A family is seeking legal remedies after one sibling, named sole executor of their late mother's estate, has declined to provide any accounting of assets, distributions, or expenditures to the remaining beneficiaries — a situation a MarketWatch reader flagged this week as “zero transparency.”

The executor controls an unspecified estate and has, according to the reader, ignored repeated requests for documentation. The other beneficiaries have not received an inventory, a disbursement record, or any statement of outstanding liabilities.

Estate attorneys are consistent on the remedy: a petition for formal accounting filed in the probate court of the jurisdiction where the decedent resided. Most states impose a fiduciary duty on executors to furnish beneficiaries with a complete inventory and periodic accountings without requiring a lawsuit to compel one.

Courts can order an accounting, surcharge an executor for losses attributable to mismanagement or self-dealing, and remove an executor who refuses to comply. In cases where theft is alleged, referral to a district attorney's office is also available.

The reader's letter does not specify the state, the size of the estate, or whether an attorney has been retained — details that would determine exactly which forms get filed and in which courthouse.

The estate has not yet been taken to probate court. The executor has not been charged with anything.
