Gentlemen's agreement

“An informal agreement that relies on the parties' trust and honour rather than a written, legally enforceable contract. Depending on the facts and local law, a court may still treat parts of it as binding.”

Why a gentlemen’s agreement matters to a first-time founder

Relying on trust alone can leave price, ownership, deadlines and remedies uncertain when memories or interests change. An informal promise may still have legal consequences in some jurisdictions. Founders should record important commitments instead of assuming “non-binding” means risk-free.

Examples of gentlemen’s agreements

Two founders verbally agree that one will receive 20% of the company after building the product. Nothing records vesting, timing or what happens if either leaves. Six months later they remember different terms, and fundraising stalls while ownership is disputed.

Common misunderstanding

It is not necessarily an oral contract. The phrase usually suggests an honour-based understanding that the parties do not intend courts to enforce, but intention and enforceability depend on facts and local law. Calling something informal does not settle its legal status.

When to use it

Use the phrase to describe a trust-based understanding, not as a substitute for proper documentation. Put material commercial promises into a clear written agreement and obtain legal advice where ownership, employment, confidentiality or significant money is involved.
