Although it may be possible to find out whom bought Laing's assets - you still have to PROVE liability.
The cost to litigate will probably not be worthwhile - even with a significant claim.
Check with a local law firm - and see if any of them will take the case without an up front fee. The call this taking the case on contingency.
