It is preferable to name no more than 3. If you name more than one person, then they must work together. If your beneficiaries are 2 – 3 children (for example) and all are named as executors, they will make decisions about your estate together.
A single executor may be efficient, but also may act unilaterally without due consideration for beneficiaries’ interests, eg. a desire to receive specific items from your estate.
If you name one person to be your executor, do name at least one alternate, in case something happens to your first choice.
