Does the sole Director & Shareolder have the power to decide what to do with company money?

My x-wife is taking me to court with the claim that a rate refund cheque which was issued in my name, (although when refund was made I no longer was a Director or a Shareholder), should be paid to her.

The cheque was initially issued in my name because when I was the sole director the business rate account was in my name, hence the refund cheque was issued in my name.

As the refund belonged to the company I aked for the cheque to be re-issued in the name of a third party, as instructed by the new sole director and shareholder.

Who would this refund legally belongs to? Surely not me.

Is there any part of the act that states wether the new director was within her rights to ask for the cheque to be issued in the name of a third party?

If not, is there any part of the act that I can reffer to in the court to say who does the money belongs to?
