Given how far web-based technology has evolved, you might think online legal document services like LegalZoom® and WillsandTrusts.com have advanced to the point where they’re a suitable alternative to having your estate plan prepared by a lawyer.

After all, you’ve been able to prepare and file your taxes online for years, so what makes estate planning so much different? Aren’t lawyers using the very same forms you find on these document websites?

This kind of reasoning is exactly what do-it-yourself (DIY) planning services would like you to believe—but it’s far from true. Indeed, relying on generic, fill-in-blank planning documents can be one of the costliest planning mistakes you can make for your loved ones.

Online planning documents may appear to save you time and money, but keep in mind, just because you created “legal” documents doesn’t mean they will actually work when you (or most importantly, the people you love) need them. Without a thorough understanding of how the legal process works and impacts family dynamics upon your death or incapacity, you’ll likely make serious mistakes when creating a DIY plan.

Even worse, these mistakes won’t be discovered until it’s too late—and the loved ones you were trying to protect will be the very ones forced to clean up your mess or get stuck with a huge nightmare. In part one, we discussed the numerous ways DIY estate planning can go wrong, and here we’ll explain how these generic documents can put the people you love most of all—your children—at risk.
