Can you claim on a 25 yr old policy if it was active upon death in California?

California, USA.

Cleaning out my deceased mother’s house, found my deceased father’s $100,000 life insurance policy. The policy paperwork, proof of policy and details etc, and bank statements showing it was paid through the month he died (July 2000, hit and killed by a drunk driver). The policy was instated June 1998 by CNA, paid through his Bank of America checking account. My mother told me she never cashed in his policy (long story).

I’ve sent an email out to the current CNA company, but I realize they sell/transfer policies and this policy is from 1998-2000 and would’ve gone unpaid after he died…

I am curious what laws are around being paid out in California for life insurance this late…25 years late. Thank you!

P.S. I am saving up to look into hiring someone to assist in claiming this if I can’t figure it out myself, but wanted to ask Redditors if anyone’s got experience around this.

Edit: Thanks for your replies folks! I’ve checked the unclaimed property website in California and claimed other things for my mother, but searching her name/father’s name/my name/brothers name brought nothing up for this life insurance policy. (Brother is disabled, lives with me as caregiver – he didn’t claim it if you think that might’ve been the case.) I have also submitted an inquiry with the National Association of Insurance Commissioners form for locating policies.
