Creating a comprehensive estate plan is a crucial step in ensuring that your assets are distributed according to your wishes, wealth transfer taxes are minimized, and loved ones are adequately provided for after your death. Some people consider a "do-it-yourself" (DIY) approach to estate planning because they are tempted by the promise of simplicity and cost savings (at least in the short term). However, even though a DIY estate plan may seem straightforward enough, there are a number of pitfalls that can undermine the plan's effectiveness and, in some cases, lead to significant legal complications and expense for your heirs after you are gone.
