If I am a beneficiary and inherit a property and and insurance policy. Can the executor put a large chunk of the money back into the estate without my consent. There are no debts on the house, just an outstanding mortgage.
If you're a beneficiary on a life insurance policy on the deceased then that money is yours - not the estate's - and the executor has no say over how it's used.
If, alternatively, the deceased was a beneficiary on a life insurance policy and there were no other beneficiaries then that money would go to the estate, which would give the executor control.
