Please note that if you have been warned about your file being passed to HMRC’s Solicitor’s Office or have been served a statutory demand or winding-up petition do not delay in taking legal advice. Your matter can be handled more effectively the sooner you contact us.


The Limitation Act 1980 sets out strict statutory deadlines within which you must bring litigation claims. Your legal rights will become irreversibly time-barred if you fail to take legal action (or defend a claim on time). Therefore, you should seek specific legal advice about your legal dispute at the very first opportunity so that you understand the time you have left. Failure to take advice or delay in taking action can be fatal to your prospects of success.

Please note that for regulatory reasons we do not offer any free advice.
