Yes, absolutely, whether in a law firm (eg look at the list of practice areas at one of the big London firms like Allen & Overy, Freshfields, Linklaters, Clifford Chance) or after a couple of years post qualification experience, within a bank/fund. As one example, there is (or certainly was) demand for ISDA specialists to document derivatives agreements. But in whatever form, it's a law job, not a trading job - if law itself interests you, you will likely discover more interesting areas to work in.
