Some time ago I saw (In fact it might have been in a comic, possibly Zits.) an expression/proverb that basically said that being in possession of disputed goods meant that a civil lawsuit/quarrel was almost won before it had begun. Anyone know what idiom I am talking about and can remind me?
NB: I am not sure if it was in English or Latin. If possible I would prefer a Latin answer.
Edit: after learning about this nine-tenths idiom I found two similar latin expressions, possidetis, ita possideatis and qui tenet teneat, qui dolet doleat. Are there more or better latin expressions I should be aware of?
