IIRC, it didn't have Anna's signature on it...and I think Larry took it to an attorney and asked if it was valid...They said NO and then he went public as the baby's daddy.
Remember...any monies Larry was paid as a DONOR had to be "hidden". So what's new in the world of Howard?
I agree with your take on the 1/6/06 agreement.
Just more speculating here:
*HK$ was well aware of Anna’s desire to have a baby girl. *HK$ had no control over the *Hattens* in her life - I’m sure he didn’t want a repeat of that earlier episode.
*HK$ had LB’s CV and arranged the introduction! A perfect ploy! He looked right, he was not a potential husband and he needed money! LB could be easily absorbed into the *group* as Anna’s exclusive, personal photog. I’ll bet LB was HK$’ choice before he was Anna’s.
