Guardianship of husband. Court declared we have to split our accounts. What can we do?

Last year, my daughter and I became co guardians of my husband. However, we have been married for 40 years and all of our savings are combined. I went on disability a few years ago, never had a 401k, but I did have savings, however it is in both of our names. The court is now telling me that I have to take everything that we had, and separate it into his money and mine. His medical expenses and personal expenses with come from his account, and mine from my account, but for things like our shared home and food and bills will have to come equally out of both of our accounts. I am elderly as well, and English is also not my first language. This is now a heavy inconvenience, and so much extra accounting and transferring of funds. If I pay a bill from his account, I have to drive to the bank to make a deposit into his account. How/why did they decide this was a good idea? Is this normal? We have a court budget but now they want this. Thoughts on why?
