in some states I believe it is illegal without the consent of both parties (in other states I think only one party needs to consent, and that can be the person doing the recording), Jim may know more. But it's something to talk to your L about.
The nuances vary, but the "two party consent" states are: California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania, and Washington.One of the notable nuances is that Massachusetts only bans "secret" recordings. Not sure how that is defined, but putting your spouse on notice that you will be recording future convos to protect yourself probably puts you within the bounds of the law. There are other exceptions-- at least one state has a spousal exemption, and there is also an "open conversation" exemption, maybe Illinois, and an exemption for in-person vice phone convos. Point is, in all states but the above 11 you can recorde ANY of your convos no matter who its with. In the 11 listed above, it is more restrictive and you would want to ask your lawyer. Personally, I'd do it anyway (You dont have to use it if you do and can always wipe it later) to protect yourself whether or not it is strictly legal. I'd much rather be on the bad end of an "unlawful recording" charge than the bad end of a "spousal battery" charge.
Fortunately I’m in a one party consent state! Will be looking for a good Android recording app.
