Identifying signature on divorce petition

[paintedpanda]

I've just had the statement of support for my Decree Nisi through the post. My solicitor has asked me to sign it if it's all correct, but it asks about whether I can identify the signature on the acknowledgement of service as that of my STBXH. I can't, because I haven't seen a copy of the acknowledgement. Is this important? Should I just send it back to my solicitor signed (but without ticking the box to confirm I have identified it) and assume my solicitor will sort this?
I want to get this done as quickly as possible.

Leave the box blank. I would imagine the reason you haven't seen a copy is that your ex has a solicitor who has signed the acknowledgement on his behalf. If that is the case none of the boxes should be ticked.

Thank you for your advice. I don't think my ex has a solicitor. He was very against me using one.
