If my husband die and he was receiving a pension can someone deplete the pension and give it to hisdaughter?

Normally a pension cannot be "depleted" because it continues based on a person's life. For example, sometimes there are to pension options: first a person can take a pension that ends when they die; second they can take a pension that continues to be paid to their spouse after their death.  In the second case, the amount of the pension received is usually less.  In either case the continuation of the pension is based on the person's life, not on the payout of a specific amount of money.  you can always contact the pension administrator and discuss options.
