Legal Risks in SaaS Acquisitions That Most Buyers Miss
From IP ownership gaps to GDPR compliance, the legal issues that surface in our reports and how to address them before closing.
By AcquiCheck Research
Legal due diligence is often the last thing buyers think about in micro-SaaS deals. The amounts feel too small to justify hiring a lawyer. But legal issues are the ones that can surprise you months after closing, and they're often the hardest to fix retroactively.
IP ownership: the silent risk. The most common legal issue we find: code written by contractors without proper IP assignment. If a freelancer wrote 30% of your codebase and there's no work-for-hire agreement or IP assignment, they technically still own that code. In practice, this rarely becomes a problem. In theory, it could block a future sale or create liability.
Open source license compliance. Most SaaS products use open source libraries. That's fine, but some licenses have requirements that surprise people. GPL-licensed code in your product may require you to open source your own code. AGPL is even stricter for SaaS specifically. Always run a license audit.
Privacy compliance. GDPR, CCPA, and their equivalents affect any SaaS with users in Europe or California (which is most SaaS). Common violations we find: no data processing agreements with subprocessors, privacy policies that don't accurately describe data practices, no mechanism for data subject access requests, cookies being set before consent.
Terms of Service gaps. Many micro-SaaS products have ToS copied from a template and never updated. Key issues: limitation of liability clauses that don't cover the actual product, no clear data ownership terms, unclear refund/cancellation policies, missing arbitration or dispute resolution clauses.
Regulatory considerations by vertical. SaaS products in certain verticals have additional compliance requirements. Healthcare (HIPAA), education (FERPA/COPPA), finance (SOC 2, PCI if handling payments). If the seller claims compliance, verify it. If they don't claim it but serve these verticals, that's a risk.
What to do about legal risks. For deals under $100K, a full legal review often isn't cost-effective. Instead, focus on: verifying IP ownership for all code contributors, running an automated license scan, checking privacy policy accuracy, and ensuring the ToS covers your planned operations. Most issues can be fixed post-acquisition at reasonable cost. The key is knowing about them before you set your price.
How we handle it. AcquiCheck's legal risk module checks privacy compliance, license conflicts, ToS coverage, and IP indicators. We flag issues by severity and provide specific recommendations. For deals where we find significant legal risk, we recommend consulting a technology lawyer before closing.
