Not a professional, but if you own a home and/or have dependents, you probably should have a trust. You can google your state probate triggers. Probate is just a way for the state to tax you on death. A trust "loop-holes" taxes, gives you power as to who gets your stuff, a health care directive, etc.

A trust may not solve the bitcoin inheritance issue (e.g. transfer of keys)

Multisig with Casa or Unchained capital HELPS resolve this tho.
