I inherited $246K from my late mother and used $142K to pay off our mortgage. If we divorce, can I claim this money back from my husband?

Dear Quentin,

Four years ago, I inherited $246,000 from my mother’s estate. I had always promised her that I would pay off my mortgage when she passed. My husband and I jointly own our home and have both equally contributed to the mortgage and household bills for the past 23 years. 

Both of our names are on the deed….
