If your spouse secretly uses shared marital money to give large tips to a streamer or transfers it to someone outside the marriage: you can ask the court to divide the shared property without divorcing, and money transferred to the person outside the marriage can be sued for and recovered

In plain words

If your spouse, without talking to you, uses shared money to give large tips to a streamer, you can ask the court to divide the shared property even if you are not divorcing. At divorce, you can also have the other side get a smaller share or none. For money transferred to someone outside the marriage, you can sue the person who received it to return it, and even if they say they spent it, they still have to return it. But all of this means going to court, you pay your own lawyer's fees, and a first-instance trial takes several months.
