## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Residential Conveyancing & Property](https://ailawframework.com/practice/residential-conveyancing-and-property.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | From the contract and the notices, record the obligation the vendor is said not to have met, whether it is essential, and whether the purchaser has been in possession. List the deposit and any other money the purchaser has paid. Do not draft a termination notice, and do not calculate damages. |
| What the lawyer must review | The lawyer decides whether the vendor has failed in an essential respect and writes any notice. In the 2022 edition sample, if the vendor does not comply with the contract, or with a notice under or relating to it, in an essential respect, the purchaser can terminate by serving a notice. After termination the purchaser can recover the deposit and any other money paid by the purchaser under the contract, and can sue the vendor for damages for breach. If the purchaser has been in possession, a party can claim for a reasonable adjustment. Confirm the printed edition. This is the purchaser's position after the vendor's essential default. It is not the deposit cap and resale after the purchaser's essential default, it is not a notice to complete, and it is not what is refunded on a contractual rescission. |

## Checking plan

**Lawyer review required**

The lawyer checks the purchaser's position after the vendor's essential default. The notice is the lawyer's.

- What the AI does: From the contract and the notices, record the obligation the vendor is said not to have met, whether it is essential, and whether the purchaser has been in possession. List the deposit and any other money the purchaser has paid. Do not draft a termination notice, and do not calculate damages.
- What the lawyer does: The lawyer decides whether the vendor has failed in an essential respect and writes any notice. In the 2022 edition sample, if the vendor does not comply with the contract, or with a notice under or relating to it, in an essential respect, the purchaser can terminate by serving a notice. After termination the purchaser can recover the deposit and any other money paid by the purchaser under the contract, and can sue the vendor for damages for breach. If the purchaser has been in possession, a party can claim for a reasonable adjustment. Confirm the printed edition. This is the purchaser's position after the vendor's essential default. It is not the deposit cap and resale after the purchaser's essential default, it is not a notice to complete, and it is not what is refunded on a contractual rescission.
- 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. The failure is the vendor's, and it is essential. A notice under or relating to the contract counts.
2. After termination the purchaser can recover the deposit and other money paid, and can sue for damages.
3. A reasonable adjustment arises only if the purchaser has been in possession. The notice is not drafted here.

## 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.
