Can my soon to be ex husband rent out joint property we own without my consent?

The issue of whether or not the leases are enforceable by the tenants, could go either way. Technically, each cotenant has the right to enter and occupy all of the property at any time. So when one cotenant tries to lease the property, the other cotenant has the right to interfere with that lease by showing up and sitting down at the kitchen table or lying down in the bed at any time. However, don't try to do that. There is the legal doctrine of apparent authority. The tenants may reasonably believe that the cotenant who entered into the lease had the authority to do so. The tenants have no way to know that the divorce was pending. In choosing between the innocent tenants and parties to a contentious divorce, the decision is likely to go to the tenants. The real issue is what can your attorney and the court do to make this up to you? You need to discuss available alternatives with youf divorce attorney. Did he get market rent? If not, then maybe he owes you your share of the difference. Maybe the court can order that all the tenants be told that their leases will not be renewed and offering to let them cancel the lease if the tenant is willing, and a restraining order preventing the husband from extending or renewing any of the leases and against entering into any new leases. Good luck. Dana
