How to Draft a Deed of Adherence (2026 Template and Clauses)

A deed of adherence is a short legal document by which a new party agrees to be bound by an existing agreement, most often a shareholders' agreement, as if it had been an original party to it. It is the standard way to bring a new shareholder, investor or joint-venture participant inside an agreement they did not originally sign. This guide explains what a deed of adherence does, the clauses it needs, and gives a skeleton you can adapt. It is written for founders, company secretaries and anyone managing a cap table. It is general guidance, not legal advice. ## What a deed of adherence does Shareholders' agreements, investment agreements and joint-venture agreements bind only the people who signed them. When new shares are issued or existing shares are transferred, the new holder is not automatically bound by that agreement. A deed of adherence fixes this: the incoming party signs it, and from then on they have the same rights and obligations under the main agreement as the existing parties. Most well-drafted shareholders' agreements make this compulsory. They include a clause saying no share can be issued or transferred to a new holder until that holder has signed a deed of adherence, and often attach the form as a schedule. This keeps everyone on the cap table inside the same set of rules. Why it matters: - It protects the existing parties. Pre-emption rights, transfer restrictions, drag and tag rights and confidentiality only work if every holder is bound.

• It keeps the agreement whole. Without it, a share transfer could create a holder with no obligations, undermining the whole arrangement.
• It is quick. Rather than re-signing the whole agreement, the new party signs one short deed. ## Why a deed, and not just an agreement It is usually executed as a deed rather than a simple contract. A deed removes any argument that the new party gave nothing in return for taking on the obligations (the consideration point), and it is the form the main agreement typically requires. Execution formalities for a deed, such as signature in the presence of a witness, depend on the jurisdiction and the type of party, so follow the rules that apply where the company and the signatory sit. ## The core structure of a deed of adherence A deed of adherence is deliberately short. It does not repeat the main agreement; it adopts it. ### 1. Title and date State that it is a deed of adherence and the date it is made. ### 2. Parties Name the new party (the adhering party) and, usually, the company and sometimes the existing shareholders or their representative. Many forms have the new party covenant directly with the existing parties. ### 3. Recitals Identify the principal agreement by name and date, for example the shareholders' agreement dated a given date, and state that shares have been or are about to be issued or transferred to the new party, who is required to adhere. ### 4. Definitions Usually just adopt the definitions in the principal agreement by reference, so the same defined terms carry across. ### 5. The covenant to be bound The operative clause: the new party covenants with the existing parties (and the company) to observe and perform the principal agreement, and to be bound by it, as if it were an original party and named in it, with effect from the date of the deed or the share transfer. ### 6. Benefit of the agreement State that the new party is also entitled to the benefit of the principal agreement, so the obligation runs both ways, they take the rights as well as the duties. ### 7. Capacity and class If there are different classes of party (for example founders, investors, employees) say which capacity the new party adheres in, because rights and obligations often differ by class. ### 8. Notices and governing law Give the new party's notice details for the principal agreement, and confirm the governing law and jurisdiction, usually matching the principal agreement. ### 9. Execution as a deed An execution block appropriate to a deed for the type of signatory. ## A usable deed of adherence skeleton ```

1. Title: Deed of Adherence; date
2. Parties (new party; company; existing parties or representative)
3. Recitals (name and date of principal agreement; the share event)
4. Definitions adopted from the principal agreement
5. Covenant to be bound as if an original party
6. Entitlement to the benefit of the principal agreement
7. Capacity or class in which the party adheres
8. Notice details; governing law and jurisdiction
9. Executed as a deed

- **Wrong capacity.** Adhering a new investor as if they were a founder, or the reverse, pulls in the wrong rights and obligations. State the class clearly.
- **No effective date.** Say exactly when the new party becomes bound, usually on the transfer or allotment.
- **Not executed as a deed.** If the principal agreement requires a deed, a simple signed agreement may not satisfy it. Follow the required form and execution formalities.
- **Form not kept current.** If the shareholders' agreement has been amended, the deed should adhere to the agreement as amended. Reference the current version. ## Drafting, reviewing and tracking adherence in one place A deed of adherence is small but it is tightly tied to a larger document and to a cap-table event. It must name the right principal agreement, use its current defined terms and bring the new party in under the correct class. When the shareholders' agreement, the cap table and the deeds live in separate places, it is easy to adhere someone to a stale version or in the wrong capacity. Keeping the deed, the review and the underlying agreement in one workspace avoids that drift. [Adira](https://adiralaw.com) is one such workspace, built on frontier AI, where you can draft the deed from a brief tied to the current shareholders' agreement, see each clause marked favourable, neutral or unfavourable to the company or the existing holders, link the deed to the principal agreement and the share event, and keep the signed deeds attached to the cap-table file rather than loose in an inbox. The deed and the agreement it joins stay connected. A deed of adherence is only doing its job if it binds the new party to the right agreement, in the right capacity, with both the rights and the obligations.
