TUPE advice

I am in the process of acquiring certain assets from a small professional services business through an asset purchase agreement. The seller will be winding down their limited company separately.

As part of the acquisition I intend to offer employment to one member of the seller's existing team on a new contract with my own business. I am not taking on any other staff.

I need a qualified employment lawyer to advise me on:

1)Whether TUPE is likely to apply in this specific structure given I am taking one member of staff, certain client contracts and a brand but not the whole business
2) What steps I can take to mitigate TUPE risk in the way the transaction is structured and timed
3) How to structure the new employment contract to protect both parties

This is a one-off piece of advice rather than ongoing work. I would expect this to be relatively straightforward for an experienced employment lawyer and am looking for a fixed fee quote.

Requirements:
Must be UK based and qualified
Advice must be covered by professional indemnity insurance
Please only apply if you have specific experience of TUPE in the context of asset purchases and business transfers
