It would also prevent me from blowing through a lump sum in some ridiculously short amount of time.
The long term payments makes for a good ideal. But my only concern would be could it be lefty behind payable to my heirs: Wife, kids?[/QUOTE]
Last time I checked, no. If you die, any remaining unmade payments revert to the lottery commission. Easy to get around though, form a corporation then claim the prize in the name of that corp. The corp can be passed on after you die.
Your better taking the lump sum in any case. with a little smart but conservative investing you'd end up with more net value at the end.
