How can you get a copy of a will

I am a California lawyer and each state is different however Arizona laws are often similar to California. With that said, here in California, after death a will is generally filed with the probate Court in the county the decedent resided in. Once filed it is a public record.  Some counties even have on-line access to documents. Having said that, due to the public nature of wills and probate many people opt for living trusts which are typically not public. This is good for people that want to keep their affairs private but bad for people trying to find out about the other's affairs!  Sometimes you need to do some sleuthing to find out if there was a trust. One easy place to check is with the public real estate records in the county the person lived. You can often look up their deed and see if there is something about a "trust" on that deed.  Then you know it's in a trust. Of course, then your work can get harder as you have to somehow figure out how to find out what the trust says! That's a whole other can of worms....  Good luck to you.
