Ask an Property Solicitor. Get an Answer ASAP.
Hi, thank you for your message. I would recommend that you write them a final letter setting out your claim and attaching all relevant evidence. Unfortunately, boundary disputes are quite common and the boundaries set out by the land registry are not always correct (they tend to be estimates). For this reason the only way to resolve these types of disputes is to take the matter to court for a judge to decide the outcome based on all evidence before him. It would strengthen your case if you have any written evidence of what was initially said by the property manager. You can find a solicitor using the Law Society find a solicitor search option here: https://solicitors.lawsociety.org.uk. You can search by town or postcode to find one near you, as well as area of law.
