You better be careful about those big things he's purchasing if it's not paying cash for them because any debt like that while you are married becomes also yours whether you name is on the loan or the credit. Lawyer told me as long as I wasn't separated (living in the same home) that anything purchased on credit becomes my debt also. Lawyer told me that even though I have left & live 2100 miles away 8 years ago that there are some debt that as long as I am married & not legally separated even though I have been gone this long, I could be responsible for even though my name wasn't on it & that was more like medical bills they could actually come after my farm here which was why I put it under an LLC but even that doesn't protect 100%. My lawyer said it just would take it off the radar because unless they look deeper at who is the owner of the LLD. You aren't legally separated & you are living in the same house so you aren't protected against any of his debt he creates....& yes, my marriage was in California

If it's debt that he's creating then it's equally yours. Otherwise it's sort of stupid on his part because all those assets that he pays cash for, are still assets that are to be split in the divorce.
