Am I allowed to make a will in Israel leaving my estate to my gay partner? I am HIV positive, but not ill now, but am anxious to know he won't have trouble getting probate if I become ill and die.

Of course  you can leave your property to your gay partner, after you die. There is nothing in Israeli law preventing you from bequeathing your property just because he is your homosexual partner.

You, as any testator, are free to bequeath your property to whoever you wish, providing you are of sound mind when you make your will,are not under pressure,trickery, duress, or undue influence etc. It may be advisable to have documentation about your legal capacity to make a will because of your illness, so as to counter any possible challenges, later. If your physical and emotional condition is bad when you make the will, it could be challenged on the grounds of undue influence on the part of your partner, if you are very frail, isolated and dependent on him.

Accordingly, you would be advised to make your will earlier than later, when you are still strong, and not weak. Incidentally, you are always free to alter, or cancel any will you make. You would be advised to sign the will infront of two witnesses,and even deposit a copy with the Inheritance Registrar. It may be advantageous to let a lawyer draft the will, and authorise your signature,in case it is challenged later.
