## Facts

- Reliance Standard Life Insurance Company agreed on August 4, 1965 to sell Philadelphia property to Anthony and Viola DiDonato for $16,000.
- At contract formation, the property was understood to permit industrial use.
- A zoning ordinance adopted September 22, 1965 reclassified the property from industrial to residential.
- Settlement occurred October 7, 1965, after the ordinance’s adoption but before the change appeared in public records.
- At settlement, an incorrect zoning certification indicated the property remained industrial; both parties relied on it.
- In 1967, when the DiDonatos attempted to resell, they learned the property was zoned residential.
- The DiDonatos filed an equity action seeking rescission, alleging misrepresentation and/or mistake regarding zoning.

## Issues

1. Whether, absent an express contractual term, the purchaser or the vendor bears the risk of a zoning change occurring after execution of a land sale contract but before settlement.
2. Whether an incorrect zoning certification and the parties’ shared misunderstanding about zoning at settlement supports rescission for misrepresentation or mutual mistake.

## Decision

- The Supreme Court of Pennsylvania affirmed the decree denying rescission and entered judgment for the seller.
- The court held the purchaser bears the risk of rezoning occurring between contract execution and settlement unless the contract provides otherwise.
- The court rejected rescission based on the incorrect zoning certification where both parties relied on it and the seller did not intentionally misstate zoning status.

## Legal Principles

- Under equitable conversion, a valid, enforceable land sale contract transfers equitable ownership to the purchaser at contract execution; the seller retains legal title as security for payment.
- Absent an agreement reallocating risk, the purchaser bears losses or detriments affecting the property between contract and closing, including changes in legal permissibility of use.
- A shared mistake tied to a risk allocated to the purchaser by default doctrine does not, without more, justify rescission against a non-culpable seller.
- Parties may shift the risk of regulatory or zoning changes by express contract terms; otherwise the default allocation governs.

## Conclusion

The court denied equitable rescission and held that, because equitable conversion makes the buyer the equitable owner at contract execution, the buyer bears the risk of a zoning change occurring before settlement when the contract does not expressly place that risk on the seller, even if both parties relied on an erroneous zoning certificate.
