If I remember correctly, courthouses are always destroyed when a city is conquered. On the other hand, when a civ loses one of their cities and then conquers it again, it does not have to build a courthouse there.
My question is, does a city become "mine" after building a courthouse, e.g. if I lose and then re-conquer it, will I have to build a courthouse again? Or do all cities remember only the original civ that built them, and only that civ doesn't need a courthouse?

All cities remember only the original civ that built them. It's much more cost-efficient in the long run to raze cities and resettle in the same place with your own settler given the oftentime nigh untenable cost of the courthouse building (and the fact that it can't be purchased).
