Hi,
This is my first post so feel free to shoot me down if this has been 
discussed before, but do wizards have wills?
I have wondered since reading OoP what will happen to sirius' 
possesions, ie, the Black family house as its being used as 
headquarters. Will the house pass to blood relatives, ie, Bellatrix 
or Narcissa, or will Harry have claim as he was Sirius' godson, as 
estates often are passed from father to son?
If Sirius did have a will, who do you think he would have left his 
house to? Harry or donated it to the Order? I also wonder who his 
money will go to, as i beleive he has a fair bit that he inherited.
(firebolts aint cheap!)
Plus what legality would there be to this as he was and still is 
considered by the wider ww that he was a criminal in hiding? Other 
than those who were present in the dept of mysteries no one else 
knows he's dead.
Im leaning towards wizards not having will's after Molly's reaction 
to the boggart/dead family members scene. 

"And whats going to happen if Arthur and I get killed, who's g-g-
going to look after Ron and Ginny?"Page 161 OoP Australian edition.

Lupin reassures her that the order would look after the kids, but 
wouldn't that responsibility fall to Bill as the oldest brother?
