What Are the Options? Call Option Agreements: Key Terms and Legal Considerations for Businesses

Thinking about ways to structure your business deals, bring on investors, or plan for future company changes? You might have heard people talk about “options,” and wondered, what are the options really available to you? One term that’s becoming more popular in the UK business world is a “call option agreement.”

If you’re unsure what this means, don’t stress - you’re not alone. Many founders, shareholders, and business owners want flexible ways to buy or sell shares, assets, or interests in their company, but worry about getting the legal side right.

In this guide, we’ll break down exactly what call option agreements are, the benefits they offer, and what legal points you’ll need to cover to stay protected. We’ll also explore broader “option” strategies in business contracts, and where professional legal advice can make a real difference. Keep reading to find out everything you need to know about call options and how to use them confidently in your business deals.

What Are the Options in Business? Understanding Options in a Nutshell

When people talk about “options” in business, they’re usually referring to special rights (but not obligations) to make a certain decision in the future. The most common places you’ll see options in business are:

• Call options: The right to buy something (usually shares or business assets) at a later time for a fixed price or a price determined by a formula
• Put options: The right to sell something to another party on specific terms
• Share options: Used to reward founders, employees, or investors by giving them the future right to buy shares in the business

Options are all about flexibility and future planning. They let you “lock in” potential deals (like share buybacks, exits, future fundraising, or partner transitions) in a way that’s clear and legally binding before anything changes hands.

If you’re looking at ways to incentivise staff or attract investors, share options and company share schemes are another area to consider. For more on those, check out our complete guide to share option schemes in the UK.

What Is a Call Option Agreement?

A call option agreement is a legal contract that gives one party (often a buyer or investor) the right, but not the obligation, to purchase specific assets or shares of a business at a set time in the future, and for an agreed price or at a formula determined in advance. The other party (the “grantor”) is required to sell if the option is exercised.

In plain English: a call option is a way to secure your “first dibs” on a deal, without making a commitment to buy straight away. It’s widely used in the UK for:

• Startup funding rounds (so investors can buy more shares later if things go well)
• Succession planning in family businesses, founder “buyouts,” or partnerships
• Securing assets in mergers, acquisitions, or company restructuring
• Planning property or franchise deals (such as securing the right to purchase a site or business when certain conditions are met)

The call option agreement will set out exactly how and when the right can be used, the price or pricing method, and what happens if things change before the option is exercised.

Why Use Call Option Agreements? Key Benefits for Businesses

Options aren’t just technical legal tools - they offer real flexibility and risk management for business owners. Here’s why a call option agreement might make sense in your situation:

• Flexibility and Planning: Gives you or your investors time to check due diligence, secure funding, or see how things develop before you commit to buy.
• Reducing Risk: Protects your position by locking in terms up front, rather than facing a renegotiation later.
• Encouraging Growth: Can help attract investors by offering them a simple way to increase their stake in successful companies in future rounds.
• Simplifying Transitions: Makes share transfers, exits, or restructures much smoother for partnerships or family businesses.
• Securing Strategic Assets: Useful in M&A deals to secure the right to buy a specific department, brand, or property as circumstances change.

Of course, options aren’t right for every deal. You’ll want to weigh up the practical benefits against the complexity - which is why it’s important to understand the key legal considerations below.

What Key Terms Should a Call Option Agreement Cover?

So, you’re thinking about putting a call option in place - but what actually needs to be in the agreement? Here are the key terms you’ll want to include (and discuss with your legal adviser):

• The Option Instrument: Make it clear what specific right is being granted (e.g. the right to buy a set number of company shares, or a specific business asset).
• Option Period: Define the exact dates or events when the option may be exercised (e.g. a 12 or 24 month window, or on a certain “trigger” like a funding event or a target being achieved).
• Option Price: Set the price or pricing formula. This could be a fixed amount, a valuation formula, or tied to independent appraisal.
• Notice Requirements: Detail exactly how the option is exercised (written notice, method of communication, etc) and what information must be included.
• Exercise Conditions: If there are pre-conditions for using the option (such as regulatory approval, financing, or business performance criteria), state them clearly.
• Obligations Upon Exercise: Specify what each party must do once the option is exercised - such as transferring shares, paying the price, or updating Companies House.
• Consequences of Non-Performance: Set out penalties or remedies if one party can’t deliver on their obligations.
• Other legal clauses: This includes dispute resolution (arbitration or courts), governing law (usually English law for UK deals), confidentiality, assignment rights, and any warranties about the asset or shares in question.

As you can see, the details really matter. Avoid using generic templates or drafting them yourself - legal documents need to be tailored to your specific needs and risks.

How Is a Call Option Different from a Share Option or Put Option?

It’s easy to get confused by all the “option” lingo. Here’s a quick explainer of the main differences you might encounter:

• Call Option: Right to buy an asset or shares in the future.
• Put Option: Right to sell an asset or shares to someone else at a future date.
• Share Option (or Share Scheme): Usually gives employees or founders the right to buy shares as an incentive - sometimes with special tax advantages.

While call options and share options sound similar, share option schemes are usually part of staff incentive plans, not company buyout or investment deals. If you’re planning for equity reward, head over to our EMI share scheme guide for the full legal and tax rundown.

What Legal Risks Should I Watch Out For With Call Option Agreements?

Options can be incredibly useful - but if they’re not drafted carefully, you might run into problems later. Here are the most common legal risks:

• Ambiguity: If the agreement isn’t crystal clear on price, timing, or the process for exercising the option, you could end up in a dispute.
• Competition Law: Option deals between competitors may breach UK competition law in some circumstances.
• Company Rules: Your company articles of association or shareholder agreement may restrict or complicate share transfers, so always check first.
• Regulatory Approvals: Some assets or large shareholdings may require approval from the FCA or other regulators before a transfer.
• Tax Implications: Exercising options can trigger tax events - especially with shares. Make sure to get professional advice on company taxation and capital gains.
• Misuse or Unenforceability: If the agreement isn’t properly signed, dated, or witnessed (where required), it might not be legally binding.
• Failure to Document: Verbal agreements or emails won’t protect your rights in the same way as a properly drafted contract.

If you get these wrong, you could find yourself in a position where you can’t enforce the option - or worse, end up in a costly business dispute. Setting up your legal foundations early, and keeping them updated, will give you maximum peace of mind.

Do I Need a Lawyer to Draft or Review a Call Option Agreement?

It’s easy to underestimate how complex “simple” option agreements can get. Templates often leave out important protections or fail to address real-world scenarios (like what to do if the parties disagree about a valuation, or if the business changes hands before the option period ends).

Why should you consider proper legal advice for your call option agreement?

• Tailored to your business: A lawyer will draft your call option so it works with your company’s articles, other contracts, and your tax or regulatory requirements.
• Spotting pitfalls: You get advice on risks you might never have considered - like director duties, regulatory issues, or unknown liabilities lurking in the deal.
• Saving time and disputes: A well-drafted agreement keeps everyone on the same page, reducing friction and protecting your business if there’s a disagreement later.
• Full-spectrum support: Getting legal help often comes with advice on related tasks, like trademark protection, updating company registers, or privacy policy compliance.

It’s essential to have professionally drafted agreements every time you’re dealing with company ownership, shareholding, or future asset transfers. If you’re unsure how to get started, here’s what to look for in a legal expert who understands your business goals.

Are There Laws and Regulations You Must Follow for Option Agreements?

Absolutely. Any time you’re setting up an option over shares or business assets in the UK, you’ll need to keep a few key laws in mind:

• Companies Act 2006: Sets the rules on issuing new shares, transfer restrictions, director duties, and board approvals. Your company’s articles of association and shareholders’ agreement often play a big role.
• Competition Law: Prevents certain exclusive dealings between businesses that might reduce market competition.
• Financial Services Rules: For options over certain assets (especially those classed as financial instruments), FCA regulations may apply.
• Tax Law: The exercise of options, especially in employee incentive schemes or share buybacks, can have specific tax consequences.
• Other Contract Law: Basics like offer, acceptance, consideration (payment of an option premium), and intention to create legal relations must be present.

If you’re using options for acquisitions, international ventures, or fundraising, there may be other industry-specific rules as well. It can be overwhelming to know exactly which ones are relevant - so chatting to a legal expert about the risks your business might face is always a smart move.

What’s the Process for Implementing a Call Option? Step-by-Step Guide

Setting up a call option agreement is best done methodically. Here’s the typical process most businesses will follow:

1. Outline Your Goals: What are you hoping to achieve? Is this for investment, an exit plan, succession, or something else? Be clear on the scenario.
2. Check Company Rules: Review your company’s articles, any shareholder agreements, or partnership documents for restrictions or special procedures.
3. Negotiate Key Terms: Discuss with the other party(ies) the price, period, conditions for exercising the option, and how payment will be structured.
4. Get Professional Legal Support: Have a lawyer draft or review your call option agreement, ensuring it fits with your broader business documents and legal requirements.
5. Execute the Agreement: All parties must sign and (if necessary) witness the contract properly. Update your company’s records or registry as needed.
6. Monitor and Manage: Keep track of option deadlines and keep all parties informed of any relevant developments or changes.
7. Exercise (or Not): When the time comes, the holder can choose to exercise the option. If it’s not exercised before expiry, it lapses.
8. Complete the Transaction: If exercised, finalise the transfer of shares or assets, register any necessary changes, and settle payment.

At every step, clear documentation and professional advice will help ensure you’re actually protected - not left exposed if things don’t go as planned.
