Do I need a trust if I have a will?

Not necessarily. A will alone is enough for many people, but a trust adds benefits a will can't, like avoiding probate, keeping your affairs private, and managing assets if you become incapacitated. Trusts are especially helpful if you own property in multiple states or want to control how and when heirs receive money. If your estate is simple, a will plus beneficiary designations may be all you need.
