The following is my answer to a Quora question: “How old should your children be before you name them executors of your estate?”
They may become executors of your estate once they have reached the age of legal majority, which varies from place to place, from as low as 16 years to as old as 23 years of age. Biological age aside, you must also consider that they should be of sound mind, and be credible and reliable. You should not have, as an executor of your estate, someone who has a conviction for fraud or any form of dishonesty, for example. It would be prudent, also, that your executor not be a bankrupt. Your executor should preferably, also not be in frail health since there is no point of an executor that dies before you.
