Old question, new answer
The answer is "yes", anyone can write a trust, and everybody that owns a home should write a trust and a pourover Will, but that's not the advice most people get from most estate planners. Legalzoom.com advertises on the radio all the time and encourages people to write a Will. Maybe that is a lost leader for them and once you get to their website, they upsell you to a trust (I don't really know for sure). There are many kinds of trusts, but only two classifications. Statutory and non-statutory. Statutory trusts include Living trusts, charitable remainder trusts, generation skipping trusts, etc. There is really on one non statutory trust, but it has many names; common law trust, pure trust, federal trust, unincorporated business trust, etc. The main difference between the two is that the non-statutory trust provides bulletproof asset protection, whereas the statutory trust can easily be pierced by the courts. I have been helping people set up statutory trusts most of my life and only in the last two years, earnestly began to study the benefits of non-statutory trusts. I continue to provide both kinds of trusts software, but encourage people to compare the differences before the decide which one to write. I non-statutory trusts never has to stand up in court because the court has no jurisdiction over non-statutory trusts.
Search Google for, (the best reason to write a trust), without the brackets and only two websites have an answe, and they are both mine.
