How does the court divide the property? UK Cohabitation Disputes

[@SaleemRaja-x3y]

Dear Sir, I have property dispute where it was agreed that my late parents property was transferred in a siblings name to hold in trust until such time our parents were deceased. Thereafter to sell and distribute shares etc. The sibling has failed to cooperate as she has deceived parties with intentions they had and reliance. How can I obtain a court declaration of beneficial interest in UK and which court would this be filed and under what jurisdiction? What is the legal standing of the registered owner..e.g a representative/administrator / etc.
