Ask an Property Solicitor. Get an Answer ASAP.
Good morning, thank you for your question, I am sorry to hear of your situation. I appreciate that it will be a wrench for the sibling to have to move, but your first step is a county court application for an Order for Possession. Once you obtain this (they may defend it) you can then apply for the baliffs to evict them and change the locks.
hello do you need any further assistance?
