If a child was born in one state over 10 years ago but now resides in another state, which state's laws apply to challenging paternity? (I.E. child's birth state only allowed paternity to be challenged for 2 years after birth so family was not at risk of 3rd party challenging paternity of child born into a marriage, but now they have moved to a new state that doesn't have time limit on when one can challenge paternity... So, which states laws apply?)
