How difficult is it for a lawyer to get a copy of my deceased son life Ins.poiicy from Pacific Life Ins. company? What kind of Lawyer do I need ?THANK

I was told my son shot himself .He did not know his advisor talked him into a life insurance policy that would pay one million after 3 yrs .of paying 20k each yr.My son told me it was only a investment and he would be helping me out in 3 yrs.with this money from this investment.My son Ryan was only 22 yrs old when his advisor signed him up.This one million went into his trust fund left from his deceased dad, Pacific refuse to give me a copy and so does his advisor which is also my advisor now.My son didn't have a will or trust Docs in his name.
