However, it is a criminal offence to plant it, or otherwise cause it to grow in the wild. In fact all reasonable steps should be taken and due diligence exercised to avoid spreading the plant.The property information form that a seller completes when marketing their home has a section on Japanese Knotweed. The seller must disclose whether the property is affected by the plant, and if it is, they must also say whether a management plan is in place to deal with it, and provide a copy of any such plan.Furthermore, a valuer carrying out a mortgage valuation for a lender must note on their report if Japanese Knotweed is present.Some lenders may automatically refuse to lend where there is a presence of Japanese Knotweed, while others will lend but will wish to know there is a treatment plan or management plan in place, and will usually require an insurance-backed guarantee. Most lenders will look at each case individually and will consider their valuer's comments.Do remember that in view of the invasive nature and rapid spread of Japanese Knotweed, it can be an issue for lenders even when it is only present in a neighbouring garden and not actually in the garden of the property to be mortgaged.
