Can I Sue Previous Owner? Building Regulations Fix
Key Takeaways
- You can only sue the previous owner over a building regulations fix if they made a 'misrepresentation' that the work was compliant.
- The local authority cannot enforce alteration or removal of the work, more than 12 months after the work has been completed. However, non-compliant building work will continue to effect the property's value, let-ability, saleability, and the building may still be dangerous.
- There are several options for resolution including retrospective sign-off, insurance and remedy or removal of the offending work.
What happens if I buy a house without building regulations?
- The SellerYou can only sue the previous owner if they have misrepresented the property to you. They might have lied directly, pretended not to know the answer to a question, or given the impression that they did know, when really they didn't. Only a property litigation solicitor will be able to assess your situation to give you an idea of whether you have a claim.
- The Seller's SolicitorIt might not be the seller's fault directly, perhaps their solicitor made a mistake in the information they gave to you, or they gave the seller bad advice. You can't complain about a solicitor who was not acting on your behalf, so you may still need to begin a claim against the seller, who would then have to sue their own solicitor for professional negligence. A property litigation solicitor will be able to assess the merits of taking this course of action in your case.
- The Seller's AgentIf the seller's agent has lied, or misrepresented the property to you, it may not be their fault, it may be down to a mistake or a lie told to them by their seller or their solicitor. However, if they have breached their duty of care to you, you suffered financial or personal damage (i.e. you paid more than the house was worth, or you're having to pay to fix the unregulated building), and you can prove that this damage was caused by the negligence of the agent, you can begin a professional negligence claim. Speak to a property litigation solicitor for advice on if and how you should proceed.
- YoursAs we mentioned before, in most cases it is the buyer who is ultimately liable for buying a house with a building regulations problem. If this is the case, your options are to purchase indemnity insurance, apply for retrospective sign-off, or, if you're unlucky, you'll have to have the building work undone or redone with proper certification. We'll discuss these later.
- Your SurveyorYour surveyor would usually find signs of building work which is unsafe, or obviously not up to building regs. However, homebuyers and buildings surveys are non intrusive, so if work was done to the house and then disguised, they could not reasonably be expected to uncover it. If there is visibly a wall missing where there should be one on the title plans, or if the stairway to a recent loft conversion, for example, does not meet regs, and your surveyor failed to report this, then you may be able to bring a professional negligence claim against your surveyor. Speak to a property litigation solicitor first.
- Your SolicitorNow, in some cases, your solicitor may have let you down. If they did not carry out the relevant, necessary checks, or they gave you bad advice when they should have known better, you may be able to bring a claim against them for professional negligence. As with a professional negligence claim against an estate agent, you will need to be able to show that they breached their professional duty of care to you and that you suffered financial or personal damage as a result of this breach. Speak to one of our hand selected property litigation solicitors to find out what you can do.
