If you received a letter from a lawyer claiming that you defrauded your grandmother into signing title to her home into your name, you need to contact the real estate lawyer who assisted in getting title transferred from her name to yours about what you just received.This lawyer should be hired by you to respond to the letter just received. You do not want to respond on your own. To do so could cause more harm than good.Fortunately the prior title transfer was done under advice of counsel for you.Potentially you grandmother may have a claim to get title back into her name claiming duress, fraud, undue influence or lack of capacity. Speak with your prior lawyer about what has happened. He or she will be in a better position to safeguard your interests.Good luck.
