Legal Question in Family Law in Florida

Your soon to be former spouse will be entitled to a share in the differnce between the purchase value and the appriciated value at the time of the divorce.

If you comingled your funds, if spouse contributed to the maintenance, upkeep, care etc. of your house (I assume this is what you are concerned about), then yes. Florida is an equitable division state - not a community property state. What she contributed is considered equitable - not all that she contributed because she has the use of the property as well and therefore only a portion will be considered.

Generally, no, your spouse is not entitled to property that you owned before you were married, though there are many exceptions. Even if the property appreciates, your spouse is still usually not entitled to a part of the property, despite what's been written here, though again, there are some exceptions.
