That bill was primarily about finances (assuming you’re talking about the alimony law) and little about “tender years” doctrine.
And now urged Florida to build a committee too look at how to change the law smartly, not insist it stays the same. I’m not in Florida so I can’t speak to specifics of law, but this is a far cry from insisting that they keep the tender years doctrine.
The tender years doctrine came about in a time where women were treated like property more than equals. Mother’s had almost no chance of staying with their kids in a divorce, no matter what. So someone made a bad law because it was a shortcut to getting an outcome. The last thing we need is another bad law to shortcut to an outcome.
