Well, there's two types of trusts. You could create a testamentary trust; that's a trust that you created in your last will and testament and that's only effective after your will goes through probate. Or you can have a living trust, that's a trust that you create while you're alive.
There's different types of living trusts but what most people think of when they think of living trusts is a revocable living trust; that's a trust that you've created while you're alive and you can blow it apart at any time.
People do living trusts for three different reasons; they want to avoid probate, they want to avoid guardianship issues and they're very concerned about privacy. So if those are things that you're concerned about a living trust could be the perfect solution for you.
