Should I use a DIY online will or hire an attorney?

It depends on how complex your situation is. Reputable online will services are inexpensive and fine for simple estates — a modest amount of assets, an outright leave-it-all-to-spouse-then-kids plan, and no special circumstances. They're far better than having no will at all. Hire an attorney when things get complicated: a blended family, a special-needs dependent, a business, significant or out-of-state property, potential family conflict, estate-tax exposure, or a desire for a trust with staged distributions. An attorney also ensures the document is executed correctly for your state — improper witnessing or notarization can void a DIY will. A middle path is to use an online tool to organize your thinking, then have a lawyer review or finalize it. Whatever route you choose, make sure it's signed and witnessed exactly as your state requires, or it won't hold up.
