7 Estate Planning Mistakes You Cannot Afford to Make

The Mistakes That Cost Families Everything

Estate planning is one of those tasks that most people know they should do but keep putting off. And when they finally get around to it, many make critical mistakes that can unravel years of careful financial planning.

Mistake #1: Not Having a Plan At All

The biggest mistake is also the most common. According to Gallup, only 46% of American adults have a will. That means more than half the country is leaving their family legacy up to state law.

Mistake #2: Forgetting to Update After Life Changes

Marriage, divorce, births, deaths, moves to a new state — any of these should trigger a review of your estate plan. A will written before your second child was born might not adequately provide for them.

Mistake #3: Ignoring Digital Assets

Your email, social media, cryptocurrency, online businesses, and cloud storage all need to be accounted for. Without access credentials and clear instructions, these assets can be lost forever.

Mistake #4: Not Funding Your Trust

Creating a living trust is only half the battle. You must actually transfer your assets into it — a process called "funding." An unfunded trust is essentially useless.

Mistake #5: Choosing the Wrong Executor

Your executor should be organized, responsible, and ideally younger than you. Choosing an elderly parent or an irresponsible sibling can create chaos.

Mistake #6: Overlooking State-Specific Laws

Estate laws vary dramatically between states. A plan that works perfectly in Texas might fail in California. Always work with an attorney licensed in your state.

Mistake #7: Keeping Secrets

If no one knows your plan exists or where to find it, it might as well not exist. Tell your executor where your documents are stored and give them basic information about your wishes.

What This Means For You

Review your estate plan annually and after any major life change. Keep documents organized and accessible to your designated representatives.
