If you are allowed to look at the person who died personal records, you want to check bank statements with withdrawals to an insurance company. You must be legally allowed to do that though!
I infer from the question that the answer being sought is: no. A more correct answer would be the reason for the removal of the items, might it be for instance safe keeping (which a duty of the executor) or do you suspect some form of wrong-doing?
The court will appoint someone if no one volunteers.
There is no requirement to 'read the will.' The claim against the life insurance policy can be made any time after the death. In many cases it will not be a part of the estate.
The executor has no right to see the will prior to the death of the testator. The testator may provide the named executor with an unsealed copy or allow the named executor to read the will but that would be entirely voluntary on the part of the testator.
The life insurance proceeds must enter the estate, The Executor of the estate will then determine how, when and to whom it should be dispersed.
Can an executor of will change beneficiaries before or after death
You really don't need to do anything because you aren't the executor yet. If your mother dooesn't change her will before she dies then at that time you can file a declination with the court as the named executor. The court will appoint someone else.
No, beneficiaries do not have to agree on the appointment of an executor. The court makes the appointment. If the family doesn't want someone appointed, the court will likely assign the duties to an attorney or bank.
No actions need to be taken, as your mother still lives. She can modify the will to appoint a new executor. Or when she does pass on, the court can appoint someone else to serve.
Someone else will be appointed the executor. The probate court will appoint someone, usually a bank or attorney, if no one 'volunteers' to do the work.
You can be appointed executor without knowing it. There is no requirement to share the contents of the will before death.
In case of demise of the life insurance policy holder, only the NOMINEE is the beneficiary to get the amount. In case nomination is not done, the legal heir of the deceased person can apply before the insurance authority for the death benefit.
