No,cassa, those words don't absolve the executor from all liability.They're intended to stop beneficiaries from claiming for each and every loss regardless. For example, shares in publicly quoted companies are valued for probate at the price they were at the death and any inheritance tax is charged accordingly. Obviously the shares might go down in value before the executor gets probate and go down even further afterwards but it usually would be very harsh to hold the executor liable for not gettng probate instantly or not guessing which way they'd go afterwards, before realising them or if they're a specific bequest, transferring them to the beneficiary. The executor cannot get them revalued for tax purposes either. The tax is always claimed at the value at death, not what the shares are ultimately realised at.,
Otherwise the words could be used as an answer to any bad conduct in bad faith tantamount to, or being, fraudulent which causes loss to the estate or beneficiaries.
