Costs Order

[PinkPlum]

Ok, little bit of advice pls from those who may have experienced the same - I am the petitioner. Decree nisi being pronounced v soon with an order for ex-h to pay my costs of divorce (unreasonable behaviour). He is going to be defending the order for costs saying we should each pay our own. He didn't really have much in the way of costs. I will be attending to make a submission that he should pay my costs of the divorce (about £800 plus VAT)
Has anyone been through similar and succeeded in getting an order for costs in this way?
Thank you :)
