My husband has approached me wanting a divorce and I don’t have the funds to take on the debt and I wonder if I can ask for a payout

I'm sorry to hear about your situation. We generally do not recommend approaching the insurance company for the purpose of a buy out. This raises red flags for the insurer, making them suspicious of your claim, and they could present more issues for you. They often are not open to the idea of buyouts, unless it's on their terms unfortunately.
