Arizona is a community property state, which means assets accumulated during the marriage are generally presumed to be the equal property of both spouses.
Unfortunately, a staggering number of spouses hide their finances from one another. It's also not uncommon for people who are contemplating divorce to start setting aside money or start buying items for personal use. But because that's community property, failing to disclose such actions during a divorce may amount to hiding assets.
And lying during divorce proceedings -- including hiding assets -- is illegal.
