> Transfer moves Shares from one Holder to another under a signed Agreement, within the Company’s transfer restrictions.

Transfer moves [Shares](/business/nouns/share) from one [Holder](/business/nouns/holder) to another under a signed [Agreement](/business/nouns/agreement), within the [Company](/business/nouns/company)’s transfer restrictions.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `share` | [Share](/business/nouns/share) | Yes | The Share record to transfer from. |
| `to` | [Holder](/business/nouns/holder) | Yes | The Holder who receives them. |
| `quantity` | `integer` | Yes | How many Shares move. |
| `agreement` | [Agreement](/business/nouns/agreement) | Yes | The signed transfer Agreement. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `share` | [Share](/business/nouns/share) | Yes | The new Share record held by the receiving Holder. |

## Effects
- Emits [`Share.transferred`](/business/events/Share.transferred).
- Performed by the [Legal Lead](/agents/legal/legal-lead).
- One-way: it waits out its delay window, and runs in the `send` and `do` modes.
- Refuses a transfer the bylaws or a right of first refusal block.
- Keeps the original record; a transfer writes a pair of records, never an edit.

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | [Share.transfer](/business/nouns/share/transfer) |
| A transfer the bylaws or a right of first refusal block | [`refused`](/code/api/errors/refused) | Clear what the check names, then call it again. | [Share.transfer](/business/nouns/share/transfer) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Medium: one-way, bounded |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | 1 business hour, in which a watcher can pause, redirect or cancel it; then it runs. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
