Within the toolbox there are a group of tools that help to control the direction and flow of the workflow.
What is the Null Check tool used for?
Sometimes within a workflow you need to stop the workflow if a particular piece of data isn't populated. So for example if you want to send a document to a lender if a lender if present then you may want to stop or skip that step of the workflow if there is no lender present.
Pre-Requisites
Before you use the null check you will need to have placed (or attempted to place) the item you are checking into a variable (e.g. using the Load Work Item tool)
