Notice of Exercise of Option to Purchase Template

In plain language: Opens the letter with today's date and identifies the option holder (sender) and the seller (recipient) by full legal name and address.

Common mistake: Using a trade name instead of the seller's legal entity name. If the option agreement names the legal entity, the notice must match exactly or the seller can claim it was sent to the wrong party.

In plain language: Cites the governing option agreement by its execution date and a brief description of the subject asset, linking the notice to the specific contractual right being exercised.

Common mistake: Omitting the agreement date or citing the wrong date. A mismatch between the notice and the agreement on record creates a dispute about which right is being exercised.

In plain language: The operative sentence — a clear, unambiguous statement that the option holder is exercising the purchase option in full.

Common mistake: Using hedged language such as 'intends to exercise' or 'is considering exercising.' Conditional or tentative wording may not constitute valid exercise under the option agreement's notice requirements.

In plain language: States the purchase price as defined in the option agreement, confirming the buyer's acceptance of the agreed terms and preventing later price disputes.

Common mistake: Restating a price that differs from the option agreement — even a typographical error can create a dispute about the agreed purchase price and delay or void closing.

In plain language: Briefly confirms that the notice is being delivered within the required notice period and by the method specified in the agreement (e.g., registered mail, email, hand delivery).

Common mistake: Delivering by a method not authorized in the agreement (e.g., email only when registered mail is required). An unauthorized delivery method may render the notice ineffective even if it arrives on time.

In plain language: Requests that the seller confirm closing arrangements and proposes a target closing date consistent with the agreement's timeline.

Common mistake: Proposing a closing date that falls outside the period permitted under the agreement, which can give the seller grounds to object or renegotiate terms.

In plain language: Asks the seller to acknowledge receipt of the notice and confirm that the transaction will proceed on the agreed terms.

Common mistake: Setting an unreasonably short response deadline that the seller cannot meet, creating unnecessary friction at the start of the closing process.

In plain language: Closes the letter with the option holder's printed name, title, entity name, and signature line — creating the evidentiary record that the notice was authorized and sent.

Common mistake: Signing as an individual when the option was granted to a corporate entity — or vice versa. The signatory must match the option holder identified in the agreement, or the notice may be challenged as unauthorized.

A notice of exercise of option to purchase is a formal written letter an option holder sends to a seller to invoke a contractual right to buy an asset at a previously agreed price. It converts the option — a right, not an obligation — into a binding commitment to proceed with the purchase on the terms set out in the underlying option agreement. Without a valid written notice, the option typically lapses at the end of the option period.

The option agreement defines both the option period (the window during which you may exercise) and the required notice period (how many days before expiry notice must be delivered). You must send the notice so that it is delivered — not merely sent — within both windows. Most agreements contain a time-is-of-the-essence clause, meaning a late notice forfeits the right entirely. Build in at least 5–10 business days of lead time to account for postal delivery and confirmation.

While the letter template includes a signature block as a best practice, the signature requirement depends on the underlying option agreement's notice provisions. Many agreements accept an authorized signature on a written notice; some require a notarized signature. Review your option agreement's notices clause before dispatching and add a notarized signature block if required.

Once a valid notice is delivered, the seller is contractually bound to proceed with the sale on the agreed terms. The parties then work toward a closing date — transferring title, paying the purchase price, and exchanging all required documents. If the seller refuses to proceed after a valid notice, the option holder typically has grounds for specific performance or damages in court.

If the notice is validly delivered within the option period and by the required method, the seller generally cannot refuse without breaching the option agreement. The option holder may seek a court order for specific performance — compelling the seller to complete the transaction — or claim monetary damages. Consulting a lawyer before taking further action is advisable if the seller does not cooperate.

An option to purchase grants the holder the right to buy at a fixed price within a set period, regardless of whether the seller wants to sell. A right of first refusal only activates when the seller decides to sell to a third party — the holder can then match that offer. Options require a proactive notice of exercise; rights of first refusal require notice from the seller first.

For straightforward transactions where the option agreement is clear about notice requirements, price, and deadline, a well-completed template is typically sufficient. Engaging a lawyer is advisable when the asset value is significant, when the notice requirements are complex or ambiguous, when the seller has indicated potential resistance, or when the transaction involves real estate in a jurisdiction with specific statutory notice rules.

Retain a dated copy of the signed letter, proof of delivery (registered mail receipt, courier confirmation, or email read receipt), and any written acknowledgment from the seller. These records establish that notice was validly given within the option period if the transaction is later disputed.
