Business & Divorce
Complex Issues when family law includes businesses
Startups: Early Employees, High Level Employees & RSUs.
Startup founders going through divorce tend to face more complex issues during property division proceedings because their stake in the company could be worth a considerable amount of money or very little if the company fails.
Startups: Employees & RSUs/Equity.
For employees going through divorce, understanding the vesting and distribution schedule of their RSU grant becomes incredibly important because these schedules not only determine when the employee is awarded equity, but how much that equity is worth.
Startups: Founders & RSUs.
At Kaspar & Lugay LLP in Corte Madera, California, we help startup founders and business owners alike handle the challenge of valuating and dividing community property, including RSUs, in divorce settlements.
