My old man had an IRA at Schwab with beneficiary identified. He also had a couple of life insurance policies with Pru and a company I'd never heard of before and couldn't tell you the name of now. In order of ease of receiving payout, it was definitely:
Company X
Pru
Schwab
How it's easier to collect life insurance than an IRA with a designated beneficiary, I have no idea. But they forced a ton of hoop jumping that shouldn't have been necessary, and to me it was clearly an effort to get the beneficiary to throw up their hands and say, "I'll just leave the money there." Which my mom probably would have done and which I immediately objected to out of principle once I'd determine that seemed to be their goal. I had no preconceived notions about them, but I'll never have an account there. Why would I put my beneficiaries through a process I know to be needlessly painful?
