Hey!
Congratulations on the TC offer!!
From my understanding, the transition from criminal law to commercial law is likely to be quite difficult, primarily because you won’t have trained in any commercial practice areas. While it is sometimes possible to move from criminal law into areas such as white-collar crime and investigations, these are relatively niche areas and firms will often look for experience that is closely aligned with the work they do.
If your ultimate goal is to build a career in commercial law, I would personally continue applying for commercial law opportunities and, if possible, look at paralegal roles that would allow you to gain experience in a commercial practice area. That experience could make a significant difference when applying for commercial TCs or other roles in the future, and I’m a big advocate of the fact that anyone can secure a commercial TC if they are resilient and proactive with improving on their weaker areas (regardless of age, university, background, etc.)
However, I completely appreciate that this is a very difficult decision. A guaranteed route to qualification is not something to take lightly, particularly in the current market. Ultimately, I’d say it comes down to balancing the security of a TC now against your long-term career aspirations.
Best of luck with whatever you decide, and with the SH outcome too!
