Quick read

  • If your business depends on a founder’s name, designer label, celebrity brand or other licensed trade mark, do not leave duration and exit rights to later argument.
  • Zaha Hadid Limited v The Zaha Hadid Foundation is a Court of Appeal decision about how to read a long-running trade mark licence when the contract does not clearly give...

Use this to check

  • A contract that continues “indefinitely” is not automatically perpetual.
  • Express termination rights for one party do not always exclude a notice-based termination right for the other.
  • If a business trades under a licensed brand, the licence is a core operating contract, not a side issue.

Decision snapshot

  1. What happened

    • Zaha Hadid Limited operated as an international architecture practice founded by Dame Zaha Hadid.
    • The Zaha Hadid Foundation was set up by Dame Zaha to preserve her work and legacy.
    • The dispute concerned a trade mark licence for the ZAHA HADID marks.
    • The licence was dated 1 May 2013, although it was signed in 2014.
  2. What the court had to decide

    • The main issue was whether a trade mark licence stating that it would continue “indefinitely” could be terminated by the licensee on reasonable notice, even though the contract only gave express termination rights to the licensor.
    • The Court of Appeal had to construe clause 12 in the context of the agreement as a whole and the commercial background.
  3. What the court decided

    • The Court of Appeal allowed the company’s appeal on the termination issue and overturned the High Court’s conclusion that the company was locked into the licence unless the licensor chose to end it.
    • The court held that this agreement was intended to be of indefinite duration, not perpetual duration, and that a power to terminate on reasonable notice should be inferred to give effect to that construction.
    • In reaching that result, the court stressed that “indefinitely” and “perpetually” are not synonyms, and that the licensor’s express termination rights in clause 12.2 and clause 12.3 were not inconsistent with a notice-based termination right for the company.

Practical impact

Practical read

  • If your business depends on a founder’s name, designer label, celebrity brand or other licensed trade mark, do not leave duration and exit rights to later argument.
  • This case shows that “indefinitely” does not automatically mean forever, even where the contract gives one party express termination rights and says nothing clear about the other.
  • A business should check at least four points before signing or renewing a licence: who owns the mark, how long the licence lasts, who can end it, and what happens operationally after termination.
  • Royalty drafting matters too.

Useful next steps

  • A contract that continues “indefinitely” is not automatically perpetual.
  • Express termination rights for one party do not always exclude a notice-based termination right for the other.
  • If a business trades under a licensed brand, the licence is a core operating contract, not a side issue.
  • Royalty clauses should be tested carefully, especially if they may apply to revenue beyond work actually using the brand.
  • Brand licences should deal expressly with duration, notice, post-termination use, rebranding and transition steps.

The story

This dispute came from a business built around a famous founder’s name. Zaha Hadid Limited ran the architecture practice founded by Dame Zaha Hadid. The Zaha Hadid Foundation later held the trade mark rights for the ZAHA HADID name after Dame Zaha’s death.

The company wanted to keep using the ZAHA HADID name, but it also wanted to renegotiate the economics of the licence. Its main complaint was the royalty structure. Under the agreement, it had to pay 6% of net income for a broadly defined category of services, and the court noted that this was not limited to services actually using the trade marks.

That commercial tension turned a drafting point into a major dispute. The licence said it would continue “indefinitely”. It also gave the licensor express rights to terminate. But it did not clearly say whether the company, as licensee, could bring the arrangement to an end on reasonable notice.

Practical sense check

  • Check whether your business owns the brand or only licenses it
  • Read the duration clause separately from the breach and insolvency clauses
  • Check whether both sides have express termination rights
  • Test whether royalties apply only to branded work or to wider revenue
  • Plan what happens if the business must stop using the name

How the contract was set up

The licence was dated 1 May 2013 and signed in 2014. Dame Zaha was the original licensor and the company was the licensee. The marks covered relevant services, and the territory was worldwide.

The Court of Appeal described the agreement broadly as a conventional trade mark licence. It included provisions on ownership of the marks, goodwill, quality control, marketing, protection of the marks, sublicensing and assignment. Those terms mattered for context, but the appeal turned on the duration and termination wording.

Clause 12.1 said the agreement would continue indefinitely unless terminated earlier in accordance with clause 12. Clause 12.2 gave the licensor a right to terminate on at least 3 months’ written notice. Clause 12.3 gave the licensor immediate termination rights for non-payment, material breach, repeated breach and insolvency-related events. There was no matching express right for the company.

Clause 13 then dealt with the effect of expiry or termination. In practical terms, rights and licences would cease, and outstanding sums would become due. So the contract clearly contemplated an endpoint. The real question was how that endpoint could be reached if the company wanted out.

Key points

  • Non-exclusive worldwide licence
  • 6% royalty on Net Income for Licensed Services
  • Licensed Services defined broadly
  • Licensor control over use, goodwill and standards
  • Express termination rights for the licensor only

What the court had to decide

The first issue was contract construction. Did this licence, properly read, allow the company to terminate on reasonable notice even though the contract only gave express termination rights to the licensor? The company said yes. The Foundation said no.

The High Court had accepted the Foundation’s reading. It held that the company had no such right and was effectively locked into the contract unless the licensor chose to terminate. The company appealed.

The second issue was restraint of trade. The company argued that if the contract gave it no right to terminate, the arrangement was an unreasonable restraint of trade and therefore void. But that was a fallback argument. Once the Court of Appeal found for the company on construction, it did not need to decide the restraint of trade point.

The appeal therefore became a close reading exercise. The court had to decide what a reasonable person, with the relevant background knowledge, would understand the contract to mean when it said the agreement would continue “indefinitely”.

What the Court of Appeal decided

The Court of Appeal allowed the company’s appeal on the termination issue. It held that the agreement was intended to last for an indefinite period, not to bind the parties perpetually. To give effect to that construction, a power to terminate on reasonable notice should be inferred.

A key point in the reasoning was simple but important. The contract used the word “indefinitely”, not “perpetually”. The court said those are not synonyms. An agreement of indefinite duration contemplates that it can be brought to an end at some unspecified future time. A perpetual agreement does not.

The court reviewed earlier authorities on contracts with no fixed term. It drew a two-step approach from them. First, decide as a matter of construction whether the agreement was intended to be perpetual or merely indefinite. Second, if it was indefinite rather than perpetual, a power to terminate on reasonable notice follows in order to make that construction work.

The court also rejected the idea that the licensor’s express termination rights in clauses 12.2 and 12.3 necessarily excluded a notice-based termination right for the company. Those provisions were not inconsistent with such a right. Clause 12.3 dealt with immediate termination for default. Clause 12.2 gave the licensor a 3-month no-fault termination right. The existence of those rights did not force the contract into a perpetual reading.

The court said the wider trade mark context did not support a one-sided perpetual lock-in either. Trade mark licences often contain controls over quality, goodwill and use because of the nature of trade mark law. That does not, by itself, show that only the licensor should have termination rights.

The court also considered the commercial setting. It was common ground that the company was expected to become more independent over time, with equity intended for Mr Schumacher and others. Against that background, the idea that an independent professional practice might one day want to change its name was not far-fetched. That pointed away from a perpetual arrangement.

How the reasoning worked in practice

The judgment is useful because it shows how a court tests rival readings of the same clause. The Foundation’s case was that “indefinitely” really meant the contract would go on forever unless the licensor chose to end it under clause 12.2 or 12.3. The Court of Appeal rejected that reading.

The court said the first part of clause 12.1 was the obvious place to find the parties’ intention about duration. On its face, the agreement was of indefinite duration. That did not mean the relationship had to last forever. It meant there was no fixed end date.

The court then tested whether the rest of clause 12 made a notice-based termination right impossible. It concluded that it did not. A right for the company to terminate on reasonable notice could sit alongside the licensor’s express rights. The licensor’s immediate rights for breach and insolvency still had work to do, and the licensor’s 3-month notice right still had work to do.

The court also noted that what counts as reasonable notice depends on the circumstances at the time notice is given. So the practical effect of a notice right may change over the life of a long-running contract. That was one reason the court did not need to decide whether 12 months was the right period here.

Key points

  • Step 1 - decide whether the contract is perpetual or indefinite
  • Step 2 - if it is indefinite, ask what mechanism lets it end
  • Check whether express termination rights are inconsistent with a notice right
  • Read the clause in the context of the whole agreement
  • Test the result against commercial common sense without rewriting the bargain

Points the court did not decide

The judgment is useful partly because of what it did not decide. First, the court did not decide that 12 months was the correct notice period. It recorded that the Foundation accepted 12 months would be reasonable if such a right existed, but said it did not need to determine that issue.

Second, the court did not decide the restraint of trade argument. It said it preferred to leave that topic for a case where it actually mattered to the outcome. So this decision should not be read as a substantive ruling on whether this licence, or trade mark licences generally, offend the restraint of trade doctrine.

Third, the court did not create a universal rule that every contract of indefinite duration is terminable on notice. The reasoning was tied to the wording of this agreement, the structure of clause 12 and the commercial context.

How businesses should read it

This decision matters to any business that trades under a name it does not own. That includes founder-name businesses, family businesses, group companies using centrally owned brands, and businesses licensing a celebrity or designer name.

If the trading business does not own the mark, the licence is not just an IP document. It is a core operating contract. It can affect pricing, margins, branding, customer communications, investment value and even whether the business can keep its trading identity.

The case also shows how a short duration clause can carry major commercial risk. If the contract is silent or unclear on exit, the parties may end up in expensive litigation over whether one side is trapped, whether notice can be given, and how long that notice should be.

Another practical point is royalty scope. Here, the court noted that the royalty applied to a broad category of services and was not limited to services using the marks. That kind of drafting can become contentious as a business grows, diversifies or changes its service mix.

There is also a governance point. Where a founder, estate, foundation or holding vehicle owns the brand, the trading company may be commercially dependent on a relationship it does not fully control. That should be recognised early, not only when the economics become difficult.

In practice

  • Treat a brand licence as a business-critical contract
  • Do not assume “indefinitely” means forever
  • Do not assume express rights for one side automatically exclude rights for the other
  • Stress-test royalty wording against future revenue streams
  • Plan for succession, founder death, sale or management change

Documents and conduct

This case was about contract wording, but the surrounding conduct still mattered. The company had actually served notice in March 2024 saying it would treat the agreement as ending 12 months later. After the High Court ruled against it, the company continued to use the marks and pay royalties while the appeal was pursued.

That sequence is a reminder that once a dispute starts, day-to-day conduct can become important. A business may need to decide whether to keep performing, whether to reserve its position, and how to manage customer-facing branding while the legal position is unresolved.

For owner-managed businesses, the practical burden can be heavy. A dispute over a licensed trading name can affect proposals, websites, social media, signage, investor discussions and staff confidence. The contract should therefore deal not only with legal rights, but also with the operational steps that follow if the relationship ends.

Documents to keep in order

  • Keep clear records of any notice served under the licence
  • Check whether the business should continue paying royalties during a dispute
  • Review website, domain, signage and social media dependencies
  • Prepare customer and supplier communications if the brand relationship changes
  • Map which materials can still be used after termination and which must stop

Documents and clauses to check now

If your business uses a licensed name or logo, review the agreement before the relationship becomes strained. The best time to negotiate exit mechanics is at the start, not after the economics have become contentious.

Focus on the clauses that affect both day-to-day trading and long-term flexibility. Duration and termination are only part of the picture. Royalty scope, quality control, assignment, sublicensing and post-termination obligations can all affect whether the business can continue smoothly if the relationship changes.

Sense check

  • Confirm who owns the trade mark now
  • Check who will own it after death, sale or succession events
  • State clearly whether the licence is exclusive or non-exclusive
  • Say whether the licence is fixed-term, indefinite, perpetual or terminable on notice
  • Give each party express termination rights if that is the commercial intention
  • Set a notice period or a method for deciding what is reasonable
  • Define exactly which services and revenue streams attract royalties
  • Check whether quality control obligations are workable in practice
  • Deal with assignment, sublicensing and group company use
  • Set out what happens to websites, signage, proposals and social media on termination
  • Include a rebranding and customer communication plan
  • Check whether the business can keep using any legacy portfolio material after exit

Drafting points before you sign or renew

The cleanest lesson from this case is drafting discipline. If the parties mean “ongoing unless either side gives notice”, say that. If they mean “perpetual unless the licensor ends it”, say that too. Do not rely on broad words like “indefinitely” to carry a commercial arrangement that may later be tested in court.

For founder-name businesses, the contract should also reflect identity risk. A business may spend years building goodwill in a name it does not own. If the licence ends, the business may need to change its trading name, domain names, pitch materials and customer messaging quickly. That operational risk should be priced, planned for and documented.

It is also worth checking whether the royalty model still makes sense if the business expands into new services, new territories or new channels. A clause that seems acceptable at the start can become commercially difficult later if it captures revenue that the parties did not really have in mind.

Finally, think about control rights and commercial leverage together. A licensor may need quality control and brand protection rights. A licensee may need certainty that it can exit, rebrand and keep operating. Good drafting should deal with both sides openly rather than leaving the balance to later litigation.

Dates and status

The Court of Appeal judgment was handed down on 27 February 2026. It was an appeal from the High Court decision of Adam Johnson J, who had ruled against the company in December 2024.

The Court of Appeal allowed the appeal on the termination issue. It held that the agreement was of indefinite duration rather than perpetual duration, and that a power to terminate on reasonable notice should be inferred to give effect to that construction.

The court did not decide the restraint of trade issue because that was unnecessary once the company succeeded on construction. For business readers, the durable lesson is about contract wording in trade mark licences and the commercial risk of unclear exit drafting.

Common questions

Did the Court of Appeal say that “indefinitely” means the same as “perpetually”?

No. A central part of the decision was that “indefinitely” and “perpetually” are not synonyms. The court held that this agreement was intended to be of indefinite duration, not perpetual duration, and that this supported a right to terminate on reasonable notice.

Did the court decide that 12 months was reasonable notice?

No. The judgment records that the Foundation accepted 12 months would be reasonable notice if a right to terminate on notice existed. But the Court of Appeal said it did not need to decide that point.

Was this only about trade marks?

The dispute was about a trade mark licence, but the practical lesson is wider. Any business using a brand, founder name or other IP it does not own should check duration, termination rights, royalty scope and post-termination steps carefully.

Did the court rule on restraint of trade?

No. The company argued in the alternative that if it had no right to terminate, the arrangement was an unreasonable restraint of trade. Because the appeal succeeded on contract construction, the Court of Appeal left that issue undecided.

Does this mean every indefinite contract can be terminated on notice?

No. The court was construing this contract in its own wording and context. The decision is a strong reminder to draft clearly, but it is not a blanket rule that every contract of indefinite duration will always be terminable on notice.
