A person can play a basically Lawful and Good paladin without writing it on his sheet. He can also play a Paladin with no alignment whatsoever and act accordingly in the vein of which religion he worships. A Paladin of Love (for example) would certainly be different than a Paladin of Justice, but mechanically (in-game) they're identical, and they shouldn't be.
Those would all be examples of the putting "something equivalent in their place" that I mentioned.
The thing is, as written the Paladin is an odd fit with D&D. The inspiration it is drawn from is largely that of the knight errant, the Knights of the Round Table, the Peers of Charlemagne, and the like. But in each of these instances, the source material is generally tied quite tightly to Christianity. By contrast, the core rules assumptions in D&D about divinity are rather differently. Essentially, the paladin is a monotheistic class in a polytheistic world. As I said, it's an odd fit.
Now, personally, I really really hate the notion of Paladins of every alignment. I further argue that most paladins should, in fact, not be bound to any god, state or race, but rather should serve the forces of Good directly. And, as such, the paladin code should not make more than minor allowances for the fact that Tordek is a dwarf, and dwarves hate orcs with a passion (for example). Frankly, if it came to that, I would rather see the Paladin class retired, and replaced by a Holy Warrior or Crusader class tied to <whatever> (as done in Arcana Evolved). I'm also of the opinion that it is time for the Paladin to become a Prestige Class.
However, I will readily conced that the paragraph above is all personal opinion, and has no basis in the RAW.
I agree, except for the last part; in essence, isn't ceasing to be LG the same as willing committing an evil action(s) and/or violating their code of conduct?
I don't think so. I would suggest that a 'Paladin' who basically did nothing all day, every day, and who consequently never committed an evil act, nor grossly violated his code, would still eventually cease to be Good and become Neutral (since inaction is always Neutral). I'm sure there are other cases, but they're probably pretty minor.
In any event, the three conditions I gave (any evil act, grossly violate the code, cease to be LG) are the same three conditions given in the PHB.
