Hi Taxguy - thanks for responding.
I didn't mean to suggest that I would do this without my parents highly involved. My trust was written very clearly without a lot of legal talk. It was designed so that we can pick it up, read it, and know what to do without a lawyer, although we'd be foolish to not seek the assistance of one at the time of a death. Anyway, the trust would be the same for the most part, just change who the trustees and how it gets divided between me and my brother. There are no kids, grandkids, and it's a small estate - under 300,000. I would just do the trust to avoid probate and to update their living will and power of attorney - now that I'm old enough (29).
