Step one is classification: marital property (generally what was acquired during the marriage) versus nonmarital (premarital assets, gifts, inheritances kept separate). Commingling and appreciation of nonmarital assets during the marriage are the classic complications.
Businesses, professional practices, intellectual property, and crypto need valuation — this is where appraisers and forensic accountants earn their fees, and where attorney review is strongly recommended.
Valid premarital or postnuptial agreements (§ 61.079) can control the outcome. Debts are part of distribution too — and creditors are not bound by who the judgment says must pay.
Attorney-review note: Business valuation, hidden assets, and QDRO mechanics are attorney/expert territory.
