The Executor of the Will is responsible for following all of the mandates specifically outlined in said Will as to the distribution of an estate.
But if a Last Will and Testament lacks clarity, the decision is not up to the Executor of the Will to interpret those unclear directives nor to make changes to the stated distribution.
If an Executor has questions about the terms of the distribution, those questions should be posed directly to the Probate Court.
If the Executor is not clear as to how best to approach the Probate Court on the matter, it may be wise to enlist the services of an attorney; you can find an attorney for FREE at Standard Legal’s Attorney Find page.
