Only someone with a degree could say they had one, but have never "used it". There is so much you just learn, particularly in law, that is relevant in any employment and life generally. No one would ever take you for a fool again. Because if you don't know the specific legal details of a situation, you would be able to find the relevant information and use it. Time and time again.
I have a 2.1 law degree from London University. I did this at with a young son. Dh was quite helpful there. I loved it. After the degree, and this is where you will be disappointed, you need £10k to do the one year professional legal course. Only the very, very best 5% have their fees paid by a law firm who want to employ them when they come out of the course. You will have to find £3,300 per term.
Also, by year 3 I realised I had made a mistake; everyone else who actually wanted a job in law had been networking since the beginning of year 2. In law networking is everything, especially if you are handicapped by age/children when, frankly, there are free and single 22-year-olds available. Unfortunately, that is the reality.
If I were you I would go to a few local law firms, with enthusiasm, and ask about possible future placements... they will love the dedication.. the degree, and I assume you are perfectly competent, is secondary.
If all that sounds like a hassle, maybe you should think again.
Although I didn't get to do the solicitors training course, I use my law degree all the time. Because we are all involved in employment, financial, housing situations all the time. And without my law degree I would have been in very unhelpful situations and I have taught more than a few people/organisations some lessons along the way!
Good luck OP.
