How do we protect the property or money while choosing an executor or other fiduciary is unresolved?

Until the authority question is settled, keep the property secure and insured, avoid unauthorized payments, and document what is done. For this legal issue, co fiduciaries can provide checks and balances but can also slow decisions if signatures or agreement are required. Look for a fiduciary who is reliable, organized, available, willing to take the role, and capable of managing conflict. Probate and property outcomes can change with state law, trust language, and family rights, so have a lawyer in the state confirm the governing documents and the present court or title status before anyone does something that cannot easily be undone.
