The New Hampshire Securities Deposit Agreement is a legal document that is used to record the transfer of a security deposit from a seller to a buyer. This document is used to protect the buyer in the event that the seller fails to fulfill the contractual obligations under the agreement. The agreement outlines the specifics of the security deposit, such as the amount, date, and purpose of the deposit, as well as the buyer's rights and obligations with respect to the security deposit. There are three main types of New Hampshire Securities Deposit Agreement: an irrevocable security deposit agreement, a revocable security deposit agreement, and a collateral security deposit agreement. An irrevocable security deposit agreement is a binding agreement that cannot be amended or revoked until the terms of the agreement are met. A revocable security deposit agreement allows for the agreement to be amended or revoked at any time prior to the terms of the agreement being fulfilled. A collateral security deposit agreement requires the buyer to post a security deposit to secure the seller's performance under the agreement. These deposits are typically held in escrow until the terms of the agreement are met.
