Once you notify Agreeable you have finished your agreement [DON”T SIGN IT YET], we provide that to the independent lawyers (one for one person; another for the other).
First, one lawyer explains the effects and implications of the agreement to you and certifies they have done this before you sign. Once that is done, the lawyer sends the agreement to the other lawyer. The other lawyer explains to your partner the effects and implications of the agreement and certifies they have done so before your partner signs. It’s done.
