Communicating regularly with heirs is a key responsibility of the executor, but if you’re not named in the will they have no need to communicate. If you’re named in the will and there’s no communication, they should be made aware of their responsibilities. You may want to have a lawyer handle this for you. If the executor continues to fail to communicate, you can apply to the probate court for assistance.
The probate court has numerous actions it can take, depending on the evidence, which may include requiring an account of what they have done, removing them as executor, and/or holding them personally responsible for legal costs and estate losses arising from their neglect.
