When a buyer accepts a deed, the law usually treats the deed as the last word. Promises made in the purchase contract “merge” into the deed and disappear. But not every promise merges, and knowing which ones survive can be critical. A recent Supreme Court decision shows where the line falls.
Brandaan and Melissa DeGroot purchased real estate and items of personal property from Dave and Adrean Armitage. The 10-acre property and personal property contents sold for $450,000 total.
Two documents were prepared. The first addressed the real property and provided a price of $350,000. The second stated a price of $100,000 for all contents.
The first contract – for the realty – provided that Sellers would convey the personalty by separate agreement, and identified some of the items. The second contract similarly identified a few objects of personal property, then swept in “any and all contents of all buildings” and similar catch-all language.
The second contract – for the contents – cross-referenced the first, stating that the purchase was “conditioned upon completed purchase of [property address].”
The realty was conveyed at closing, and Buyers paid $350,000. However, Buyers failed to pay the $100,000 owing under the personalty contract.
Sellers filed a lawsuit seeking the $100,000 called for by the personal property contract. The trial court ruled in favor of Sellers, awarding $96,538 – the $100,000 price, less a $3,462 offset for items that were missing at closing.
Buyers appealed.
On appeal, Buyers did not contest that the personalty contract required a $100,000 payment to Sellers. Instead, Buyers argued that the merger doctrine bars prior or separate agreements from altering the terms of a final written agreement, and that acceptance of a deed creates a presumption that the deed concludes the transaction.
The trial court had rejected the merger defense, and the Idaho Supreme Court agreed. One of the few exceptions to the merger doctrine applies when there is a collateral or independent agreement that the parties intended to survive delivery of the deed. This exception allows a promise within a real estate contract to survive merger with the deed at closing.
The Court framed it as a two-part test: the exception applies if the promise is (1) collateral, and (2) intended to survive the deed.
A promise within a purchase and sale agreement is “collateral” if it does not relate to title, possession, parcel size, or crops. Here, the promise to pay $100,000 for the contents was collateral: it concerned money, not title or possession of the land. The intent requirement is satisfied if it is clear that the parties expected the provision to continue after delivery of the deed.
As for intent, two separate contracts were drafted to evidence the sale. If the parties had intended the personalty to merge with the real estate, they logically could have used a single contract for both, for total consideration of $450,000. They did not – and the conditional language tying the contents purchase to the completed realty purchase confirmed the $100,000 was meant to be paid, and to remain enforceable, after closing.
Conclusion: the parties intended the personalty contract to survive closing of the realty contract, with the $100,000 for contents to be paid afterward. The collateral promise exception to the merger doctrine applies.
Buyers’ appeal is rejected. Sellers win, again. The practical lesson for drafters: if a promise is meant to outlive the closing, make that intent clear in the documents – here, two separate contracts and the conditional payment language did exactly that.
