[quote]My stbx only has our daughter about 10% of the time. But he wants 50-50 legal rights when it comes to making decisions about her. When parents have equal rights it is unusual for one parent to have most of the physical custody? I'm starting to feel like this isn't fair. [/quote]

What he's talking about is joint legal, which is different than joint physical.

What joint legal means depends on your state. In my state, it means that my ex gets to give his input on major decisions, like surgery (in an emergency situation, either parent can make the choice and had better), whether the kids go to private school or public school, religion.
