+# Invalid delegator
+
+The Delegation Manager reverts with `InvalidDelegator()` when the caller isn't the delegator 
+specified in the delegation. 
+
+This error is thrown by the `disableDelegation` and `enableDelegation` contract functions. Only the 
+account that created the delegation can [disable](../guides/delegation/disable-delegation.md) 
+or enable it.
+
+## Solution
+
+Verify that you're sending the transaction from the delegator's account. If the delegator is a smart account, submit a user operation through the smart account.
+
+```typescript
+import { DelegationManager } from "@metamask/smart-accounts-kit/contracts";
+
+// Generate calldata to disable the delegation.
+const disableCalldata = DelegationManager.encode.disableDelegation({
+  delegation: signedDelegation, // Signed by delegatorSmartAccount
+});
+
+const userOpHash = await bundlerClient.sendUserOperation({
+  account: delegatorSmartAccount,
+  calls: [{ 
+    to: delegatorSmartAccount.environment.DelegationManager, 
+    data: disableCalldata,
+  }],
+});
+```
