Most businesses eventually sit across from a client, supplier or contractor and agree that the arrangement has run its course. There is often no breach, no argument and no letter of demand. The scope has changed, the numbers no longer stack up, or one side is pivoting and the other cannot follow. When that happens, ending the contract by mutual agreement is usually the lowest-risk way to close the file.
Done properly, the process ends with a signed termination deed or agreement that ends future obligations, records the final money position, sorts out handover and releases each side from claims. What it does not do is wipe away everything that happened before. Rights already earned, payments already owing and obligations the contract says survive all keep operating unless the termination document says otherwise. That is the assumption most people get wrong, and it is why the paperwork matters more than the conversation.
What to sort out before you negotiate
Work through these before you put anything to the other party. Each one is a decision you will otherwise be forced to make under pressure at the table.
- The original contract and any amendments: pull out the termination clause, notice periods, payment terms, IP ownership, confidentiality, and dispute resolution provisions. Check whether anything auto-renews, because an automatic renewal term is a common reason a relationship that "ended" quietly keeps billing.
- A decided end date and exit shape: immediate termination, end of month, or a phased handover with work continuing to a set date. The end date drives everything else in the document.
- A reconciled record of work, money and property: deliverables delivered and accepted, work in progress, invoices issued, deposits, credits, set-offs, and equipment or access credentials in each side's hands.
- The list of obligations that must survive: confidentiality, IP licences, indemnities and restraints. These do not survive on their own; they survive only if the contract or the termination document says so.
- Authority to sign: for a company, s 127 of the Corporations Act 2001 (Cth) sets out who can bind it: two directors, a director and the company secretary, or, for a proprietary company with a sole director, that director. If the person signing has no authority, the clean exit can be challenged later.
- A view on releases: what each side is prepared to give up, and what must be carved out so the release does not cost more than the exit saves.
The path to a signed termination document
There is no regulator to notify and no form to lodge. The process is driven by contract law and by how much detail the two sides are prepared to commit to writing. The sequence below follows the order in which the decisions actually need to be made.
Review the original contract for termination rights
Even when both sides want to end the relationship, the original contract sets the starting position. It tells you what is already owed, what happens to work product, whether confidentiality and indemnities survive, and whether mediation is required before anyone goes to court. If it is unclear or silent on a point, that is a reason to be more careful with the termination document, not less, because that document becomes the reference point if anything later goes wrong.
Australian law lets parties discharge or vary a contract by a later agreement. In Tallerman & Co Pty Ltd v Nathan's Merchandise (Vic) Pty Ltd (1957) 98 CLR 93, the High Court confirmed that whether a later agreement between the same parties discharges the earlier contract depends on their intention. That is what a termination document does: it records the intention to end the contract, on terms.
Reconcile the work, money and property
Before anyone drafts a clause, both sides need to agree on what has actually happened. A termination negotiation that starts from different versions of the facts will fail.
- deliverables completed and accepted, and work still in progress
- final invoices, credits, set-offs, deposits and milestone payments
- a walk-away payment if one side is giving up expected future revenue
- equipment, files, stock and access credentials to be returned, and by when
Vague financial terms are the most common reason disputes restart after a "clean" exit. If the numbers are not in the document, they will be argued about later.
Choose between an agreement and a deed
A simple agreement to terminate needs consideration: each side must give something up. A deed does not, which is why deeds of termination are common. The release and the final payment can be enforced without having to show what each side gave in exchange.
Execution differs too. Under s 127 of the Corporations Act 2001 (Cth), a company executes a document or deed by signing with two directors, a director and the company secretary, or the sole director of a proprietary company (who is also the secretary, or where there is no secretary). Electronic signatures are permitted. For individuals and sole traders, the person themselves signs.
Draft the termination document
The document needs to capture the deal, not the sentiment. In practice the clauses that matter are:
- Identification: the contract being terminated, by date and parties, and the effective date
- Survival: which clauses keep operating after termination, including confidentiality, IP ownership, indemnities and restraints
- Money: the final amount, when it is paid, GST treatment, late payment, and whether either side can set off
- Handover: final deliverables, formats, access removal, and return of property
- Releases: a mutual release of claims, with carve-outs for amounts due under the document, fraud or wilful misconduct, and anything else the parties agree must remain actionable
- Public statements: what each side may say about the termination, such as "the parties ended the arrangement by mutual agreement"
- Dispute resolution: a short negotiation or mediation step before either side can sue
Two drafting points deserve emphasis. First, mutual termination ends future obligations but does not by itself divest rights that have already been unconditionally acquired. That principle, stated in McDonald v Dennys Lascelles Ltd (1933) 48 CLR 457 and applied in Flowers v Vescio [2006] NSWCA 342, is why the document must say expressly what happens to amounts already earned. Second, a broad "full and final settlement" release cuts both ways: it can stop the other side suing you, but it can also stop you recovering an overpayment or pursuing defective work you have not discovered yet. Carve-outs are how you keep those rights.
Negotiate, sign and execute properly
Put a short draft in front of the other party early. People negotiate more constructively against a written proposal than against an abstract conversation. Frame the discussion around outcomes: timing, handover and money, rather than who is at fault.
Before signing, confirm who signs for each side and that they have authority. If it is a deed, make sure it is expressed to be a deed and is signed by the people s 127 of the Corporations Act 2001 (Cth) requires. Keep the executed copies on file, because they are the evidence the relationship ended when and how you say it did.
Close out operations and customer-facing steps
The legal document is only part of the exit. The rest is operational:
- issue final invoices and reconcile accounts
- revoke system access and recover equipment
- complete the handover and update customer records
- tell customers what they need to know, without overstating it
That last point carries real legal weight. Section 18 of the Australian Consumer Law (Schedule 2 to the Competition and Consumer Act 2010 (Cth)) prohibits conduct in trade or commerce that is misleading or deceptive or likely to mislead or deceive. What a business tells customers about delivery timeframes, availability or whether a service continues can breach that section, so customer communications about a termination should match the contractual reality.
If the relationship you are ending is with an employee rather than a contractor, stop and reset. Mutual agreement cannot contract a business out of the Fair Work Act 2009 (Cth). The National Employment Standards are minimum standards that cannot be displaced (s 61), and termination still requires written notice or payment in lieu (s 117). Employment exits follow a different process, with different risks.
Where people typically get held up:
- Relying on a friendly email chain: An exchange of emails can evidence an agreement, but it rarely deals with releases, survival, IP or the final numbers. When the relationship later sours, the gaps become the dispute.
- Forgetting survival clauses: The original contract's confidentiality, IP and indemnity clauses may keep operating. If the termination document says nothing about them, you end up with two documents pointing in different directions.
- Signing a broad release without checking the carve-outs: "Full and final settlement" protects you from claims, but it can also give away rights you did not know you had.
- Treating an employment exit like a commercial one: Statutory minimums under the Fair Work Act 2009 (Cth) still apply, whatever the email chain says.
Where a lawyer earns their fee
A commercial lawyer's role in a mutual termination is concentrated in a few specific steps. First, reviewing the original contract for termination rights, notice traps and automatic renewal terms that could keep the contract alive. Second, drafting the termination document so the release, the survival list and the financial close-out line up with each other and with the original contract. Third, checking execution: the right people signing, with authority, and deed formalities handled correctly so the document cannot be attacked later. Fourth, sequencing the operational close-out, including customer communications that stay on the right side of the Australian Consumer Law and any privacy obligations around customer data. A lawyer will also advise on carve-outs, so a release drafted to end one dispute does not quietly extinguish a claim worth more than the exit.
The release decides whether the exit is clean
The single step most likely to determine whether a mutual termination holds is the release and its carve-outs, because that is the clause that decides whether the relationship can come back. The step people skip is checking what they give up when they sign a broad release, and the step people rush is the money reconciliation that the release then locks in. Get the release, the survival list and the final numbers right, and the exit holds. Get them wrong, and the dispute simply starts six months later.
In short: check the original contract before you negotiate, reconcile the work and money first, choose between an agreement and a deed with the right people signing, draft for survival and carve-outs rather than goodwill, and coordinate the operational close-out so the paper and the reality match. A signed termination deed is only as clean as the decisions that went into it.
