When considering an Executor, many people will trust one of their own children above all other potential candidates. However, it is not always a good idea to choose one of your children as your Executor, according to Texas Lawyer in "Mamas, Don't Let Your Babies Grow Up to be Executors."
Being an executor is not an easy job. An executor does more than just distribute the assets of an estate. Among other things, an Executor must be able to communicate with the Court and with any heirs about the estate. If, for example, the executor and a sibling do not get along, there can be problems. In some cases, executors will need to invest assets for a period of time before they can be distributed, and the executor need to do that investing wisely. Moreover, an Executor should be financially knowledgeable and not prone to emotional decision-making.
Before naming one of your children to be the executor of your estate, think through whether it is a role for which that child is suited. It might be better, in some cases, to name a professional.
An experienced estate planning attorney can advise you in creating an estate plan that fits your unique circumstances, including choosing the most appropriate candidate for the job of your Executor.
