Documents · before you sellWhat to request before you sell startup shares
A private-share sale rarely fails on price — it fails on paperwork and permissions. Here's what to line up before you start, so a transfer clears cleanly.
Confirm you can actually sell
- Your share certificate / proof of ownership — that the shares are vested, exercised and genuinely yours.
- The ROFR and transfer-restriction clauses — who gets first refusal and what notice is required.
- Any board-approval requirement — most private transfers need the company's sign-off.
- The shareholders' agreement (especially in Europe) — drag/tag, pre-emption and permitted-transferee rules.
Line up the sale paperwork
- A recent valuation reference — the 409A and any last-round price, to sanity-check an offer. See what discount is fair.
- The company's transfer process / forms — many have a set procedure; ask early.
- Tax records — your strike, exercise date and cost basis, for the capital-gains calculation.
