I am the executor of my father's will in CA. His estate is worth less than 150,000. He has unpaid debts. No assests need to go though probate. No real estate. Car is paid off and qualifies for transfer without probate. His personal property is just old furniture. He has IRA, Life insurance with me as beneficiary, so again no need for probate. However, creditors are saying his estate must pay these debts. How do I prove to them that the estate does not have enough money for payoff (insolvent) and get them to go away? Is there an official document I need to get? Can I get it without dealing with a court? Thank you.
