Avoiding the Top 5 Estate Planning Mistakes

04.07.26

By Carly R. Kolo

Most people skip estate planning because it feels overwhelming, uncomfortable, or like something they’ll get to eventually. And many who create a plan make mistakes that can unravel everything they intended.

Let’s talk about the five most common estate planning mistakes and, more importantly, how you can avoid them.

Mistake 1: Your Plan Is Collecting Dust

Life doesn’t stand still, and your estate plan shouldn’t either. A plan you created ten years ago was built for a version of your life that probably doesn’t exist anymore. You’ve had kids, lost loved ones, changed jobs, moved states, bought property, sold property, and your plan hasn’t kept up.

An outdated estate plan creates gaps. Those gaps turn into courtroom battles, tax consequences, and family tension that can take years to resolve. The fix is simple but requires discipline: review your plan every year, and revisit it immediately after any major life event.

Think of your estate plan like a living document. Because it is.

Mistake 2: You Named the Wrong Beneficiaries or Forgot To Name Them at All

This one is painfully common and devastatingly simple. Your beneficiary designations on life insurance policies, retirement accounts, and bank accounts override whatever your will says. 

People forget to update these after a divorce. They name an ex-spouse. They leave a deceased parent listed. They never designate anyone at all, which means the asset goes through probate, the exact thing most people create an estate plan to avoid.

Pull out every account you own. Check every beneficiary designation. Make sure each aligns with your current wishes and your overall estate plan. This one action could save your family months of legal headaches and thousands of dollars.

Mistake 3: You’re Leaving Your Family Without a Roadmap

Too many families discover after a loss that they have no idea where the will is stored, who the attorney is, what accounts exist, or whether there’s a trust. The grief is hard enough. Forcing your loved ones to play detective while they’re mourning is something you can prevent right now.

Create a simple, organized summary—a letter of instruction—that tells your family everything they need to know, including:

  • Where your documents are located. 
  • Who your attorney and financial advisor are. 
  • The various accounts you hold. 
  • Your wishes for things a legal document doesn’t cover, like personal belongings or funeral preferences. 

Give a copy to someone you trust.

Mistake 4: You Tried To Do It All Yourself

There’s nothing wrong with being resourceful. But estate planning isn’t the place to cut corners with a downloaded template.

Online forms don’t know that your state has specific rules about how trusts are funded. They don’t ask about your blended family dynamics, your business ownership structure, or whether your assets are titled in a way that makes your plan work. They give you a document that looks official and feels complete, but it’s full of holes you won’t see until it’s too late for you to fix them.

The cost of getting this right from the start is almost always a fraction of what your family will spend trying to untangle a flawed plan in probate court. And that’s before you factor in the emotional toll of siblings fighting over ambiguous language, a surviving spouse left unprotected, or a child with special needs losing government benefits because a generic form didn’t account for a supplemental needs trust.

Mistake 5: You Forgot Bad Things Happen While You’re Still Alive

Most people think estate planning is about death. It’s not, at least not entirely. Some of the most critical protections in your plan kick in while you’re still here.

Imagine you’re in an accident or dealing with a sudden medical crisis and can’t speak for yourself. Without a healthcare directive, your family may not have the legal authority to make medical decisions on your behalf. Without a durable power of attorney, no one can pay your bills, manage your accounts, or keep your financial life from falling apart while you recover.

Without these documents, your family must petition a court to get that authority, which takes time you may not have. It costs money that no one budgeted for and adds stress to an already overwhelming situation.
