# Abstract a lease

> Enter key lease terms, clauses, and contacts into Tango from a lease document.

Lease abstraction is the process of entering the key terms from a lease document into Tango. The primary areas are Basic Info, Clauses, and Contacts.

## Basic Info

<Steps>
  <Step title="Open the lease">
    From the lease home, select the lease and click **Lease Details**. You land on the **Basic Info** tab.
  </Step>

  <Step title="Review location information">
    The top section shows location data pulled from the linked location record. These fields are read-only here — to edit them, navigate to the location record directly.
  </Step>

  <Step title="Enter general information">
    Fill in the lease number and other general fields under **General Information**.
  </Step>

  <Step title="Enter key dates">
    Scroll to the **Key Dates** section and fill in:

    * **Current Term Begin / End** — the active lease term
    * **Original Begin / End** — the original lease dates
    * **Rent Commencement / Rent End** — used for recurring cost reporting
    * **Possession Date** — when you took possession (also used as the default accounting schedule start)
  </Step>

  <Step title="Enter area details">
    Fill in **Rentable Area**, **Usable Area**, **Storage Area**, and **Total Building Area**. The **Pro Rata Share** calculates automatically from rentable and total building area.
  </Step>

  <Step title="Enter coding defaults">
    Click the **Coding Defaults** tab and enter the accounting segment codes used for payment and journal entry integrations.
  </Step>

  <Step title="Save">
    Click **Save** before moving to other tabs.
  </Step>
</Steps>

## Clauses

<Steps>
  <Step title="Navigate to Clauses">
    Click **Contract Details → Clauses**.
  </Step>

  <Step title="Add a clause">
    Click **New**. Fill in the **Clause Type**, **Effective Start Date**, **Effective End Date**, and **Status**. If standard language applies, it appears automatically and is not editable.
  </Step>

  <Step title="Save and upload documents">
    Click **Save**. Use the **Upload** button to attach relevant clause documents, which also appear in the lease Documents tab.
  </Step>
</Steps>

## Contacts

<Steps>
  <Step title="Navigate to Contacts">
    Click **Contract Details → Contacts**.
  </Step>

  <Step title="Add an external contact">
    Search for the company, select it, choose the related contact, and click **Link Company Contact**. External contacts such as landlords and property managers are linked this way.
  </Step>

  <Step title="Add an internal contact">
    In the **Internal Contacts** table, click **Add**. Select the role (for example, Lease Accounting - Analyst or Rent Approver), search for the user by name, and click **OK**.

    <Note>Internal contacts must be existing users in the system. They are required for approval workflows to function.</Note>
  </Step>
</Steps>

<Info>Additional abstraction areas include Obligations (maintenance responsibilities), Options and Terms (renewal/purchase/termination options), and Co-Tenancy clauses — all accessible from the Contract Details section of Lease Details.</Info>
