The answer to your question is a bit tricky. If you are still an owner of this house, your husband has an obligation to get your approval before he moves any renters into it. You can technically contest the lease, but the renters, as innocent 3rd parties may or may not shown the favor of the court. Still, you are entitled to half the funds from any rental monies. As far as changing the locks, no renters are allowed to do that and your husband should himself be concerned that this has happened as it means he is not permitted to enter the property either. Landlords are allowed entrance to the leasehold under CA statutes for several reasons, including in the event of an emergency. So the renters are in the wrong here. However, as far as you just being allowed enter any time you want to get your property, you would not be allowed to do that whether or not they changed the locks. You should work out a time with them to pick up your things while they are at the property--you are entitled to these things a they are not allowed to keep them from you. You can deal with the changed lock issue later. If you want to pursue that, you can file a claim against your husband and the renters in small claims court.
