It is important to understand that encroaching on someone else's property is illegal and can result in serious legal consequences. In your case, your neighbor has constructed a compound wall on your property without your permission, which is a clear case of encroachment. Here are a few steps that you can take to address this issue: Try to resolve the issue amicably: Before taking any legal action, try to have a conversation with your neighbor and explain the situation. You can ask them to remove the compound wall and restore the land to its original state. Send a legal notice: If your neighbor is not willing to cooperate, you can send a legal notice to them. The notice should state that the construction of the compound wall is illegal and that they should remove it immediately. You can also ask for compensation for the loss of your land. File a police complaint: If your neighbor refuses to cooperate even after receiving the legal notice, you can file a police complaint. You can provide evidence of the encroachment, such as photographs and property documents, to the police. Approach the court: If all other options fail, you can approach the court for a resolution. You can file a civil suit for the removal of the compound wall and compensation for the loss of your land. It is important to act quickly and decisively in such cases, as delaying action can weaken your case. You may want to consult with a lawyer who specializes in property law to guide you through the process.
