Do I have rights to pay this unit off and enter it to recover my children’s and my belongings if the unit is in his name only?

My husband obtained a storage unit that includes all of our household belongings including the children's who are in my care. He has defaulted on payment of the unit several times and we shared the responsibility of the unit over the last 3 years. The unit is getting ready to be auctioned off, and through a protection order I gained, I am not able to speak to my husband about this. My husband is not returning the storage unit owners phone calls, and is in hiding. I am filing for a legal separation on October 10th 2013 but do not want the chance of losing my children’s stuff. They have been through enough tragedy lately. What do I do? Please help. Thank You.
