In Florida a spouse MUST sign at closing (we do NOT have a legal separation, it's an all or none deal, either you're married or divorced) to acknowledge a mortgage on a primary residence. We have "homestead" laws that protect a spouse's interest in the "homestead".
Your spouse (you're still married until you actually finalize your divorce) must sign and she may now actually have a financial interest in the house you just bought!
Contact a divorce attorney and take care of it!
All the best,
It's more than real estate. It's RAYL-Estate!
