What should am going to do on my house before living in the nursing so that the state can not get it can I sell my house to my son?

You need to do your estate planning several years before needing to be cared for in a nursing home. The reason is that the state can go back several years and attach property when the owner received government paid medical benefits. You should seek the advice of an attorney to discuss your options and the consequences of transferring your property to your son.

If you simply want to transfer the property to your son then ask that the attorney explain only that issue to you and not an expensive estate planning scheme.
