Buy-Sell / Share Transfer Agreement

Buy-Sell / Share Transfer Agreement: a practical guide

A Buy-Sell / Share Transfer Agreement records how shares in a company will be sold or transferred between parties. It can document a specific transfer or set out what the parties plan to do if a future event prompts a buyout.

What it's for

Use this document when one or more owners plan to sell or transfer some or all of their shares, or when owners want to agree in advance how a future change in ownership will work. It can set out who is transferring shares, who will receive them, the price or method for setting it, and when the transfer is intended to take place.

The parties should be clear about whether they are documenting a share sale now or setting rules for a possible future buyout. A share transfer concerns ownership of the company; if the parties are buying or selling selected business assets instead, a different type of sale document may fit better. A future buyout arrangement may also need to match the company's existing ownership documents and any prior agreements.

Who uses it

• A shareholder selling some or all of their shares to another existing owner.
• A company founder transferring shares to a new co-owner.
• Owners who want to plan what happens if one of them leaves the business or can no longer take part.
• A buyer and seller who have agreed on a private transfer of company shares.
• A company or group of owners arranging a transfer among several people or company entities.

Terms to decide on

Shares being transferred

Identify the company and state how many shares, what type or class, and what portion of ownership is changing hands. Say clearly whether the transfer covers all of the seller's shares or only some.

Price and payment

State the agreed price or explain how it will be calculated, including any valuation process the parties choose. Describe when and how payment will be made, and what happens if payment is delayed or made in stages.

Transfer date and completion

Set out when the parties intend the transfer to take effect and what steps must happen before completion, such as payment or delivery of transfer documents. If the transaction depends on an event or approval, describe that condition and what happens if it does not occur.

Future buyout events

For a continuing buy-sell arrangement, list the events that may start a buyout, such as an owner's decision to leave or inability to continue. Say who may or must buy the shares and how the process begins.

Transfer rights and approvals

Explain whether shares may be transferred to someone outside the current ownership group and whether the other owners have a first chance to buy them. Check that the agreed process fits existing company documents and any required approvals.

Ownership and voting after transfer

Record the ownership percentages before and after the transaction, and explain whether voting or other owner rights change. Make sure the figures match the number and type of shares being transferred.

Other agreed terms

Use Additional Terms & Provisions to describe transaction details that do not fit elsewhere, such as documents each side will provide, responsibility for transfer costs, or handling a disagreement about the price. Use direct wording that says who must do what and when.

Common mistakes

• Writing only an ownership percentage without identifying how many shares or what type of shares are changing hands. Percentages can be unclear if the company has different share types or changes its total shares.
• Using a capital contribution figure as if it were the price for shares sold by an existing owner. A contribution to the company and payment from a buyer to a seller are different transactions; describe the actual payment arrangement.
• Agreeing on a price without explaining when payment is due or how a future price will be determined. A valuation method that depends on later agreement can leave the parties without a clear next step if they disagree.
• Describing a future buyout but leaving out who can start it, who must buy, or what happens if more than one owner wants to purchase the shares.
• Overlooking existing company documents or promises made to other owners. Conflicting transfer rules can create uncertainty about the steps the parties need to take.
• Assuming signing alone updates the company's ownership records. Transfer paperwork, approvals, notices, witnesses, notarization, registration, or specific wording may be required in some places; check the rules where the document will be used.

Before you sign

• Confirm the exact legal name of the company and compare it with its ownership records.
• Check the number and type of shares, current ownership, and the percentage each party will hold after the transfer.
• Read existing company documents and earlier agreements for transfer restrictions, approval steps, or purchase rights.
• Confirm the price, payment method, timing, and any agreed process for resolving a valuation disagreement.
• Write down every condition to completion and identify who is responsible for each required step or document.
• Check local requirements for share transfers, signatures, witnesses, notarization, notices, registration, and wording, or ask a qualified lawyer if the transaction is significant.
• Make sure every person or company that must sign is correctly identified and that the agreement matches the final deal.
