The obligation here comes from general disclosure law rather than a lead-specific statute: if you know about a hazard that a buyer would reasonably want to know before completing the purchase, failing to mention it can expose you to a legal claim after closing.
If your house was built before 1990 and has original interior or exterior paint, it is worth mentioning that fact and the era of construction to your agent and lawyer before listing, rather than waiting for a buyer's inspector to raise it as a surprise late in the process.
Disclosure here is about known, material facts, not a specific mandated checklist, so when in doubt the safer move is telling the buyer rather than hoping it does not come up. Get your hand-reviewed valuation from Joel Dyck.
