You can file a complaint against your lawyer for malpractice because if indeed these were complete falsehoods and your lawyer represented you and not the estate, then he or she should have zealously advocated for you.  However, if the lawyer you speak of is actually the estate's lawyer, perhaps settlement would have been the less costly route and would have been more to the benefit of the estate by preserving as many assets as possible.  Statements told in court are usually consider protected under the theory of absolute privilege. However, if you can prove those statements are false (and you have proof, not just your word), then a simple phone call to your lawyer (not the estate's) will help determine if claiming perjury is a good route (could rise to the person being prosecuted for perjury on the stand) and perhaps a lawsuit by the estate thereafter for reimbursement plus costs.
