If brought to trial, Mother Gothel would be sentenced to life in prison for kidnapping Rapunzel. Rapunzel would be considered an "internationally protected person" because she is the daughter of the king snd queen of Corona.
Kidnapping is a first-degree felony. But Flynn Rider would only get nine months to five years for stealing Rapunzel's tiara. The crime Flynn Rider would be charged with would be aggravated theft, which is stealing an item between $150,000 and $750,000 (Rapunzel's tiara would cost $200,000, according to Forbes), a third-degree felony.
