# Amend a lease

> Record and track lease amendments using the Change History tab.

When a lease is amended, you update the relevant fields in Tango and create a change history record to document what changed, why it changed, and the impact.

## Update the lease record

<Steps>
  <Step title="Open Lease Details">
    From the lease home, select the amended lease and click **Lease Details**.
  </Step>

  <Step title="Update affected fields">
    Make the necessary changes across the relevant tabs — for example, update key dates on Basic Info, revise option terms on Options and Terms, or update amounts on Recurring Costs.
  </Step>

  <Step title="Save each tab">
    Click **Save** on each tab where you made changes.
  </Step>
</Steps>

## Record the amendment in Change History

<Steps>
  <Step title="Open Change History">
    From Lease Details, click the **Change History** tab.
  </Step>

  <Step title="Review auto-generated entries">
    Certain changes (such as financial updates) automatically generate a change history record. Review any auto-generated entries first.
  </Step>

  <Step title="Create a manual entry">
    Click **New** to add a change history record manually.

    * **Change Type** — categorize the change (for example, Data Change – Non-Financial)
    * **Change Subtype** — provide a more specific category (for example, Area Change)
    * **Impact checkboxes** — check the boxes that reflect the impact of the change (Rent Impact, Area Impact, etc.)
    * **Comments** — describe the reason for the change in detail
  </Step>

  <Step title="Upload amendment documents">
    Click **Upload** to attach the signed amendment or supporting documents. Uploaded files appear in the documents table on the change history record.
  </Step>

  <Step title="Save">
    Click **Save**. The new record appears in the change history list.
  </Step>
</Steps>

## Resubmit for approval

If your company requires lease approval, use the **Reapprove** button on the Basic Info tab to send the amended lease back through the approval workflow.

<Note>Certain changes that affect financial records — such as CPI adjustments — automatically populate a change history record with a type of "Data Change – Financial". Review and complete these records to maintain a full audit trail.</Note>
