Since 2013, the seller is required to state whether Japanese knotweed (Fallopia japonica) is present on their property through a TA6 form – the property information form used for conveyancing. Your conveyancer or solicitor will be able to provide full legal advice, however, here is a summary:
- If you are selling, it is your responsibility to check the garden for Japanese knotweed (bearing in mind that it can die back in winter). The TA6 form asks you to confirm whether your property is affected by Japanese knotweed and, where it is, to provide a management plan for its eradication from a professional company (see Seeking help from the professionals below)
- If you are buying, the presence of Japanese knotweed will be stated in the responses to the TA6 form. This often results in your mortgage lender requiring assurances that it will be eradicated before agreeing the funds. A management plan by a professional eradication company, backed by a transferable guarantee, is usually sufficient. It is most common for this plan to be provided by the seller before the purchase is completed.
