I remember that discussion, good for you.
If you're trying to preserve your assets for your heirs, placing everything into a family trust is one vehicle to consider.
Discuss it with a trusted attorney.
As far as heirlooms and keepsakes, I gave most of mine away 20 years ago.
I had enjoyed them for years and felt I'd allow my heirs to enjoy them longer by giving them away before I died.
Money is but a tool, albeit a very useful tool, if used properly.
But, I have far more than I can ever use, so I've began doling my money out, too.
Again, the right lawyer can show you how.
Talk to at least three, think about it, then slowly begin the process.
Humans have a deep seated desire to keep stuff, my wife hasn't yet broken her bond as completely as I have.
All I know is that I'll take a last breath one day, until one day comes, I'll just live the best life I can.
You'll figure it out at your pace.
While you ponder this matter, doling out a few mementos can help you make the big move.
One way to protect your assets, avoid conflict while never doing stupid stuff.
