Closing sail form by condition

I have a process where there are some info to be confirmed by a user. This user is not the initiator.
Then there is a sail form where the initiator can show if the user has confirmed the info.
If so, I need to close this form. Can I do that by checking the condition within the form and not by exception?
I will to avoid to poll of the status from the database into process.
Thanks
