Living Wills

I own a home. I have been told that if I should go into a coma. The costs will be about $500,000 a year to keep me alive; no guaranty of recovering from the coma, and the home can be confiscated for costs. I would prefer to not be force fed and exist in a coma. I want my daughter (who survived a $125,000 cancer operation, and now cannot afford another such operation, etc.) to obtain my home, in case she needs a place to live or to sell my home for her medical needs. I have heard about a living will and a living trust. What type of trust would insure that my DAUGHTER benefits from my home for her medical needs for today and in the future (and not to be wasted, to keep me alive for one more very painful year by force feeding)?

Declarant A executed a living will prior to a previous surgery indicating his wishes regarding life sustaining measures in the event that he lost the ability to make these decisions. Declarant A has had a change of heart regarding the living will and is scheduled for upcoming heart surgery. What should Declarant A do to revoke the previous living will?

I have a living will and want to revoke it. Is there a formal revocation procedure which I need to follow or is simple destruction sufficient?

I currently have a will on file in Nebraska. The Attorney who made the will is no longer in practice and I would like to make a change to the will. Do I need to have a new one made or may I type up the change I want, have it notarized and register the change? Will this hold up in a probate court? Please let me know if you have a form that I can purchase to make this change.
