Ha! What a bunch of muppets they are. This could be very interesting and you should NOT try and cure their mistake because:
1. There’s no legal duty to help a claimant correct their own procedural or data error.
2. If they try to sue the wrongly named person, that’s a claim against a non-existent defendant — an automatic procedural failure that can’t be salvaged without court permission and cost consequences for them. Even if you never responded to the claimant and a default judgment was made, it would be a nullity as no such person exists.
If a claim ever does arrive in the wrong name, you can either (a) let it collapse, then apply to set aside if a default is entered; or (b) make a proactive non-party application early to strike it out and recover your costs.
3. If they instead try to revert to the keeper, they’re barred by PoFA as liability has already been correctly transferred and the statutory deadlines for keeper pursuit are long expired.
4. Silence also avoids giving them any excuse to “rectify” the record and start again cleanly.
In short, doing nothing keeps them boxed in whichever way they turn:
• pursue the wrong name = invalid claim
•revert to the keeper = no lawful basis
Keep all letters and envelopes as evidence of their misaddressing, and don’t respond unless something arrives either in the keeper’s correct name or in your own correct name. That’s the point where a reply is strategically necessary.
Let us know if that or any other correspondence is received.
