One partnership made by two trustee of two family trust. They made agreement with me. Partnership owe some money to me. I want to sue them. But problem is I cannot find out trustee names. My question is how can i find out trustee name? Or can I just sue them according to the partnership name on ABR ” The trustee of …… family trust & Trustee of ……family trust”(That is partnership name)? They have Business name registered. Any advice will be appreciated.

Thanks in advance.
