Now you have a relationship with an attorney and have developed some kind of trust with them. That's awesome! (Keep sending them your employment contracts when you change jobs! There are some crazy things in there!)
So you find yourself out on your own and need advice on something really important like if you have to sell your shares of a business you started to your co-founder so they can raise another round. Who are you going to ask? Your trusted attorney who hopefully reviewed your original contract with said co-founder!
