Once partnership talks mature, someone says "let's just sign an MOU first." There's a perception that it's a low-stakes document, but in practice an MOU can end up blocking negotiations with another company or lead to talk of damages.
The bottom line
An MOU is generally regarded as having no legal force, but it's the content, not the title, that determines enforceability. Korea's Supreme Court also takes the position that it looks at the substance regardless of what the document is called, so if a document titled "MOU" spells out specific obligations, it can become binding like a contract (Sugar Square). That's why the key to signing an MOU is to clearly separate the clauses you want to be binding from the ones you don't.
MOU vs contract: what's the difference?
| MOU (memorandum of understanding / cooperation agreement) | Contract | |
|---|---|---|
| Purpose | Confirm the direction of cooperation and mutual intent | Fix specific rights and obligations |
| Level of detail | Centered on direction, scope, and schedule | Specific terms such as payment, duration, and liability |
| Enforceability | None in principle, but can arise depending on content | Yes |
| On breach | Claiming damages is usually difficult | Damages, rescission, and other claims available |
An MOU is usually a document for confirming each side's intent at the stage before the main contract, with the detailed terms set through later negotiation (Bridgecode).
Clauses that tend to become binding
Putting the public commentary together, the following clauses are likely to be enforceable even inside an MOU.
- Confidentiality: In most cases it's regarded as binding (Bridgecode).
- Exclusive negotiation: If you've agreed not to negotiate with other companies for a set period, it can actually tie up your company's other negotiations.
- Revenue-sharing ratios, damages, deadlines for signing the main contract: Specific numbers and deadlines increase the chance it's viewed as a contract (Sugar Square).
Conversely, content that only sets direction, such as the scope of information exchange or the direction and schedule of future negotiations, is usually left non-binding.
Checklist before signing an MOU
- The scope of enforceability is stated explicitly, e.g., "This MOU is not legally binding except for Article X (Confidentiality)"
- The duration and scope of the confidentiality clause are written down
- If there's an exclusive negotiation clause, its duration and scope don't tie up our business excessively
- Wording that could be read as an obligation to sign the main contract ("shall," deadlines) matches our intent
- The MOU's term and grounds for termination are written down
- The legal team has reviewed it
Why MOUs should be managed like contracts
Because MOUs "aren't binding," they easily fall outside the scope of what gets managed. But confidentiality obligations and exclusive negotiation periods can survive after the MOU ends, and a few years later you'll find yourself needing to check "did that MOU with that company have an exclusivity clause?" Put MOUs on your contract register alongside everything else, with separate columns for the confidentiality and exclusivity periods. The template is laid out in Contract register Excel template.
If your company has a lot of contracts, a contract lifecycle management (CLM) system that groups the MOU, main contract, and NDA under the same counterparty and keeps a history helps. Based on public materials, PRIX offers contract history tracking and renewal reminders (VentureSquare).
Alpaca's takeaway
An MOU isn't a light document; it's a document that's "easy to make light of." If you separate the binding clauses from the non-binding ones in a single line before signing, you'll greatly reduce what there is to argue about later.
