Can I have an executor removed from a will after 4 years of nothing?

An Executor has a fiduciary duty to properly and fairly administer the estate of the decedent (deceased person). The Executor must distribute the assets of the estate to the beneficiaries and provide a detailed, accurate accounting of the estate. In addition, he or she has a duty to pay all debts and taxes related to the decedent's estate. You should request an accounting from your sibling if you believe your father's estate is not being administered properly. If your sibling does not respond, you should file a Petition to Compel an Accounting by the Executor. The court will issue an order directing the Executor to account within 30 days. You should retain an attorney to handle this matter for you. If it is determined that your sibling is not handling your father's estate properly, you may have grounds to remove him or her as executor of your father's estate via filing a petition to remove him or her. You should speak with an attorney about this matter.

You will not be "removing" the executor since his name will always appear in the will. He is issued Letters Testamentary which gives him power to act on behalf of the estate. If he is not acting then a court can revoke the letters and appoint you. Has he been issued letters?

You can access every New York County's Surrogate' court on the web. If you read the Court's website they strongly suggest if not encourage legal counsel to represent any Executor. The reason is that Executor's sometimes forget their fiduciary duties. If you ask him what that term means and he is unable to answer you then retain an attorney and go to the Surrogate's Court with him or her.
