No. That's ordinary negotiations. A tenai is when it's something you don't have control over. 'This get is good if the Broncos win the superbowl.' 'if the dog has puppies' Something not in the behavior of the 2 parties divorcing.
Then, I have a question:
Even then, obviously they will do the best they can and keep to the terms,
however, if they'd both remarry and then decide that they want a webpage up again,
or something else that they had agreed to keep to. That wouldn't make it as if they hadn't
gotten divorced, correct? It would just mean that after 10 years they broke one of the terms - is that a tenai?
