Yes do what I did and get yourself an estate planner attorney and get your things in order so that nothing can be changed even if you were to fall ill, make sure you assign an Executor or beneficiary. Have it notarized and sealed.

Yes get an attorney to write an ironclad will will that will freeze them out of your holdings and estate. Get a power of attorney that you can trust and that isn't connected to the family and freeze them out of any decision that might be held of your medical condition and mental condition. Don't tell them anything about this the will is secret and between you and the lawyer so find a gay lawyer that specializes in wills and probate of the states from gay people who have medical conditions. The law society should be able to connect you to a lawyer that specializes in this area so don't delay get it done and freeze your relatives out of your holdings they can lick their lips and think that they can manipulate you out of your holdings and and money only to find out that upon your death they have no chance of getting anywhere near your money.

Jeff25, there is a sense of inevitability in your report, as if your sibling could succeed in inheriting your estate, but surely you can take action to ensure that she cannot?

Write a will, with the assistance of a solicitor skilled in wills, making sure that everything you wish from the moment of your death will occur.

Also, arrange now for legal powers of attorney for your affairs to be exercised by whom you wish when or if you become unable to make your own decisions.

Don't delay attending to these matters - each of us could succumb to a life-threatening situation at any moment. I'm reminded of that brilliant, young, gay, HIV+ doctor who was so helpfully active on "The Body" website: overnight we learnt he had died of sepsis.

All these gentlemen have already supplied you with the best advice that I could give you.
I'm so lucky to have had a family that stood by me for everything from the very beginning when I first told my Mom that I was getting really sick in 1987. When I got the results of the test, both my Mom and my Sister sat next to me on the exam table holding my hands. Yes, I cried like a baby, even though I had known that I seroconverted in '83 and that this was inevitable. Seeing it in black and white was still a shock.
My Mother lived to be 100 and never wavered in her support and concern for me. She even quit her lifelong Church when she found out they were debating whether to let "people like me" into Church membership.
All that being said, I have seen what stinkers others have had to deal with in their families many many times from the '80's onwards. It turns my stomach. Don't take that treatment from any of them for one second. From what I know of you in our talks you seem like a VERY decent man. You deserve to be treated as such. I look forward to our next correspondence, Jeff. I could say a lot more, but I'll save it for then. Take care of yourself. Hope we talk soon. Your friend, Kent

For me, having no children seems more of a factor to my family than status or sexuality. It should never be assumed that the nearest blood relative will be the “winner.”
