In the UK legal insurance is often bundled with home insurance for a small fee (~£8 a month for me). This covers the cost of legal advice across a broad range of categories (employment, housing, consumer protection, personal injury are all usually included) and if a case is likely to succeed (more than 50% prospects of success as judged by the law firm) then they will cover all the costs up to a certain limit which is usually enough for most cases (say £50,000 or so).

It's not perfect but reasonably strong regulation of consumer insurance means that if you have problems with e.g the decision made, there is an independent organisation who can review the case for you.

You usually have to use a law firm which has an arrangement with the insurer, or one who will accept the lower rates the insurers have negotiated but again if you feel there is an issue with the quality on offer you can make a complaint.

I presume something similar is offered in NL.
