Deed of Accession

When you need one

• A new shareholder or investor joins a company with an existing shareholders' agreement — on a new issue of shares, a share transfer, or an option or ESOP exercise.
• A new party joins a joint venture governed by an existing JV agreement.
• An incoming partner joins a partnership under an existing partnership deed.
• A new group entity joins an intercompany, facility or security arrangement.
• A new supplier or contractor joins a framework or panel agreement already on foot.

Well-drafted agreements make this automatic: the transfer and issue clauses prohibit the company from registering a transfer or issuing shares until the incoming holder has executed an accession deed in the form of the schedule. If your shareholders' agreement lacks that mechanism, it should be added at the next amendment.

Accession vs novation vs assignment

• Accession — adds a new party. Nobody is released. The original agreement continues unchanged.
• Novation — substitutes a new party for an existing one, transferring both rights and obligations and releasing the outgoing party. Requires all parties' consent.
• Assignment — transfers rights only. Obligations stay with the assignor unless the counterparty agrees otherwise, which is why an assignment alone rarely achieves a clean exit.

If somebody is leaving, accession is the wrong instrument. If somebody is joining and everyone else stays, it is exactly the right one.

What the deed should contain

1. Identification of the principal agreement — full name, date, parties, and any amendments or prior accessions.
2. The covenant to be bound — the new party agrees to observe and perform the agreement as if it had been an original party, in a stated capacity (for example, as a Shareholder).
3. Acknowledgement by the existing parties — often given in advance through a power in the principal agreement, so a fresh signature round is not required.
4. Representations from the incoming party — capacity, authority, and no conflicting obligations.
5. Notice details — address and email for service, so the notices clause works.
6. Governing law and jurisdiction — matching the principal agreement.
7. Execution as a deed — with signing blocks matched to the entity type.

Execution traps

Because it is a deed, execution formalities matter. Companies should execute in accordance with s 127 of the Corporations Act 2001 (Cth). Individuals require the correct witnessing or a valid electronic execution pathway under the applicable state legislation. Trustees should sign in their capacity as trustee for the named trust, and the deed should identify the trust so the party bound is the right one. Getting the signing block wrong on a deed is a surprisingly common reason these documents get re-executed at the worst possible moment — in due diligence, on a sale.
