# Reassigning a contract attachment to a master contract

### Why this matters

Contract hierarchies mirror how your contracts actually relate to each other — a lease with its addenda, a framework contract with its individual orders, a master contract with its attachments. If an attachment accidentally slips out of this structure, or if you want to rearrange the hierarchy later, you don't need to delete and re-upload anything. You simply update the **"Parent Contract"** field — all data, tags, signatures and comments stay intact, and the attachment immediately re-appears nested under its master contract.

This saves time, prevents data loss, and keeps your contract overview clean — even months after the original upload.

### How it works

1. In the contract overview, open the attachment you want to (re-)nest under a master contract by clicking its title.

2. Click **"Edit"** in the top right.

3. Click into the **"Parent Contract"** field. A search dropdown opens, listing every contract in your workspace.
4. Type the name of the master contract and select it from the list.

5. If the **"Type"** field is also visible below: make sure it is set to **"Attachment"**.
6. Save your change.

The attachment now re-appears nested under the master contract in the overview, and you can expand or collapse it via the arrow to the left of the master contract.

### Frequently asked questions

**Do I need to delete and re-upload the attachment?**
No. The "Parent Contract" field only changes the relationship — all data, comments, signatures and activity history stay fully intact.

**Can I move an attachment to a different master contract?**
Yes. Simply select a different contract in the "Parent Contract" field. It's exactly the same path as re-nesting.

**Can I turn an attachment back into a standalone contract?**
Yes. In edit mode, remove the entry from the "Parent Contract" field and adjust the "Type" field if needed.

**I don't see the "Edit" button — what now?**
You likely don't have edit permissions on this contract. Contact your workspace admin or check your role under "Settings → Roles & Permissions".

### Good to know

* The change takes effect immediately — no need to reload the overview.
* An attachment can only be assigned to **one** master contract at a time.
* The master contract itself has no "Parent Contract" field — only attachments can be nested.
* When multiple attachments sit under one master contract, you'll see the count as a blue number next to the master contract's title in the overview.
