Prescribed Information

Tenancy Deposits

I have a tenant who is stating that he "cannot recall" receiving the prescribed information about the protected deposit.
The court have stated that they intend to do this by a statutory declaration, in other words, sworn on oath.
I believe the tenant does not have to sign for the information, just that he is "served"
This is preventing the section 21 going through, (we have an order but the tenant has raised this issue)
Question is, can we reserve the information, he would not have to accept, the mere service of the docs should be sufficient, then resend the section 21, wait the 8 weeks or whatever, and then put the matter into court again.
Or, is this complicating matters. My wife is ARLA trained, but it seems that we haven't got a signed receipt.
Regards,
Stephen
