Ask an Property Solicitor. Get an Answer ASAP.
Hello my name is Alex and I will help you with this. Please note that I am a working Solicitor and may be on and offline as I have to attend Court and meet with clients, even at weekends. As such you may not get an instant response when you reply as this is not an ‘on demand’ live service, but rest assured I will be giving your question my immediate attention upon return. There is no need to wait here, you will get an email when I reply.
Sadly the law requires a party wall agreement.
The only reason this needs NOT be done is by consent.
Therefore if they do not consent you need to send a party wall agreement and then subsequent surveyors
But if you do not they can get an injunction to stop you.
The only way you do not need an agreement is if they consent
Clearly they do not and this means you need to go through the process
The fact you did not require one when THEY did the works previously does not matter. You consent not to having one then
But for the new works you must have one
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?
If this answers your question could I invite you leave feedback on my service which I hope has been excellent today, if you need more information or help then please click reply.
Please remember that I am always happy to help if you have future questions, even if I am in Court I can normally respond within a few hours. For future information, please start them with ‘For Alex W’.
