+## Custom statuses
+
+Case Management supports customizable case statuses. By default, cases move through Open, In Progress, and Closed. You can add additional statuses to represent reviews, handoffs, or other workflow steps.
+
+Custom statuses help you:
+- Standardize how work moves through each stage of a case lifecycle.
+- Reflect reviews, handoffs, and intermediate states.
+- Improve reporting and automation by aligning statuses with your processes.
+
+### Create a custom status
+
+1. Navigate to [**Settings > Shared Settings > Case Types**][2].
+2. Select the case type you want to update.
+3. Scroll to the **Statuses** section.
+4. Add a new status under one of the three existing status groups: **Open, In-Progress,** or **Closed**.
+5. (Optional) Set a new **default status** for each status group. Default Statuses are used in automations as the preferred statuses for the group when exact status names are not provided.
+
+<!-- \[Screenshot here\] -->
+
+* Each status group (`Open`, `In-Progress`, `Closed`) must contain at least one status.
+* You can delete an existing status, but you must first migrate any cases currently using that status to another status in the same group.
+* Custom statuses behave exactly the same as Datadog's built-in statuses.
