haretig says it all.

Another couple advantages of trusts:

1.) wills and probate are public documents, trusts are not. The most famous example being Frank Sinatra, who had everything held in trust. No one in the public really knows how much he was worth when he died.

2) Trusts are not subject to court challenges and suits by disgruntled heirs---wills are, and going to Court is always expensive and to be avoided if possible.

I have probated the wills of 2 estates. No, you don't want to put your heirs through that.
