A living trust does not complicate the management of your assets. While protecting your property within a living trust, you can do whatever you can do now with your assets and property.
In a divorce or legal separation case, you can ask the judge for orders that may include child custody, visitation, child support, spousal/partner support, the division of assets and debts, and restraining orders.
After you are divorced, or the court grants an annulment, you will be single, and you can marry or become a domestic partner again. A legal separation does not end a marriage or domestic partnership.
