Ok - its bad news I am afraid. If the lease states you can't have pets then yes, they can get you to get it removed.
They could in theory apply for a Court order stopping you.
However it sounds like that your Solicitor may have been negligent. They should have pointed out that pets were not permitted and that you should know.
This is quite common in flats.
But they could force the removal but in any event your Solicitor is liable.
I am sorry if this is not the answer you want and certainly not the one I want to give you, but I have a duty to be honest
Can I clarify anything for you about this today please?
No appeal and Human Rights is only available against public bodies, ie Council or Government rather than private firms
If they apply for a Court order you will be notified and you can object to it
If you refuse to comply it is contempt of Court
I am sorry
Does that clarify?
I am sorry John its not better news.
Can I clarify anything else for you?
No, they can't enter without permission.
They MUST get a Court order
Does that help?
