I am creating an internet business and have taken on a partner to handle techie side of operations. He has consistently missed deadlines and after a year, I still don't have the promised application that was his sole and only responsibility. Instead, he has provided an application that is little more than I could have created in MS Access, and it doesn't have any chance of being the db for the website. It is just a stopgap product.
We have no written agreement (I know, I am stupid). What am I required to do to terminate our partnership? If I compensate him for the product provided, may I prorate it based on my loss of time and ability to get the business off the drawing board and in to the world?
