A New York Notice of Assignment by Seller to Holder of Preferential Purchase Right is a legal document used to inform a purchaser's right holder about the assignment of a property purchase contract. This notice provides important information regarding the transfer of the seller's contractual rights to another party, allowing the assignee to step into the seller's shoes and complete the purchase transaction. In New York, there are two types of Notice of Assignment by Seller to Holder of Preferential Purchase Right documents: 1. Voluntary Assignment: This type of notice is filed when the seller willingly transfers their rights and obligations under the purchase agreement to the assignee. It ensures transparency and notifies the holder of the preferential purchase right that the seller has opted to assign the contract to a third party. 2. Involuntary Assignment: If the original purchaser fails to fulfill their obligations under the purchase agreement, such as defaulting on payments or breaching the contract's terms, the seller may have the right to assign the contract to another party. This involuntary assignment notifies the holder of the preferential purchase right about the transfer and allows the new assignee to take over the purchase process.
