignment to the debtor, and the balance at each transfer, and flag any gap, unsigned instrument, unidentified debt or missing notice.
- What the lawyer does: The lawyer decides whether each assignment is an absolute assignment in writing that passes the legal right to sue, whether express written notice reached the debtor and when, whether the claim must be brought in the assignee’s name or with the assignor joined, and whether the balance claimed is supported.
- Who reviews: Responsible lawyer with competence in the matter
- Basis: Practical workflow informed by the linked primary sources; the traffic light and working checks are editorial guidance, not a court classification.
- Why: The level reflects what the work is, the consequence of an error, and how much of the output the lawyer must independently re-derive.

## Checks the lawyer makes

1. Check each schedule entry identifies the particular debt, not only a portfolio.
2. Confirm the notice of assignment was sent to the debtor’s address at the time and keep proof of sending.
3. Reconcile the balance claimed to the balance shown at the last assignment plus any lawful interest since.

## Notes

- These are suggested working checks. Confirm the required checking with the responsible lawyer before work starts; the checking approach does not establish permission to use AI.
