Developer disappeared? What to secure in the first week

What to secure when the person building your system disappears, what UK law says you own, and how to decide what happens next.

Updated 4 October 2026 · 9 min read

The short answer

If the person or firm building your system has gone quiet, secure four things this week: the web address, the hosting account, a copy of the system with its data, and every login. Change the passwords you control and cut off their access to customer data.

Then find out what you own. Under UK law the developer keeps the copyright unless they were your employee or signed it over to you in writing. Without that, you may have a right to keep using the system and not much more.

The posts on forums read alike. A deposit paid, a system that half works, a developer whose replies got slower and then stopped. Sometimes the developer is ill, sometimes they have taken a full-time job, sometimes their company has gone under. The reason matters less than the first week, because the things you most need are usually still within reach while everybody is being polite. Agencies call what follows software project rescue.

Day one: secure what you can reach

  1. The web address. Find out whose name it is registered in. If the renewal reminders have never reached you, it is probably sitting in somebody else’s account. If it is the developer’s, ask for a transfer now, while relations are civil. For a .uk address the current holder starts the transfer and pays Nominet £10 plus VAT, and you have five days to accept it.
  2. The hosting account, meaning the company whose computers the system runs on. Find out whose card pays for it. If it is the developer’s, the system disappears the month that card stops being charged. Ask for the account to be moved into your company’s name, and get a full copy out before anything else.
  3. A copy of the system and its data. That means the source code (the files another developer would need to run and change it), a full copy of the data it holds, and any notes on how it is set up. Ask in writing.
  4. Every login. List them: hosting, domain, the service that sends its emails, the payment provider, the app store accounts, the connection to your accounts package. Change the passwords on everything in your name, and remove the developer’s access to anything that holds customer data.
  5. The app store listings, if there are any. Apple and Google both let an app move from one developer account to another, but only the current holder can start it. Apple also needs the app to have had at least one version released, and the receiving account has 60 days to accept.

Who owns what was built

UK copyright law treats software as a literary work, like a book. The author owns it first. If the author was your employee, doing their job, it is yours. If not, it stays with the author unless they have assigned it to you in a signed document. Work done by an agency’s own staff belongs to the agency to begin with, not to the client.

Your situationWhat you probably have
A signed contract with a clause assigning the copyright to youOwnership. A refusal to hand over the copy is a breach of that contract.
A contract that says nothing about copyrightProbably a licence to use, repair and improve it for your own business. In Clearsprings v Businesslinx (2005) the High Court found exactly that: a licence that was permanent and free, but not exclusive, not transferable to anyone else and not ownership.
No contract, only emails and invoicesThe same starting point, decided on the facts. In Griggs v Evans (2005) the Court of Appeal held that a client owned a logo it had commissioned, because everything about the arrangement showed it was always meant to be theirs.
Built by your own employee as part of their jobOwnership.
Built on the developer’s own product, which you rentThe product stays theirs. Your data is yours, and so may be the parts made only for you.
This is the general position, not legal advice. If the developer refuses to hand anything over, speak to a solicitor before you speak to anyone else.

In practice, start by assuming the developer is overwhelmed rather than hostile. A short written request that lists exactly what you want, and offers to pay any undisputed invoice for finished work in return, tends to get more back than a threat does.

Rescue it or start again

Once you have a copy, somebody independent needs to read it, run it and check the data. A few days usually answers four questions.

  1. Can anyone other than the original developer run it? If it only works on their laptop, everything else waits until it works somewhere else.
  2. How much of what you were promised exists and works? Count working screens against the original quote, not against the developer’s last update.
  3. Is the data sound? A system can be rewritten. Three years of customer records cannot.
  4. Is it built on parts that still get security fixes? If not, they have to be brought up to date before anything else, and nobody using the system will see that work. Software maintenance and support explains why.

Rescue it when most of it works, the data is sound and the parts are current. Start again when nobody else can run it, or when bringing it up to date costs most of a rebuild. Either way, keep the data and everything the first attempt taught you about the process. A second build goes faster because the first one found the awkward cases.

Making sure it cannot happen twice

  • A signed clause assigning to you the copyright in everything written for you, on payment. What bespoke software is explains why this matters more than the price.
  • Every account in your company’s name from the first day: domain, hosting, app stores, email services. The developer gets access, never ownership.
  • A copy of the system delivered to you every month, so you are never more than a month behind.
  • Payments tied to working things you can see rather than to dates. Fixed price or time and materials covers how.
  • A written handover clause: what you receive at the end, and in what form.
  • More than one person who has seen the system. A single freelancer is fine for a small job. For a system the business runs on, choose a supplier where somebody else can pick it up.

Common questions

My developer has disappeared. What do I do first?

Secure the four things you cannot easily replace: the web address, the hosting account, a copy of the system and its data, and the logins. Change the passwords on everything in your name and remove the developer’s access to customer data. Then ask in writing for everything else.

Do I own the software I paid for?

Only if the developer was your employee, or signed a document assigning the copyright to you. Paying the invoice does not transfer it. Without an assignment, a court may still decide you have a licence to keep using and repairing it for your own business, or occasionally that it was always meant to be yours and so belongs to you.

Can another company finish my project?

Yes, once they have a copy of the system and its data. A good one will spend a few days reading and running it before quoting, and will tell you if starting again is cheaper.

What if the developer refuses to hand anything over?

Put the request in writing and keep it factual. If they hold your customers’ personal data, the written contract data protection law requires them to have with you must say they return or delete it, at your choice, when the work ends. Beyond that, your rights depend on the contract, and a solicitor is the next step.

How do I get my domain name back?

For a .uk address, the current holder starts a transfer with Nominet, which costs £10 plus VAT, and you accept it within five days. If they will not, the options are a court order or Nominet’s dispute service, which costs £200 for a quick decision and only succeeds if keeping the address from you is judged unfair. For a .com address, the change goes through the company the address was bought from, and it may then be locked to that company for 60 days.

How much does a rescue cost?

The assessment takes days rather than weeks. What follows depends on what the assessment finds, and the honest comparison is against the cost of building it again, which [the cost guide](/guides/custom-software-cost-uk) sets out.

Tell us what is not working

Describe the process that is costing you time. If software is the wrong answer we will say so, and if a product already covers it we will name the product.

From £10,000Most projects land between £15,000 and £55,000.
