I have an oral agreement to perform duties in exchange for sharing in revenue. Over the past 5 months I have worked full time performing services and incurred expense in this arrangement, only to find the other party is dragging their feet on completing the contract. They want to change the terms we agreed on and are not willing to honor our initial agreement. They have received over $50,000 as a result of my efforts and are holding the money. I have gone 5 months without being reimbursed for the money owed and know they have received revenue from my efforts.
How strong of a case, and what options do I have? Should I continue to work through contract language or pull the plug and take legal action?
