Buy-sell agreements and purchase agreements, explained

A **buy-sell agreement** is a contract between co-owners that decides what happens to an owner's share on death, disability, divorce, retirement or a dispute. A **purchase agreement** (asset or stock purchase agreement) is the contract you sign when you actually sell the business. Owners planning an exit need both to be in order.

Buy-sell agreement: check these now

  • Triggers: death, disability, divorce, retirement, termination, deadlock.
  • Valuation method: a fixed price signed years ago is almost always wrong; use a formula or an independent appraisal process.
  • Funding: life and disability insurance or an installment schedule the company can afford.
  • Right of first refusal before any owner can sell to an outsider - including a PE platform that approaches one partner.

Purchase agreement: the sections that move money

  • Purchase price and adjustments (working capital, debt, cash).
  • Representations and warranties about your financials, taxes, licenses, employees and contracts.
  • Indemnification: caps, baskets, survival periods - see escrow and holdbacks.
  • Covenants: non-compete and non-solicit (state law varies; see California and Florida).
  • Closing conditions: financing, landlord consent, license approvals.

Frequently asked questions

What is a buy-sell agreement?

A contract among business co-owners that sets when an owner must or may sell their share, how it is valued, and how the purchase is funded.

Is a buy-sell agreement the same as a purchase agreement?

No. The buy-sell governs co-owners before any sale; the purchase agreement is the contract for an actual sale.

Who drafts the purchase agreement?

Usually the buyer’s counsel drafts; your attorney negotiates. Have a deal attorney, not a generalist, review it.
