I went through this when my husband's ex tacked on a motion to revisit child support when he took her to court for visitation contempt and he had to do a financial affidavit and I had no choice but to supply my income and assets because it's household income and the assets are comm property. She dropped her motion b/c she had already filed something with the DA to reassess who does NOT require info about the spouse or other household income so I think she did it on purpose to find out our financial info, but there was no way out of it. Chances are if the financial affidavit had been scrutinized and my info not on there (would have been obvious), his contempt motion re: her would have been thrown out and he could have been the one paying her attorney's fees so like it or not, I coughed up the info.
