Importantly, a trust can help you avoid the probate process, unlike a will. However, a trust costs more to set up ahead of time than a will, as you’ll be paying many of the legal expenses at the time you set up the trust. The trust does create far fewer legal costs after your death, whereas the will triggers certain costs as it goes through probate. Unlike a will going through probate, a trust will not become a public document upon your death, allowing you and your heirs to keep your assets private.
