Your summary makes no sense. It is not clear what you think the lawyer did or did not do. What does the letter have to do with anything? Why is the sister contesting the Will? Why is the Will no good? What would you sue the lawyer for?
Please feel free to repost this with MUCH more information, and we will try to help.
*** LEGAL DISCLAIMER I am licensed to practice law in the State of Michigan and have offices in Wayne and Ingham Counties. My practice is focused in the areas of estate planning and probate administration. I am ethically required to state that the above answer does not create an attorney/client relationship. These responses should be considered general legal education and are intended to provide general information about the question asked. Frequently, the question does not include important facts that, if known, could significantly change the answer. Information provided on this site should not be used as a substitute for competent legal advice from a licensed attorney that practices in your state. The law changes frequently and varies from state to state. If I refer to your state's laws, you should not rely on what I say; I just did a quick Internet search and found something that looked relevant that I hoped you would find helpful. You should verify and confirm any information provided with an attorney licensed in your state.
Your question is incredibly difficult to understand. A letter by itself has zero legal significance (with limited exception in a support role). Without the Will or at least a copy of the Will, it will be incredibly difficult to prove your position.
Additionally, you have no legal interest in this probate whether or not the Will exists, so only your wife would be able to file a lawsuit.
Lastly, I agree with Attorney Frederick. Please clarify your question and perhaps the community may be better able to assist you. Best of luck.

My colleagues are correct. Your question begs for additional facts and a clear presentation. It may help us to answer your question, if you sit down with someone else to re-write the question. That being said, there are also a lot more questions that come up, including, why do you think the lawyer filed the will correctly. Why is the will being contested? What is the letter? Why is the will not good?
