Our aunt-in-law passed away and we found a life insurance policy naming my husband, myself, and their down's syndrome adult daughter equal beneficiaries. Her husband, our uncle, is incensed by this and has refused to sign the HIPPA forms for the insurance company to contact his wife's primary care physician. Can he actually prevent this claim from being paid out? We are co-POA's for him, and my husband is the Trustee of his Irrevocable Trust. I am his Health Care Proxy. He is becoming more and more unreasonable and difficult to deal with, going as far as accusing us of taking title to his condo (it has been signed over to his Trust).
