Where can art be bought safely?

There are several routes, each with its own logic: galleries offer certainty and advice, auctions offer excitement and opportunity, online platforms offer convenience, and fractional (co-)ownership opens the door on a smaller budget. None is universally best; they differ in the level of risk, in price and in the experience. Whichever you choose, your best protection is a vetted source, documented provenance (ownership history) and a work listed in a scholarly catalogue.
