How can I prove that I have served a legal document? I can

What was being served on them? 

I also wanted to make you aware that this is not always an instant service, due to various legal engagements I could have and I may not be able to reply immediately. However, rest assured that I am dealing with your query and will get back to you as soon as I can. Thanks.

Thanks, ***** ***** denying that they received anything at all, or just that the notice was not in the envelope?

Thank you very much for clarifying. First of all, I am sorry to hear about the issues brought up by this. It must be a frustrating situation to go be going through.

The short answer is that you cannot prove what was sent in the envelope – it is too late for that now as you did not take any evidence at the time (such as photos of the contents, together with the actual envelope, etc). However, that is not required anyway and people are not ordinarily required to take such evidence to prove service of a document.

It is enough to have your own personal evidence, or an affidavit, confirming that the document was sent out and therefore should be considered served. They could try and say it was not received but you still have more proof than them, in the form of proof of delivery of correspondence, together with your own evidence of what was in it.

Hopefully, I have answered your query in a way that is simple and easy to understand. If anything remains unclear, I will be more than happy to clarify it for you. In the meantime, thank you once again for using our services.

There are also companies who are known as ‘process servers’ and who can serve official documents to third parties and provide a sworn affidavit confirming service has taken place.
