You being downvoted just shows how HN struggles with things like law practice, which are outside this echo chamber.

In Denmark I received English copies of various work / housing contracts, with a very clear disclaimer "in case of any disputes, the Danish text applies". I believe we did the same in Italy with foreign clients - Italian binding text, English courtesy non-binding copy.

Such a copy is good enough to use for 95% of the negotiation process. Then, if it's a serious business contract, you get a sworn translator to check its accuracy before the final signing.

(In my case, since the Danish ones were standard contracts, I just checked that they didn't differ from the publicly available texts).
