How do you split depreciation onto two Schedule Cs for a business owned by both husband and

My husband and I have owned our business for years, but have always shown that my husband only has owned it on our taxes.  This year, we're filing a separate Schedule C to show that we both own it, and divided all income and expenses, but all the depreciable assets are on his schedule.  Any way to split that?  If not, our income levels are really uneven, to the point of showing him at a loss.
