survivorship deed

From the limited amount of information you provided, it sounds like you have gotten yourself into a very difficult situation.  Those who have told you that you cannot "revoke" the deed are correct because you have given a present interest to your "friend."  It is not very different from buying a house with your spouse.  They are on the deed, you don't just change that without his or her written approval (signing a new deed conveying his or her interest to you). Depending on the rest of the facts about this property, you may be able to get a court to undo what you have done or you, with the help of an attorney, be able to negotiate your way out of this problem. While there may be a good solution for you, but with the limited facts you have provided, there is not enough to give you a definitive answer as to whether a "simple" solution is available to you.
