The government might owe your family money.
Here's how to check — free.

Every year, properties are sold at tax sales for more than the taxes owed. That difference — the surplus, or excess funds — legally belongs to the former owner or their heirs. Counties hold it, then hand it to the state, and most families never find out. This site teaches you how to find it and claim it yourself. No catch, no gate, no upsell wall.

Every state does it differently. Start with yours.
