Can a beneficiary demand an executor to provide a copy of the will and a list of all items in the estate?

Yes, a beneficiary has the right to request a copy of the will and information about the estate's assets. Executors are generally required to provide beneficiaries with relevant information about the estate, including a list of assets and debts. However, the specific laws regarding these requests can vary by jurisdiction, so it's advisable for beneficiaries to familiarize themselves with local probate laws. If the executor fails to comply, beneficiaries may seek legal recourse.
