CO may not be able to order property division, either.
If OP's STBX does not have any contacts of their own with CO, unless STBX consents to CO jurisdiction over any property division (either directly or indirectly, i.e. accepting it via response), any orders a CO court issues would be void at the outset.
So PA may be the only state that can perform full property distribution. Whatever state is the residence of the supporting spouse (in addition to PA) would be able to order spousal support, if warranted.
