You've received good advice thus far and just to reinforce things, it is always a good idea to have a Will (and/or Revocable Living Trust) and a set of up to date auxiliary documents, such as a Springing Durable Power of Attorney, a Health Care Power or Proxy, etc. Some examples -- what if one of the 3 children who was expected to inherit and share becomes disabled, dies, gets into a financial crisis (so his or her share of the house goes to his or her creditors) or a divorce situation (so his or her spouse seeks a share of Dad's house or the equivalent in cash), or if they cease to get along? What is one wants to live there and 2 want to sell? As to rectifying the current title situation, that needs a lawyer to look at things. All of those things is far less expensive and stressful if done sooner rather than later. Depending on the state involved, the smartest thing often is to re-transfer title to a trust, with the 3 children named as its beneficiaries, and have the trust specify what the 3 children now agree should be done when the day comes.
