Subsequent Purchaser Warranty Dispute
Santiago Sanchez purchased a newly built home from its first owner. Defects in construction later appeared. When Santiago sued the builder directly, the court examined whether the implied warranty of habitability could be enforced without privity, revealing how authority splits on extending protection to remote buyers.
Mortgage and Note Separation
Sophia Singh originated a mortgage loan and later transferred only the note to a secondary-market buyer while retaining the mortgage document. The transferee sought to foreclose. The court held that the split left the note unsecured and denied enforcement until the mortgage interest was also conveyed.

Burden Allocation in Defense

Common questions
Frequently Asked
4
What happens when a mortgage and the underlying note are split?+
The note becomes unsecured as a practical matter. Enforcement of the mortgage is barred until the interests are reunited because separating the rights produces an economically wasteful result and an unwarranted windfall to the mortgagor.
Does a stock split require shareholder approval when only one class of shares is outstanding?+
No. Under the Model Business Corporation Act a board may amend the articles to triple each issued and unissued share of the single outstanding class without shareholder approval because the change is proportional and creates no class-based conflict.
How does a court decide whether a writing is integrated for parol-evidence purposes?+
The court examines the completeness and specificity of the document itself. A ten-page insurance policy that sets out coverages, exclusions, limits, and deductibles is presumptively integrated, so prior oral assurances contradicting its terms are excluded.
When may a buyer accept some commercial units and reject others in a single shipment?+
A buyer may accept conforming commercial units and reject nonconforming ones when the tender fails in any respect to conform. Each color batch of headphones constituted a separate commercial unit, allowing partial acceptance and rejection.
