Hi @huw,

Your point is well-taken. In scenarios where the incoming controllers of the receiving account are **empty** , the `newOwner` would solely witness the credit/creation of the new holding. However, they would not be privy to the corresponding holding being debited/archived. To rectify this situation, we could incorporate the `newOwner` as choice observers in the following manner:

```haskell
  nonconsuming choice Transfer : ContractId Transferable
    -- ^ Transfer a contract to a new owner.
    with
      actors : Parties
        -- ^ Parties authorizing the transfer.
      newOwnerAccount : AccountKey
        -- ^ Account contract id of the parties to transfer the contract to.
    observer newOwnerAccount.owner
    controller actors, getLockers this
    do
      transfer this self arg

```

I have added a github issue [837](https://github.com/digital-asset/daml-finance/issues/837) where we can track this.

Please also find the following related forum question:

> There is no special inbuilt for custom events as every choice exercise is an event. So if you want to emit an event, you can just create a choice without an effect: controller (signatory this) can nonconsuming MyEvent : () with message : Text do return () If you exercise that, all you’ll get is an extra node on the transaction tree that you can react to.

I hope that helps.

Johan
