Source code escrow appears in enterprise software agreements with remarkable frequency given how rarely it provides the protection it's supposed to provide. Gurpreet S. Bal reviews escrow provisions regularly in the context of software licensing and M&A diligence, and the pattern is consistent: the demand is reflexive, the documentation is incomplete, and the release conditions would rarely trigger in the scenarios companies actually fear. "Escrow gets demanded as a checkbox in enterprise procurement without anyone stopping to ask whether the release conditions would ever actually be triggered in the scenarios they're worried about," he says.
Bal advises on technology licensing transactions where escrow provisions are part of the commercial negotiation, and on M&A transactions where the adequacy of existing escrow arrangements is a diligence question.
A source code escrow agreement involves three parties: the software developer (the depositor), the licensee (the beneficiary), and a neutral escrow agent — typically a specialist firm like Iron Mountain or EscrowTech. The developer deposits the source code, build instructions, and related materials with the escrow agent. The escrow agent holds the materials under agreed terms and releases them to the beneficiary only upon the occurrence of defined release conditions. The licensee pays annual maintenance fees to the escrow agent for this service. The critical insight is that escrow does not give the licensee the right to use the source code — it gives the licensee access to the source code if and when a release condition is met, at which point the licensee has whatever license rights are defined in the escrow agreement. If those license rights are narrow — use only to maintain the existing deployment, no right to modify for new functionality — the escrow may provide very limited operational relief.
The standard release conditions in escrow agreements cover scenarios like developer insolvency, cessation of business, or material failure to support the software. These conditions sound comprehensive but are more limited in practice. Insolvency triggers typically require a formal bankruptcy filing or an assignment for the benefit of creditors — a financially distressed vendor that continues operating, even in zombie mode, may not meet the technical definition of the trigger. "Cessation of business" is equally ambiguous: a vendor that sells its assets to an acquirer and is formally dissolved has ceased business, but the successor may be obligated to honor the software license. Material failure to support provisions require a determination of materiality and often a dispute resolution process before the escrow agent will release. The scenarios licensees most fear — the vendor pivots, raises prices dramatically, or gets acquired by a competitor — are typically not release conditions at all.
An escrow deposit is only as useful as what was deposited. The standard deposit obligation requires the developer to provide "source code and related materials sufficient to compile and maintain the software." In practice, deposits frequently contain incomplete code, missing dependencies, outdated versions, or build instructions that reference toolchains and environments that no longer exist. Escrow agents offer verification services — ranging from basic verification that the deposit is readable media, to functional verification that the deposit can actually be compiled into a working product — but many agreements call only for basic verification, which catches nothing about completeness or currency. A beneficiary that receives an escrow release and discovers the deposit is outdated by three versions or missing critical components has received access to something that doesn't actually solve the problem. Verification obligations should be specified contractually, and the verification scope should match the complexity of the software being escrowed.
Even a properly constituted initial deposit becomes stale as the software evolves. A developer releasing quarterly updates to its product has, over two years, produced eight significant versions — and the escrow deposit may reflect the state of the product at initial signing unless the agreement includes enforceable update obligations. Standard update provisions require the developer to deposit updated materials on a defined schedule (quarterly, at each major release, or at each minor version) and certify the deposit's accuracy. Enforcement of update obligations is weak in practice. The beneficiary typically has no visibility into what's in the deposit until a release event, and by then it's too late to address a gap. The practical solution is to include an audit right that allows the beneficiary to request verification of deposit currency and completeness at defined intervals, rather than discovering the problem after a release trigger.
Traditional source code escrow was designed for on-premise software where the licensee could, in theory, run the software independently if it obtained the source code. That model doesn't translate cleanly to SaaS. A cloud-delivered application doesn't run on the licensee's infrastructure — it runs on the vendor's (or the vendor's cloud provider's). Even if a SaaS escrow releases the source code, the beneficiary must now stand up the application infrastructure, migrate its data, configure integrations, and operate a system it has never managed, in the middle of the crisis that triggered the release. SaaS escrow providers offer services designed to address this — depositing not just code but infrastructure configuration, deployment scripts, and data export procedures — but the complexity is substantially higher and the cost reflects that. For most mid-market SaaS buyers, the more effective continuity protection is a combination of: robust data portability rights, contractual notification obligations, and a documented migration plan rather than an escrow structure.
For software that truly needs continuity protection — critical infrastructure, financial systems, mission-critical enterprise applications — the alternatives to traditional escrow deserve evaluation alongside it. Multi-cloud or multi-region deployment obligations can reduce single-vendor risk directly. Source code access rights tied to a defined maintenance failure — without the three-party structure — can be negotiated directly in the license agreement. Open source or source-available licensing for specific components can provide direct access without escrow mechanics. Contractual step-in rights, allowing a designated third party to access the vendor's systems during a defined crisis period, address the SaaS use case more directly than a code deposit. None of these is universally superior to escrow, but each addresses specific failure scenarios more directly. The starting point should be: what failure scenario am I actually trying to protect against, and what mechanism actually addresses that scenario?
