Practice point:  New York law favor the free and unobstructed use of realty. A purchaser takes with notice from the record only 
of incumbrances in the direct chain of title. Absent actual 
notice before or at the time of the purchase, a land owner is bound only by such restrictions as appear in some deed of record in the conveyance to the owner or a direct
 predecessors in title. A purchaser is not required to search outside the chain of title.
Student  note:  Deed restrictions are strictly construed against those seeking
 to enforce them and will be enforced only on the basis of clear and convincing proof.
Case:  Butler v. Mathisson, NY Slip Op 01289 (2d Dept. 2014).
