My spouse and I signed a legal seperation agreement over a year ago. I believe my spouse didn't have a lawyer at the time we signed it. Now my spouse has a lawyer, and is now contesting the agreement claiming duress and fraud. The agreement is favorable to me. What are the minimum standards to prove duress and fraud? I believe the facts show I didn't induce my spouse to sign under either circumstance. What should I expect to provide during discovery? What types of information can my spouse lawyer request?
