[Morgeruat]

Paladins are a human Ideal, the epitome of chivalry, and romantic society, they are bound by two sets of laws, the laws of their god(church or order), and the laws of the land, when the two are in conflict the laws of their god almost always prevail, however as Paladins are lawful beings if there is a law they do not agree with, they work within society to correct it, or change it, by petitioning the rulers, nobles, merchants or anyone with any kind of sway that can be converted to their ideology to correct the laws, only in the case of a lawful/chaotic evil ruler would they actively break the laws, likely causing the people to revolt against tyranny.

also, forgotten realms Paladins don't worship all three gods, Tyr, Torm, and Helm, they usually revere one of them as their patron, and respect the others, there are also paladins of Ilmater or any other lawful good diety, or in some rare cases, such as Helm, Lawful Neutral gods
