- Depositor
- The software licensor who places the source code and related materials into escrow with the trustee.
- Beneficiary
- The licensee who has the right to receive the source code from the trustee if a defined release condition occurs.
- Trustee / Escrow Agent
- The neutral third party that holds the deposited source code and releases it only when contractually specified conditions are met.
- Deposit Materials
- The full set of assets placed in escrow — including source code, build scripts, technical documentation, encryption keys, and third-party library references needed to compile and operate the software.
- Release Condition
- A specific, defined event — such as licensor insolvency, failure to maintain the software, or material license breach — that triggers the trustee to release the deposit materials to the beneficiary.
- Verification
- A technical audit, conducted by the trustee or an appointed expert, confirming that the deposited materials are complete, current, and sufficient to build and operate the licensed program.
- Limited License
- The restricted right granted to the beneficiary to use the released source code solely to maintain or operate the licensed program for their own internal purposes — not to distribute or sublicense.
- Update Obligation
- The depositor's contractual duty to deposit a new version of the source code each time a material update, patch, or new release of the licensed program is issued.
- Escrow Fees
- Charges payable to the trustee for initial setup, annual custody, verification services, and release administration — typically allocated between the parties in the agreement.
- Sole Remedy Clause
- A provision stating that access to the escrowed source code is the beneficiary's exclusive remedy for the triggering failure — limiting the licensor's broader contractual liability.
- Interpleader
- A legal procedure allowing the trustee to deposit the source code with a court when both parties make conflicting release demands, letting the court determine who is entitled to it.
