At what point do I involve the title company in probate flip?

[David Kirsch]

Dear Community,  

    Please excuse the amateur questions.. I'm just starting out in wholesaling, particularly in the probate niche. As far as I know I have all the bases covered and am ready to hit the ground running save for 3 questions..

   1.) When I have party 'A' ready to sign the option-to-purchase agreement -- How should that be done formally? Shall I bring 2 copies and have party 'A' and myself 'B' fill out both copies and have each respective party leave with a copy? Should it be brought to a title company? I'm a little confused what to do with the agreement once I have a willing party..

   2.) When party 'C' is interested, do I have them sign something acknowledging their interest for the transactional funder and/or title company?
  
   3.) Assuming I do not need to involve the title company with the option agreement referred to in question 1; At what point do I involve the title company to move forward with the double-close or assignment? As soon as equitable interest is gained on my part? or after I find a buyer (Party 'C')?

Many thanks ahead of time!
