The attorneys on JustAnswer are glad to answer questions and give information, but JustAnswer is not a law firm, so we cannot take on client representation and no attorney-client relationship is formed.
Please keep in mind that the law does not always support our position and although I may not agree with the law, I do not write the law and, therefore, cannot control the outcome, So, please remember that does lessen the time and effort I devoted to researching your question and providing you with an Answer,
The Answer I am providing is information only and does not constitute the practice of law in jurisdictions where I am not licensed to practice. This is a public forum on the internet, so I caution you not to include any personal identifying information
The Statute of Limitations has expired for suing your lawyer for legal malpractice in assuring you that it was a legal 3 family house, and for suing the seller.
However, if your lawyer furnished you with a legal document issued by a governmental agency that it is a legal 3-family house, then the municipality cannot come after you for anything, nor deny you the issuance of any document necessary for you to sell the property, if that is what you want to do.
You can also put in a claim with your title insurance company. I do not have the policy in front of me so I cannot say anything definite about whether this claim would be covered or not. However, I can say that you should put in a claim now because if you delay, they can deny on the basis of your delay in filing the claim with them
Please be kind enough to press "ACCEPT", otherwise I do not get paid anything at all
