# Update third party

> Make your organization the primary lienholder or mortgagee on a policy.

Operation: `update-third-party`

Request that your organization become the primary lienholder on an auto policy, or the primary mortgagee on a home policy. The lienholder or mortgagee details come from your policy update configuration.

It accepts these [input](https://docs.axle.insure/guides/policy-updates/request.md#input) fields:

| Field | Format | What it does |
| - | - | - |
| `effectiveDate` | `YYYY-MM-DD` | The date the change should take effect. Without it, the insurance carrier's own change date applies. |
| `loanNumber` | string | The loan number to record with the change. Without it, the loan number already on the policy carries over. |

Supported insurance carriers and policy types are below, with each one's [`processesInstantly`](https://docs.axle.insure/guides/policy-updates#processesinstantly). For each field, **Optional** means the insurance carrier applies it when sent, and **Not supported** means it isn't sent and is listed in `unsupportedInputs`.
