An inherited septic system carries a specific risk: it may not have been actively maintained in the years before the transfer, especially if the previous owner was older, in declining health, or the home sat vacant, and an estate transfer often moves faster than a normal sale, with less due diligence built in by default. Getting the system inspected and finding its permit record are worth doing deliberately, since nobody else in an estate transaction is necessarily going to do it for you.
Court-ordered and certain estate transfers are exempt from some state time-of-transfer inspection laws (Iowa's law, for example, exempts several categories of non-market transfers), which means the legal trigger that would normally force an inspection on a typical sale may simply not apply here. That makes it more important, not less, to arrange one voluntarily before you sell the property or move in.
If you plan to sell the inherited property rather than live in it, get the inspection and pull the record before listing; it gives you accurate information for pricing and disclosure, and it prevents a buyer's inspection from surfacing a costly surprise you had no way to anticipate. If you plan to keep and live in the property, the same inspection tells you what you're actually taking on before you're relying on the system daily.

Not necessarily by law, since estate transfers are often exempt from the transfer-inspection laws that exist in some states, but it's still worth doing before you list, for accurate pricing and disclosure.
The same way any buyer would: through the county or district health department that issued the original permit. See our guide on finding septic records.
That's common with long-tenure or elderly owners. An inspection (including a pump-out) is the fastest way to find out its actual current condition rather than guessing.
