Yes, an executor has the right to decline the role if they are unable or unwilling to fulfill the responsibilities associated with it. Accepting the role of an executor is a voluntary decision, and individuals are not obligated to serve in that capacity.
If an appointed executor declines the role, it is advisable to have a substitute or alternate executor named in the Will. This ensures that there is a designated person to step in and handle the responsibilities. If there is no substitute executor named, the court may appoint a suitable person to serve as the administrator of the estate.
