Your question is difficult to answer. If one is the prevailing party in a civil matter for declaratory relief and the court finds that you, for example, are the rightful owner of a business, I'm not sure how that evidence could be used to prosecute another person for "taking over a business." I would need to know more facts as to how that other person committed theft of a business before answering any questions about whether such conduct is in fact criminal in character.
The evidence of prior proceeding can be used. However, just wining the case in civil court does not mean that they would meet the standard used in a criminal proceeding. Note that civil and criminal court apply different standard of proof.
A conviction in criminal court can be used as presumptive evidence in a subsequent civil case, but not the other way round. However, depending on the facts, evidence from the civil case could be persuasive evidence in a subsequent criminal one.
