Coughlin v. City of Pierre (1939)
Citation: 66 S.D. 523; 286 N.W. 877 (1939) · Court: Supreme Court of South Dakota
A foundational South Dakota authority on the consequences of a void tax title and the equity-of-redemption / do-equity condition attached to setting one aside. The Court held that the holder of a void tax title has no substantive rights in the land except as conferred by statute (caveat emptor governs tax sales), but that an owner seeking equitable relief against the void title must, as a condition, reimburse the purchaser — capped at the delinquent tax plus interest, not the inflated resale price.
Facts
Real property owned by the defendant was sold at tax sale and deeded to the county. The plaintiff (Coughlin) later purchased the property from the county at a resale held under Chapter 83 of the Laws of 1937 and brought an action to quiet title. The trial court concluded the tax title was void, but conditioned relief to the defendant (the former owner) upon the defendant paying the plaintiff $174.80 — the amount of delinquent taxes due at the time of judgment.
Holding
The Court held that the rule of caveat emptor applies to tax sales, so the holder of a void tax title is without substantive rights in the premises except as such rights arise by statute. However, when the owner of the property seeks relief in equity against the void-title holder, the court “may and should require such owner to do equity as a condition” — and the overwhelming weight of authority limits that reimbursement to an amount not exceeding the delinquent tax plus interest.
Reasoning
- Void title confers only what statute gives. Because a void tax title passes no substantive interest, the purchaser cannot demand the full delinquent-tax burden or the resale price as the price of letting the owner reclaim; the purchaser’s protection is purely equitable and statutory.
- Do equity to get equity. A former owner asking a court of equity to clear the void title must reimburse the purchaser’s outlay — but the chancellor caps the condition at the delinquent tax plus interest, preventing the purchaser from using a void title to extract more than the taxes that supported the sale.
Practical impact
- For former owners: Where a South Dakota tax title is void, an owner seeking to set it aside need only reimburse the purchase price / delinquent tax plus statutory interest as a do-equity condition — not the property’s full value or an inflated resale figure.
- For investors / operators: A void tax title is a lien-like equitable claim for reimbursement, not ownership. Buying at a county resale does not cure an underlying void title; the holder’s recovery is limited to taxes-plus-interest if the former owner sues in equity. A core title-and-marketability and quiet-title-after-tax-sale caution in South Dakota.
Good-law status
Still good law as a statement of the void-title / do-equity rule; not overruled
as of last_verified 2026-06-02. (Note: the case predates and is independent of the
modern surplus-takings doctrine in tyler-v-hennepin-county.)
Why it matters
It fixes the remedy for a void South Dakota tax title: the purchaser holds only an equitable reimbursement claim capped at delinquent tax plus interest, and the owner reclaims the land on a do-equity condition.
