Do you have a will? (As in, "this is what should happen to my property after my death"?)
If so, since when? What made you decide to draw one up?
How complex would you say it is, on a scale from 1 ("Everything to my sister") to 10 (drawn up by lawyers, detailed accounting of all your belongings, codicils for whom to disinherit should they do X thing or conditions à la "Person A gets object/sum B only if they do C"; basically, the works)?
