Advance planning is one of the most important steps you can take to protect your loved ones and your assets. However, estate planning mistakes can create serious problems when the time comes to carry out your wishes.
In Arizona, courts often deal with cases where estate planning errors cause confusion, conflict, and unnecessary legal expenses.
By looking at real-life court cases from Arizona, you can learn valuable lessons about what to avoid. Here are some common estate planning mistakes and how you can protect yourself and your family from making them.
Mistake 1: Failing to Update Your Plan
One of the most common mistakes is failing to update your estate plan after major life changes. In the 2020 case of In re Estate of Rodriguez, the Arizona Court of Appeals dealt with a will that had not been updated after the testator’s divorce.
The will still named the ex-spouse as a beneficiary, which led to a legal battle between the ex-spouse and the children of the deceased.
Arizona law automatically revokes provisions for an ex-spouse in a will after a divorce, but other documents like life insurance policies may not be automatically updated.
To avoid confusion and legal disputes, you should review your estate plan regularly, especially after events like marriage, divorce, the birth of a child, or a significant change in your financial situation.
Mistake 2: Not Following Legal Formalities
In another Arizona case, In re Estate of Newman, the court was asked to determine the validity of a handwritten will. The will did not meet the requirements for proper execution under Arizona law, which led to lengthy litigation.
Arizona allows handwritten (holographic) wills, but strict rules apply. The entire document must be in the testator’s handwriting, and it must be clear that the person intended the document to serve as a will.
Even though it is legal to write your own will in Arizona, this case highlights the risk of mistakes when you do not follow legal formalities. Working with a licensed estate planning attorney ensures your documents are prepared and executed correctly.
Mistake 3: Leaving Out a Residuary Clause
A residuary clause directs how to distribute any remaining assets that are not specifically mentioned in your will or trust. In the case of Matter of Estate of Smith, the Arizona courts dealt with a will that lacked a residuary clause.
As a result, certain assets that were not listed in the will had to pass through Arizona’s intestate succession laws, which divided the property in a way the testator likely did not intend.
Including a clear residuary clause in your will or trust is a simple step that can prevent unwanted outcomes. Your estate planning attorney can help you draft language that covers all your assets, even those you acquire later.
Mistake 4: Naming an Inappropriate Trustee or Executor
Choosing the wrong person to manage your estate can lead to disputes and mismanagement. In In re Estate of Johnson, a family member appointed as executor mishandled funds and failed to keep proper records. This led to costly litigation and a breakdown in family relationships.
When selecting a trustee or executor, it is important to choose someone who is responsible, organized, and capable of handling financial matters. You should also talk with your chosen person to make sure they are willing to serve.
In some cases, it may be wise to consider appointing a professional fiduciary, such as a trust company, to avoid personal conflicts.
