Let's take a simple example of a savings account. Upon your death, the bank would very likely block the account while the Will is being probated. It will not allow any withdrawal from the account without a court order. No ten percent in expenses. And no publicity.
Probate can be particularly harsh on a going business.
It almost always deals it a fatal blow. Most businesses simply come to a grinding halt while the dead man's Will is being probated. However, under a Living Trust, the successor trustee can continue to run the business without having to wait for the ponderous machinery of judiciary to grind out an approval. Your business doesn't become everybody's business. A word about taxes.
